With the application of new type highabrasive materials, Hongxing produced impact crusher at the first time to break traditional limitation. Although the improved type is still in the process, the type in application is only used to crush middle hardness materials.
Under the hammering action, materials are crushed firstly from the most fragile level. This kind of crushing will get high ratio of cubic-shape materials. Then the needle flake percentage could be lower than 10% instead of higher than 15% by Jaw crusher, cone crusher and roller crusher in the production. Hence it could limited the application of impact crushers.
It is the machine that makes use of the rebound function of the high impact force of the hammers and the impact plate to make the material be impacted repeatedly into pieces. Impact Crusher can effectively handle the large amount of moisture content of materials, to prevent the blockage of the phenomenon of Crusher. The hammers installed on the rotors with high rotation speed, and along the crushing chamber, there are some impact plates laid on the different angle. When the materials get into the area which the hammers affect and under the impact function of the hammer at a high speed, then the materials will be thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for being recrushed.
In dealing with excessive moisture content of materials, the counter-attack crusher feed chute and the back plate can be equipped with heating devices to prevent the bonding material. Impact Crusher is equipped with the bottom of the sieve plate do not need to be effective in preventing clogging phenomenon. The hammer crusher can not be used to prevent heating of the bonding material, and shall be equipped with the bottom of the sieve plate, increasing the possibility of clogging.
Impact Crusher spare parts replacement is simple, a corresponding reduction in maintenance costs Broken rotor only counter to install six panel hammer, special tools can be easily board hammer replacement, the replacement of a board of only one frequency hammer time. The bottom of the grinding chamber grinding rod replacement also requires only several minutes, greatly reducing the repair and maintenance time and costs. The hammer crusher hammer up to more than 100, with the replacement of a hammer to spend a lot of time and manpower, repair and maintenance costs higher. The bottom of the screen plate and its replacement is also troublesome.
As the professional manufacturer of complete sets of mining machinery, such as Rock crushing plant,Sand making machine, Henan Hongxing is always doing the best in products and service.来源：https://www.cnblogs.com/liajones/archive/2012/02/27/2369891.html
