Crushing plant is an important part of dressing ,it is also the key to reduce costs. Main consumption, screening efficiency, quantity of ore processing and size of final product is a the four main technical and economic indicators of crushing plant .
1.Main consumption: In addition to crushing plant equipment, normal wear and tear, electricity, steel consumption, lubricating oil, water, tape is its main consumption items, the maximum size of its consumption with the ore, ore size distribution, type, hardness, crushing process and the crushing ratio and other factors vary. The power consumption of the most prominent, accounting for the whole plant of 6-9% of total energy consumption thus reducing the energy consumption is to reduce the crushing cost effective way to increase economic efficiency.
2.Screening efficiency: it is a measure of mechanical work and inspections sifter important indicator of good and bad effects, so even if the screening efficiency should determine, if found inefficient screening, should promptly identify the cause as soon as possible to resolve, or will load increase circulation and reduce the crushing efficiency, increase the crushing equipment wear and energy consumption. Practice should be made to the screening machines and uniform amount of ore.
3.Quantity of ore processing: crushing ore processing plant is that it’s important quantitative indicators, it should be provided for the grinding plant size qualified, adequate and there is a certain amount of ore reserves. To ensure the normal operation of grinding, crushing plant processing ore that is the section dealing with ore crusher, therefore, enhance the machine’s table gravel stages of processing capacity, reduce equipment idle, when the best economic , an important way to reduce the consumption of one unit.
4.Size of final product : crushing plant size of final product is that it’s an important indicator of quality. At present, the sorting operation is usually divided into the crushing and grinding the ore refined in two stages, the final product size in addition to the crushing phase of the economic benefits of this important next phase of the effects of grinding operations have a direct impact, if crushing the final particle size increases, can crushing costs, but the grinding costs, so the second phase should be based on the principle of total economic benefits of the best color, best determined by accounting for crushing the final product size. Practice to ensure that the final product particle size means there are two, one, the use of closed-circuit crushing and screening process should be kept in check the mechanical integrity of the screen surface, such as leakage shall promptly repair or update; Second: the use of open crushing machine crushing process when the response time of discharge port test, are subject to change and regulating.
