how to estimate the wear rate for Ball mill
Dec 08, 2009Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL
The mill is designed to handle a total ball charge of 324.5 t at loading with a percentage filling of 29.5% in both the chambers. Both the chambers of the cement mill were charged with 80% of the designed charge, which works out to 86 t in Ist chamber and 172 t in the IInd chamber.

Rod Mill Design Calculations
EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced. The inefficiency factors for open circuit

Cement Grinding Optimization
Jul 31, 2014The "work horse" of the cement grinding plant is the twocompartment ball mill, commonly called the tube mill. Significant advances in model development were achieved in recent years (Benzer et al, 2001, 2003) through research on industrial scale.

Tube Mills
They crush minerals, ores, coal, or cement clinker by impact and friction until the material is pulverized. The tube mills, which can have a diameter of up to 15 m and a length of up to 20 m, are installed horizontally. With tube mills, a distinction is made between different drive variants. FLENDER particularly specializes in: Single pinion drives

Cement Mill
The first compartment is lined with lifter plates, large grinding media for coarse grinding and special lines ensures optimum lifting of the mill charge. The size distribution of the grinding media in the coarse grinding compartment is designed for the coarsest particles in the mill feed material and to ensure adequate fineness of the material

Autogenous mill and semi
While AG mills operate without a ball charge, SAG mills use a grinding media charge of normally 3 %  12 % for comminuting the feed material. The maximum feed size is between 200 mm and 500 mm. The AG/SAG mill is normally installed upstream of a tube mill operating in closed circuit with hydrocyclones.
