MVR mills need only few peripheral machinery, no or little walled-in space, their operation is dust-free and they have a low noise level. Low electric energy consumption The grinding principle and the high efficiency classifier ensure the reduction of electric energy consumption by up to 40 as compared with conventional ball mills.
UMS mills. 1.2 Principle of Operation In ball mill, ball has to be charged around 30-32 in first and second compartments. Balls are in the range of 50-90mm in coarse and 15-50mm in fine grinding. Grinding of material takes place by means of collision or attrition or tumbling action takes place between the balls and the charge.
Ball mills are the classic grinding plants Around the world they are the most common installations. Ball mills convince thanks to their simple principle and low maintenance needs They are robust, durable and extremely reliable in operation. By using ball mills in closed circuit with a separator, their efficiency can be increased even further.

Separator Functional Principle. The separator, or disc centrifuge, is a vertically arranged centrifuge. It is used for separating and clarifying liquids. In a disk stack separator, solid-liquid mixtures or liquid-liquid mixtures are separated by centrifugal force.
Separators have been part of Christian Pfeiffers portfolio since 1939 and are part of the core portfolio. The first separator was invented at Christian Pfeiffer by engineer Jakob Heyd and has been continuously further developed. Today, the QDK high-performance separator is widely used in the cement industry. Process-driven approaches
Flotation Separation Line. The flotation separation line also called the flotation separation process, flotation plant, flotation line, flotation separation plant or flotation mineral processing line is a whole set of equipment completing the flotation separation process with the flotation separator as its core device.
Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.
Cyclone Preheater Introduction The cyclone preheater is the core equipment of the new dry process cement production technology.It uses the suspension preheating method to preheat and partially decompose the raw material to shorten the length of the rotary kiln, and at the same time make the raw material and the hot gas flow in the kiln full.
Theses 3 types of hoists can be selected according to the following 1, whether the material is in the form of powder or granules or small pieces 2, whether the material has abrasiveness, adsorption or viscosity, whether it contains water. 3, the specific gravity of the material and the amount of delivery per unit time.
