Follow the material

One resin journey, several engineering jobs

The exact order changes by plant and resin. The useful idea is to review the whole flow so one improvement does not create a new restriction somewhere else.

01

Receive

Railcar, truck, gaylord, drum, or reclaimed process material.

02

Store

Silos, bins, mobile hoppers, drying hoppers, and level sensing.

03

Convey & route

Pumps, receivers, lines, valves, manifolds, and SMART distribution.

04

Dry & condition

Dry air, temperature, residence time, filters, and material protection.

05

Meter & blend

Gravimetric feeders, recipes, component ratios, and extrusion control.

06

Feed & recover

Reliable machine feed plus qualified regrind or clean trim recovery.

Controls and data connect the entire system: recipes, routing, pump sequence, alarms, trends, material usage, and remote support.
Core system families

Choose equipment around the material flow

These are starting system layouts, not an online quote. Resin behavior, simultaneous demand, distance, lift, bends, utilities, controls, and future expansion all affect the final design.

01

Central resin conveying & machine loading

Move resin automatically from storage or conditioning equipment to one or many machines. The system must cover peak simultaneous demand—not just the average rate of one line.

Complete ABS MV-Series vacuum receiver for central plastic pellet conveying
Central conveyMachine feedPellets

Vacuum receivers & loaders

A receiver is the vessel that separates resin from conveying air. Central receivers use a shared pump system; self-contained loaders include their own conveying source for simpler stations.

Best when
Machines need automatic, repeatable material loading.
Confirm
Material form, peak rate, receiver volume, filter needs, discharge, and available headroom.
Complete enclosed ABS Tranquility central vacuum pump package
Vacuum pumpVFDLow noise

Pumps, sequencing & pickup-velocity control

The pump creates conveying airflow. Sequence controls decide which receiver loads next, while a variable-frequency drive can adjust pickup velocity for different materials and routes.

Best when
Several receivers share pumps or materials need gentler conveying.
Confirm
Distance, lift, bends, line size, simultaneous demand, resin temperature, and plant noise goals.
Complete ABS SMART material distribution station with verified hose connections
DistributionRecipe checkExpansion

SMART material distribution

SMART reduces common-line piping in complex plants and checks that the selected material source is connected to the correct destination before conveying begins.

Best when
Many silos, materials, pumps, or multilayer destinations create routing complexity.
Confirm
Sources, destinations, hose sizes, pump groups, recipes, and future expansion.
02

Continuous gravimetric blending & dosing

A gravimetric system measures material by weight. ABS meters components continuously, so feeder selection and material behavior matter as much as the blender name.

Complete ABS S3 Simplicity continuous gravimetric resin blender
2–10 componentsContinuousGravimetric

SIMPLICITY continuous gravimetric blenders

SIMPLICITY meters multiple materials at the same time using Lightning vibratory or Thunder auger feeders. Standard base sizes are estimated from 500 to 6,000+ lb/hr, with actual performance dependent on the material.

Best when
Extrusion, compounding, or high-throughput processes need continuous recipe control.
Confirm
Each component’s minimum and maximum rate, bulk density, flow behavior, temperature, and cleanout needs.
Complete compact ABS SL continuous loss-in-weight gravimetric blender
CompactLoss in weightUp to 6 components

SL compact gravimetric blenders

The SL family places integral weighed downcomers (small weighed material hoppers) in a compact frame for throat or mezzanine installation. Current standard sizes are estimated at 200, 500, and 1,000 lb/hr.

Best when
Space is limited and the process needs a compact continuous blender close to the machine.
Confirm
Mounting, headroom, component count, rates, receiver arrangement, and discharge.
Complete ABS Chameleon 2.0 automated blender cleanout system
ChangeoverAuto cleanoutNew blenders

Feeders, discharge & cleanout options

Lightning feeders suit many free-flowing materials; Thunder augers address harder-to-meter materials. Chameleon 2.0 automates draining and cleaning on new blender configurations, while central vacuum cleanout supports broader cleanup workflows.

Best when
Frequent recipes, powders, regrind, or valuable residual material make changeover costly.
Limit
Chameleon 2.0 is specified with a new blender and is not a retrofit for existing units.

Important sizing note: published feed rates are estimates. Very light pellets, flakes, powders, high regrind content, poor-flowing additives, and hot materials can change performance. Representative material testing is the most reliable way to choose feeder geometry and operating range. Weigh hoppers and gravity, vacuum-takeoff, or continuous pressure/vacuum discharge options can be added when consumption data, extrusion control, mounting, or blend transport require them.

03

Desiccant resin drying & material conditioning

Drying is more than heater capacity. The resin must receive the required temperature, low-dew-point air, residence time, and airflow before processing.

Complete ABS Thermal-D TD-Series closed-loop desiccant resin drying system
Closed loopTriple bedHeat recovery

TD-Series Thermal-D desiccant dryers

The TD system uses three indexing desiccant beds and recovers residual regeneration heat into the process-air cycle. Current models cover estimated rates from 24 to 2,000 lb/hr, depending on resin and drying requirements.

Monitors
Dew point, process and return temperatures, regeneration conditions, filters, and alarms.
Confirm
Resin, moisture condition, rate, drying temperature, target dew point, and residence time.
Complete CK-Series insulated resin drying hopper
Residence timeInsulated hopperMaterial flow

Drying hoppers, loaders & filters

The hopper holds resin in the dry-air stream long enough to reach the target condition. Loaders, receivers, filters, and takeoffs must preserve that condition while keeping material moving.

Best when
A dryer needs matched storage volume, controlled flow, and automatic transfer to the machine.
Confirm
Residence time, hopper fill pattern, insulation, return air, fines, and downstream distance.

Dew pointTemperatureTrending

Drying data & process review

A dryer display can show whether air conditions are on target, but the part or pellet outcome still depends on the full material path. Trend dew point and temperatures, then compare them with resin handling and process changes.

Best when
Quality varies by shift, material lot, startup, or time since hopper fill.
Remember
A low displayed dew point alone does not prove every pellet received the required residence time.
04

Controls, routing verification & production data

Automation should make the operator’s job clearer. Start with the decisions the control must make, the data the plant needs, and what happens when a connection or condition is wrong.

Complete ABS central control interface for continuous gravimetric blending
PLC / PCHMIScalable

Central controls & software modules

Allen-Bradley or Beckhoff platforms can coordinate blending, vacuum sequence, pickup velocity, silo levels, extrusion throughput, layer ratios, SMART distribution, and custom plant functions.

Outputs
Operator screens, alarms, recipes, material usage, trends, reports, and selected plant interfaces.
Confirm
Existing PLCs, network standards, tags, recipes, historian needs, access levels, and control responsibility.
RecipeTraceabilityRemote support

Trending, reporting & verification

Use data where it helps an operator act: confirm recipe connections, see material use by order or shift, investigate alarms, compare trends, and support troubleshooting without walking every line.

Best when
The plant needs material accountability, repeatable setup, remote support, or faster fault finding.
Limit
Data quality depends on defined tags, device states, recipes, user practices, and integration scope.

GaylordBarcodeChangeover

Operator-assist and material-verification tools

Box tilters keep material near the pickup wand, while barcode and light-guidance options help identify which container belongs at which source or destination.

Best when
Manual containers remain part of the process but labor, empty-container handling, or wrong-material risk needs improvement.
Confirm
Container sizes, labels, pickup method, operator sequence, floor space, and system interlocks.
05

Railcar unloading, silos & bulk storage

Bulk projects are high-value because every bottleneck matters: unloading time, dust, pump duty, transfer method, silo capacity, level measurement, routing, and downstream demand.

Complete ABS railcar unloading system transferring plastic pellets into storage silos
RailcarDirect pullPull / push

Direct-pull and pull/push unloading

Direct pull vacuums resin from the railcar to a receiver at the silo. Pull/push first vacuums resin to a receiver or cyclone, then pressure-conveys it to storage through a rotary airlock.

Choose by
Distance, transfer rate, number and location of silos, routing, dust collection, and plant layout.
Include
Pumps, filtration, controls, level/weight verification, and safe unloading procedures.
Complete intermediate bulk plastic resin storage bin and support frame
SiloStorage binLevel

Silos, bins & mobile storage

Storage may range from a mobile hopper beside the machine to custom welded or bolted silos. Cone geometry, material flow, access, venting, fill method, and level instruments must suit the resin.

Best when
The facility is expanding, consolidating materials, or reducing gaylord handling.
Confirm
Days of inventory, bulk density, refill schedule, flow behavior, footprint, height, loads, and permits.
Complete ABS dust collection unit range for plastic pellet conveying
Dust controlFilter conditionFilter cleaning

Air filtration and dust collection

Air filtration helps keep fine dust out of pumps and manages collected dust at bulk-transfer points. Differential-pressure feedback can trigger cleaning only when filters need it.

Best when
Bulk unloading, dusty materials, fines, or long conveying cycles load the filtration system.
Confirm
Air volume, dust characteristics, filter media, cleaning air, waste collection, and hazard review.
06

Regrind, clean trim recovery & material protection

“Recycling” can mean very different things. ABS can feed and blend qualified regrind or flake and can repelletize clean in-process film trim; that is not the same as a complete post-consumer wash and recycling plant.

Film trimDirect extrusionIn process

Sasquatch trim-scrap repelletizing

Sasquatch converts clean in-line film trim into pellets that can be evaluated for return to the production process. Current published configurations cover multiple trim rates, with actual output dependent on material and material trials recommended.

Best when
A film or sheet line produces consistent, segregated in-process edge trim.
Confirm

This table identifies equipment families, not final sizes. Published throughputs are estimates and can change with bulk density, particle shape, moisture, temperature, additives, route geometry, simultaneous demand, and operating practices.

Common production environments

The same equipment solves different plant problems

Application review begins with the process because extrusion, molding, and compounding place different demands on blend continuity, material residence time, machine loading, and changeover.

Extrusion, film, sheet & pipe

Continuous gravimetric blending, remote pressure convey, throughput control, layer-ratio control, central conveying, desiccant drying, and trim recovery can be coordinated around a continuous process.

Injection & blow molding

Automatic machine loading, moisture conditioning, compact dosing, gaylord handling, recipe verification, and central material distribution help many machines share labor and utilities.

Compounding, regrind & recycling operations

Powder, flake, filler, fiber, and regrind often require material trials, specialized feeders, dust handling, robust receiver geometry, magnets, and careful blending with virgin resin.

Frequently asked questions

Resin handling questions, in plain language

These answers define the basic equipment roles. Final recommendations still depend on the actual material and plant.

What is included in a complete plastic resin handling system?
A complete system can include bulk unloading, silos or bins, vacuum or pressure conveying, receivers or loaders, drying, gravimetric blending, feeders, routing valves or SMART distribution, filtration, controls, machine feed, cleanout, and qualified regrind or trim recovery. Most plants need only a subset, so start with the material flow and production constraint.
What is the difference between a vacuum receiver and a self-contained loader?
A vacuum receiver is the vessel that separates resin from conveying air and typically relies on a central pump and sequence controller. A self-contained loader combines the loading vessel with its own conveying source or compact controls. Central receivers are useful when many destinations share infrastructure; self-contained loaders can be simpler for isolated machines.
When should a plant consider central material conveying?
Central conveying is worth reviewing when several machines repeatedly need the same resin sources, operators spend time moving or loading containers, machines starve, floor space is crowded, or the plant expects to expand. The design must cover simultaneous peak demand, route distance, lift, bends, line size, filtration, and future destinations.
How is a continuous gravimetric blender different from a batch blender?
A continuous gravimetric blender meters each component continuously by weight as the process runs. A batch blender weighs components into discrete batches before mixing and discharge. The right architecture depends on process continuity, rates, component count, material behavior, mixing needs, cleanout, space, and controls. This page focuses on ABS continuous gravimetric systems.
When is gravimetric dosing preferred over volumetric dosing?
Gravimetric dosing measures actual material mass and can compensate for changes in bulk density or flow. Volumetric dosing meters by displacement and can still be appropriate when material properties stay stable and the application does not require weight-based accountability. The best choice depends on rate range, material behavior, tolerance, reporting, and cost—not on treating one method as universally obsolete.
How do I know whether a resin needs desiccant drying?
Begin with the resin supplier’s drying recommendation and the material’s moisture sensitivity. An application review should include incoming moisture, hourly throughput, drying temperature, required dew point, residence time, hopper size, and how dried resin reaches the process. Heating material is not the same as removing moisture with dry air.
What is the difference between direct-pull and pull/push railcar unloading?
Direct pull uses vacuum to convey resin from the railcar directly to a receiver above the silo. Pull/push uses vacuum to bring resin to a receiver or cyclone, then a rotary airlock and pressure system convey it to storage. Distance, rate, silo arrangement, dust collection, routing, and available space determine which setup is more practical.
Can ABS equipment handle regrind, flake, powder, or recycled content?
Many ABS feeder, receiver, blender, and handling configurations can be adapted for qualified regrind, flakes, powders, fillers, and recycled-content recipes. These materials can bridge, segregate, dust, or vary in bulk density, so representative testing and a clear acceptable-material specification are important. Sasquatch is specifically for clean in-process trim repelletizing, not a full post-consumer wash line.
What causes angel hair in resin conveying lines?
Angel hair forms when pellets soften from heat and friction, then smear or stretch during impacts with pipe walls, bends, or fittings. Excessive pickup velocity, hot material, long routes, and line geometry can contribute. Velocity control addresses formation risk; a trap captures stringers and helps locate where they are being created.
What information is needed for a useful resin handling quote?
Provide the process, polymer and material form, bulk density, normal and peak rates, component percentages, number of sources and destinations, route distances and vertical lift, changeover frequency, moisture and contamination concerns, utilities, floor plan, ceiling height, control platform, reporting needs, and future expansion. Photos and a marked-up plant layout are extremely helpful.
Can the controls connect with existing plant systems?
Often, yes, but the interface must be defined. ABS uses scalable PLC- or PC-based controls and offers software for blending, vacuum sequence, SMART routing, velocity, extrusion functions, silo levels, reporting, trending, and custom integrations. Confirm PLC brands, network protocols, tags, data ownership, alarm responsibility, security, and validation expectations early.
