Combined roller and bowl type mills

We supply roller and bowl type mills or complete milling lines with a single unit capacity from 2 to 450 t/h. The milling lines include systems for transporting and feeding the product to the mill, weighing system, pneumatic system for receiving the milled product, dedusting and screening plants. The offered solutions are operated in hundreds of industrial plants throughout the world, in particular in the production of cement, clinker, ceramic semi-finished products, kaolin, bentonite, coal, coke, dolomite, talcum, anhydrite, calcite and limestone.

Vertical roller and bowl type mills are characterised by a number of advantages, including above all the capability of carrying out the process of milling, drying and separating in one device. The offered solution is additionally characterized by ease of changing the grain size of the milled product, low energy consumption, quick replacement of wearing parts, the ability to select the classifier to suit the specific process, low noise emission.

Advantages of vertical (roller and bowl type) mills

  • Milling, drying and separation in one machine
  • Low energy consumption
  • Easily change the grain size of the product after milling
  • Quick replacement of wearing parts
  • Possibility to select a separator according to the nature of the process
  • Low noise emission

Vertical roller and bowl type mills – application

Mills of this type are mainly intended for milling products of natural origin. However, they can also be used for less typical applications, such as glass cullet. Their capacity ranges from a few tonnes of product per hour to 450 t/h.

Application of vertical mills by industries:

  • mineral and ore purification industry
  • cement industry
  • energy industry
  • building materials industry

Application of impact mills by products:

  • limestone
  • ceramic semi-finished products
  • slag
  • coal and coke
  • bentonite
  • colemanite
  • anhydrite
  • kaolin
  • cement
  • talcum
  • calcite
  • dolomite
  • coal and biomass

  Designing installations for bulk materials

Depending on the investor’s needs, we are able to provide a single device, as well as design and then build a complete installation for bulk materials. In addition, we design and production dedusting and central vacuum systems (including those for explosive dust).

  Explosion safety

Due to over 25 years of experience in the field of explosion safety, if installation will process flammable or explosive dusts, we are able to make appropriate systems to protect against the effects of an explosion and studies required by law (including explosion risk assessment, determining of explosion hazard zones, explosion protection document).
