European Technology Coal Crusher also called Coal impact crusher (Impact Crushing for Coal) is mainly processed the coal and other medium-hard Materials like: metallurgy, mining, cement, chemical industry, refractory material, ceramic, etc industrial department with widely application in express highway building, water conservancy engineer, stone crushing for building, artificial sand processing, etc areas, especially suitable for those soft and medium hardness ore of coarse, medium and fine crushing. Absorbing advanced international latest technology, the European Technology Coal Crusher is endowed with an international leading technology by Liming Heavy Industry with newest product. The impact crusher produced by our company is a mining equipment professionally used in breaking ore,which is also called mining impact crusher or stone impact crusher.At present,we launch a new brand of impact crusher:mobile impact crusher.It is more convenient and easier to use than the previous impact crushers,and not confined by topography.The industry calls it movable impact crusher production line. However,its biggest disadvantages are its vulnerable board hammer and impact board.Especially when breaking hard ores,they need to be replaced frequently.Owing to the appearance of some wear-resisting materials at present,this series of impact crusher has been used in some concentrating plants. There are two types of coal impact crushers. The Horizontal Shaft Impact Crusher (HSI Crusher) and the Vertical Shaft Impact Crusher (VSI Crusher). The HSI crushers break rock by impacting the rock with hammers that swing on a rotating shaft. The practical use of HSI crushers is limited to soft materials and non abrasive materials, such as coal, limestone, phosphate, gypsum, weathered shales. HSI crushers achieve the highest degree of reduction. The VSI crushers can also break rock by impacting the material with rotating hammers, traditionally this is referred to as a "Shoe and Anvil VSI" and has similar limitations to the HSI crusher. In the future development,Shanghai Minggong will actively focus on the core technology research and development, the capital operation, brand building, marketing and other key links. Roll crusher, coal slime dryer, cone crusher, dryer machine are the main processing and crushing equipment in the market. If it can ensure the same quality, price and delivery conditions, the large enterprise can deliver other factories to processing, which will improve the local factories' ability of produce mating parts and strength the leading role in local economy to get better development.

Direct Preferential Flotation
Definition of this method is: separate various helpful minerals in proper order. With its feature of high flexibility, it can adapt the change of ore grade, especially for sulphide ore of high grade. Xilin, Fankou, Lechang lead-zinc dressing plant of our country, and Laisvall lead-zinc dressing plant of Sweden all adopt this method.

Combined Flotation Flowsheet
Firstly, get mixed concentrate through the emersion of all useful minerals in ores; secondly, separate various helpful minerals in sequence from mixed concentrate. These two steps together are called part of amalgamate flotation Flowsheet. This process is suitable for treat raw ores of complex structure, fine embedded grains, and low content of sulfide mineral, which are in close symbiosis relationship. Because this process can simplify process, reduce ores’ over grinding, so as to benefit separation. Almarc Lead-zinc plant of former Soviet Union adopts preferential flotation this process. By using this process, we can get higher index than preferential flotation improve 10% of lead concentrate ore grade and 4.5% of zinc concentrate ore grade, raise the rate of multipurpose utilization from 75.4% to 83.7%, and double labor productivity. Qingchengzi zinc-lead ore dressing plant and Xiaotieshan copper ore dressing plant of our country adopt this process.

Part of Amalgamate Flotation Flowsheet
We can get mixed concentrate by the emersion of two useful minerals in ores together, then separate single concentrate from the mixed concentrate. The two stages together are called part of amalgamate flotation Flowsheet, which is the most widely used process in production. It is quite economical to adopt this process when raw ores contain low-grade nitrogen, copper-lead, copper-zinc, and lead-zinc.

Iso-flotability Flotation Process
According to minerals’ flotability in ores, mineral assemblages of good, medium and worse flotability are separated through flotation separation. Secondly, different helpful minerals are selected out from all mixed concentrates, which is called iso-flotability flotation process. For example, Huangshapinng lead-zinc ore dressing plant of our country, and Zheskaz of former Soviet Union both adopt this process. beneficiation,Mineral Processing,rotary kiln
