Frequently Asked Questions

Feeders control delivery, screens separate suitable size fractions and spiral conveyors transfer suitable material between levels. Compaction tables may be useful for settling material during filling. We select around the waste stream, including moisture, contamination and variable particle shape. Equipment designed for clean granulate will not necessarily handle mixed bulky waste. Tell us about normal feed and the difficult pieces that occasionally enter the line, because both influence the required construction.

A vibratory spiral moves suitable recyclable material along a helical trough using controlled vibration. This can concentrate a vertical transfer within a compact layout. We assess variable density, irregular pieces, moisture and contamination as well as tonnage. The installation needs safe access and guarding at moving interfaces. The absence of a conveying belt or chain does not remove mechanical hazards, wear or maintenance requirements from the complete system.

We can assess cooling for recycled granulate using polymer type, production rate and measured inlet temperature. The target condition should suit bagging, storage or the next process. Cooling medium, layer depth and residence time determine the arrangement. Recycled material can vary between batches, so those variations are included in the assessment. We define the conditions for the cooling duty instead of promising one temperature reduction for every recycled product.

A screening section can be incorporated where the material and required cut suit the available spiral area. Fines need a separate, accessible collection route. We review distribution, moisture, near-size particles and blinding risk. A dedicated screen may still be necessary for a demanding separation. The decision follows recovery and product quality, not only whether another machine can be removed from the layout.

A controlled feeder reduces surges and presents material in the layer or distribution the receiving separator requires. This gives the next process a more consistent input. Optical sorters, magnets and screens need different presentations, so we use the receiving machine's requirements and peak feed conditions. Recovery and purity also depend on separator performance and material condition. Better feeding supports those results but is not, alone, a guarantee of a particular recovery rate.

Glass cullet can be assessed for vibratory conveying with attention to abrasion, sharp pieces and inlet impact. Suitable contact construction and replaceable wear areas may be needed. We ask about maximum piece size, throughput, contamination and drop height. Covers and discharge arrangements must permit safe inspection and servicing. We compare options for the duty rather than assume a metal trough is immune to wear or always outlasts every alternative conveying system.

Space depends on elevation, throughput, material and conveying geometry. The installed envelope includes the drive, frame, connections and maintenance access, not just the spiral diameter. Recycling applications may need particular access for retained material and wear inspection. Cooling or drying services add their own space requirements. We develop the layout from the duty instead of quoting one minimum footprint for every lift height and waste stream.

Covered equipment can help contain dust and light particles, but film and fibre need a handling assessment because they can interlock, bridge or be disturbed by airflow. We need size range, moisture, contamination and relevant dust-hazard information. Connections, access covers and extraction should work as a system. Enclosure alone is not evidence that exposure or fire risks are controlled. Trials can help confirm the behaviour of a difficult lightweight stream.

A table can settle suitable flake or granulate during filling to reduce later settlement or achieve more consistent occupied volume. We need the material, container arrangement and maximum loaded mass. Checks should include segregation, damage and dust as well as volume change. Compaction does not measure fill weight or permit the container's rated load to be exceeded. Any reduction in container usage needs to be demonstrated for the actual product and filling method.

Surface drying and conveying can be assessed together, but washed flake may first need drainage or another dewatering stage. Water quantity and how it is held determine the treatment required. We need starting and target moisture contents, throughput and acceptable temperature. Air conditions and residence time must support that moisture removal. Elevation alone does not guarantee dry material or reduced downstream energy consumption, so the intended result is defined and assessed separately.
