The pre-shredder breaks open the plastic bags and reduces the waste material to the optimal size for more accurate sorting.

Excellent uptime

The M&J B240 bag-opener 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 B240 bag-opener 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 B240 bag-opener 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 program and 2 custom program, allowing for tailored shredding routines for maximized performance.

Advanced design

The M&J B240 bag-opener 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 B240 bag-opener has been designed to require less power to operate, thus minimizing energy consumption without sacrificing output.

Versatile applications

Plastics bags and light packing materials vary from country to country. The M&J B240 bag-opener can be adjusted to suit all bag-opening needs. The pre-shredder has been designed to ensure that all bags are opened, while any recyclable materials retain their shape, regardless of the type or composition of the packing material.
