First, ring die pellet machine like football development history, is by a Chinese invention, but more and more depression, and Europe introduced our ring die particle machine technology, the ring die particle machine for further reform, the technology into the European patent. And international in our country not learning ring die particle unit, have been using flat die granule machine, but then is to use flat die particle machine to produce feed, as we all know, flat die particle machine used to make feed than ring die production of, hence ring die particle machine actually become popular, probably in reform and opening up, China began to large-scale introduction of ring die granule machine, until now, ring die particle machine because of its large output, less power consumption, is always the first to concentrate at home and abroad.

           As for international environmental consciousness enhancement, more and more aware of straw, wood chips, city life garbage and so on can be pressed into granule combustion, and the burning effect is very good, in five years European particle machine improvement technology of breakneck growth by starting a ring die granule machine, and into the first popular flat die particle machine to suppress crude fiber and difficult molding material.Only the personal contact to grain machine to describe the wood grain is made of straw ring die well, or flat die particle machine well.
           A, Useful

            1. ring die pellet machine in pressing feed particularly concentrate on is really a good hand, its yield, less consumption, this is flat die particle machine can not match. And flat die particle machine due to its speed is lower than ring die particle machine and other reasons, the output is less than the ring die granule machine, and because of its stress, the suppression of the density of the concentrate is very big, so in this respect ring die particle machine ahead.

             2, concentrated feed raw material is commonly corn meal, etc., big viscosity easy molding, don't need a lot of pressure, and it can be for sawdust, straw, grass meal, waste tires and other difficult forming of rough fiber high temperature granulation and urban living garbage, sewage treatment, animal waste and organic fertilizer granulation, so that need a lot of pressure, ring die particle machine due to its structural constraint, the pressure not to move, suppress these materials will be beyond pressure load, cause mould pressure wheel bearing wear or broken. Flat die particle machine structure is simple, pressure can be adjusted to adapt to the different material in what aspects has big advantage. Another point, although the flat die particle machine structure advantage, wear less, but the crop is smaller, generally in the 300-3000 kg. So I want to use a computer to complete 3 tons of production, can choose ring die granule machine, but this kind of situation is limited to maize straw granulation, corn straw easy to pressure.

              B,design principle

               1, ring die pellet  machine as is known to all, ring die particle machine pressure wheel size by ring die diameter limit, pressure not to move, it is pressed wood chips, such as peanut skin coarse fiber materials, the design of the machine under certain pressure difficult forming, even though some manufacturers in the aspects of materials selection do very in place, but that is due to overload work, the machine wear very big, mould pressure wheel skin needs and
When replacement, and mould can only use once, after cost great.
                2, flat pelletmachine adopts three tapered roller, using a complete steel structure, among a large shaft, the following after heat treatment with the mold, the mold turn drive the above three pressure rotary, pressure adjustable, production stability, bulk density, and mould two sides can use. Flat die wheel diameter size from mould the diameter of the limitation, can increase the built-in shaft space, choose a large bearing enhance roller bear ability, improve the pressure wheel of the pressing force and prolong the life.
                C,Feeding way

               Flat die material itself weight vertical into pressing chamber, ring die materials are made by mechanical force feed, high speed rotating centrifugal distribution into the centrifugal granulating chamber. In addition, flat die particle mechanism grain room has three observation door, material always clear, easy to maintenance. Gear transmission with high efficiency. Now in the market also has two pressure wheel flat die granule machine, such particles machine pressing corn straw is no problem, but its pressure and production is far inferior to three tapered roller flat die particle machine. In the pressure wheel pressure regulation methods, three roller by using thread traditional stringed and woodwind instruments center adjustment, top force of one hundred tons, stable and uniform pressure drop. Two pressure wheel flat die particle machine in regulating need adjustment when connecting two pressure wheel two head, under such circumstances, in a few mm gap to the high side, low side. So two pressure wheel flat die particle machine than three roller practical. Moreover, now in the market also has three pressure wheel flat die pellet machine, the purchaser must be certain three roller steel structure is one of the, is welding on or it is a piece of, three roller is cone or cylinder, cone rotary synchronous, solve the cylindrical roller meaningless wear problem.
