Structure of DRZL650 3.5t/h wood press machine

1. Feeder&Observation Hole:
Variable Frequency speed control, observation window to inspect the pelletizing at any time .

2. Forced feeder:
The average quantity is fed to the main engine at a constant speed.

3.Pelleting Chamber:
Insist of two rollers, ring die, and fixing parts.

4. Safety device :

the safety pin and switch is equipped to protect main shaft and stop the electric when iron go into the chamber .

5. Ring die lifting device :

Roller shell and Ring die replaced easliy with lifting device

6. Ring die :

Customized raw material and imported processing equipment and profession heating treatment compared to others .

(Compression Ratio= L/D L: Effective Die Hole Pelleting Length; D: Effective Die Hole Dia)
Generally speaking, the higher the compression ratio, the denser the finished pellets. But it does not mean that the higher the compression ratio, the better the pellet quality. Compression ratio should be calculated based on your raw material for making pellets. Commonly compression ratio is inversely proportion to the hardness of raw material, the harder the raw material, the smaller the compression ratio.

7. Reduce Box

Including main shaft ,hollow shaft ,gear ,gear shaft .

Machine Center :650 and 880 is processed in machine center :

Processing machine :Korea DOOSAN Large Processing Center,Germany NILES gear grinding machine,LGMazak Little Giant CNC Turning Center,Samsung Turning Center PL35M,Gear accuracy tester T-600,Germany Three-coordinates measuring machine for body tester .

How to work of wood press machine

The material in the granulation bin is fed into the chute by the feeding auger, the material enters the pressing chamber through the forced feeder, and is fed into the two pressing areas in the ring die by the feeding scraper. Due to the high-speed rotation of the ring die The material is brought between the ring die and the pressure roller. Under the strong extrusion action of the ring die and the pressure roller, the material is gradually compacted and formed in the die hole. Because the extrusion of the material between the die rollers is continuous , so the formed material is continuously discharged from the die hole in a columnar shape, and then cut into particles of the required length by the cutter, and then enters the next process.

The Spare parts

1. Ring die :Pellet dies must resist abrasion, corrosion from chemical exposure and breakage caused by the physical stresses of pellet formation. The optimum die combines high resistance to abrasion, breakage and corrosion with maximum productivity. Our expertise enables us to precisely match the die specification to your required formulation, even if it means customizing a die pattern to meet your exact needs.

2. Roller shell :

Each die and roller assembly stay together as a unit, extending die and roller life and enabling easy storage and conversion.

Raw material :alloy steel .

Others such as five piece cover ,o ring ,main shaft etc .
