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.

It can increase the cement fineness, improve cement production and improve comprehensive performance of cement significantly by adding grinding aids, and promote the use of grinding aids in reducing the energy consumption of cement production, with the adjustment of national economic growth and the elimination of backward production capacity. But the effect mechanism of the grinding aids is divided, and the grinding effect of the system is still need to be improved. In this paper, the development history of cement grinding aids is introduced, and the grinding aids are summarized systematically from the aspects of the grinding mechanism and present research situation at home and abroad. Study shows that current research only stay on the level of practice, not related to the in-depth research on the theory system and theoretical model, a set of grinding efficiency of composite grinding system and the corresponding scientific theory are need to establish.

The process of liner wear and the changing characteristics of the ability of crushing and grinding in the coal pulverizer are analyzed, a new type of cylinder liner is developed, which has a multi-step wave crest. The small balls on the liner are stuck by the steps, in this way, the wear of the liner wave crest is lightened, so it can keep a long-term stability, it also can take the balls to a reasonable height, increase the number of the balls which are taken by the wave crest and make the dropping points scattered, as result of that, it substantially increased the coal pulverizer's crushing and grinding efficiency; Also the wave crest of the liner can be dismantled from the base plate and individually replaced, so it made a great reduce in the material consumption of liner. The test shows that, with appropriate use of the balls, the liner can reduce the ball charge by 35-50%, reduce power consumption by 30-40%,it also can keep the coal pulverizer's output and improve milling fineness.

Based on retrieval for domestic and international literatures about the grinding fluids special for ceramic machining use, this paper put forward a method to enhance the engineering ceramic grinding machining efficiency using the organic grinding fluid added with the long chain alcohol The experiment, performed on the constant force cutter, greatly increased the ceramic grinding efficiency by 2.4 times through the comparative experiment for several normal grinding fluids as well as by adding additives. In addition, this paper conducted the matter structural analysis for the liquid-solid interface using the Raman Spectrum technology and preliminarily discussed the mechanism of this grinding fluid.

This study selected three types of organic substance as the main components of high-efficient organic grinding liquid for grinding ceramics with silicon. The grinding efficiency test was conducted on the basis of self-developed grinding mechanism and the findings indicated that the grinding performance of all these three types of grinding liquid were better than average grinding liquid. With Si3N4 Ceramics as the representative test material, the grinding efficiency can be increased at least 1.37 times and more than twice with the grinding fluid prepared with oleic acid or oleic alcohol. The analysis of liquid-solid interface with the help of infrared spectrum showed that there existed abnormal vibration peaks in the liquid-solid interface between Si3N4 ceramics and grinding liquid with (organic substances)–OOH and -OH under normal temperature, which resulted from the adsorption effect of hydrogen bond generated between organic molecule and Si3N4 ceramics. Under high grinding temperature, the friction chemical reaction took place as the result of the absorption effect and the resultant could not only reduce the surface hardness, but also improve the lubricating effect, thus improving the grinding efficiency and surface quality.

The problem of grinding process increase for machine parts surfaces can be solved by means of abrasive disks design updating, their composition and impregnation technologies. The structures of multiple grinding wheels containing rods in a basic abrasive mass including conducting elements are offered. Such disks allow increasing quality in surfaces machined of parts made of tough hardtomachine steel and alloys on the basis of nonferrous metals on indices of roughness, technological residual stresses and burns. High efficiency show multi-sector abrasive disks of different grain allowing the increase considerably the intensity of material removal at machining parts made of chro-mium-nickel steel and alloys. The effective composi-tions of abrasive masses are developed for tool manufacturing including the introduction in them highstrength ferritic iron, chromium diiodide and wood resin. Polishing tools made of abrasive mass have 1.5 –twice higher durability between stropping operations and ensure the decrease of burn areas quantity on ma-chined surfaces of parts 2-2.5 times. The promising direction of the efficiency increase in parts surface grinding is the impregnation of abrasive disks by an aqueous solution of chromium diiodide which possesses high anticeptic properties and at the iodine emission forms iron iodides with a low constant of friction. As a result of this the temperature drops in the grinding area by more than 30%.

It is an effective method to enhance the engineering ceramic grinding efficiency using the organic grinding fluid added with the long chain alcohol. In the cutting-grinding experiment, the ceramic grinding efficiency was 2.4 times higher than the common grinding fluids. The microstructural analysis and the hardness testing performed for the liquid-solid interface using the Raman Spectrum technology and the nano impression technology found that there were abnormal peaks in the Raman Spectrum of the liquid-solid interface between the ceramics and the organic grinding fluid and the presence of abnormal peaks was familiar with the changing rules of surface hardness. The effect might change the grinding mode of the diamond grain micro-blade in the grinding process, thus to affect the grinding efficiency and the machining quality. It is a research direction to be further discussed.
