The right plastic auxiliary equipment solution is a coordinated set of machines that moves, prepares, processes, and handles material around a production line. To select one, start with the material, required throughput, main machine requirements, and operating constraints—not with a list of equipment alone. For processing and recycling lines, a crusher or granulator may be central, but feeding, conveying, drying, separation, and dust handling can also affect how the line works as a whole.

This guide is for manufacturers, recyclers, project engineers, and purchasing teams comparing equipment for a new installation or an upgrade. We explain common equipment types, how to match them to applications, and what to confirm with a supplier before requesting a quotation. At Tuojie, we recommend sharing process details early so equipment selection can be discussed against actual operating requirements.
This guide is intended for buyers planning plastic processing or recycling equipment, including facilities handling production scrap, rejected parts, or post-use plastic. It is also useful when an existing line needs a crusher, dryer, loader, or conveying equipment added or replaced. The right configuration depends on the material and process, so the same equipment package may not suit two plants with different feed conditions.
Purchasing teams can use the selection framework to prepare an inquiry, while engineers can use it to identify interfaces that need review. If you are sourcing a crusher specifically, focus on the feed opening, rotor and cutting arrangement, screen, drive, discharge method, and maintenance access. These details should be considered together rather than as independent specifications.
Auxiliary equipment supports the main production or recycling process by preparing and transferring material, controlling process conditions, or handling output. Depending on the application, a line may include a crusher or granulator, hopper loader, conveyor, dryer, mixer, dosing equipment, separator, or dust collection system. Not every line needs every machine, and equipment selection should follow the process flow.
In plastics manufacturing, loaders and conveyors move resin or regrind to the processing machine, while dryers may be used when material conditioning is part of the process. Mixers and dosing equipment can support the preparation of blends or additives, subject to the production recipe and control requirements. A crusher can reduce suitable clean production scrap for collection or possible reuse, but the acceptable material and particle size must be confirmed for the intended downstream use.
Recycling lines may use crushers or granulators to reduce plastic parts and scrap, followed by conveying, sorting, washing, dewatering, or drying equipment as required by the process. The needed stages depend on material type, contamination, moisture, and the quality target for the recovered material. A crusher alone does not establish that output is suitable for reuse; downstream requirements and material condition must also be assessed.
Begin by describing the feed in practical terms: polymer type if known, whether it is rigid or flexible, typical piece dimensions, bulk condition, contamination, and moisture. Explain whether the feed consists of sprues, runners, rejected parts, film, containers, or mixed scrap. Material names alone may not provide enough information to evaluate equipment, particularly when part geometry or feed consistency varies.
Next, define what the output must do. For a crusher, that means discussing the required particle-size range, whether a screen is appropriate, how the material will be discharged, and whether the output will be reused, stored, or sent to another process. A stated throughput target should be tied to the actual feed and operating conditions, because nominal capacity can differ with material, feeding practice, and configuration.
For example, a buyer might tell a supplier that the line needs to process 300 kg/h of a defined production scrap; this is an illustrative project input, not a general crusher rating. A request might also specify a 10 mm screen aperture as a starting point for discussion, but the appropriate screen depends on the application and desired output. Likewise, a plant with a 380 V supply should state that requirement and confirm frequency, phase, and electrical compatibility with the supplier, since available power standards vary by location.

These example figures are not recommendations for a particular machine. Use measured or documented operating requirements wherever possible, and identify estimates clearly. If the material or target output is not yet fixed, ask the supplier what samples, drawings, or process information are needed to narrow the configuration.
Equipment pricing depends on the selected machines, capacity, configuration, materials of construction where relevant, controls, and project scope. Installation, shipping, taxes, commissioning, and spare parts may be quoted separately, so ask suppliers to identify inclusions and exclusions. A low initial price is difficult to compare meaningfully unless the equipment scope and support terms are clear.
Minimum order quantities and lead times can vary by product, customization, production schedule, and destination. Rather than relying on a general estimate, request a current quotation that states the proposed configuration, production or dispatch timing, and any buyer-side responsibilities. For a line project, confirm whether equipment is supplied as individual units or as a coordinated package and who is responsible for checking integration.
For crusher selection, ask specifically how the proposed feed opening, cutting arrangement, screen, drive, and discharge method relate to your feed. Also ask how routine access and wear-part replacement are addressed in the proposed design. These questions help clarify whether a quote reflects your application or only a standard equipment description.
One frequent mistake is selecting equipment based only on a headline capacity figure without defining the material and operating conditions behind it. Another is specifying a crusher before deciding how the output will be collected, conveyed, or used. Either gap can lead to a configuration that does not align with the full process, even if an individual machine appears suitable on paper.
Buyers can also overlook plant constraints such as access for installation, available electrical supply, discharge height, cleaning needs, or maintenance space. Avoid treating a screen size or motor rating from another application as a direct recommendation for your own line. Instead, provide the supplier with a consistent set of process data and request written confirmation of the assumptions used in the proposal.
At Tuojie, we supply plastic auxiliary equipment solutions and can discuss crusher requirements as part of a processing or recycling line. To help us assess your inquiry, share the material type and form, target throughput, desired output, existing equipment, site utilities, and destination market. Photos, drawings, and a simple process-flow sketch can make the initial technical discussion more specific.
We can use these details to review the requested configuration and identify information that may still be needed before quotation. Final equipment selection should be confirmed against the actual material, site conditions, and intended process. If you are comparing suppliers, request the same scope and operating assumptions from each so the proposals are easier to evaluate.
A suitable plastic auxiliary equipment solution is selected by matching equipment to the material, required output, production flow, and site constraints. For processing and recycling lines, the crusher may be an important component, but feeding, conveying, drying, collection, and maintenance requirements can also shape the overall configuration. There is no single set of specifications that fits every material and application.
Your next step is to prepare a short technical brief with feed details, target throughput, output requirements, utilities, layout constraints, and the equipment already in place. Send it to Tuojie with photos or drawings if available, and ask for a proposal that states assumptions, scope, and exclusions. This gives your team a clearer basis for comparing solutions and moving toward a practical equipment selection.
