Small Flat Die Animal Feed Pellet Mill Machine Working Characteristics
Small flat plate feed pellet making machine to make animal feed is now used by many small scale animal feed mill plant or farms since it has relatively small capacity and does not occupy too much funds or area.
During the operating of flat die feed pellet mill equipment, we find that it has some salient characteristics (or we can say advantages) over other types of small flat die feed pellet mills (like ring die or vertical type ones). Here let's learn together.
1.Material feeding characteristic
The first place that feed raw material enters the flat plate feed pellet making machine for small farm is the feeding chamber. It plays a role of caching and feeding material, and also completes the feeding to the wedge grabbing angle of roller.
The feeding chamber of small flat die feed pellet press has two features:
(1)one is that it has broad feeding space, which can offer sufficient area for big diameter pressing roller and loose biomass material. For example, some materials are light and fluffy, not easy to be fed into the small flat die animal feed pellet maker mill. The broad feeding chamber can rightly offer space for raw material. At the same time, the machine can use roller in large diameters, so that the grabbing angle is enlarged, and its ability of grabbing material is improved. It is measured that the unit weight of powder is about 200kg/m3, and the porosity is around 75%. When making pellets, its compression ratio is about 6 or above, which puts forward higher requirement for feeding chamber.
(2)The other is that the direct feeding method which uses the gravity is highly efficient and practical. As the feeding process utilizes gravity to let the material drop down, so no forced feeding is needed. Such kind of feeding method is superior to ring die feed pellet making machine whose material guide plate parameter shall be changed when processing biomasses with different properties, which also limits the adaptability of ring die feed pellet milling machine to raw material.
2.Flat die characteristic
As the core working part in a pellet mill, the structure parameter of flat die determines pellets quality. For processing different feed material, the small flat die feed pellet press shall be equipped with flat die in different parameters. All factors like the area with holes, hole size, hole arrangement, etc. determine pellets performance. The smaller feed pellet processing machine compression ratio is, the larger productivity it will be, but the smaller pellet density and quality is. On the contrary, if the compression ratio is too large, there will be blockage.
From years of practice, Richi Machinery find that for making animal feed pellets with the same specifications from the same material, the flat die is much thinner than ring die. Compared with ring die, good quality flat die pellet mill machine has the advantages of brief structure and compact size. It can be used both sides, so the production cost is saved for users, since the flat die is a main wearing part in flat die poultry feed pellet mill. The symmetry of flat die determines it can be used both sides.
The features of flat die pellet machine roller are that it has low rotating speed and large diameter. Its rotation speed is even less than a half of some models of ring die type animal feed pellet processing machine roller, while the large diameter can increase the grabbing angle of roller, which makes sure it has strong grabbing ability to raw materials, and decreases the possibility of slip. However, when in working, not the whole roller is revolving. Seen from its axial direction, both the inner and outer side of roller slide; such slide is determined by the working principle of small flat die pellet mill machine rather than material change.
Although the existence of slide can in some extent accelerate roller abrasion, but from objective perspective, the slide can increase the extruding performance of pelletizing machine for manufacturing feed pellet, which makes flat die pellet machine stand out in processing feed raw materials .
