The impact crusher is a kind of new type high efficiency crushing equipment. It has the features of small volume, simple structure, and big reduction ratio, high production capacity, production size well-distributed; also have the selective crushing effect. It is promising equipment. But its biggest drawback is the hammer and the back plate particularly easy to wear, especially when crushing hard rock, wear and tear is more serious. Mainly focus on improvement of hammer and rotor structure, in order to facilitate the replacement board and hammer mounted card, counter-attack aircraft (the crushing chamber shaped) structure optimization? increasing energy efficiency.

Secondly, research and develop new kind hammer plate material which is high toughness, and increase productivity. In crusher, the high speed rotating hammer will impact and crush and grind the limestones. For the equipments in long working time is bearing the impact and friction of materials, rotor members are worn, deformation, damaged and will lose the normal work ability, which is inevitable. If we don t do regularly rotor analysis, prediction and do planned life work maintenance and overhaul, eleven emergencies appear, these emergencies will cause severe losses that all production will stop, which is so serious to the enterprises. The main content of repairing and gradation on hammer crusher hammer are: hammer is the main work in hammer crusher parts.

Hammer dish is divided into several parts along the circumference and equipped with N hammers. Adjacent hammer and the hammer can do full circle swinging interlaced in 360 degrees. When the front edge of hammer are worn to the two-thirds of width, the hammer can be turned over to be used again. The worn hammer can do bead weld antifriction alloy and save a large amount of metal material consumption. With its high quality products, hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments. Aggregate crushers are used in mining, quarrying and recycling operations. Several types of crushers can perform this task including hammer mill, and gyratory crushers. An aggregate crusher can be relatively small, like the mobile units used for reclaiming recycled asphalt, or huge machines that can process thousands of tons of material to day. A screen keeps material inside the drum until the rotating hammers pulverize it into pieces of the desired size. These types of aggregate crushers are commonly used to produces crushed stone for landscaping or to process recycled asphalt. Hammer mills are sometimes known as impact crushers. Jaw crusher is the aggregate crushers that are most often employed in large mining or quarrying operations.
