2. According to the way of crushing force, crushers can be roughly divided into two categories: (1) crushers: crushers generally deal with large pieces of materials, and the proct size is coarse, usually greater than 8 mm. Its structural feature is that there is a certain gap between the broken parts and they do not contact each other. Crusher can be divided into coarse crusher, medium crusher and fine crusher
(2) grinding machine: Generally speaking, the material processed by the grinding machine is fine, and the proct size is fine, up to 0.074 mm, even finer. Its structural feature is that the crushing parts (or medium) contact each other, and the medium used is steel ball, steel bar, gravel or ore block. But some machines have the function of crushing and grinding at the same time, such as autogenous mill. According to the crushing mode and mechanical structure characteristics (working principle), the crushers can be divided into six categories:
(1) jaw crusher (tiger mouth): the crushing action is to press the movable jaw plate to the fixed jaw plate periodically to crush the ore block in it
(2) cone crusher: the ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block< (3) impact crusher: it uses the high speed impact of the plate hammer and the rebound effect of the impact plate to make the material receive repeated impact and crush. The plate hammer is fixed on the high-speed rotating rotor, and several impact plates are arranged at different angles along the crushing chamber
(4) roller crusher: in the gap between two opposite rotating round rollers, the ore block is mainly crushed continuously, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting
(5) impact crusher: the ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher
(6) grinding machine: the ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder
(7) other types of crushing mills: A. roller mills: grind materials by rotating rollers. B. Disc mill: the disc rotation of vertical axis or horizontal axis is used as crushing part. C. Centrifugal mill. High speed rotating parts and medium are used to proce centrifugal force to complete crushing. D. Vibration mill. High frequency vibration is proced by the rotating shaft, which makes the medium and material collide with each other to complete the crushing effect
in order to check and understand whether the technical operation of each proction link meets the process requirements; In order to provide the managers and technicians of the concentrator with the weak links in proction, find and solve the problems in time, and promote the normal proction, the technical detection plays an indispensable and decisive role. It is an important means to do well in proction technology management, metal balance and management level. Therefore, each concentrator must carry out a series of proction technology testing work, and set up corresponding organizations according to the specific situation, such as quality management materials, technical inspection department, technical supervision station, testing group, etc From: Henan Zhenping Xinlong Machinery Manufacturing Co., Ltd.)

4. In the process of ore crushing, according to the operation mode and the particle size of crushing procts, crushing equipment can be roughly divided into crusher and grinding machine
the crusher is used in the coarse crushing stage. Generally, the feed particle size is larger, and the proct particle size is also larger, usually more than 6 mm (- 6 mm accounts for less than 60%). Their basic feature is that the working parts do not contact each other and keep a certain gap. According to the crushing mode and principle, it can be roughly divided into the following four types:
(1) jaw crusher (also known as Laohukou), which is an old and widely used crushing equipment. The crushing action is that the moving jaw periodically approaches and leaves the fixed jaw. Crushing the ore block between the two jaw plates (mainly crushing) and discharging (falling by self weight) is intermittent crushing. According to the movement characteristics of moving jaw, jaw crusher can be divided into simple swing (double toggle plate) and compound swing (single toggle plate)
(2) cone crusher is a continuous crushing equipment. According to the feed and proct size, cone crusher is divided into circular cone crusher and medium and fine cone crusher. According to the length of the parallel belt B (the gap between the moving cone and the fixed cone) of the crushing chamber, it can be divided into standard type, intermediate type and short head type cone crushers
both rotary cone crusher and jaw crusher belong to coarse crushing equipment, but because the cone crusher works continuously, its proction capacity is much larger than jaw crusher when the feeding properties are the same. The standard type and the short head type are used for medium crushing and fine crushing equipment respectively, while the intermediate type is between the two. Generally, it is used as the second crushing equipment when two-stage crushing
(3) impact crusher, which uses the "free" crushing principle of impact force to crush ore, the ore is crushed in the crusher by the impact of impact plate (plate hammer) and impact plate, and the complex effect of multiple collisions between ore. Therefore, the crusher has the advantages of large crushing ratio, high efficiency and less over crushing. It is a promising crushing equipment
(4) roller crusher. The ore is fed into two opposite rotating round rollers (smooth or non smooth) from the upper part. It is drawn into the crushing chamber by the friction between the material and the roller surface and crushed by the roller. The crushed ore is discharged from the gap between the two rollers by gravity. It is mainly used for medium and fine crushing of medium hard and brittle materials.

5. It can be divided into six categories according to the crushing mode and the structural characteristics of machinery (action principle)< (1) jaw crusher (tiger mouth). The crushing action is that the movable jaw plate periodically presses the fixed jaw plate to crush the ore block sandwiched in it< (2) cone crusher. The ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block< (3) roller crusher. In the gap between two opposite rotating round rollers, the ore block is mainly crushed continuously, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting< (4) impact crusher. The ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher< (5) grinding machine. The ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder
