Biomass energy raw materials, agricultural and forestry waste such as pruned tree branches, trunks, offcuts, straw, etc. are all waste generated every year. The previous treatment methods have always been incineration, piling up and natural weathering. In recent years, with the introduction of policies on waste utilization and new energy, biomass energy has been developing rapidly. This has also driven the rapid development of models mainly featuring Shandong vertical ring die biomass pellet machine, which have been widely applied in the market. This kind of granulator has the advantages of high output, strong adaptability to materials and low energy consumption.
If there is a large amount of granular powder during production, it will leave customers with the impression that the granular quality is poor. Today, TONY Biomass pellet machine manufacturer helps you analyze the reasons.
1.This situation is most likely to occur with newly purchased machine. There are problems with the usage process, which is a problem that many people tend to overlook.
If the usage process of the newly purchased equipment is neglected, it is very likely to cause the machine to jam and clog the holes as soon as it is turned on, and of course, powder will appear. Therefore, for the purchased pellet machine, it is necessary to take some wood chips that will be pressed into pellets and mix them with about 10% industrial oil, such as ordinary engine oil, to grind the mold of the pellet machine. This step is very crucial. Only the ground molds can produce beautiful and smooth particles. And as the mold is used for a longer time, the finished particles made will look better.
2. The moisture content of the raw materials is too low.
When making pellets, whether it's straw or wood raw materials, we have requirements for the moisture content of the raw materials. The prerequisite is that they should not be too wet; being too dry is also not acceptable. Take sawdust for example. The moisture content of sawdust is too low to be extruded into shape, and all that comes out is powder. Generally speaking, the ideal moisture content for granulation is 10% to 15%. The granulation effect is good within this humidity range. If the moisture content of the raw materials is too low, the solution is very simple: just spray some water and mix evenly.
3. Unreasonable operation.
The most common issue is the gap between the mold and the pressure wheel assembly. Without an appropriate gap, extrusion molding is impossible. This will lead to the situation where the raw materials come out exactly as they enter. Occasionally, there will be formed particles flowing out, accompanied by a large amount of powder.
4. The granulation system malfunctioned, which is not what we wanted but also a frequent mechanical failure.
Most malfunctions occur due to unclean materials containing hard objects, which can cause damage to the granulator. Additionally, problems with the bearings may also lead to this issue. It is also possible that the mold in the machine is damaged.
Through continuous improvement and innovation, the TONY brand biomass pellet machine can meet the processing requirements of different materials. It has expanded from the original single and common raw materials such as wood chips and straw to biomass waste such as sludge, medicinal residue, and domestic garbage. All of our TONY biomass pellet machine can be pressed into shape.
