Biomass Pellet Production Machine

The compression ratio of the biomass pellet machine is determined by the raw materials. Let's take a few simple woods as an example. The compression ratio of poplar is 1:6, the compression ratio of pine is 1:7, the compression ratio of hardwood is 1:5, the compression ratio of debris is 1:5 5, and the compression ratio of corn stalks is 1:6.5.
From these simple numbers, the compression ratio of different raw materials is different. The harder the raw material, the smaller the compression ratio. The more fluffy the raw material, the greater the compression ratio, that is, the fluffier the raw material, the easier it is to press and shape, and the fluffier it is.

The heating temperature of biomass during molding shall not be lower than its softening point. The heating temperature not only affects the molding properties of the raw materials, but also affects the working efficiency of the biomass pellet machine. The heating temperature should be adjusted to a suitable range. If the temperature is too low, not only the raw materials cannot be molded, but also the power consumption increases. When the temperature increases, the power consumption of the motor decreases, but the molding pressure decreases and the molded product is squeezed. At the same time, the density decreases, it is easy to break and damage, and the surface of the pellets is overheated and burnt, and the smoke is large. Although the biomass pellet machine does not have external heating, the friction between the fuel and the machine parts can also heat the temperature of the raw materials to 140 degrees during the molding process, which can also soften the lignin contained in the raw materials and act as an adhesive, and finally cool and mold.
