Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.
Cement mill separator, or cement separator, is a type of equipment that was widely used in the cement grinding system and raw mill system of cement plants.The function of the separator is to separate the fine-sized particles from the coarse-sized particles, so as to avoid material condensation and over grinding in the mill, and improve the milling system's grinding efficiency.
Higher cement production rate leads ... for the cement to pass through the mill. If the mill retention time is reduced too much, the cement is insufficiently ground which leads to increased separator rejects and hence a reduced production rate. Traditional grinding aids are based on amino alco-
A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Cement production in the world is currently about 1.6 billion ton per year. About 2% of the electricity produced in the whole world is used during the grinding process of raw materials .While total electrical energy consumption for cement production is about 100 kWh/ton of cement, roughly two thirds are used for particle size reduction .About 65% of the total electrical energy used in a cement ...
A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It's mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part,discharging part,rotating part,transmission part (reducer,samll transmission gear,motor,electric control) etc.

The cement ball mill has reasonable structure design, simple operation, large handling capacity and low failure rate. The wear-resistant parts are made of ultra-wear-resistant materials, which can reduce the exchange cost of the vulnerable parts and control your production and maintenance cost.
The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.

The rate of wear is greater in a ball mill but the cost of replacement is lower. On the other hand, the wear rate is lower in VRM, the cost of replacing the parts is significantly higher. Product Quality. When VRM was first mooted as an alternative in cement production, one of its seeming challenges was its particle size distribution (PSD).
