Besides cement a variety of other materials are being ground in tube mills such as raw meal, coal etc. 3.2 Number of chambers A modern cement mill can consist of two or one chamber. Raw material mills are often equipped with one drying compartment to evaporate the water contained in the raw material and one or two grinding chambers.

Cement grinding is accomplished by 2 finish mills. A-mill is a 9'6" x 30', 1250hp, 2 compartment mill supplied by FL Smidth. It has a rated capacity of 30 stph. B-mill is a 12' x 36', 3000 hp, 2 compartment mill supplied by Fuller-Traylor. B-Mill is fed by a 1,000 HP pre-grinder mill and has a rated capacity of 70 stph. Quality Control

In our two-compartment cement mills, the first compartment (for coarse grinding) has a step lining suitable for large grinding media. It protects the shell while ensuring optimum lifting of the mill charge. In the second compartment (and also in our one-compartment cement mills) we use a corrugated lining designed to obtain the maximum power ...

Cement ball mill is not only suitable for over-flow grinding, but also applicable for cyclic close-flow grinding together with powder collector. There are two ways of grinding: the dry way and the wet way. Features 1. Can work with grinding and drying equipment simultaneously. 2. Easy to adjust the fineness of grinding products. 3.

Modelling and simulation studies were carried out at 26 cement clinker grinding circuits including tube mills, air In developing a model toi nmlti-compartment ball mills, samples were taken from streams around the circuit, the mills . the effect of classifying liners can be implemented into the model structure.

of the second compartment. The finish-ground material is mechanically discharged via a discharge diaphragm. The two-compartment separator mill is indispensable in cement grinding – and not only that: this type of mill is also ideal for other dry, brittle materials such as …

Request for feedback for a Two Chamber Cement Mill Ball Charge and Longitudinal Sieve Analysis. I am looking to get feedback for the following cement mill for a white cement plant. The first compartment has lifting liners and the second compartment has lifting at the beginning followed by classifying liner. The mill dimension is as follows:

How our cement ball mill work. Our cement ball mill grinds cement clinker, gypsum and similar materials of moderate moisture content in a one compartment or two compartment systems. As the crushing compartments rotate, the balls inside them grind the clinker. Ball size determines finished product fineness.

Main mill drive for a cement plant - MENZEL Elektromotoren. Customer: Cement plant From an African cement plant Menzel received the order to supply a interchangeable motor to the existing main mill drive. In fact the customer bought already another interchangeable Menzel motor; he confided these complex tasks to the Menzel specialists.
