Biomass densification is the bonding together of waste biomass product, such as wood chips or sawdust, peanut husk, rice husk, sunflower seed husks, bagasse (sugar cane or sugar beet residue), coffee shells, coconut husks, etc. The bonding is achieved by the pressure and heat of the biomass briquette machine utilizing the natural resins in the biomass waste product.

The guiding principle behind the production of biomass briquette machine is that natural biomass material is essentially a waste material, i.e. the natural by-product of, for example, the timber industry: chippings, sawdust, offcuts, slabwood, etc or agricultural products: sunflowers, rice, peanuts, etc. The material is prepared for the biomass briquette machine by chipping or milling and drying before being fed into individual biomass press.

In the production process at no time are any additives, chemicals or foreign bodies introduced. The biomass briquette is a natural wood or biomass product. As a result of the materials preparation and the heat and pressure used in production, the briquette is dense and dose not expands at all when burning and has very low ash content.

In order to make the machine in good condition, the biomass briquette machine should be maintained regularly. There are several points that we should pay attention to during production.
Check up the electrical components in the electricity cabinet is well-connected, sensitive and reliable or not, to protect it from moisture and dust and to keep the cabinet clean. The biomass briquette machine should be maintained regularly according to the service condition. Examine the wearing condition of each part and the quick wearing parts should be repaired or replaced of. The bearing of each part should be cleaned and maintained regularly.  

Add lubricating oil to each bearing for the quick wearing of the roller and main bearing due to the lack of oil. The main bearing of biomass briquette machine should be added with grease every half a month, and the bearing of compression roller should added with oil every day. Each of the rotating part should have enough lubricant oil.

The compression roller and the flat die are the main spare parts of the biomass briquette machine, and it is necessary to check up the clearance of the compression roller and the flat die are proper or not, the position is right or wrong, the fastening screws are tight or not, the lubricant oil is enough or not to ensure the normal operation of the biomass briquette machine. In order to prolong the service life of mold of biomass briquette machine, the die should be notices regularly, especially keeping the clearness of the inside of ring die. Don’t use the hammer to unpack the machine to avoid of damage to the smoothness of machine’s outer surface. If the hard things like the metal scraps and stones enter into the chamber of machine, it is necessary to remove the hard things to avoid of damage to the roller and die.

When the production is finished, it is necessary to compress the material with high moisture content to stuff the die to ensure the discharging next time. The fastening parts and the lubricant should be examined every day after finished the whole day’s work.
