Factors Affecting The Life Of Biomass Pelletizers
Apr 18, 2018

Biomass straw pellets or sawdust as raw  materials are pelletized ,Here, We introduced the factors that affect the life of biomass pelletizers:

The moisture of the material is too low, the hardness of the processed  product is too strong, the power consumption of the equipment during  processing is large, the production cost of the enterprise is increased,  and the service life of the biomass pellet machine is reduced.

Excessive  moisture is not easy to crush, increasing the number of impacts of the  hammer. At the same time, heat is generated due to the friction of the  material and the blow of the hammer, so that the moisture inside the  processed product evaporates. The evaporated moisture forms a paste with  the crushed fine powder and blocks the screen. Holes reduce the size of the biomass pelletizer. Generally, the moisture content of the crushed products of raw  materials such as cereals, corn stalks, etc. is controlled to be below  14%.

When  the material comminution is about to end, a little wheat husk is mixed  with edible oil and put into the machine. After pressing for 1-2  minutes, the mold hole in the biomass pellet machine is filled with oil  so that the next time the machine can be started, it can be fed and  produced. Maintain molds and save man hours. After the biomass pelletizer shuts down, loosen the pressure roller adjustment screw and remove the residual material.

A  permanent magnetic cylinder or iron remover can be installed at the  inlet of the pellet machine so as not to affect the service  life of the pressure roller, the mold and the central shaft. The  temperature of the pellet fuel during the extrusion process is as high  as 50-85°C, and the press wheel is subjected to strong power during  operation, but it lacks the necessary and effective dust protection  device, so every 2-5 working days, The bearings must be cleaned and high-temperature grease added. The  main shaft of the biomass particle machine is cleaned and refueled  every other month. The gear box must be cleaned and maintained at  intervals of six months. The screw fastening of the transmission part  should be replaced at any time.
