A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners
The rotary kiln is the heart of a cement manufacturing plant. Cement kilns have all chemical ingredients. These. ingredients are at a broad range of gas temperatures from 100° to 1650°C. The emissions contain: High concentrations of alkaline solids, including sodium and potassium oxides; High concentrations of freshly created Calcium Oxide.
Since the pressure drop in rotary drum filters when dirty can be as high as 30 mm w.g, the return air fan selection in mill humidification applications should account for up to 25 mm w.g. pressure drop in air filters and the return air fan selection and motor kilowatt should cater to the required return air flow rate against a total static ...

1. Introduction. Cement is an energy-intensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent years, the production …
Cement Silo. Common Issue: Coating in cement Silo. It happens due to storage of cement in silos at high temperature (>70 o C), and improper water spray system in cement mill. Strategy to fix the issue: Use cement coolers if cement temperature is higher than specified. Do not store cement for long time in silo.

However, this does not mean there are no opportunities for optimisation. The gas flow and velocities through the different parts of the VRM have a critical impact on the external recirculation of materials, the pressure loss across the mill and the electricity consumed by the mill induced draught fan.
In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent.

Mainly in USA, the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH .Normal range of cirulating load in a conventional close circuit ball mill is around 100-200%.
Batch mixers enable you to mix cement slurries and other fluids and feature two centrifugal pumps for delivering fluid to high-pressure pumps, recirculating cement slurries for mixing in blending tanks, and transferring fluids from remote tanks.
The mill is equipped with an external material recirculation allowing the reduction of pressure loss in the mill. It can also be used for emptying the mill in case of maintenance. Our products for cement raw material preparation

The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. If your product size needed is passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again.

A typical general purpose Portland cement of fineness (specific surface) 340 m².kg-1 ground on an efficient closed-circuit ball mill system requires around 32 kWh per tonne, so a 10 MW mill would produce 313 tonnes of this per hour. In addition to the energy consumption of the mill, the "ancillary" equipment (separator, fans, conveyors, pumps ...
The principle of the new generation of vertical mill was to direct higher pressure from the grinding element to the material bed using hydraulic systems. From this approach the roller press, CKP (pre-grind vertical rollers) and Horomill ™ all developed. Raw milling. The gas-swept vertical mill quickly became the raw mill of choice.
