Overview of Powder Grinder Machine
A. Introduction to Powder Grinder Machine
As a professional wood processing machinery, the wood powder machine is of durable design and high yield characteristics. The wood powder machine is equipped with powder fineness analysis equipment which can control the fineness of the material intact, improving the sieve thought rate, the machine inlet is of feedstock self-suction design, preventing the machine from damage by metal. The whole machine body is cooled by water; there are stator cutter blades, rotating cutter blades, and crushing cutter blades in the grinding chamber. The machine body is made from new material which makes the wood powder machine feature low noise, no vibration, and less dust.

How to Dispose Machines in Wood Powder Production Line
In wood powder production, a single wood powder machine is far less than needed. Usually, we have to choose other machines for wood powder pre-treatment and after-treatment. Here Amisy will share some knowledge about wood powder machines’ disposition in industrial production.

wood powder plant1. Raw material processing
Please be aware of your raw material for wood powder production. If your wood particles are too large. Please choose crushing machines or grinders to break down. The max size of wood particles to be processed in our wood powder machine is 40-60 mm. That’s to say, wood sawdust or wood chips larger than 60 mm need to be crushed in small sizes.

Here for wood crushing machines, there are wood crushers, wood hammer mills, and wood chipper shredders. An example of a tree branch of 200 mm diameter should be crushed by wood crushed into 3-5 mm, 6 mesh to 4 mesh (the larger the number, the smaller the wood particles). Wood hammer mill is also a kind of crushing machine, which can break large wood branches to 2-8 mm thickness wood sawdust. While wood chipper shredder is mainly used for wood chip production and if the chips are used to be processed into wood pellets or wood powder, they still need grinding.

2. Moisture control
Only raw materials of consistent quality can produce consistent-quality pellets. So as the wood powder. Wet wood particles are easy to adhere to the inner wall of the wood powder machine and will slow down the working efficiency. A necessary drying device is needed to reduce wood particles’ moisture in order to make high-quality wood powder and ensure a high yield.

Wood sawdust dryer can reduce moisture content by 10%-20%. Hot air boilers can be added for a better drying effect if the raw material is too wet. For biomass material whose moisture content is less than 35%, we recommend the one boiler pipe dryer as it can eliminate more than 20% moisture content; but for those containing 35%-50% moisture content material, the two boilers pipe dryer is necessary because its powerful drying effect.

3. Wood powder fineness
Wood powder in 3-5 mm can be suitable for wood pellets production. Generally, powder in 200 mesh has already met all demands in wood powder deep processing. Wood powders are always in 60-80 mesh in paper-making production and powder in 120 mesh can be used for upscale incense production.

The wood powder machines can offer fineness from 10-500 mesh.
