The first step in slag processing is size reduction to liberate metallic iron and ironbearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80% Fe (Shen and Forssberg, 2003).
Although most of the present cement grinding system adopts precrushing equipment, which reduces the particle size of the grinding material a lot, when the particle size of the grinding material is 25mm, the first bin of the ball mill still needs the grinding ball to be in the throwing state, mainly for impact crushing effect, crushing the bulk material into new quot;grainsquot;.
Years of cement production practice shows that cement particle gradation should be distributed continuously within a certain size range. Generally speaking, the cement particles smaller than 32 m are beneficial to reduce bleeding and early strength, but as the size of particles gets smaller, although the hydration activity increases, the voidage of particles will also increase when they
process of cement ball mill. The whole grinding system has great influence on the grinding efficiency. Compared with opencircuit process, cement material can be processed effectively in the closedcircuit process. of finished product. Just like feeding size of cement raw material, the finer the output material, the lower
#0183;#32;Cement is an energyintensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent years, the production of composite cements has been

However, particle size distribution is again a problem, and roll presses are now increasingly popular as a quot;pregrindquot; process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 2040% compared with a standard ball mill system. Capacity of cement mills
In our country, the promotion and use of vertical grinding mill seems a bit slow. Due to the use of habit, ball mill, roller press as the traditional ball mill grinding equipment, which has more than 100 years of history, especially the low cost, the ball mill cement sphericity Gauguin is let very favour of cement plant.
The grinding efficiency of ball mill is low, the treatment capacity is low, the production energy consumption is high, the product fineness is unstable and so on, which are the problems that most concentrators will encounter. How to effectively improve the grinding efficiency of ball mill is an important problem. This article summarizes 10 ways to improve efficiency, if you are worried about
Ball mills are predominantly used machines for grinding in the cement industry. Although ball mills have been used for more than one hundred years, the design is still being improved in order to reduce the grinding costs. HOLTEC has undertaken Performance Optimisation of the cement grinding circuits by doing process

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery and/or mill liner wear and
