The choice of aggregate industry
We provide all kinds of crushing machines including stationary crusher and mobile crusher
In the cement industry, one of the main topics is reducing the energy consumption. In the cement manufacturing process, cement grinding accounts for approximately 40 % of the specific electrical energy requirement. Two-compartment ball mills operating in closed circuit comprise the primary technology for grinding cement.
The Efficient Grinding Solutions webinar is part of the KHD Technical Webinar Series that will cover a range of topics from across the cement manufacturing process, including: Parts Services (28 July) Intelligent Solutions for Cement Production Automation Process Training Simulation (11 August) Cooler Solutions (25 August)
in cement grinding is the time taken by material to attain the required particle size before it reaches the mill outlet. Retention time can be reduced by the use of a closed mill grinding system
This is called a combi-grinding circuit. The main feature of such a system is the pre-grinding of cement clinker in the POLYCOM and a final grinding in the ball mill. The specific power consumption compared to a ball mill cement grinding is significantly lower and additionally paired with a

2015-12-1 Efficient grinding. Comminution and especially cement grinding still account for the majority of the electrical energy demand of cement production. As Fig. 12 shows, between 60% and depending on cement properties up to 70% of the roughly 100–110 kWh of electrical energy per ton of cement are used for comminution processes , . It has to be ...
2011-12-6 Efficient grinding can only be achieved by maximizing the feed throughput, rapid removal of the desired fines to avoid over-grinding, transferring of optimum impact / shearing forces from the grinding media to the materials being ground minimize generation of wasteful heat, wear, vibration noise. Energy consideration in cement grinding
In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding. According to some hypotheses, only a thousandth blow of the ball is spent on grinding the material.
