NEW mobile PreShredder makes light work of heavy waste

Features

  • Speed of the conveyor belt to be precisely adjusted to suit the waste being processed
  • Ladder mounted at cutting table for easier service
  • Easier and more efficient to operate - larger hopper
  • Easier to lubricate the conveyor bearings, improves maintenance and results in a longer lifespan
  • Remote control is much more intuitive to use
  • More space in the power pack easier to service
  • New touch-screen display is more intuitive to use, and has much better visibility and the PLC is designed especially for mobile unit
  • Extremely aggressive knife design and open cutting table
  • The Intercooler water cooler allows completely flexible adjustments
  • Two position of King pin more flexible to different trailers
  • New power pack cooler keeps the unit operational in temperatures up to 45ºC, increasing the range of use
  • New CAT C15, 403 kW power pack has longer service interval, from 250 hours to 500 hours

Benefits

M&J PreShred 4000M features asynchronous bi-directional shredding technology, which reduces wear and keeps waste constantly, moving in a consistent flow. The M&J double hydrostatic drive is extremely reliable under heavy loads and shocks, and all knives and
exposed cutting table components are made of Hardox 500 wearresistant steel for less wear and less downtime.

A central lubricating system is standard on all machines, and intelligent shredding routines automatically adapt to processed material characteristics. M&J PreShredders perform under the toughest conditions all around the world, and are commonly found in Waste Transfer stations, Landfills, Composting plants, Wood recycling plants, Waste recycling plants and Waste service providers.

 

Advanced technology

Throughput can be as high as 100 tons/hour, depending on the type of input, the number
of knives specified for the cutting table, and the feed set-up. The interaction between the two knives rotating on these two shafts running asynchronously and in both directions ensures that the input material is constantly in motion, thus preventing bridging and providing maximum shredding capacity.

Key advantages of the M&J PreShred

  • Open cutting table reduces wear to the bare minimum
  • Bi-directional shredding results in a consistent flow of shredded material onto down-stream conveyors
  • Asynchronous shredding keeps waste constantly moving, thus improving shredding efficiency
  • With our aggressive knife design, no pushing device is required
  • Central lubricating system is standard on all machines
  • Automatic reversal if knives encounter large or tough steel cement parts
  • Intelligent shredding routines automatically adapt to processed material characteristics. The PLC control system is equipped with six standard programs, including two that can be individually programmed
  • Hardox steel used in all parts of the cutting table exposed to wear
  • Bi-directional shredding with equal speed and torque reduces wear and improves capability and pre-shredder capacity
