Pellet machine can be classified into flat die pellet machine and ring die pellet machine. Flat die pellet machine has the convenient and simple structure, adjustable pressure, and application for all different material. Ring die pellet machine, in the suppression of feed, especially in terms of concentrate feed is indeed a good move, its large output, low power consumption, which is the flat die pellet machine can not match.
The flat die pellet machine and ring die pellet machine have different working principles.
Flat die pellet machine is based on the mechanical circular motion, the motor (or diesel) powered, driven gear (or pulley) passed to the spindle, and the flat die, in the friction force of the roller rotation, Under the extrusion of pressure wheel out from the die, through the cutter can be adjusted to give the desired particle length, and then the rejection trays made of particles through the spout sent outside the machine. About the ring die pellet machine,material through the inlet of the material into the rotating bowl, due to the centrifugal force, the material continuously thrown to the inner wall surface of the die, to form a uniform annular material layer. The material layer is brought into the annular die and wheel contact surface, after strong compression molding and rollers, cylindrical extruded from the die hole, and fixed on the casing cover cutting a length uniform pellets.
Here let’s know something about straw pellet machine.
Straw pellet machine is making use of crop straw fuel corn stalks, wheat straw, rice straw, peanut shells, corn cobs, cotton stalks, soybean rod, weeds, twigs, leaves, sawdust, bark and other solid waste as raw material. After crushing , pressuring, increasing the frequency, it can be formed into a small rod of solid particulate fuel. The density of raw material is generally about 130kg/m3, and molded particle density is greater than 1100kg/m3. The transportation and storage is extremely convenient, while its combustion performance is greatly improved .
The working process of is raw materials collected, then crushing to mechanical granulating molding, and finally bagging sales according to different crop harvest. At the same time, mass storage of raw materials should be promptly followed by grinding, molding. Be careful not to immediately bag molding, the principle of thermal expansion and contraction to be cooled for 40 minutes, and then bagging transport.
The molding fuel characteristics of straw pellet machine is heavy, small size, resistance to burn, easy storage and transport. The volume of molding material is 1/30 of the volume of raw material. Proportion is 10 to 15 times than the raw material (density of 0.8-1.4). Calorific value is up to 3400 to 6000 kcal, which is a high volatile phenol solid fuel.
The fuel uses of straw pellet machine is that the forming straw fuel pellet fuel is a new type of bio-energy, which can replace wood, coal, fuel oil, liquefied petroleum gas, widely used for heating, living stoves, hot water boilers, industrial boilers biomass power plants.
The use of pellet fuel can be divided into there types. The first is high fuel efficiency and easy storing raw material for domestic heating and life energy. The second is that it can be regard as primary fuel for industrial boilers, which can replace coal and solve environmental pollution. The last one is that it can be used as fuel thermal power for generation.
Flat die pellet machine can be widely used in animal husbandry and aquaculture, medium and small farming plant, feed mill and brewing, sugar, paper, pharmaceutical, tobacco factory and other industries organic waste re-granulation. Flat die pellet machine is a small farming enterprises particle production and processing of organic fertilizer preferred equipment manufacturing enterprises. Ring die pellet machine,which is belonging to feed pelleting equipment, is based on corn, soybean meal, straw, grass, rice husk and other direct repression particles pulverized feed processing machinery, widely be used in large, medium and small-scale aquaculture, grain feed mills , livestock farms, poultry farms, individual farmers and small and medium farms, farmers or large, medium and small feed mills use.
According to the above, we can know the advantage and application of pellet machine. From the perspective of environment protection, we can regard it as the better choice to deal with the agriculture waste.
