Do In practical mining production, we often have the problems of quick-wear parts? cone crusher?. It affects equipment performance and production efficiency. It is a regularly work for mining machines maintenance. Should we really want to keep machines good condition, we have to learn repair at least daily. At first, as we all know, we should protect machine from damage or hitting. Ensure clean of them and cannot make contact with chemical things machine. Besides, is responsible for the whole operation bearing load. It is important to prolong bearing service life. Good lubrication does much with operation efficiency, as well as bearing use life. Above of all, the pouring lubricating oil must be clean, and sealing is good. Lubrication is the process, or technique employed to reduce wear of one or both surfaces in close proximity, and moving relative to each another, by interposing a substance called lubricant between the surfaces to carry or to help carry the load (pressure generated) between the opposing surfaces. The interposed lubricant film can be a solid, solid/liquid dispersion, liquid, a liquid-liquid dispersion gasses exceptionally to gas. In the most common case the applied load is carried by pressure generated within the fluid due to the frictional viscous resistance to motion of the lubricating fluid between the surfaces. Fluid film lubrication is the lubrication regime in which through viscous forces the load is fully supported by the lubricant within the space or gap between the parts in motion relative to one another (the lubricated conjunction) and solid solid contact is avoided. Hydrostatic lubrication is when an external pressure is applied to the lubricant in the bearing, to maintain the fluid lubricant film where it would otherwise be squeezed out. University lubrication is where the motion of the contacting surfaces and the exact design of the bearing are used to pump lubricant around the bearing to maintain the lubricating film.
Old-fashioned crusher is generally using high manganese steel, this kind of hammer crusher of limestone broken cycle is short, use resistance, abrasion resistance loss was not enough. With the development of technology, high manganese steel has appeared hammer head and double alloy hammer. Double alloy hammer, usually three forms: one is, in the work of hammer head on a layer of hard alloy welding, improve the hammer and anti-wear properties; Secondly, in the controlled, improve the working parts of the hammer head chromium casting alloy (mainly) content: the third was, in the work place, hammer head set hard alloy or alloy piece stick. Grinding process is to examine the purpose of grinding and classification process of the operating process conditions, technical specifications, operational efficiency and determination to conduct a comprehensive test. Through the process of the product number, concentration and particle size determination, calculation and comprehensive analysis, which found problems in production, in order to make technical improvements to the mineral processing technology and economic indicators to a new level. Study on methods of grinding ball mill and crushing process, sorting process similar to the test. Let s take a look at the preparations before the visit: 1 Because of the heavy workload test, the required human and more in the test must be clear before the purpose and content of the test, make full preparations for human and material resources. 2.Because the stope mining and crushing of the final product size to investigate to ensure that test during the mill to the mine representative.
3 For grinding and classification equipment operation and integrity of the investigation, the maintenance arrangements for the timely maintenance to ensure that the sampling device during normal operation. 4 Arrange the sampling points of sampling personnel, sampling tools and containers containing samples and posted a good label. Some experts predict that the pace of development of mining machinery will slow down, so now consider the post-industrial mining machinery and domestic and international market demand is not early. Mining machinery manufacturing industry in the current process of design is relatively weak business case, in addition to good conditions in their own areas of expertise into the role of organizational strength as soon as possible, should be taken with foreign companies and professional design institutes to establish different forms of joint, including formation of groups, the Commonwealth, technology, personnel and other measures to introduce, at least to strive to take on the project in a joint design approach, the first intervention and then increaseso a win-win, and they are mostly ineffective recklessly to lay.
Either the construction industry or the high-speed rail, highways and other construction, they are all the basic construction of the country, and they can not do without the use of gravel in the construction of each item, so the development of these industries also contributed to the invisible sand and gravel industrydevelopment, and community development. Mountain climbers in heavy industry insiders analysis, future development, use of gravel will gradually increase, and sand making production line requirements become increasingly high, not the demand of different industries on the same gravel. In order to meet the needs of different types of gravel, sand making production line machinery and equipment requirements have become more sophisticated, more stringent each gravel equipment manufacturers are constantly on these machines to be updated updating in order to keep up with the trend of the times, to catch up with consumer demand, but even in the pursuit, constantly updated, and each company s technical support, production of the machine s various performance and the use of life etc. aspects are not the same. As we all know, the crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors.
Common crushing machines are winnowing mill, hammer breaker, breaker, roll crusher, crusher compound impact. Jaw breaker (jaw breaker), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. As china s advanced the gravel equipment manufacturers, both production technology or product quality of our company walk in the forefront of the country, and we will continue to develop and experiments on sand production line. Independent research and development of various products used in the manufacture of machine wear-resistant materials, enhanced continuous improvements in various parts of the service life of the equipment, and increase the total system of sand in a certain period of time, to achieve the advanced level in China, no longer need a cumbersome process, reducing the time and energy wasted during maintenance and easy maintenance, allow consumers to create a higher profit in the same period of time. Which has also accelerated the construction of our infrastructure. original link: rock crushers: Sand maker:
