Mar 19, 2017 . Ball Mill Crushing by tube-mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30-mesh other types of crushing machinery were not efficient. In order to crush with one pass, these mills were made 18 to 22 ft. (5.5 to 6.7 m.) in length. Pebbles.
Mill (grinding) - Wikipedia
Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding.

The determination of the efficiency of the milling process - SAIMM
materials tested were also comminuted in a ball mill under optimum conditions. There are indications that slow crushing under stiff conditions is the most efficient method of breakage that can be devised. The com- parison with ball milling results thus yields a value for the efficiency of ball milling of approximately. 80 per cent.

CUSHIONING EFFECT IN BALL-MILLING - J-Stage
A laboratory investigation of ball-milling with special reference to cushioning effect was carried out by the author. Cushioning effect in the mill is an unknown matter, but interesting for mill engineer. When a ball falls from the top to the are bed, the latter acts as a cushion on the former, and some crushing energy of the ball will.
