pellet mill

I.Seven characteristics 1.Vertical feeding directly in place. 2. Die static, roller rotating, materials centrifugal, Evenly distributed around. 3.Double-layer dies, up and down dual-use, reduce the cost,enhance the efficiency, can be dual-use,high capacity,energy saving. 4.One die,different hole diameters, with different specifications to pelletize. 5.Macroporous die, wire joining circular tube, increasing travel, improving density. 6.Ring die,vertical structure,good for cooling the pelletizing room. 7. Independent and frequency conversion discharge device, to ensure that the rate of pellet formation. II.Four differences 1.Upward mould, special structure, vertically feeding,easier heat dissipation: the material is feeded into the pelletizing room vertically and is well placed, no other pressing device is needed. The feed inlet of ring die pellet mill is set in one side, so light material is hard to get into the pelletizing room and other special force pressing device is needed, what’s more important, the lifetime of gearing(gear, bearing) is shorten as the pelletzing room couldn’t dissipate the heat and be cooled. Flat die pellet mill has two structures, but both have many disadvantages that are hard to get rid of even they can be feeded vertically. (1) die rotates to make rollers run, the output will be effected as material is easily arched which lead to uneven feeding. (2) When the rollers rotate while the die is static, which could avoid the arching of material, but centrifugal force is caused which will swing the material in the pelletizing room to the periphery. And that will cause the upward flat die with evenly distributing pellet holes in it has no material to press in the center, then material piles up unevenly in thickness. 2. Die static, roller rotating, material centrifugal and distributed around evenly: using a unique double-layer high rebounding-effect die,naturally and evenly distribute in the die’s inner surface.Normally ring-die pellet mill’s rollers are static, die rotates, no centrifugal force,unevenly distributed material.Normally flat-die pellet mill’s rollers rotate to generate centrifugal force, but the die hole is inconsistencies with the material force.
