A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell ...
Many advances in vertical roller mill technology have been made, due to the adoption of this milling system for clinker and slag grinding as well as production of pozzolanic blended cements. 4. Vertical Roller Mills have gaining more popularity in new projects due to possible 40% less energy consumption than ball mills. 9
To optimize the energy consumption of the mill, Siemens has developed a new mill control system. The first pilot project involved one of the four ball mills at the Rohrdorf plant. Dating from 1965, this mill consists of two chambers: the first chamber is filled with large steel balls, and the second with smaller balls.

GEAR & DRIVE TECHNOLOGY this option is reduced operating costs and perhaps greater product output over the life of the new mills. The repair option is only a temporary solution because it is virtually impossible to anneal the material and reduce the heat-affected-zone when the trunnion is welded in-place.
Five years later, the first Christian Pfeiffer mill diaphragms were registered for patent approval. In 1939, the Heyd separator technology was established on the European market. Another milestone followed in 1960, with the development of the first diaphragms for ball mills with a diameter of 5 m.
The seven new vertical roller mills are intended to replace existing ball mills. At the Pinarhisar works an MPS 4000 B vertical roller mill will be used for grinding 250tph of cement raw material to a product fineness of <12 per cent R on 90µm at an installed power of 2000kW. Due to the high mo...
Typical types of mill used in ore beneficiation are autogenous (AG) and semi-autogenous (SAG) mills together with ball mills to, for example, obtain particle sizes smaller than 100 µm. One process variation that has become increasingly established in recent years is the combination of AG or SAG mill with a ball mill and a downstream agitated ...
Pfeiffer SE, was recently contracted to supply a complete grinding unit to replace aging ball mills at the Hormicreto clinker plant in Ecuador. The new grinding unit helps reduce energy consumption and improves the overall grinding efficiency, allowing the plant to increase production from a single mill. Gebr. Pfeiffer supplied the following ...
Traditionally, ball mills are used in cement industry for raw material, fuel and product grinding. Ball mills use an established technology and offer certain advantages. However, they have higher energy demands. By using an appropriate kind of the more efficient roller mill technologies – either as a replacement or in combination with ball mills – considerable energy savings can …

The three main mill options for phosphate ore are: Ring-roller mills: Vertical rollers rotate inside a fixed horizontal ring (Figure 1). Material fed between the rollers and the ring is ground to powder. Ball mills: A horizontal rotating cylinder contains a charge of steel balls. These balls tumble as the mill turns so that material caught ...
In contrast, ball mills result in narrower distributions, less specific surface and lower yield values 4. An example is shown in Figure 1 . Physically measurable properties of chocolate masses, like flow attributes or hardness, are correlated to sensory perceptions such as snap, hardness, melting and the like.
