Application fields

CIMMA pendular roller mills are used in hundreds of plants producing ceramic pressed tiles (gres, single fired, double fired), extruded floor tiles, klinker, roof tiles, flower pots. Inert raw materials can be ground mixed with clays.
The requested granulometry is easily obtained with the proper choice and regulation of the air classifier. Screening of the product is usually not necessary.
The ceramic bodies prepared with Pendular Roller Mills provide ceramic products with high mechanical properties and very smooth surface, free from defects. Clays with moisture up to 10÷12% are easily processed at full capacity and competitive cost with the introduction of hot gas through the mill.
The ROLLER MILL can operate in closed circulation of inert gas, controlled by suitable safety equipment.
In these conditions the Roller Mill can process materials, such as sulfur, subject to explosion when in contact with standard air.
These kind of mills are suitable for fine grinding of chemical products and minerals of medium hardness and abrasiveness.
Product fineness adjustable in the range 20÷400 micron (with dynamic classifier).
Production of FILLER of different minerals (0÷100 micron) with dry-grinding.

Low specific production cost, due to:

  • Low energy consumption
  • Reliable operation
  • Automatic control
  • Grinding bodies (grinding ring and rolls) in wear resistant alloys
  • Efficient drying by blowing hot gas through the mill
  • Dust free operation in open or closed air circuit depending on specific application

Capacity range 5÷20 ton/hour.
