M&J PreShred 4000S

Able to handle most tasks

The M&J PreShred 4000S is the mid-sized model of the M&J PreShred stationary pre-shredder family. It can process various waste types such as bulky waste, commercial and industrial waste, municipal solid waste, construction and demolition waste, biomass, wood, as well as baled materials. The pre-shredder is generally used in refuse-derived fuel (RDF) production, biomass processing, waste-to-energy plants (WtE) and in mechanical biological treatment plants (MBT). It is also available as a slightly modified version for bag opening (M&J B240 bag-opener) and as a mobile version.

    Excellent uptime

The M&J PreShred 4000S features an open cutting table that allows stones and other hard particles like metals to fall through the cutting area. The open cutting table design and bi-directional shredding system increases safety and reduces the risk of malfunctions that may hinder operations.

All knives and parts exposed to wear on the M&J PreShred 4000S 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.

    Intelligent performance

The M&J PreShred 4000S can be adjusted to meet all waste processing requirements. Its bi-directional knife assembly runs both clockwise and anticlockwise with equal speed and torque. The shredder can change the direction of rotation when it encounters challenging materials, thus enabling self-feeding and eliminating the need for a pusher.

The pre-shredder is equipped with an intelligent control unit that automatically adjusts shredding routines to suit the processed material. The control unit has 6 standard programmes and 2 custom programmes, allowing for tailored shredding routines for maximized performance.

    Advanced design

The M&J PreShred 4000S has a modular construction. The chassis, conveyor and oil coolers can be adapted to meet individual requirements in either new or existing plants.

The pre-shredder has a large cutting table and an aggressive heavy-duty knife assembly. The robust frame of the M&J PreShred 4000S has been designed to require less power to operate, thus minimizing energy consumption without sacrificing output.

    Versatile applications

The M&J PreShred 4000S is an excellent solution for even the most challenging of materials. Many different assembly options – ranging from different knife shapes to the number of knives – enable you to customize and adjust the pre-shredder to produce the required grain size for any solid waste material.
