Water Spray in Cement Mills. Water spray installed generally in second compartment of ball mill to control cement temperature. Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set.
Grinding occurs at the beginning and the end of the cement making process. Approximately tonnes of raw materials are required to produce 1 tonne of finished cement. The electrical energy consumed in the cement making process is in order of 110 kWh/tonne and about 30% of which is used for the raw materials preparation and about 40% for the ...

The better mills on the market have an efficiency of about 89 % which means that only 89 % of the energy results in grinding and the majority is converted mainly into heat. The ball mill has the worst efficiency of all types of mills on the market. Just 4 % of the energy is used for comminution. Nevertheless when grinding is required the ball ...

The inside of a cement kiln is an extremely challenging environment for making any kind of measurement. Temperatures are high, there is a lot of dust and tumbling clinker can damage in situ measuring instruments. Traditionally, singlepoint measurements have been made here using a ratio pyrometer with a peak picker algorithm, such as the Spot R100.
mill circuits. KHD's comflex grinding units are always engineered around a roller press as core grinding mill in close circuit with static and dynamic separators. Figure 1 and the equipment overview in Table 1 outline the new raw material grinding circuit in finish mode and the equipment chosen by SCCC and KHD. The grinding unit for SCCC uses two

This conclusion was drawn from a series of tests in which Portland cement was ground either conventionally in a ball mill or in highpressure grinding rolls. The water demand of the ball milled cement was 27 per cent and of the highpressure ground cement was per cent, at the same specific surface area (350 m 2 /kg).
