Mills

CEMTEC's mills come in many different designs, sizes, and capacities. Every machine is tailored to the individual client's needs. The designs and sizes of CEMTEC's mills and grinding plants depend on the raw material used and the desired product properties. CEMTEC's technical personnel has the relevant know-how and all technical aids and tools to develop the perfect solution in close cooperation with the client.

At CEMTEC's pilot plant and laboratory, the parameters for every individual application can be checked. With such a pilot plant test, CEMTEC can guarantee its clients that the selected solution meets their requirements and that the treatment plants chosen match the conditions needed.


Mills

Cement mills

Double chamber ball mills for the cement industry come in various designs: For bearings, either slide or slide shoe bearings can be chosen. Possible drives include gear rim/pinion, lateral, or central drives. If the processing material is wet, cement mills can also be equipped with a drying chamber. The drying chamber can be integrated into the mill or flange-mounted to it. It is equally simple to design the mill shell in one piece or in several parts (for transport reasons).

Ball mills for wet and dry grinding applications 

CEMTEC offers grinding solutions with ball or pebble mills for wet or dry applications with an open or a closed grinding circuit. The mills are available with either a slide, slide shoe, or spherical roller bearing, as well as with either gear rim/pinion, direct, or central drive; they can have a rubber, steel, or ceramic lining. Moreover, different loading and unloading devices are available.

Rod mills for wet and dry grinding applications 

CEMTEC provides grinding solutions with rod mills for wet and dry grinding applications. These mills are available with either a slide, slide shoe, or spherical roller bearing, as well as with either gear rim/pinion, direct, or central drive; they can have a rubber or steel lining. Moreover, different loading and unloading devices are available.

Autogenous (AG) and semi-autogenous (SAG) mills

Fully autogenous and semi-autogenous mills as aggregates can be used to pregrind minerals and ores and to grind waste, e.g., bulky waste.
AG and SAG mills can be designed for dry or wet grinding. The bearings are hydrostatic slide or slide shoe bearings. Usually, AG and SAG mills have a gear rim/pinion or direct drive. Our product portfolio includes sizes from a laboratory scale to a diameter of 10 meters or more. For transport reasons, these mills consist of several flanged parts.

Grinding plants

Our entire range of plant construction services is adapted to cement, building materials and processing technology. Therefore, we not only offer supply, transport, and erection of such plants, but also extensive specialist process know-how. Our services cover anything from expert consultation to engineering services and execution of turnkey plants such as:

  • Turnkey raw meal and cement plants including raw material handling, storage, and packing plants
  • Turnkey limestone wet grinding mills to produce limestone suspension for flue gas desulfurization plants
  • Turnkey processing plants for the building material, filler, recycling, fertilizer, and chemical industries
  • Turnkey drying plants 
  • Turnkey mills for the mining sector for throughputs up to 1,500 tph and finenesses from a feed size of 300 mm to a product size of 80% < 40 µm

Vertical roller mills

CEMTEC's completely new and innovative vertical roller mill constitutes one more step toward more efficient grinding of soft and medium-hard products. It combines well-established technical characteristics with a new, innovative support and drive system. This new system means that the forces generated during grinding are retained in the mill structure instead of being conducted to the foundations. This makes the civil engineering work more cost-effective.

Vertical roller mills are suitable for plant capacities between 2 tph and 40 tph, with product sizes ranging between 100% < 10 µm and coarse products with 100% < 500 µm.

Laboratory mills

CEMTEC's product range also includes various kinds of horizontal and vertical laboratory mills. These mills are used to establish the specific energy  (in kWh/t) required for grinding minerals and bulk materials.
