Several Advantages

We all know that there are varieties of crusher types, but all of them have different strengths and weaknesses, applicable materials are also different. For example, compare the impact breaker hammer breaker and, the former has the following advantages: 1, the expected size adjustment is convenient, flexible, and the range is wide Impact crusher our company produced can adjust the feed size through a variety of ways, such as the regulation of the rotor speed, adjust the counter plate and the gap of grinding chamber; the gap adjustment can be achieved by mechanical or hydraulic type, if we adopt the hydraulic adjustment system, we can conveniently to press the operation button or shipping distance control system to adjust the gap; While the discharge particle size adhustment can only be achieved by the replacement of the bottom plate. Impact breaker can crush both soft and hard materials plate hammer of the hammer breaker can be firmly fixed on the rotor by the mechanical clamping structure, when the great moment of inertia with the rotor rotates. compare to the breaker (hammer was hanging), breaker rotor impact hammer HA greater momentum, adapt crushing hard materials have lower energy consumption at the same time. 3, can deal effectively with the materials which contain large amount of water, anti-cloggingwhen processing the materials which contain excessive moisture, feed Speedball and counterattack board of the impact crusher can be equipped with a heating device to prevent the adhesion of the material. Crusher is not required to be equipped with the bottom screen to can effectively prevent clogging. Hammer crusher can not prevent the bonding of materials by heating, and shall be equipped with the bottom screen, increasing the possibility of clogging.

4, the wear and tear of wearing parts is smaller than the hammer crusher, the metal utilization is high as to the impact breaker our company produced, its wear only appears at the looking materials side.Normal rotor speed, feed plate hammer will fall to the surface (of attack), the plate hammer back and sides are not to be worn. Even Looking material side wear very little.And the bottom of the grinding rod is also very easy to replace. Impact crusher board hammer metal utilization rate can be as high as 45 % -48%. hammerhead of the hammer crusher is hanging, wear and tear occurs in the upper, front, rear and side, compare to the plate hammer, hammer wear more serious, hammer metal utilization is only about 25%. And the rotor body itself may also be subject to wear. Single toggle jaw crusher: Hammer crusher:.

Vertical Impact Crusher

A large number of gravel field in North America use the Ellay VSI vertical shaft impact crusher produced Cedarapids bySand. The biggest characteristic of this type of is the running speed is faster than Bamare machine type, therefore, the wear of the impeller and anvil hoop are relatively small, but the product qualified grain output rate is high. The Original Nordberg launched VI series of vertical shaft impact crusher, its structure is basically similar to Cedarapids Ellay VSI production type, the difference is that the outer lining, drum liner can rotate ring, The idea is to make the bushing continue work in rotation to extend life, but if we analysis structure, when the roller was filled from materials constantly, the rotating roller will lose its rotating characteristics, In addition, non – positive impact between the material and the drum speeds up the local wear of the roller. I saw model is actually the Svedala rotor, Nordbert, drum liner ring.so the the Svedala rotor inadequacies exists in Nordberg also. It is Recently reported that Svedala launched the production which is similar with Cedarapids EIJay s vertical shaft impact crusher type, I believe Nonlberg is bound to change the design of the VI series and go EllayVSI broken machine road in future. Shanghai Dowling Watson Machinery Co., Ltd. has developed PLC series vertical impact crusher. The prototype is the U.S.

model the Cedarapids company C vertical shaft impact crusher which characterized by simple structure, large capacity, unobstructed discharge and both can be used to crushing and devoted to sand, the product grain shape is good. It contains? do is 900 mm,? 1 000 mm? 1170 mm 3 overall sizes. Shanghai Longyang Machinery Factory absorb the successful experiences of the domestic and international vertical shaft impact crusher, exposed the old problems in use and improved, now, assessment of industrial operation is completed, which the styling products will promoted to market: Zhengzhou Yifan Mechanical Equipment Co., Ltd. constantly improve the product on the basis of years of salts, which is now maturing, the structural strength and stiffness are greatly improved, especially the improvement in the structure and material impact heads, after the long-term using, its life is over the import prototype (in the same conditions) and leap to the domestic advanced level. Vertical impact crusher manufactured by the company ranks first in China s domestic market share.
