  • Coal surge bin level measurement, point level detection

    In a typical coal power plant, lignite (soft coal) and anthracite (hard coal) are stored temporarily in bins up to 15 meters high. To ensure that the coal belts are continuously loaded without interruption, a robust and reliable level measuring system is required. Additional point level detectors are used to prevent any overfilling of the bins.

  • Exploring ball size distribution in coal grinding mills

    5/1/2014· It has been shown that mill capacity is linearly correlated to media surface area, thus using 30 mm balls as top size which leads to a fine ball size distribution in the mill is evidently a better approach than the current approach of using larger ball sizes. However the fact that the coal feed to this plant is known to be contaminated with a

  • Mill Steam Inerting System Review and Performance Validation

    The mill system consists of coal feeders, crusher dryers, stand-alone centrifugal static classifiers and a ball tube mill. Raw coal from the feeders is mixed with hot primary air and then fed to crusher dryers. After primary crushing and initial drying with the crushers, the crushed coal is fed into the mill for pulverization. The pulverized coal from the mill is air

    Coarseness is expressed as the percentage retained on a 50‐mesh screen (297 μm). Typical recommended value of pulverised fuel fineness through 200 mesh sieve is 70% and 1% retention on 50 mesh sieve. The standard method of testing is to withdraw a sample from the pipes feeding the burner and run the sample through a series of sieves.
