The jaw crusher is divided into two types: coarse crushing and fine breaking. The main purpose is to coarsely break the raw materials and prepare for secondary crushing. Jaw crusher is suitable for crushing hard or medium hardness raw materials. It is not suitable for crushing soft and hard materials. The moisture content of materials should be no more than 10%. The moisture content of raw materials is too high. Breaking efficiency. It is particularly worth mentioning that the brick and tile factory should pay attention to two points when using the jaw crusher: First, before the material enters the crusher, the powder in the material should be sieved out in advance, which makes the utilization efficiency of the crusher capable. It is of great significance to see that these particles can fill the grooves between the ridges of the rafts, so that the effective height of the ribs is reduced, so that the material between the slabs is broken by pressure alone. Another point to note is that feeding the jaw crusher should ensure that the material is applied along the width of the entire feed port as much as possible to ensure uniform feeding and, if necessary, a special feeder. The hammer crusher is divided into vertical, horizontal, single rotor, double rotor and other types according to the structure type, and is mainly crushed by the impact, impact, shearing and grinding action of a high-speed moving hammer. Most of the discharges are provided with fixed rafts. Users can select the rafts with appropriate apertures to control the discharge size according to their needs. The crusher is suitable for crushing brittle materials, such as coal gangue and shale . It is not suitable for very hard materials or viscous materials. The crushing ratio of single rotor is generally 10-15, and that of double rotor is 20-30. The moisture content of the raw material is very strict, and generally should not exceed 8%. If the water content is too high, the pores of the slab are easily blocked without discharging. In order to prevent the use of non-broken material, such as iron pieces, nails, etc. fall into the crusher must be checked carefully added into the material and to ensure that the non-broken promptly removed. The impact crusher is a deformation of the hammer crusher. The main changes are: the movable hammer head is changed to a fixed hammer head; on the casing, one or two counterattack plates are mounted on the tangential direction of the rotor hammer head, and the impact crusher is There is no seesaw, so its discharge particle size is large, it is often used for coarse and medium crushing. It is suitable for medium hardness materials. In addition, the water content of the material can be relaxed to about 12%. The heavy hammer impact crusher combines the advantages of the impact crusher and the hammer crusher. It can crush all kinds of strong hardness, medium hardness and brittle ore, coarse and fine break, in the stone or sand production line. After one crushing, you can eliminate the need for other crushers, which is convenient, fast and time-saving. The cone crusher is divided into three types: coarse crushing cone crusher , medium crushing cone crusher and fine crushing cone crusher. The motor drives the moving cone to make the swinging motion, and sometimes it is close to the fixed cone, so as to do the pressing motion, mainly used in metallurgical industry, building materials, road building industry, chemical industry and silicate industry for crushing medium and medium hardness of various ores and rocks. For the roller crusher (double roll crusher), the double roll crusher utilizes two sets of individually driven roller shafts, and the surface of the roller can be toothed, which is called a toothed roller crusher. The crushing force and the shearing force generated by the relative rotation break the material. When the material enters the crushing chamber of the machine, the material is subjected to the force of the rotating roller shaft, so that the material is forced to pass between the two rollers while being squeezed by the roller shaft. After rolling and shearing, the material begins to break. The small particles after the crushing are traversed along the rotation of the roller, and are thrown to the bottom of the machine through the gap between the two rollers. The large granular material exceeding the gap continues to be broken into small particles. . Mainly crushing ore below medium hardness. The center of the composite crusher is an upright hammer crusher rotor, and the outer ring (the inner layer of the outer casing) surrounds the arc counter-plate. The material enters the inside and is hit by the hammer on the rotor to the counter-piercing plate. If the material is the right size, it will fall below, otherwise it will be broken on it. Small crushing is possible. The impact crusher is also called the sand making machine. The working principle of the impact crusher is to let the stone collide with the stones that are accelerated by the impeller during the natural falling process to achieve the crushing.
