The jaw crusher is an old broken equipment, Speaking of jaw crusher can be said to have a long history of broken equipment, review its development history, dating back to last century, in the last century, the resistance of jaw crusher grinding pieces of movable jaw after several generations of technology improvements, but overall, did not produce changes in the nature of the face of what kind of jaw crusher to achieve the ideal wear resistance of the industry? This technical subject, Henan Hongxing Machine After several experiments, the only moving jaw of the moving jaw of the original composition of efforts to bring in foreign technology in order to achieve the desired requirements and standards.

The jaw crusher is currently the most widely used in all walks of life, crushing equipment, jaw crusher is generally used for the crushing of a variety of different hardness, different nature of the material, which requires a good jaw crusher should have good self-protection systems, equipment safe operation, the failure rate remained at a low level. Shanghai Minggong machine crushing equipment experts pointed out that: efficiency and production costs of the service life is directly related to the jaw crusher jaw crusher board, it is particularly important to extend the service life of the jaw crusher broken plate. Super wear Shanghai Minggong machine moving jaw jaw crusher series are a new generation of highly efficient, energy saving, low wear and crushing equipment. Use of current technology level, through the side plate of the movement of the eccentric shaft transmission to the outside of the movable jaw. The benefits of doing so is to make the broken equipment kinematics and dynamics performance has been fundamentally improved, resulting in improved device performance. Shanghai Minggong machine moving jaw improved jaw crusher using multi-combination with other crushing equipment, such as grinder, ball mill, to constitute a loop through the grading machine and conveyor after the formation of the entire process to ensure that the degree of fragmentation of the ore or raw materials to achieve the best standards and requirements.Shanghai Minggong Machine large jaw crusher has a crushing chamber deep and no dead zone, the feed is smoother, higher yields; its big crushing ratio, uniform particle size; Gasketed nesting population adjustment device, reliable, easy to use. The adjustment range and increase the flexibility of the device; simple structure, reliable operation, low operating costs.
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 http://www.dryballmill.com
