Leftovers from industrial production to be processed
Industrial solid waste

What to check before selecting a shredder for mixed industrial offcuts

Material composition, maximum size, impurity content and target discharge determine the tool structure, drive configuration and subsequent sorting route. Mixed material projects should first complete sample testing.

Centrally recycled waste wires and cables
electronic waste

Cable recycling is not about shredding as finely as possible

The discharge particle size needs to serve the subsequent sorting of copper, aluminum, plastic and other components. Excessive crushing will increase dust and energy consumption, and may also reduce sorting efficiency.

Thin scrap metal awaiting recycling
metal recycling

Why light-gauge and mixed metals need different shredding settings

Material thickness, bulk density and the proportion of mixed non-metals will affect the feed stability and equipment load. The entire line needs to be configured in conjunction with iron removal, sorting and finished product collection requirements.

How to protect downstream equipment when shredding nailed wood pallets

The nails and connectors in wooden pallets need to be fully considered in the workmanship. After stable shredding, combined with magnetic separation and screening, it can create conditions for granulation, fuel or board feedstock preparation.

Waste plastic films packed and stacked
plastic recycling

What to solve first for continuous feeding of film and woven bags

The difficulty with soft plastics is not just breakage, but unstable feeding caused by fluffing, bridging and entanglement. Stable feeding is often more important than increasing instantaneous power.

Waste PE plastic pipes waiting to be processed
plastic recycling

PE pipe and thick sheet: feed whole or cut to length first?

Pipe diameter, wall thickness and length together determine the feeding method. Cutting into sections first is not necessarily more efficient; the entire feed must also be constrained by the boundaries of the equipment.

Centrally recycled waste plastic pallets
plastic recycling

Why hopper design for plastic pallets is more than length and width

Pallet rib position, stacking method and forklift loading rhythm will all affect the material bite. Hopper design also considers height, angle and bridging prevention.

Plastic machine heads and chunks in the recycling yard
plastic recycling

Do thick purge lumps and plastic blocks need pre-shredding?

The thickness, weight and cooling state of the bulk head material determine whether it can directly enter the shredder. The purpose of pre-breaking is to control the boundary rather than increase the process.

Scrap car tires stacked in recycling yard
tire recycling

Must primary shredding fully remove steel from passenger-car tires?

The coarse crushing stage is mainly responsible for reducing the volume and releasing some steel wires. Whether the separation is complete depends on the subsequent target of rubber particles or rubber powder.

Used truck and bus tires awaiting disposal
tire recycling

How to pretreat truck and bus tires with heavy bead wire

The thickness of the bead wire and rubber of truck and bus tires is higher than that of car tires. Drawing, cutting or direct shredding should be selected according to the purpose of the entire line.

Large scrap tires after use by mining and construction vehicles
tire recycling

Why OTR tires usually require staged size reduction

The size and weight of engineering tires are much larger than ordinary tires, so hoisting, cutting and segmented crushing need to be considered as a complete system.

Beads and steel wire rubber blocks separated during tire processing
tire recycling

How to release bead wire without compromising rubber granule quality

Insufficient release of the bead wire will take away the rubber, and excessive fine crushing will increase energy consumption. The magnetic separation position and material return logic need to be coordinated.
