work of ball mill pdf

Ball mill - WikipediaA ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It 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.

About efficiency of mill work the parameters of work decide, like rotary speed, load, grinding medium contents, sort of grinding medium and its size and parameters of the feed being comminuted what means particle.

Ball mill - Orto Alresa

The ball mill splits the sample because of the hits against the balls. It moves along an arc of a semi-circle due to the dragging of the pitcher in the cylinder motor. Isolated jars prevent the contamination of samples. Its function and design makes it suitable for mill works in laboratories of public works, manufacture of paints,.

milling time plays very important role. During this process, wet or dry milling condition is adopted. The decreasing of particles size depends on the powder-to-ball weight ratio. Fig.1. Commercial Ball Mill image. Figure is adapted from [11]. Ball mill image is shown in Fig.1. Ball mills are the main equipment in grinding industry.

effect of operational variables on ball milling - Poli Monografias - UFRJ

This work consisted on experimental batch grinding tests with a 30 x 30 cm ball mill in which operational variables were altered. The change of these parameters resulted in direct variation on the final product size as well as on the average power consumption. Therefore, it was possible to verify enhanced process efficiency.
