Ball Mill Working Principle Center drive and side drive are two common drive modes for a ball mill. Center drive grinding mill means the motor shaft extends along the axis of mill body while side drive has a motor located on the side of the mill and torque is transmitted via the large girth gear which is bolted on the flange of the mill body.
The ball mill was initially charged with the grinding media and the feed material. The mill was then running for a definite interval of time, and the torque was recorded during this period. After each grinding period, the mill was stopped, the balls were removed from the mill and mixed powder samples were withdrawn for fineness analysis. 3.1.
The grinding chamber contains a certain quantity of ball charge in a different sizes ranging from 30mm to 90mm. The hot gas and grinding materials mill outlet feeds to a separator which separates fine and course product. The latter, called reject, is sent to the mill inlet via an air slide for regrinding.
Ball mill is mainly used in the grinding of finished products and raw materials in cement plants.

Stage grinding which is by repeated passes followed by removal of the finished material, is the best means of obtaining selective grinding. These terms must not be confused with differential grinding, which has to do with the relative grinding rates of two or more minerals in an ore. Rod Mills = Selective Grinding. Ball Mills = Non-Selective ...

History. Early hydraulic cements, such as those of James Parker, James Frost and Joseph Aspdin were relatively soft and readily ground by the primitive technology of the day, using flat millstones.The emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material.

Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.
Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].
Dec 26, 2017· Several factors affect the efficiency of a ball mill for cement grinding. In this article, we shall be looking at some of these factors that have been proven to influence grinding efficiency: Mill Geometry And Speed. According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Cement mill has features of high adaptability to raw materials, continuous production and big grinding rate. Cement ball mill can produce powder from various non-flammable and non-explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%, such as barite, limestone, kaolnite, ceram and slags, etc.
Cement manufacturing - brief description of a 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.
