Process of flat die wood pellet machine

 Biomass fuel granulation process. The basic process steps of biomass granulation are roughly similar. However, due to the different physical properties of the raw materials and the different working principles of the forming wood pellet machine, the specific process is still different. The key process steps of the flat die machine are specific. The introduction is as follows:

In the crushing process, when the flat mold is used for granulation, the smaller the particle size of the raw material, the easier it is for the particles to fill and fit each other. Therefore, the average energy consumption per unit output of the granulator is smaller. The wear speed is also slower, and the water permeability and hardness of the particles are higher. However, blindly pursuing the reduction of particle size will cause the energy consumption of the crushing process to rise sharply. Therefore, it should meet the processing requirements of flat die granulators under the premise of, make the particle size as large as possible. In fact, it is one of the advantages of the flat die wood pellet maker to be able to suppress large-size raw materials. Generally, for crop straw and other raw materials, the maximum particle size is required to be less than 2×2×30mm, while for wood raw materials, the requirements are more stringent.

In the granulation process, the dried material enters the granulation process and can be processed directly without quenching and tempering. Conditional manufacturers can choose automatic control system and die roll automatic gap adjustment device. The automatic control system adjusts the frequency converter of the feeding motor according to the change of the host current, so as to adjust the feeding amount in real time, which can effectively avoid the occurrence of machine blockage. The die roll automatic gap adjustment device can collect die roll gap data, and control the hydraulic system through feedback and comparison, so that the gap is consistent with the set value, and can be changed at any time during the production process. Generally speaking, the grinding roller gap should be as small as possible during the starting phase, which can reduce the starting torque and reduce the motor load. After entering the steady state work, the grinding roller gap should be slightly larger, which can increase the compression stroke and obtain hard and smooth particles. The setting of the gap change with time can be input into the control system. After starting, the machine can automatically adjust the die roll gap. Pressure rollers and flat molds are easy to wear parts and need to be replaced regularly. The service life of pressure rollers can be slightly longer, but it is best to replace the flat molds together. Generally, flat molds can work for 800-2000 hours, depending on the material and processing technology of the parts. According to the test results, the PM60 flat die pelletizer is suitable for processing biomass materials such as sawdust, sawdust and straw mixture, with a molding rate of over 93%, power consumption per ton under 55 kWh, and an hourly production capacity of about 800kg-900kg.
