View Full Version : Need Handle the Problem of Biomass Pellet Machine

Biomass pellets fuel energy refers to the cylinder sticks with 6-12mm diameter made by pellet mill from various kinds of biomasses. As a world leading pellet mill manufacturer, Henan Fote Heavy Machinery Co., Ltd. (http://www.paradisedivingasia.com/) has developed biomass pellet mills for sawdust, wood shaving, wood chips, alfalfa, straw, peanut shell, bagasse, bamboo, grass, rice husk, waste paper, etc. that can make best pellets fuel. There are reasons for the powdery material or basically no pellets but all powdery material in the pellet when compressed by the biomass pellet machine. They are compression ratio of mold and moisture content of material.
1. The compression ratio of the die
If the compression ration of the mold is improper, the machine can not give enough pressure to the straw material and time for formation. It leads to the material flowing out from the machine without compressing which causes the powdery of pellet.
2. Moisture content of raw material
Too large or too small of moisture content of raw material can cause the powdery situation. The pellet can not be formed with big size powdery material if moisture content is large. The pellet has much small fines if the moisture content is small. The most proper moisture content for compressing of pellet machine is about 15%. The specific moisture requirement should be on the basis of feedstock.
As for the above reasons, the method for solving is simple.
1. Take good control of moisture content of material. Add a drying process when the material has high moisture content.
2. The compression ratio of die can not be changed. The simple way is to change the die. Several types of die are suggested for testing for finding the best proper one.
3. Installment and testing of pellet mill. It is necessary to install and test the machine by the manufacture with active cooperation with the producer.
