Fine Grinding and Mill Cooling. PROBLEM. Insufficient mill cooling lead to material agglomeration on balls and liners. The grinding is not any more done by balls against material but by material against material. SOLUTION. Adapted mill cooling, playing with:-Clinker temperature-Mill ventilation-Water injection

The …
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
• Raw coal is ground in a coal mill (VRM/ball mill) to fine coal or pulverized coal. • The hot materials coming out of the kiln are known as clinker. • Clinker is in the form of nodules of various sizes, usually 1-25 mm in diameter. • The hot clinker nodules are cooled to about 100 – 120oC in the cooler attached to the kiln.
