20111028&ensp·&enspC. BALL MILL SLAKERS Ball mill slakers are an adaptation of ball mills, which originally were designed for wet and dry grinding, to lime slaking. Two types of ball mills are used for slaking, horizontal and vertical. Ball mill slakers are generally used where: the capacity required is too large for other types of slakers.

20171121&ensp·&enspThe output of the mill depends on the horsepower of the motor, the type of feed being ground, and the size of the screen mesh. For example, a 50 HP hammermill will fine grind about two tons/hour of maize or about 4 tons/hour to a coarser particle size.
2009827&ensp·&enspmilling circuit consists of a rod mill followed by a ball mill in series. Crusher product (9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is

201089&ensp·&enspA Tutorial on motor torque calculations A question oft asked on MYCNCUK is "how big a motor do I need?". There is no simple answer to this, and the options are usually: a) follow someone elses build and copy theirs b) take a guess and try again if you are wrong or c) work it out, which is the subject of this tutorial. When choosing a motor you need to know: a) what power and torque output is
FEED RATE – When cutting woods on a STEPCRAFT, I always suggest setting this to 1/2 of the maximum machine feed speed. So for a Version 1 machine, this will be set to 15 mm/sec and for a version 2 machine, you will set this to 25 mm/sec. Once the job is running you can increase this feed rate by adjusting the F actin UCCNC. When you reach 200

Thisis what a proposed based on literture review i did and others agree its more and less correct. But remember it all depends on your mill feed size after pregrinding.
