subject: 2012 Is The Outstanding Times For Lime Mill [print this page] Lime ball mill is the key equipment of grinding material, widely used in grinding production line. Mill use include: cement, silicate, new building materials, fertilizer, black or colorless metal processing. But the mill during operation frequent failure in the following points : the lime ball mill equipment supply shaft lubricating oil interruption. Sand into the lime ball mill bearing. Hollow shaft lubrication. lime ball mill cylinder body around the liner weight imbalance, or wear uniform. lime ball mill gear excessive wear.
For the production of enterprises, reasonable selection of the type and amount of Lime mill grinding equipment direct structure is to improve the overall performance of grinding process of prerequisite. However, in most of the actual project, the whole structure of lime mill grinding process and selection of equipment has been established, so in the actual process, the selection of control strategy and controller design has become the most direct factor affecting grinding process, along with China's national energy saving policy, industrial Lime mill grinding process of high energy consumption and low energy efficiency has not meet the current requirements for equipment, therefore to seek a feasible optimization scheme makes the lime mill grinding process to reduce energy consumption, improve the yield, become a priority among priorities.

In the lime mill is enabled, the hybrid bearing a new type of sliding is developed on the basis of dynamic pressure bearings and hydrostatic bearings main bearings. lime mill before the start of the first open the high pressure oil of the high-pressure lube station, a certain number of high-pressure oil into the static pressure oil chamber. Lubricant begins with a certain amount of pressure oil chamber to the surrounding space to spread out. When the high pressure lube station to the static pressure oil chamber oil, while its total intake from the oil chamber outward leakage, change the formation of a stable hydrostatic oil film to bear the external load. At this point, start the lime mill. Full-liquid friction coefficient is small, and thus, the starting torque of friction lower than the dynamic pressure pulley about 40%. lime mill, therefore, static and dynamic pressure bearing both dynamic pressure bearing role of the hydrostatic bearing.
Corporation culture is the motive power of one enterprise. Talent, technology and management are everything. Hongxing Group always pay attention to construction of corporation culture since it set up. Nowadays we have already shaped unique corporation culture which has greatly stimulated the fast development of Hongxing Machinery Company.
