New ore crusher and its main types

Although there are many types of crushing machine, but according to the different methods of force, the material crushing, extrusion, bending, impact, shear and Raymond Mill. In the crushing machine, the force situation is very complex, often there are several forces exist, of course, there is only one or two major forces in a broken machine. Because the shape of the material particle is irregular, and the material property of the material is different, the grinding method is also different: 1 the material is placed between the two working faces, and the material is crushed by the compressive stress when the pressure is applied. 2 the material will be placed in a plane and a working surface with a sharp edge. When the working surface with a sharp edge is extruded from the material, the material will be split along the direction of the pressure line. The reason is that the tensile stress on the splitting plane reaches or exceeds the tensile strength limit of the material. The tensile strength of material is much smaller than that of compressive strength 70 percent off broken material is subjected to bending stress. Two point supported simply supported beam or multi support beam subjected to concentrated load. When the bending stress of the material reaches the bending strength of the material, it is broken and broken. 4 impact crushing material by the impact force and broken, because of its crushing force is instantaneous action, the crushing efficiency is high, Impact Crusher, energy consumption is less, the impact of the following are broken: (1) the impact of moving objects on materials (2) the impact of high speed moving materials to fixed working face (3) the impact of high-speed movement of materials (4) the high speed moving body impacts the suspended material 5 grinding (grinding) Under certain pressure and shear forces between surfaces of material and motion, shear strength limit of the shear stress to the material, the material is crushed, or between each other, when the shear friction material and the material crushing grinding effect. Main types of crushing machinery 1 according to the structure and the working principle of the different commonly used crusher has the following types (1) Jaw crusher is to rely on the movable jaw plate for periodic reciprocating movement, the material into the two jaw plate crushed. (2) the impact of the hammer crusher Material by the high-speed rotation of the hammer and the material itself to the impact of the high speed of the impact of the fixed liner. (3) the eccentric rotation of the cone crusher (gyratory crusher) is caused by the eccentric rotation of the inner cone so that the material between the two cones is bent and crushed (4) the impact of the crusher Material by the high-speed movement of the hammer hit, so that the impact of the material to the high-speed impact plate, as well as the collision between the material and broken. (5) the material of the roller crusher falls on the rollers which are parallel to each other and opposite to each other (opposite direction), and the material is pulled into the rotary roller under the action of the friction force of the roller surface, and is crushed by the extrusion of the roller.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands
