The Introduction of the Hammer Mill
1.Hammer Mill is used for crushing small diameter raw materials, which are no more than 100mm such as corn straw,tree branches and so on. after crushing, the diameter ofthe final products could be 3-5mm
2.This hammer mill is mainly composed of casing, rotor, hammers and bars. The case is divided into two parts: up and down, which is connected by welding the cut steel; other parts are connected by screws. The one inside of case is high manganese steel lining board, which is easy to change when wore out.
3. In order to avoid clogging, humidity of crushed material should below 10%-50%.
the Hammer Mill is the most ideal milling equipment of all kinds of wood pieces, straw, grass, stalk, tree branches, waste cardboard, bamboo, wood scrap, corn stalk, peanut shell, wheat stalk, wood fuel, cotton stalk, biomass shell and so on, which can crush the raw material into small particles with size 3~5mm.
The machine includes airlock, blower, cyclone.It is equipped with high carbon steel blade and works with high efficiency and gains more good reputation from European users.
Hammer Mill Introduction
To reduce the size of wood chips and other suitably sized biomass raw materials to the correct particle size, a hammer mills is used. A hammer mill works on the principle of attrition. A rotating centre with a collection of flailing hammers impact at high speeds, shattering the material into particles. A screen with the desired particle size ensures the correct particle size is produced.
Post Particle Size Reduction and Cyclone Separation
Once particle size reduction has taken place, a fan is used to extract the particles from the based of the hammer mill. However the particles are now mixed in the air stream, and need to be separated. To separate the particles from the air stream, a cyclone separator is used.
The cyclone has a vertical position, and the air stream and particles are injected into the top of the cyclone. The gas stream, due to the shape of the cyclone is sent into a spiral. During the spiral action, the particles are separated from the air stream and leave the based of the cyclone. The separated air then leaves the cyclone through a central pipe through the top. The particles are now a suitable size for briquette or pellet compression, depending they have a suitable moisture content of around 12% for briquette compression, and 15% for the pellet mill.
