|STRAW PROCESSING SHREDDERS PAGE
|Cormall offer two types of straw shredder, the traditional Tub Shredder in two models (RBS 260 or RBS 300) or the latest MTX-H Mixer Shredders in five models from 18 to 50 cubic metre capacity
Multi-Shredders are provided with electric motors and incorporate a chopping system giving high capacity with economic power consumption. Chopped material is discharged through the stone trap, where the mechanical transport stops and the pneumatic transport takes over.

Multi-Shredder RBS 260
The Multi-Shredder RBS 260 is available with 1 or 2 rotors, each of which have 76 shredding knifes.
Capacities range from 1500-3000 kg/h.
Grid adjustment determines the capacity (t/h) and the shredding length of the straw.

The RBS 300 is equipped with shredding 2 rotors, each with 82 knives.
Capacities range from 4500-8000 kg/h.
The adjustable shredding grid is placed above the rotor to determine the capacity (t/h) and the shredding length of the straw.
Cormall MTX-H Mixer Shredders
This range of heavy duty shredders was developed for the industrial and commercial markets to help process straw and reduce fire risks. The principle is based around our proven range of diet feed mixers but the large diameter mixer augers have knives and a shear bar added to help break down large bales and cut the straw before it goes to the Hammer Mill.
The advantages with this system are:-
Back to the top of the page.
- No fast running rotors with knife blades to cause sparks
- Mixer augers are slow running and cannot be damaged by stone in the bales
- Material not exiting mixer through the outlet door is re-cycled and ground down further before it gets to the hammer mill
- The Mixer is able to handle higher moisture content straw and mix this in with good straw
- No high speed rotors with bearings to overheat
- Mixer is more flexible for handling other biomass materials
- Less power requirement
- Less noisy and less dusty
- Less maintenance - fewer moving parts - cheaper running costs
Bales are fed into the shredder by our range of BT feed tables where strings are removed first.
Two large diameter contra-rotating augers with knives then tear the wads of the bale apart and drop them down on to the augers below (see picture below left).
The augers work at an angle of approximately 28 degrees to re-circulate and break down the straw.
Straw is constantly being cut by the knives on the augers (see picture below centre).
Straw exits the mixer through a hydraulic door into a transfer auger.
It then goes through a 'Scratcher' which helps break up any wads or lumps (see image bottom right) before finally exiting through a stone trap to the Hammer Mill.
