Pellet Mill

The new vertical centrifugal pellet machine is the latest pellet machine in China. The pellet machine adopts a large modulus hard toothed helical gearbox, strengthened spindle, strong power output, equipment stable operation, low failure rate, low production cost. LD is the preferred machine model in the biomass industry. The equipment is applied to the materials with low adhesiveness and low shaping rate such as the rice husk, sunflower seed husk, peanut shell, and another fruit shell; branch, trunk, bark, and other wood waste; a variety of crop straws, rubber, cement, ash, and other chemical materials. This type of pellet mill is widely used in the biomass-energy fuels plant, power plant, wood processing plant, fertilizer plant, chemical plant etc. It is the ideal pressing shaping equipment with low investment and high profit.

Features

Pellet Mill Features

The gearbox adopts independent research and development big gear with 3 level drive. Module increased, gear strengths increased, carring more power and more stable, the service life increased 8-10 times than the traditional reducer, service life greatly increase.
Bearing room structure is smaller.

Make the whole structure compact; It guarantee the bearing room, pelleting room working steady. The hollow shaft connect directly with spline shaft in bearing room, guarantee high concentricity, reduce the failure rate of equipment.
Ring Die: High wear resistance and high capacity.

It adopt the stainless steel die which use integral carburation. Heat treatment hardness: HRC55-60. The die have a high abrasion performance, strong stability, whose using life is about 800-1000h. The enlarge design of discharge area increase the quantity of effective discharge hole, increasing the capacity, saving cost.
Oiling System

Reducer box and the main shaft bearing room adopt the circulating closed industrial gear oil lubrication, which makes the lubrication good effect and so that protect effectively the bearing life. The shaft bearing room is lubricated with gear oil, which greatly reduces the cost of traditional grease lubrication and improve work efficiency.

Working Principle

Vertical Ring Die Pellet Machine is a new biomass fuel production machinery by processing scrap from forest and agricultural waste like eucalyptus, pine, birch, poplar, fruit and agricultural straw, bamboo.

Compared with the old machine, it absorbed the essence of horizontal ring die and flat die pellet machine, solved the insufficient pressure, die crack problems of horizontal ring die pellet machine, and overcame the small capacity, high failure rate of flat die pellet machine.

The ring die pellet mills were designed at around the 1930’s based on the design of ring die. The basic pelleting principle of the ring die pellet mill is a simple operation where feed mass is distributed over the inner surface of a rotating, perforated die ahead of each roll, which compress the feed mass and compress it into the die holes to form pellets.
