More efficient grinding processes

Overview of all of our mills

Mills for grinding cement, coal, or minerals: Christian Pfeiffer designs and builds grinding plants for many different feed materials and finished products. Our mills are as varied as the requirements of our customers. Ball mills, vertical mills, compact mills, jet mills or roller mills? Our employees are experts in the field of grinding plants, and they analyze for you just which mill will provide you with the most efficient production process possible. 

Ball mills

Solid, reliable and durable

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.

Compact mills

The ideal solution for smaller product quantities

The compact mill is convincing due to its compact dimensions. This enables it to be flexibly integrated into existing structures. With a maximum diameter of 2.8 m, and maximum length of 7 m, it is especially suitable for the production of small quantities of finished products. The compact mill proves itself both in dry and wet grinding, and can be operated with or without a separator.

Roller press

For raw meal or for pre-grinding in two-step grinding processes

The roller press is often used where energy-efficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles (microscopic cracks), so that the subsequent fine grinding is easier. When used as a pre-grinding system in ball mill circuits, production increases of up to 100% and more can be achieved.

Vertical mills

Flexible mills with integrated separator

The vertical mill enables high energy economy, and convinces with low specific wear values. Drying of the feed material, grinding, separating, and material transport take place inside the mill. It is thus especially well suited for grinding products with high proportions of wet components.

Jet mills
For ultrafine finished products

The jet mill is popular everywhere where the special fineness of the finished product is important, for example in the grinding of minerals for low to medium hardness (mohs 1 to 4). This extremely energy-efficient mill works reliably and precisely. The integrated separator ensures a guaranteed fine top cut of up to 1 µm.
