Raw material ball mill, also called raw meal ball mill, is important grinding equipment in cement production process After being crushed, the raw meal enters the raw material mill The raw meal is grinded into fine powder by the motion and squeezing of steel balls The raw material mill manufactured by Great Wall Machinery can meet the raw material supply of 250~2500t d
The raw mix and required additives are fed from their bins to the raw mill via blowers for drying and grinding. The raw mill contains two chambers - a drying chamber and a grinding chamber. Hot gases coming from a preheater/ kiln system enters the mill and dries the raw mix materials before it enters the next chamber, which is the grinding chamber.

Raw Meal Ball Mill Great Wall. Raw Meal Ball Mill is mainly used in grinding raw materials and final products in cement plant. It is also suitable for grinding various ores and other materials in the metallurgy, mine, chemical, construction and other industries.
From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below 0.75 mm), followed by a tube mill for fine grinding. Typically the ball mill was placed on an upper floor so that material could move by gravity.
The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured.
Raw material mill, also called raw meal mill, is important grinding equipment in cement production process. After being crushed, the raw meal enters the raw material mill. The raw meal is grinded into fine powder by the motion and squeezing of steel balls.
The ball mill was simulated as a single compartment mill by eliminating the mill length of 2.935 m which was used in drying stage, such that the full length (L = 9.87 m) of the mill was used in grinding. Thus, drying of the raw meal outside the mill by an appropriate dryer was assumed.
Ball mills are rather inefficient, and typically require 10–20 kW·h of electric power to make a tonne of rawmix. The Aerofall mill is sometimes used for pre-grinding large wet feeds. It is a short, large-diameter semi-autogenous mill, typically containing 15% by volume of very large (130 mm) grinding balls.
