Activated-carbon factory equipment and products

Agricultural & Wood Waste to Charcoal / Activated Carbon

Agricultural shells and clean wood-processing residues can be converted into charcoal or activated carbon through feed preparation, drying, controlled carbonization, gas recovery, cooling, crushing, activation, grading and packing. Coconut shell, palm kernel shell and sawdust require different preparation and operating conditions. Treated or contaminated timber is excluded unless…

Main equipment: Feed preparation, dryers, carbonization kiln, gas recovery, controlled cooling, activation, screening and packing.

Municipal Solid Waste Sorting & Treatment

Municipal-solid-waste plants must accommodate variable organics, plastics, paper, glass, metals, fines and moisture rather than a single nominal feed. Receiving, bag opening, screening, manual or automated sorting, metal recovery and residue handling are balanced with odor, dust, fire and leachate controls. Recovered fractions and any RDF route are…

Main equipment: Bag opener, trommel or screen, conveyors, sorting cabins, magnets, optical sorting and balers.

Waste Plastic Recycling

Plastic-recycling design begins with polymer mix, form, labels, dirt, metal, moisture and the required flake or pellet specification. Sorting, crushing, washing, density separation, dewatering, drying and optional extrusion are selected as one material-balance system. Water reuse, wastewater load, drying energy, incompatible polymers and contamination limits remain project-specific until…

Main equipment: Sorting station, crusher, wash line, friction washer, float-sink separation, dryer and optional extruder.

Real waste-tire recycling equipment

Waste Tire Recycling

Waste tires are received, prepared, shredded and separated to produce rubber chips, granules or powder, with steel and fiber collected separately. The gallery presents feedstock, equipment, factory-video frames and recovered rubber products. Final capacity and product size depend on the tire mix and selected mechanical route.

Main equipment: Debeader, primary shredder, magnetic separator, fiber separator, granulator and classifier.

E-waste processing reference

E-waste Recycling

E-waste treatment requires safe depollution and controlled dismantling before size reduction and material separation. Battery, capacitor, refrigerant, dust and hazardous-component handling are defined first; shredding, magnetic, eddy-current and fine separation follow only where the feed and recovery objective support them. The final route depends on product categories, manual…

Main equipment: Safe dismantling stations, shredders, magnetic and eddy-current separation, fine sorting and dust collection.

Waste glass: feedstock, processing and cullet

Waste Glass Recycling

Waste-glass recovery is designed around glass type, laminate or coating, ceramics and stones, metals, plastics, fines, moisture and the required cullet specification. Automotive laminated glass may require dedicated PVB interlayer separation, while flat and container glass follow different sorting and contamination controls. Crushing, screening, metal removal, air separation,…

Main equipment: Receiving and sorting conveyors, crusher, screen, magnetic and air separation, laminated-glass interlayer separation, dust collection and cullet storage.

Waste textiles: raw material, opening line and recovered fiber

Waste Textile Recycling Line

Before Input: baled waste textiles and used garments compacted by hydraulic baler. Processing: shredding pretreatment, multi-roller opening, cleaning and dedusting, with pneumatic fiber conveying and dust collection. After Output: recycled cotton fiber that may be used for non-woven fabric, felt, insulation or re-spinning when the verified fiber composition…

Main equipment: Hydraulic bale receiving, shredding pretreatment, multi-roller opening and cleaning machines, pneumatic conveying, dust collection and recovered-fiber handling.

Real construction waste and processing equipment

Construction & Demolition Waste Recycling

Construction and demolition waste varies from concrete, brick and asphalt to wood, metals, soil, gypsum and unwanted contaminants. Pre-sorting, screening, crushing, magnetic removal, air separation and optional washing are combined to produce defined aggregate fractions and controlled rejects. Feed source, reinforced material, fines, moisture, hazardous inclusions and local…

Main equipment: Feed hopper, pre-screen, crusher, screens, magnets, air separation, washing where required and aggregate storage.

Medical-waste treatment route references

Medical & Regulated Hazardous Waste Treatment

Medical and regulated hazardous-waste treatment begins with legal classification, source segregation, sealed collection and traceability. Infectious waste, sharps, pathological waste, pharmaceuticals and chemical waste cannot be treated as one uniform feed. Depending on the waste class and local rules, the route may use sterilization with controlled shredding, pyrolysis…

Main equipment: Sealed containers, traceable receiving, route-specific sterilization and shredding, pyrolysis or thermal systems, high-temperature incineration where required, flue-gas treatment, wastewater treatment and controlled residue handling.
