Limestone is a major sedimentary rock composed of calcite. Limestone can be directly processed into stone and fired into the quicklime. Lime has quicklime and hydrated lime. A lot of lime and limestone used as construction materials, an important raw material in many industrial lime production, most of the materials need to go through crushing, for the next pre-homogenization, storage, ingredients, grinding, drying, conveying process create good conditions.

Crusher crushing limestone Ningxia, Shanghai, Hongxing crusher experts pointed out that mainly the following process: The first step is to free broken phase, the material into the crushing cavity, immediately subject to the impact of the high-speed board hammer, the material between friction between the impact, the board hammer and materials and material, so that the materials are crushed ceramic ball type mill crushing cavity.

The second step is the board hammer, high-speed impact and the rebound effect of the back plate, so that the material is broken by the repeated impact machinery. Board hammer solid in a high-speed rotation of the rotor, and several blocks back plate arranged at different angles along the crushing chamber. Materials into the role of the board hammer area first by the board hammer, the first impact of the initial crushing, and at the same kinetic energy, high-speed toward the back plate. Material and back plate collision broken again bounced back into the role of the board hammer area, re-board hammer impact. And so forth, from the plane until it was broken into the desired particle size.

Iron ore crushing machine should continue to develop, improve their technical level and performance advantages, not only reasonable for the use of iron ore to perfect the use of other mineral resources in the country also has a role in promoting. Period of rapid growth in the iron ore crushing machine, over the years to R & D and production of a variety of fine crusher equipment Henan Braun also learn to follow-up, equipment continue to improve and perfect step by step to improve its current reached a certain level of technology. In the critical period of development of the national steel industry, iron ore crushing machine to forever preserve its power for the use of iron ore for the steel industry to pave the way.

Mining equipment for energy, transportation and raw material base of industrial sectors, the main task is to deep processing of coal, steel, nonferrous metals, chemicals, building materials and the nuclear industry sectors such as mining and raw materials, as well as railways, highways, utilities the major projects under construction to provide advanced, efficient technology and equipment. Mining machinery is the machinery industry in a wide variety of device structure is complex, high demand, the use of a wide range of machinery industry. Mining machinery such as sand maker and vibrating screen and its uses can be broadly divided into mining equipment, lifting equipment, narrow rail transportation equipment, crushing grinding equipment, mining, screening equipment, washing equipment and roasting equipment categories, 30 subclasses, more than 700 varieties and thousands of specifications.
