Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as; πΆπΆ3 = 2.44 π·π· 0.2 (3) However, it is important to note that C3 =0.914 vessel used in producing the ball mill was got from a

Get Price### Grinding in Ball Mills: Modeling and Process Control

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The

Ball mills tumble iron or steel balls with the ore. The balls are initially 5β10 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.

PRINCIPLE: A ball mill works on the principle of impact and attrition. size reduction is done by impact as the balls drop from near the top of the shell. 7. CONSTRUCTION: Wet or dry ball mill grinding machine consists of following parts: 1. Feeding part 2. Discharging part 3. Turning and driving part( gear, motor etc) 4. Rotating balls 8.
