What is the function of ball mills’ the static and dynamic pressure bearing, what features of their design to meet these functions? Static and dynamic pressure bearing is a hydrodynamic lubrication have both static buoyancy effect of the bearing. To achieve the above functions, the configuration of the high and low pressure hydraulic station. Before the start and stop the ball mills when worn, high-pressure pump into the pressure of 30MPa for high-pressure oil, the Ministry of rotation float, forming about 0.1 ~ 0.25mm the film, this time from the top to achieve static pressure, can reduce the start load and impact, to avoid abrasions bearing, improve the operation rate. Even if you stop running, this layer of film still exists. After 10min the normal operation of ball, stop for high oil, low pressure pump to work, into continuously for pressure0.5MPa of low pressure oil to form a dynamic pressure oil film, and ultimately from the top of the static pressure, dynamic pressure lubrication and bearing temperature reduction function. Stop running mill, high pressure pump into the high pressure oil supply again, the journal will cover float. This design greatly extends the service life. Run into by the main motor is stopped, the high-pressure pump starts automatically stops automatically after 10min delay. When running in bearing temperature is higher than 55 degrees, high-pressure pump starts automatically after the test bearing temperature 10min delay, less than 55 degrees when the automatic stop. Hydraulic station hydraulic model L-HM46 # hydraulic oil, low pressure pump (lubrication pump) for the 2 groups vane pump, working pressure 0.5MPa. Low-pressure pump is responsible for the supply of oil and high pressure oil pump, low pressure pump work after 8h and standby pump automatically switches the pump, high pressure pump and then automatically stop after the host is running 10min. High and low pressure lubricated main bearing lubricant stations, including startup and shutdown of the high pressure low flow and low pressure during normal operation of a large flow of lubrication.
Vipeak Heavy Industry Machinery Group Company is a high-tech mining machinery company in China, The product Straight Centrifugal Grinder, and the HGM Series Three-rings and Medium-speed Micro-powder Grinder are our latest research results, which are also the most forward powder grinding equipment at domestic researched by the mining equipment expert and powder grinding expert of our company in more than 10 years. At present, under the same energy consumption the output of this series equipment can be increased to 2~8 times, this resolves the difficulty of lower output in traditional grinders. At the same time, on the basis of original grinding mills, the finest size can be 3500 mesh.
We are tirelessly dedicated to the hi-tech all the time, and the cooperation with Svedala industries AB Company is our first step to introduce the international leading technology. At present, the exchange and cooperation of technology of both company go well, so the two sides achieved a win-win situation.
We pay more attention to scientific research and development, and stick to putting 20% of its annual income into product development so as to perfect research technology as well as develop, debug, and produce equipment, to improve the hi-tech contained of the product and to create a famous international brand. And also we have established Vipeak Heavy Industry Research Institute, which played an important role in the technology of Vipeak Heavy Industry.
Vipeak Heavy Industry Group Company Research Institute is of capable comprehensive mining equipment technology research institute, which is also authorized to be the first batch of state-level research and development center by the State Economic and Trade Commission and gained a Class A Heavy Mechanical Engineering qualification. The research and development center has been undertaking the Heavy Mechanical basic research, the whole set equipment research of key projects and craftsmanship, the development of project equipment and major national technology equipment and new products development work for a long time.
