M&J Pre shredders
Key Features
- Up to 200 tph throughput (M&J 6000S)
- 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
- Power pack and cutting table that can be mounted separately, to keep more delicate components away from dust etc.
- Automatic reversal, if knives encounter large or tough steel or cement objects
- 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 shredding capability and capacity
PreShredder Cutting Table Technology
The Technology
M&J Recycling’s shredding technology is based on extremely aggressive knife designs and open cutting tables. These distinct technical advantages ensure our shredders provide outstanding performance when dealing with mixed and challenging materials. These key features also make M&J PreShred units extremely resistant to wear caused by materials
and waste normally considered as nonshreddable; including solid steel, rein-forced concrete and rocks.
Versatility
All M&J PreShred units feature a modular design approach combining a range of well-proven components to meet your specific application and shredding performance. M&J Recycling’s range of stationary shredders includes five machine types covering a wide range of capacities. Each model is available in a variety of shredding performance levels. Our stationary units are suitable in a wide range of different applications.
The large, rotating knives and the counter knives are all made from 500BHN abrasion resistant steel plate. This material is exceptionally wear resistant, making sure the knives have the longest possible service life.
The knives are solidly welded onto the shafts, making M&J Recycling shredders extremely robust, capable of withstanding impacts from any items that simply cannot be shredded. There are no bolts, bearings or adjustable parts anywhere in the cutting area—which significantly cuts down on the need for cleaning and service.
The shafts can turn in both directions with full torque, and can operate asynchronously. This provides greater capacity and less risk of tangling, reduces bridging and spreads the wear evenly on both rotating and counter knives.
Self Cleaning
A special “self-cleaning” system makes sure M&J Recycling shredders automatically reverse their direction of rotation at pre-programmed intervals. As a result, the shredder loosens any material on the shaft and “cleans” the cutting table—also helping prevent unnecessary wear.
Intelligently Controlled
All the main functions are monitored and controlled by service-friendly PLCs equipped with intelligent software that automatically adjusts operating profiles to match specific types of input flows. This is supplemented by an Anti Jam System (AJS) that protects both cutting tools and power pack from unnecessary damage. The advanced control electronics make it easy to link M&J Recycling shredders to centralized surveillance facilities and control rooms.
Modular Design
All M&J Recycling shredders feature a modular design that ensures effective upgrade paths and highly cost-effective service life extensions. Changing shafts is rapid and straightforward, and it’s easy to swap out the entire cutting table should your shredding requirements change over time.
Downstream Benefits
The advantages of M&J Recycling shredders aren’t limited to the cutting table. In addition to maximum performance in terms of capacity and grain size, the shredding process is designed to ensure consistently even distribution of material on the conveyor after shredding.
