How others have improved profitability and reduced risks?
M&J PreShred Series pre-shredders are efficient waste processing machines used in waste recycling and waste processing applications. They can reduce various types of solid waste from municipal solid waste to industrial, commercial and bulky waste to a uniform shape resulting in more efficient usage, sorting or transportation of waste materials.
An open cutting table. Bi-directional shredding system. Wear resistant materials. Easy maintenance.
Self-feeding. No need for a pusher. Readjusts according to the feed material.
Modular construction. Large cutting table. Aggressive heavy-duty knife assembly. Designed to need less energy to operate.
Can be tailored and adjusted to produce the required grain size of any solid waste material.
Multi-functional M&J PreShred Series pre-shredders
M&J PreShredder Series pre-shredders are designed to meet the special needs of waste recyclers and waste processors who handle materials that vary in size and composition or may contain unknown quantities of steel, stones, concrete or other hard materials.
The product family consists of both stationary and mobile pre-shredders with different specifications and features. Different models can be distinguished by naming conventions, "S" denoting "stationary" model and "M" meaning "mobile" version. The larger the machine is in physical size and potential capacity, the bigger model number it has (e.g M&J Preshred 2000S vs. M&J Preshred 4000S).
M&J PreShredder Series pre-shredders can process multiple waste types such as bulky waste, commercial and industrial waste, municipal solid waste, construction and demolition waste, biomass, wood, as well as baled materials. They are often utilized in refuse-derived fuel (RDF) production, biomass processing, waste-to-energy plants (WtE), and in mechanical biological treatment plants (MBT).
All M&J PreShredder Series pre-shredders feature an open cutting table allowing stones and other hard particles, like metals, to fall through the cutting area. The open cutting table design and bi-directional shredding system increase safety and reduce risk of malfunctions that hinder operations.
The knives and wear-exposed parts of M&J PreShredder Series pre-shredders are made from wear resistant steel, ensuring continuous and long-lasting performance. Bolts and bearings are conveniently mounted away from the cutting area, allowing for easy access and maintenance to reduce costly downtime.
M&J PreShredder Series pre-shredders can be adjusted to any waste processing requirements.
The shredders have a bi-directional knife assembly which runs both clockwise and counterclockwise with equal speed and torque. This feature allows changing the rotation direction when challenging materials are encountered, enabling self-feeding and eliminating the need for a pusher.
M&J PreShredder Series pre-shredders are equipped an intelligent control unit that automatically adjusts shredding routines to processed material characteristics. The control unit has 6 standard programs and 2 custom programs, which permit the creation of tailored shredding routines for maximized performance.
M&J PreShredder Series pre-shredders are constructed modularly. The chassis, conveyor and oil coolers can be adapted to meet individual requirements in either new or existing plants.
All the models have a large cutting table and an aggressive heavy-duty knife assembly. The robust frame is designed to require less power to operate, minimizing energy consumption without sacrificing output.
M&J PreShredder Series pre-shredders are excellent solutions even for the most challenging materials.
Many different assembly possibilities, ranging from different knife shapes to the number of knives, enable tailoring and adjusting the pre-shredders to produce the required grain size of any solid waste material.
The shredding technology of M&J PreShred Series stationary pre-shredders is based on aggressive knife designs and open cutting tables.
These distinct technical features provide outstanding performance when dealing with mixed and challenging materials.
M&J PreShred Series stationary pre-shredders are extremely resistant to wear caused by waste materials normally considered as non-shreddable, such as solid steel, reinforced concrete, and rocks.
M&J PreShredder Series mobile pre-shredders utilize the same shreddig technology as the stationary pre-shredders.
Different models are either track-mounted (on crawlers) or wheel-mounted (on trailer).
Mobile pre-shredders as as efficient as stationary ones, but thanks to the undercarriage, they are easily transportable at a production site or between sites.
