Grinding System

In mineral processing the high material volumes yield the fact that benefits of even small improvements in the production quality and product efficiency are remarkable. During the operation of the mineral material processing, the grinding circuit (GC) is the key unit and its product particle size and circulating load are two controlled indexes directly related to the quality and efficiency of the whole mineral material processing. Therefore, an appropriate control of GC is especially significant to improve the operation performance of the mineral material processing. Due to the GCs are essentially multivariable dynamic systems with high interaction among process variables. It is hard to improve the quality and efficiency in the mineral material processing by controlling the grinding system with the conventional methods. In this paper, a novel multivariable decoupling control scheme is adopted to handle such intricate process. Simulations have shown the proposed method can greatly improve the production quality and product efficiency of the mineral material processing.

High Energy Consumption

In cement industry, many grinding up systems are on operating now. The tradition process of tube mill grinding system is high energy consumption, so it’s low efficiency, especially in the final cement grinding process. The value and advantage of slag is recognized more and more, but it’s difficult to be grinded up. Furthermore, the disadvantage and shortages to grind up clinker compounded with slag to produce cement are obvious and adopted. The best process is to grind up slag, clinker separately. Then, these two kinds of powder are compounded by a mixer. Hereby, it introduces a design of the process to grind up clinker, slag by one roller mill.

Parallel Grinding

Parallel grinding is an effective method of aspheric moulds machining which is usually made of industrial ceramic such as silicon carbide (SiC) or tungsten carbide (WC), but if the spherical grinding wheel is not being with precision truing and dressing, the roughness and form accuracy of the ground aspheric surface should get worse, for this reason, in this paper, the influence factors of thoroughness and form accuracy induced by the wheel truing and dressing are studied firstly, and a new 3-axis CNC Ultra-precision grinding system which is based on the PMAC (Programmable Multi-axes Controller) is developed, through simultaneous motion of the controlled X, Z and B axis, the form errors which is induced by the grinding wheel can be improved theoretically, and the aspheric mould machining test shown that the surface roughness of Ra 0.025μm and the form accuracy of P-V 1.15μm are achieved.
