Low pressure drop Simple maintenance Cement grinding is a crucial stage of the flow sheet, where both cement quality and process e ciency are decided. Achieving the required fineness with maximum e ciency is down to the design of the ball mill and how well it runs.
The production process culminates in two ball mills. Each day, the 15meterlong machines grind up to 5000 metric tons of clinker the result is readytouse Portland cement. In each mill, two pinions and gear units transfer the force from two 2250kilowatt asynchronous motors to a girth gear that is directly connected to the ball mill surface.
A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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 Ball Mill. Feeding size: ≤25mm. Capacity: /h. Functional advantages: Uniform abrasive, low energy consumption.

Steel Ball Mills Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods ...
For a grinding plant designed for an output of 80 t of portland cement per hour a roller mill with a grinding bowl diameter of m is required. The total power consumption of the grinding plant is kWh/t, cor responding to a 20 % saving in comparison with a plant incorporating a ball mill.
Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing. Industrial ball mills can be as large as m (28 ft) in diameter with a 22 MW motor, drawing approximately % of the total world's power (see List of countries by electricity consumption). However, small versions of ball ...
AGICO cement ball mill is supported by static and dynamic bearings at both ends, greatly simplifying the support foundation and reducing the installation height; the mill can also be supported by static and dynamic pressure of single sliding shoe and double sliding shoe or by full static pressure.

This plant has 2 lines for cement production (5300 t/d). The ball mill has one component, m diameter, and m length with 240 t/h capacity (made by PSP Company from Přerov, Czechia). The mill's rotation speeds are mainly constant (14 rpm), and there is approximately a fixed oneyear period of changing liners.
suit all mill OEM's. Key benefits. Cement grinding. The feed for a cement grinding unit will normally be dry and. needs to be ground to a high degree of fineness. To achieve this efficiently, most mills will be split into two chambers. The first is set up for coarse grinding with a target to grind the feed materials down to around 1 mm.
Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 120mm according to different grinding requirements. In a cement ball mill, generally, φ50100mm steel balls are used in the coarse grinding chamber, φ2050mm steel balls are used in the fine grinding chamber. 2.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...
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 ...
