Factors affecting the life of biomass pellet machine
Nov 09, 2018

Biomass granulator is a kind of granular fuel made from crop straw or sawdust and pressed by biomass granulator. What factors affect the life of biomass granulator are introduced here.

1. The water content of the material is too low, the hardness of the processed product is too strong, and the power consumption of the equipment is too large, which increases the production cost of the enterprise and reduces the service life of the biomass granulator. Excessive moisture is not easy to crush, which increases the number of hammer impact. At the same time, because of friction of materials and hammer strike, heat is generated, which evaporates the water inside the processed products. Evaporated water and crushed fine powder form a paste and block the sieve hole, reducing the discharge of biomass granulator. Generally, the raw materials of products such as grains, grains, etc. The moisture content of crushed products such as corn stalks was below 14%.

2. At the end of material crushing, mix a little wheat husk with edible oil and put it into the machine, press for 1-2 minutes, then stop the machine, so that the hole of the mould of the biomass granulator is filled with oil, so that it can be put into production next time, which not only maintains the mould, but also saves man-hour. After the biomass pellet machine is stopped, loosen the wheel adjusting screw and remove the residual material.

3. Permanent magnet barrel or iron remover can be installed at the inlet and outlet of biomass granulator to avoid affecting the service life of press wheel, die and center shaft. The temperature of pellet fuel in extrusion process is as high as 50-85 C, and the pressure wheel bears strong passive force while running, but it lacks necessary and effective dust protection device. Therefore, bearings must be cleaned once every 2-5 working days and high temperature resistant grease must be added. The spindle of the biomass granulator is cleaned and refueled every other month. The gearbox is cleaned and maintained every six months. The screw tightening and replacement of the transmission part should be carried out at any time.
