Biomass pellet plant is a kind of waste utilization and environmental protection equipment. The main agricultural residues and most forestry residues can be used as good raw materials for biomass pellets fuel, and have great energy utilization potential. Develop and improve biomass fuel technology and briquette fuel combustion technology to provide more incentives and support policies for briquette fuel. The establishment of more demonstration bases for biomass briquettes, the improvement of public awareness of environmental protection and the restriction of unreasonable use of coal will be conducive to the development of biomass briquettes, which has a great market prospect.

The complete set of equipment processing production line for biomass pellets is designed to densify and form biomass particles by drying, crushing, pressurizing, cooling, packaging and a series of processes of 2-3cm thick broken corn straw powder containing water. The formed biomass straw particles are small in volume, large in proportion, combustion resistant, easy to store and transport, and are mainly used for biomass power plants, biomass heating, and biomass boilers as fuel.

According to the material characteristics and project requirements, as well as the current global environmental protection requirements, our company specially designed this biomass pellet production line, including drying, crushing, granulating, cooling, packaging and other processes.

  1. Drying process

The materials entering this process are required to be 2-3 cm long raw material powder after coarse crushing, with moisture content below 40%. In this process, a drum dryer is selected to dry the materials. After the material is fed into the cylinder from the feed inlet, it is pushed to the lifting plate by the guide screw. Due to the rotation of the cylinder, materials are lifted and scattered by the lifting plate. At the same time, make longitudinal movement in the cylinder. The induced draft device introduces the hot air from the hot air stove or other heat sources into the dryer. The heat exchange between the material and the high-temperature medium makes the water contained in the material be heated and evaporated, so that it can be dried. The final material is discharged from the discharge port, and the residual air is discharged after dust is separated by the cyclone dust remover.

  • Crushing Process

The main machine of this process is an efficient crusher. The operating door is equipped with a safety interlock device to ensure safe operation. The feed inlet is on the top of the crusher and can be matched with various feeding mechanisms.

The materials enter from the top feed inlet through the conveyor and enter the crushing chamber through the feed guide plate. Under the impact of high-speed rotating hammer and the friction of sieve plate, materials are gradually crushed. Under the action of centrifugal force and air flow, the crushed material passes through the screen hole and is sucked out by the wind from the hopper below the base.

  • Granulation process

This process uses our MZLH series biomass pellet mill. Gear transmission system is adopted, with ideal transmission ratio, large driving torque and stable transmission; There are ring dies of various diameters and thicknesses, which can be selected by users according to different needs to obtain better technical and economic benefits. Variable frequency motor is used for feeding, and overload protection device is equipped.

  • Cooling process

The main machine of this process adopts our SKLN series counterflow cooling machine. This cooler is a new generation of cooling equipment successfully developed by our company based on years of mechanical production experience and current international cooling technology. This equipment is mainly used for cooling high temperature particles after granulation, so that the pellet feed with a temperature of 80-90 ℃ and a moisture content of 17-18% from the granulator can be cooled to a temperature slightly higher than the room temperature, and the moisture content can be reduced to 12-13%, which is convenient for transportation, storage and storage.

The machine has a unique cooling mechanism. The cooling air and particles move in reverse, so that the materials are gradually cooled from bottom to top, avoiding particle surface cracking caused by sudden cooling of general coolers.

biomass pellet plant

The new biomass pellet plant is a good equipment specialized in producing granular fuel. Some people would ask: is there any future in investing in biomass pellet plant? Does the processed product sell well? Can I make money?

From the policy point of view, the global efforts to control haze and air pollution in recent years are obvious to all. However, I believe that in the near future, it will expand slowly. It can be said that this is a trend. At the same time, the world strongly advocates the use of biomass energy instead of coal. The complete set of biomass particle production equipment is a special equipment specialized in producing and processing biomass fuel particles, and the demand market is growing.
