Use jaw crusher on the main raw material for rough break, in preparation for the secondary crusher. Jaw Crusher suitable for the material or broken hardware in the hardness of raw materials, not broken hardware and software of the raw material, the moisture content of the requested materials should be not more than 10 percent, the high moisture content of raw materials, Liu Bo Yi jaw board, impact crusher efficiency.

It is particularly worth mentioning is that the factory system in the use of jaw crusher attention should be paid to two issues: One is the material into the breakers, advance materials should be in the silt removed, the ability to Breakers use efficiency of view has great significance, because these can silt filling the jaw plate trough Prism, Prism highly effective reduction, jaw cubicles on the materials broken only by virtue of the pressure. It should also be noted that to the jaw crusher for materials should be as far as possible ensure feed along the entire width of the mouth to impose expected, the guarantee uniform feeding and, if necessary, use special feeding device.

     According to hammer crusher at a structural type of vertical, horizontal, single-rotor, dual-rotor, etc. Several types, most of the material with a fixed sieve, users can choose according to their own needs the appropriate aperture to control a sieve expected size. This type of crusher for crushing brittle materials, such as coal F-Shek, shale, very hard for the material or viscous material NA, the single-rotor broken than in the 10-15, double-rotor up to 20 a 30, its moisture content of the raw materials of very strict requirements, the general should not be more than eight per cent, if the moisture content of high-plugging sieve without discharging. In order to prevent the use of non-broken, such as iron, pin, and so fall into the crusher, which must be carefully examined the material and add ensure timely removal of non-broken off.

      Wind election hammer crusher in the hammer crusher on the basis of the installation of centrifugal blower (instead of the sieve plate of raw materials or sieve), elected by a small wind at the powder. It sets smash, upgrade (4 1 6 m), at a screening, with a multifunctional computer, and the advantages of simplified process for the natural moisture content of materials less than 6 percent of middle hardness of stone coal research, a better shale smash effect.

      Counterattack Breakers hammer crusher is the deformation of the main changes are: activities Hammerhead Hammerhead be fixed in the rotor chassis is on the tangent direction Hammerhead has a 1 1 2 counterattack plate; removed from the original the sieve plate. In the absence of a sieve plate, the expected size of its larger, commonly used in the rough broken and the broken, addition, the aircraft on the moisture content of raw materials can also be relaxed to about 12%

     Ball mill and various other Crusher comparison has the following advantages: ① structure simple; ② * to be more reliable, and occasionally there are also sets of metal security; ③ was grind materials mixing well; ④ can get the mill to be broken fineness; ⑤ can grind various hardness of materials. Ball mill shortcomings: ① power consumption; ② form factor, heavy body; ③ starting torque, big noise at work; ④ grind higher moisture content of the material, especially when the material is easy Turning materials lu attached to the ball mill, so moisture content of materials generally not more than 3% 0


     Cage Breakers - brick factory was widely used. Because cage Breakers high efficiency, broken after the materials powder particles (<= 0.2 mm) the ratio of high to brick molding. Maintenance than larger, but the cage breaking low failure rate, the moisture content of the raw material requirements of laxity, usually in the 12 percent within not affect fragmentation efficiency. Cage Breakers broken soft brittle material suitable, such as industrial slag, Bo dry soil, shale, in the hard coal Bang, and others, not broken hard materials. In addition, the cage Breakers can play a variety of raw materials while mixing the role of broken edge, such as shale fly ash, slag-doped coal industry F-Shek, such as drilling soil fly ash, can achieve good results.

      appropriate, such as coal gangue, shale, mud Lo soil, slag and other materials are available on the roller machine broken. > Roller machine on the biggest shortcomings of the external surface is easy to roll wear, wear caused after the gap between the two roll increase, thus no guarantee that the expected size requirements when the need to be measured use of space and maintenance, and general repair by melting Night grinding way. At present, foreign countries more advanced roll-on roll-skin produced by special wear-resistant materials, wear-resistant materials of ordinary life several times, greatly improving the roller machine on the efficiency and life expectancy, China has yet to be resolved, should this direction efforts.

     Round roller machine at both wet and dry, crushed dry-type round of requests to be broken low moisture content of raw materials, usually in about 6%, so rarely used. Round crushed bodies create simple, * for reliable, easy replacement of worn parts, suitable for grinding hard materials of various size blocks, and can guarantee the required grind size. Wet-round roller machine in the factory is used mainly for raw materials crushed Trainer plasticized, so the next step extrusion molding, especially high-volume fly ash brick, crushed must use round molding machine can guarantee raw materials. Crushed round weight machine's weaknesses are, not convenient for transportation and installation.
