  • Moisture Removing & Increasing Efficiency in “Ball Mill”

    ball mill by grinding the raw bauxite and converting it to required fined grade. Calcined bauxite is used to make refractory bricks, abrasives and for steel polishing. Here I have discussed some issues with the ball mill grinding process like moisture content, its drawbacks on efficiencyRaw Material Drying-Grinding Cement Plant Optimization,Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can handle moisture about 8%. Fully air- swept mills (5-6M/sec) can dry up to 12-14% moisture.

  • Rawmill Wikipedia

    Occasionally, the mill is preceded by a hot-air-swept hammer mill which does most of the drying and produces millimetre-sized feed for the mill. Ball mills are rather inefficient, and typically require 10–20 kW·h of electric power to make a tonne of rawmix. The Aerofall mill What are the Differences Between Dry and Wet Type Ball Mill?,Aug 21, 2020· 3 Wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of dry ball mill. 4 The grinding particle size is fine and uniform, and the wet ball milling can not only grind agglomerate into fine particles, but also mix the lean material and the plastic material well.
