Advantages

Raw mill absorbs large tube mill in recent years in the design, manufacture, installation, operation and maintenance and other aspects of experience, the technical structure and various aspects such as material selection, the bold innovation and improvement. Make the grinding machine structure is simple, safe and reliable, light weight, cover an area of an area small, building saving investment and high grinding efficiency. Raw mill changed the original mill structure, make the body, chassis integration, installation time can be a and based on the plane, main bearing adopts double row spherical roller bearings, can reduce energy consumption by 30%, improve the fine-grained, deal with 15 ~ 20% increase in energy.

Features

  • 1. The raw mill allows into the grinding material composite water up to 4 ~ 5%, the grinding raw water of < 1%.
  • 2. Pieces for high yield production technology in the raw mill grinding water large grinding machine is used when the output is low, modification effect obviously, from up to 30 ~ 50%, 5% power saving effect of 0 ~ 1, raw meal fineness more than 0.2 mm square hole sieve sieve & lt; 0.5%, improve the quality of raw materials.
  • 3. After using the technology to reform, not only can ensure the quality of the production of cement production line, but also can use parity electricity price and electricity to adjust production, achieve saving energy and reducing consumption.
  • 4. Reasonable design line to minimize the system resistance, ensure smooth line, avoid dust, pipe insulation, at the same time should do well in system to prevent dewing dust collecting system.
  • 5. Mixer strict operating system to ensure that the phase equilibrium system drying ability and grinding ability, strengthen the system lock the wind, grinding control tail exhaust temperature > 65. C, make sure you use effect.
