Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of the pulverizer, and particularly relates to a pulverizer with feeding and discharging functions. BACKGROUND
[0002] The pulverizer is composed of coarse crushing, fine crushing, air conveying and dust removing devices, and achieves the purpose of pulverization through high-speed impact, shearing or grinding, and utilizes wind energy to form powder at one time, and cancels the traditional post-screening procedure, and the pulverizer can be classified according to different standards, for example, according to the size of the crushed material, the pulverizer can be classified into a coarse crusher, a pulverizer and an ultrafine pulverizer, according to the D90 standard (90% of the material reaches the predetermined fineness) of the required material fineness, the pulverizer can be classified into a crusher (below 60 mesh), a pulverizer (60-120 mesh), an ultrafine pulverizer (120-300 mesh) and an ultrafine pulverizer (above 300 mesh), and according to the application field, the pulverizer can be classified into a large-scale pulverizer and a small-scale pulverizer, the large-scale pulverizer is mainly suitable for the metallurgical, building material, chemical and mining industries, and the small-scale pulverizer is mainly suitable for the food, chemical and pharmaceutical industries, and according to the mechanical principle, the pulverizer can be classified into a mechanical pulverizer, an air flow pulverizer, a grinding machine and a low-temperature pulverizer, and the mechanical pulverizer can be further classified into a tooth type, a hammer type, a knife type, a turbine type, a pressure grinding type and a milling type pulverizer.
[0003] Material characteristics: when the material contains a lot of sticky components or moisture, these components are easy to adhere to the screening net, resulting in reduced screening efficiency, uneven particle size distribution or a large number of fine particles, which increases the difficulty of screening, so that the screening net cannot effectively separate the raw materials that do not meet the size, screening net design problem: the size, shape and arrangement of the screening net hole diameter design factors will directly affect the screening efficiency, if the hole diameter is too large or too small, or the shape is not suitable, it may lead to poor screening effect, the material and wear resistance of the screening net will also affect its service life and screening efficiency, the screening net with poor wear resistance is easy to wear, which leads to the increase of the hole diameter, reduces the screening precision, and also causes the automatic discharging to be unable to be realized, and manual intervention is required, material accumulation: when the material on the screening net accumulates too much, the screen hole is blocked, which reduces the screening efficiency, which may be caused by the reasons such as too fast material conveying speed, insufficient screening net area or poor discharging mechanism, screening net wear: the screening net will gradually wear during use, which leads to the increase of the hole diameter or the change of the shape, which not only reduces the screening precision, but also easily causes the material to be stuck in the screen hole, causing blockage, material property change: some materials may change during the pulverization process, such as increased moisture content and increased viscosity, these changes will increase the adhesion of the material on the screening net, thereby more easily causing blockage.
