First, let’s look at the horizontal ring-die pellet machine, which is the earliest model on the market. Is the horizontal ring die pellet machine suitable for biomass materials? The first characteristic of biomass materials is that the specific gravity of the materials is relatively light, and lighter materials are more difficult to press and form. This is a common characteristic of biomass materials. When there was no vertical ring die pellet machine on the market, we had been trying to use the horizontal ring die to press biomass materials. First of all, there is a bottleneck when biomass materials are fed into the horizontal ring die. That is, if the feed port wants to send the materials into the pressing cavity, it needs to be fed from the side, which will inevitably lead to unsmooth feeding of the materials, because the biomass materials are lighter. The fluidity is not good and the material is relatively fluffy. When feeding from the side, it is easy for the material to expand and block here, causing the material to get stuck and unable to be discharged. Even if the material enters the pressing cavity, the pressed roller does not rotate, but the mold disc rotates. The specific gravity of the material is too light, the friction is not enough, and the material on it cannot be carried. The two wheels will eat the material unevenly, causing a secondary impact on the pellets. , which results in poor molding of the pellets.In addition, there is another drawback to the horizontal ring die for making biomass pellets, which is the reducer. Horizontal ring die pellet machine, the reducer uses the differential of the rear axle of the car, which is characterized by small speed ratio, high speed and small torque. Biomass materials require a relatively large compression ratio, relatively large torque, and relatively slow speed. Therefore, the conditions for making biomass materials are not met.
