The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
The combination crusher is a new generation high efficiency crushing machine designed and researched by integrating the domestic and foreign crusher technology with the same kinds and optimizing the main technical parameters.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.

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 toball mills(dry basis) is typically 75 vol -% ore and 25% steel Theball millis operated in closed circuit with a …Learn More
Themill(with 30 cm in diameter and 30 cm in length) and the test conditions are standardized, with a maximumball sizeof 40 mm and an ore top size of 3.35 mm. With less than 300balls, it poses no challenge in running the simulations, if only grinding media are included. For such asmall mill, one could also include the ore or powder charge.Learn More

1. Introduction. Theball sizeis one of the critical factors for determining themillperformanceof ball mills. It is well known that larger balls are needed for the effective breakage of large-sizeparticles, whereas smaller balls are more effective for the breakage of fine particles.Learn More
Ball Millsare generally used to grind material 1/4 inch and finer, down to the particlesizeof 20 to 75 microns. To achieve a reasonable efficiency withball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into themillto be reduced.Learn More
