Choose plastic auxiliary equipment by starting with the material you will recycle, the required output, and the process steps needed to turn incoming waste into saleable material. Then match each machine—such as a crusher, conveyor, washer, dryer, or screening unit—to the capacity and operating conditions of the complete line, rather than selecting equipment in isolation. The right configuration depends on factors including plastic type, contamination, feed size, target flake or pellet quality, available utilities, and the space in your plant. Before requesting a quotation, prepare a process description and share representative material details with potential suppliers.

Begin by describing what enters the line. Identify the polymer where known, the form of the feedstock, its typical size, and the kinds of contaminants present, such as labels, soil, metal, or residual liquid. Also explain whether the input is consistent or varies between batches, because material variation can affect feeding, crushing, washing, and separation.
Next, define what should leave the line. Your target may be clean flakes, dried flakes, or material prepared for a later extrusion and pelletizing stage. State the required output quality and any downstream process requirements you already know. If specifications are still being developed, tell suppliers which properties are confirmed and which remain open for evaluation.
Share photographs and, where practical, representative samples. Include the material’s approximate size range, bulk condition, contamination level, and expected variation, but avoid presenting estimates as measured facts. For example, a mixed stream of rigid containers can create different handling needs from flexible film, even when both streams contain polyethylene.
A practical RFQ can use an illustrative design basis such as a required throughput of 500 kg/h, a crusher discharge target of 10 mm, and a finished-material moisture target of 1% by mass. These figures are examples of how to document requirements, not universal recommendations or guaranteed equipment performance. Set actual values according to your feedstock, product requirements, process trials, and downstream equipment limits.
Write down the process stages in order, from receiving material to the intended output. A line may include sorting, size reduction, conveying, washing, separation, drying, and storage, but not every project needs every stage. The appropriate sequence depends on contamination, polymer type, desired cleanliness, and whether the material proceeds to another production process.
The crusher or granulator is often a central part of a recycling line because it reduces larger plastic items into smaller pieces for subsequent handling. Selection should consider feed dimensions, material type, required output size, expected throughput, and how the machine will be fed and maintained. Ask the supplier to explain the proposed cutting arrangement, screen options, access for blade service, and any limits related to the material.
Do not size a crusher using capacity figures alone. A stated capacity may depend on the material, feed form, screen configuration, and operating conditions used for the estimate. Ask what assumptions support the proposed capacity and whether your actual material has been reviewed. If the feedstock changes significantly, discuss whether the design can accommodate that variation.
Conveyors and feeders should move material at a rate compatible with the crusher and later stages. Washing equipment should be selected according to the type of contamination and the required cleanliness, while drying equipment should reflect the moisture target and the next process step. Screens or separation equipment may help control particle size or remove unwanted material, but their suitability depends on the stream being processed.
Review the interfaces between machines, including discharge heights, transfer points, control signals, and material flow. A line can have appropriately selected individual units and still perform poorly if one stage cannot keep up with the next or if material accumulates between machines. Ask for a process layout or equipment sequence that makes these connections clear.

Specify the target throughput and explain whether the line will run continuously, in shifts, or in batches. Clarify whether the target refers to incoming feed or finished output, since losses and process stages can affect the relationship between the two. Ask suppliers to identify the basis of any capacity estimate and which equipment or operating conditions it includes.
Confirm the available electrical supply, water arrangements where relevant, drainage, ventilation, and installation space. Request the proposed equipment dimensions and identify any access needed for inspection, screen changes, blade maintenance, or cleaning. Maintenance access matters in day-to-day operation, so include the people responsible for servicing the equipment in the review.
Ask which controls and protective features are included, and request documentation that explains operation and maintenance. Do not assume that auxiliary equipment, installation, commissioning, spare parts, or operator training are included in a quotation. Compare suppliers using a written scope that lists equipment, interfaces, exclusions, and the information still required before final design.
Another common mistake is treating an early quotation as a final process design when key information is missing. If the supplier has not seen a representative sample or received a clear feedstock description, ask which assumptions were used. Resolve open questions before confirming equipment scope, especially when they affect capacity, cleaning requirements, or output specifications.
Prepare a concise project brief that covers feedstock, target output, throughput, working schedule, plant conditions, and known constraints. Include photos or sample information and note whether the material varies seasonally or by source. This gives suppliers a clearer basis for discussing suitable equipment and helps you compare proposals on the same requirements.
Request a process flow description, a list of included machines, and the key operating assumptions behind the proposal. Ask how the supplier will address uncertain material characteristics, what information is needed to refine the design, and which options can be added later. For a crusher-focused review, discuss feed opening, discharge size, screen selection, blade service, and material-handling interfaces in the context of the full line.
Tuojie supplies plastic auxiliary equipment and can discuss crusher requirements as part of a broader recycling-line configuration. When you share the material type, feed dimensions, target output, throughput, and site constraints, our team can review the information and clarify which details are needed to assess a suitable proposal. Equipment configuration and support scope should be confirmed against the requirements of each project.
For a practical first discussion, send a process outline, representative material photos or samples, and your main operating targets. If some values are not yet established, mark them as provisional rather than guessing. This helps focus the supplier conversation on the decisions that matter and reduces the risk of comparing proposals built on different assumptions.
The best way to choose plastic auxiliary equipment for a recycling line is to define the feedstock and output first, map the process stages, and then check that the crusher and supporting machines work together at the required operating conditions. Treat capacity, particle size, moisture, utilities, layout, maintenance, and supplier scope as connected decisions rather than separate purchasing details. Use representative material information and written assumptions to make proposals easier to evaluate.
Your next step is to prepare a short project brief and share it with suppliers for technical review. Include what you know, identify what still needs confirmation, and request a clear explanation of the proposed configuration and its assumptions.
