Jul 04, 2020 The major raw material for cement production is limestone. The limestone most suitable for cement production must have some ingredients in specified quantities i.e., calcium carbonates, silica, alumina, iron, etc. Typically, cement plant locations are based upon the availability of good quality limestone in the vicinity.
The three-fan system consisting of preheater fan, raw material fan and kiln exhaust fan makes the system operation control convenient and flexible, and easy to produce stably. How to Filter out Metal Matter Damage. The mixed raw materials from batching station are fed into the raw material mill by a belt conveyor and a lock air feeder.
In the wet process, water is usually added to the raw mix to form the slurry. While in the dry process, raw mix is the fine powders after grinding and drying. The selection of process is mainly based on the nature of raw materials. When their moisture content is than 20 , the wet process will be preferred.
Nov 04, 2019 Control is accomplished by applying a combination of predictive controls and pulp-tracking techniques to reduce variability. Pulp tracking is a concept that can track the performance of various key pulp properties through the process, such as moisture content in wood chips, pulp conductivity in brown stock washers, or chemical dosage in the first stage of bleaching.
In this unit, the proportioned raw materials are being ground to the size of (10 residual on 90 μm sieve) by closed circuit ball mill in line 1 and Vertical Roller Mill (VRM) in Line 2. While grinding the raw materials are being dried from 4 moisture content to 1 using the excess hot gas emitted from pyrporocessing system.
