If the coarse feed size is reduced, the circuit efficiency will approach that of the stage-crush and ball mill circuit. Hence, if the JKDropWeight test Axb parameters (a measure of rock competency) are less than about 40, then secondary crushing is worth considering.

A ball mill is a type of grinder.It is a cylindrical device used in grinding or mixing materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
(the steel thickness is generally 1/100 of the cylinder diameter, for example ball mill of Φ1500, the steel plate thickness is 16 mm), the material of inlet and outlet hollow shaft is ZG35. 6. The hollow axis adopts the cast steel and the lining can replace, the rotating big gear processes in the way of casting rolling gear.
determined by 0.0254 Wh/rev (difference between 0.1331 and 0.1077) or 91.44 Ws/rev. This is equivalent to a power draw of 106. 76 W for the mill with ore …
The level of vertical roller mill output not only affects the production schedule and goals, but also affects energy consumption, enterprise costs and benefits.

25 Introduction of Stone ball mill: Suitable for grinding material with high hardness. The shape of the final products is circular. No pollution for the powder with ceramic ball. Stable performance. Easy installation. The capacity and fineness can be adjusted by adjusting the diameter of the ball. Working principle of Stone ball mill:
the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Answer (1 of 2): Stone grinding machine is a kind of mining equipment,which is used to grinding stone lump(pls note:not large stone! Generally we need stone crusher to crush large stone to small pieces at first) to stone powder. The main types of stone grinding machines: 1. …
For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
This was dug out of my grandads garden (Romford, London) in the 1960s. The circumference is ~25CM. I assume it is stone. The suggestions that I've had so far are that it could have been from a ball mill perhaps, a bocce ball, a cannonball or a paper weight (even if it was used as a paperweight it may not have been made for that purpose).
All aspects of crushing, ore conveying and screening operation and maintenance: Discuss any type of crushers: gyratory, jaw, cone, roll, HPGR, impact, hammer, etc. Crusher liner, lubrication, mantle, bowl, spider and all other components.Ore transportation on conveyor belts and through classification systems such as vibrating screens, grizzlies and feeders.
