Oct. 28, 2017

Pellet mill machine/granulator can be divided into flat die pellet mill/granulator and ring die pellet mill/granulator in accordance with the different molds. And there are big differences between flat die and ring die pellet mill/granulator.The users should be clear of them and know what type they need to buy.


Wood Pellet Machine


The difference between flat die and ring die pellet mill/granulator


First, pressure of flat die and ring die pellet mill/granulator.

In the same diameter of the mold, the ring die diameter of the diameter of the ring die by the diameter of the mold limit, the pressure is not adjustable, in the suppression of wood pulp peanut skin and other crude fiber materials, the pressure in the machine design difficult to form, even if the formation of super Load work, the machine wear and tear, mold pressure wheel need to be replaced in time, and the mold can only be used once, the follow-up costs are great.


The flat die mold is equipped with a special heat treatment mold, the mold rotation to promote the above three pressure wheel rotation, the pressure is adjustable, the output is stable, the particles are density, and both positive and negative mold can be used. In addition, the size of the flat die roller diameter is not limited by the diameter of the mold, can increase the shaft space The use of large bearings to enhance the capacity of the pressure roller to improve the pressure of the pressure wheel and extend the service life.


Second, pressure roller adjustment mode of flat die and ring die pellet mill/granulator.

Ring die pellet mill/granulator if the middle of the wheel with the pressure on the two screws to adjust the pressure Flat die pellet mill/granulator is the use of threaded wire column center adjustment mechanism, top force hundred tons, smooth landing, soft touch, uniform pressure.


Third, feeding method of flat die and ring die pellet mill/granulator.

Ring die pellet mill/granulator uses mechanical forced feed, high-speed rotation centrifugal distribution into the granulation chamber, through the scraper to distribute materials, feeding uneven.Flat die pellet mill/granulator is the weight of the material itself into the compression room, can be fed evenly material.


Fourth, discharge materials method of of flat die and ring die pellet mill/granulator.

Ring die mold has high speed,the damage rate of materials is high.While flat die belongs to low speed, low damage rate.


Our main products: wooden pellet machine, spare parts of pellet mill, ring die, flat die and roller shells.
