Grinding Cement Clinkers
Most Cement Clinkers grinding experiments were carried out in a 29.2 cm diameter laboratory ball mill which had a built-in wavy liner. The ball charge consisted of 1.27, 1.90 and 2.54 cm steel balls mixed in equal proportion by number.
Simulation of open circuit clinker grinding - ScienceDirect
A mathematical model has been developed for an open circuit two-compartment tube mill grinding cement clinker. Samples were collected of the feed and product, and inside the mill. In the laboratory, sizings were done between the top size and 2 μm, and the breakage distribution function of the clinker was obtained by using a twin pendulum apparatus.

clinker grinding circuit - MC Machinery
Grinding systems are either open circuit or closed circuit. In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.
The cement mill
Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

Indian Cement Review Magazine | Clinker grinding ...
Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost.
An Introduction to Clinker Grinding and Cement Storage ...
Clinker Grinding. The cement clinker is ground as finished cement, in a vertical roller mill for cement or in ball mills similar to those normally used for grinding hard raw materials in dry and semi-dry processes. However, the cement clinker is more difficult to grind than raw materials and must also be finer ground.
