Four Shaft Shredder (RDF Shredder)
The discharge port for abnormal raw material
Only if there is hard rock, concrete, metal or raw material difficult to shred, the port can be opened automatically to clear the abnormal material by counter-rotating the two rollers, besides this discharge port can be used for maintenance
Shredding Chamber
The two opposite ways of opening design for the housing of the shredder and the bearing units that are installed externally will facilitate the maintenace. The liquid and dust will pollute the bearing and affect the service time. And the movable wearing plate of NM550 material will assure the anti-corrosion and the wearing of the shredder.
Main Shaft
The forged type alloy is used to make the shaft so the tension and hardness can be assured. The tungsten carbide wearing layer is welded into the surface of the shaft, and the static shaft has function of the anti-wrap to avoid any fiber or textile to wrap the shaft and jam the shredder. The guidance sliding plate is installed as extension of the main shaft and the static knives will control the discharge size of raw material.
The seperated hydraulic driving system will function well the two ways of rotation of the roller. Both way of rotation will shred the raw material.
Allocation of the Knives.
The knives can be allocated as L,V,S,X method according to various raw material. Different type of allocation is used to avoid any stacking and bridge building for raw material, and the raw material will not be shredded all the time.
Knives
The material for knives can be two types: One is Wearing Plate HRADOX imported or WNM made in china. Different material will vary different type of knives, and the seat of knives can be movable and the seat can be welded to roller, both way are designed for easy maintenace.
SEAT of Knives
The movable seat of knives is installed according to the pin on the groove and locked by the bolts. So the accuracy is high and can be used for heavy duty, the knives are easy to replace for the maintenace.
Axial shaft+Reducer
The wide range of the variable hydraulic motor will comply with the request of high speed and high torque. The reducer without gear will save the space and cost. The special bearing system will extend the service time of the shredder and the good start-up of low rotation moment will be assured. The output of torque will increase by the pressure difference of the two side of the hydraulic motor and increase by rising up the discharge capacity of the variable motor.
