How to Control Pellet Size Processed by Wood Hammer Mill?

As we all know, wood hammer mill can process a lot of materials, such as waste wood, scrap materials, furniture factory waste wood, waste wood doors and windows, bamboo, straw, corn cob, plant roots etc. The size of wood pellets produced by the same type of wood hammer mill will be different, as these machines are produced by different manufacturers. Each user has a requirement for particle size of sawdust when select the wood hammer mill, customers are more concerned about that whether the effect of wood hammer mill can meet their own requirements or not, and how to adjust the machine so that the material can be processed more evenly?

Three methods to control the sawdust size produced by wood hammer mill?

• As we all know, the key factor affecting the particle size is the diameter size of the sieve on the wood hammer mill, which is almost the most common factor for wood hammer mill users, and it is very easy to solve, as we can customized the sieve with matched hole diameters.
• If you have already bought wood hammer mill and sieve, you can adjust the speed of the wood hammer mill to control the discharged particle size. If the wood hammer mill has a high rotating speed, the sawdust particles must be the finest, if the speed is low, the particles may be a bit rough.
• The size of discharging granules can also be controlled by adjusting the quantity of the inside rejection of wood hammer mill. The more the quality of rejection of wood hammer mill is, the more fine the sawdust powder is.

How to solve the problem of oversize pellet produced by wood hammer mill?

• First of all, adjust the gap of the wood hammer mill knife or replace the screen and hammer, and adjust the position of the feed liner, so that the gap between the lining plate on both sides and the knife is uniform. If the lining of the inlet is worn away, replace it.
• What should we do if there is a knock in the wood hammer mill during the operation? This is still using the exclusion method, stop the wood hammer mill operation and clean the crushing chamber, or check the tightening of the lining plate and the gap between the hammer and the housing, replace the broken parts.
• In the operation of wood hammer mill, the bearing temperature is too high, we should immediately check the wood hammer mill. If the cause is uncertain, the elimination method can be used: Check whether the grease is adequate, the normal grease should be full of 50 % of the bearing seat volume; check the cleaning bearings and replace the grease; Or replace the bearings directly.

How to control the processed particles are very uniform from wood hammer mill?

The wood particle size produced by wood hammer mill can be controlled by adjustment, after controlling, the quality of finished wood particles can be improved. If you want to control the size of the processed particles are very uniform, the following two ways may be useful.

• For general wood hammer mill, there are two kinds of knife tools in the machine, one is an alloy blade, which is used to make round logs or lumber into small pieces, rotate at high speed through the rear flap, process those materials into granules instantaneously. The inside of the wood hammer mill has a sieve with regular mesh, after breaking, these wood particles left outside the machine through the mesh. This is the initial processing of materials, the size of the particles vary, if it wants to be very uniform, add a sieve.
• Sift the processed wood shavings through a linear sieve, by screening the vibrating screen with different sieve holes, the size of the particles can be controlled very strictly, and the efficiency is also high.

Generally, these two methods can well control the size of the particles processed by wood hammer mill.
