Size Reduction for Bulky Waste

Size Reduction for Bulky WasteSize Reduction for Bulky Waste
Recently, size reduction for bulky waste has become an extremely important issue in the recycling industry due to the growing demand.

Stokkermill offers recycling plants for electric motors, starters, alternators, copper meatballs, and refrigerator compressors. Stokkermill has been developed advanced and customizable recycling systems consisting of Hammer mills, refining plants, and sorting systems. The Hammermill shredder is suitable for the first reduction in order to obtain the right size of output materials for the refining step. Stokkermill bulky waste recycling plants are designed to ensure high standards both in terms of reliability and long-term productivity. Stokkermill bulky waste recycling plants for size reduction can guarantee high standards of quality for output materials and for the production of high-purity copper, using a Hammermill shredder as the first reduction, then refining plants and sorting process depending on the customers’ needs.

Hammer Mill industrial shredder HM of Stokkermill’s range is systems for reducing the size of incoming materials, in order to allow subsequent separation and cleaning operations with the aim of maximizing the commercial value of the output materials. Hammer Mill shredders HM series are especially suitable for processing electric motors, refrigerator compressors, copper meatballs, alternators, and metals refining. Stokkermill designs and manufactures small and medium-sized hammer mills that are characterized by their robustness and simplicity during maintenance operations thanks to the hydraulic opening system of the crushing and rotor lifting chamber or the replacement of the classifier screens.

The simple construction and the use of high-quality materials guarantee the durability and reliability of the Stokkermill hammer mills for electric motor recycling. Hammer Mill shredders HM series can be equipped with an inverter to optimize the rotation speed according to the material to be processed; a particular system for anchoring the crusher to the base allows reducing the vibration. A safety system allows the automatic ejection of any foreign bodies, avoiding damage to the rotor and the crushing chamber.

Stokkermill hammer mills can handle a very wide range of materials:

  • Hammer mill for collection scrap
  • Hammer mill for aluminum profiles and casings
  • Hammer mill for collection aluminum scrap
  • Hammer mill for electric motors and engines
  • Hammer mill for engines coming from the demolition of vehicles
  • Hammer mill for refrigerator compressors
  • Hammer mill for alternators, starter motors, and copper meatballs
  • Hammer mill for separation of the harmonic steel from the ELTs
  • Hammer mill for copper, aluminum, iron radiators
  • Hammer mill for crushing residues (car fluff, Zorba, Zurik)
  • Hammer mill for electrical and electronic equipment (WEEE)
  • Hammer mill for medical equipment
  • Hammer mill for toner
  • Hammer mill for tins

Also, the size reduction equipment for WEEE is turning out to be one of the most attractive and profitable opportunities on the market; the quantity of the material to be recycled tends to grow with the increased spread of electric and electronic equipment, with the implementation of regulations aimed at improvement and mandatory treatment practices. Currently, major parts of electric and electronic waste (E-waste) are landfilled and the waste generated is expected to grow by 20% in a few years. E-waste has been classified as a priority waste to treat, therefore, it is extremely important to think about the proper recycling system of E-waste. E-waste shredding and processing offered by Stokkermill machinery allows processing variable quantities of electric and electronic equipment, privileging technological versatility and flexibility. We offer a twin-shaft shredder for size reduction of WEEE. Industrial shredders for processing size reduction are the starting point when systems are tailored to suit specific customer requirements. The equipment for the recycling of electric and electronic equipment, if properly related to a phase of manual intervention allows recovering the following fractions of homogeneous materials:

  • plastic materials 25-30%
  • ferrous and stainless materials 25-30%
  • metal 12-17%
  • printed circuit boards 6%
  • electrical wiring 1-2%
  • batteries and capacitors
  • undifferentiated mixed waste

The recovery of raw materials from electric and electronic waste (WEEE) generates a growing amount of electronic, which are being put on the recycling market. The treatment and recycling of electric and electronic boards, printed circuit boards, and motherboards allow to recover:

  • metal mix (copper, tin, precious metals)
  • inert and plastic materials
