The size reduction of wood is an energy-intensive process. Due to the viscoelastic nature of wood, the breakage of particles needs a lot of energy. Industrially, the grinding of wood and other lignocellulosic materials has mainly been performed with a hammer mill, knife mill and disc (attrition) mill.
A disc mill is used to pulverize solid materials. The material is placed between two discs, one of which rotates. Sorting is automatic, producing particles of uniform size. Disc mills often are used to pulverize ceramics, ore and construction materials. Disc mills can have a vibrating feature.
Size ReductionA major step in the polymer development procedure occurs when the individual resin pellets are ground to a fine powder. For that reason, the choice of polymer grinding techniques becomes a vital component of the overall process.At General Polymer Services, we offer a wide array of grinding equipment, as well as professional advice on…

Cryogenic Grinding cryogenic grinding process starts with air-dried herbs, rather than freeze-dried herbs. Solid materials are ground or pulverized by way of hammer mills, attrition mills, granulators or other equipment. A smaller particle size is usually needed to enhance the further processing of the solid, as in mixing with other materials. A finer particle also helps in melting of rubber ...

Cryogenic grinding is the act of cooling or chilling a material and then reducing it into a small particle size. Cryogenic grinding technology can efficiently grind most tough materials and can also facilitate cryogenic recycling of tough composite materials and multi component scrap. The term "cryogenics" originates from Greek word which means creation or production by means of cold.
