Vast Technology Improvement Of Impact Crusher

The crushing operation is divided into a variety of modes of action

. The common operation is crushed, split, broken and grinding stripping, etc. Different mode of action will have different considerations. Compressive strength of the ore should be considered during crushing. Mineral tensile strength need to pay attention to splitting the materials. The bending strength of the ore should be considered in the broken operation. The shear strength has become the main consideration in grinding stripping ore. The impact crusher is a crushing equipment which sets above a variety of forces repeatedly on mine. Its impact strength should be seriously considered because it has a certain impact effect.

Traditionally, the impact crusher is one of the crusher specially used in burning lime. Although the impact crusher is with the characteristics of big crushing ratio, the wearing parts is easily worn owning to the impact of the plate hammer, which causes the increasing cost of wearing parts as well as the reduction of the crushing amount. As with this phenomenon, Zhengzhou wear-resistant materials research institute make efforts to upgrade the technology of the board hammer, impact scaleboard and other components.

As we all know, the worn of the impact crusher plate hammer only appeares in the side facing materials. When the rotor rotate at a normal speed, the feeding materials will fall to the board surface of the plate hammer, it won't be worn the plate hammer back and flanks, even the side facing material wear also rarely. But when the rotor rotate at an abnormal speed, the plate hammer will be worn easily.

The former board hammers are usually made from high manganese steel, which is suitable for crushing materials with medium hardness, but when it crush such as basalt, diabase, biotite, granite and other high hardness materials, the plate hammer must have good corrosion resistance as well as high wear resistance. Nowadays, the generally used plate hammer is mainly made by high chromium cast iron, and high chromium content means relatively good toughness. However, high chromium cast iron brittle and its high price promotes the continuously research of new wear-resistant materials.china cement mill:http://www.hx-crushers.com/p47.html

Reportedly, after many experiments as with the crushing characteristics of impact crusher, reasonable application the most advanced nanotechnology, experts of Zhengzhou Materials Institute has developed the new casting wear-resistant materials whose sexual price is at present 1-2 times higher than the general materials, which compared with similar imported products, semi solid extrusion hypereutectic high chromium plate hammer has the advantages of high security, high wear resistance, low in price and greatly shortened delivery cycle.

Impact Crusher is the first choice of crushing in stone crushing line. The Impact Crusher is widely applied in mining, transportation, energy, construction and chemical industry. For crushing and screening, it's better choice. The most outstanding advantage of Impact Crusher Machine is that its finished powder is in good, cubic shape and without tensility and cranny. Our impact crushing equipments are accurate, reliableand and have perfect performance. We manufacture and supply portable, stationary impact crushing plants and equipments.
