The ball mills crushed 78 tons per day and, after classification, the coarser part of this, amounting to 38 tons, was ground to about 250 mesh in the tube mill. The pulp fed into the mill contained: coarser than 40 mesh, per cent.; 40 to 60 mesh, per cent.; 60 to 100 mesh, per cent.; 100 to 150 mesh, 7'6 per cent.

THEORY. As shown in Figure, a bubbler tube is immersed to the bottom of the vessel in which the liquid level is to be measured. A gas (called purge gas) is allowed to pass through the bubbler tube. Consider that the tank is empty. In this case, the gas will escape freely at the end of the tube and therefore the gas pressure inside the bubbler ...

Operating principle of the coal mill. Fig. 1 shows the structure of a duplex inlet and outlet ball mill. The system is equivalent to two parallel cylinders joined together in one ball mill to achieve high milling efficiency. Milling work is carried out by the collision, squeezing and grinding of the steel balls inside the mill.
