The cylinder length-diameter ratio of rod mill is generally 1.5-2.0, while the cylinder length-diameter ratio of ball mill is smaller, only slightly greater than 1. In addition, the cylinder speed of the rod mill is lower than that of the ball mill, so the grinding medium works in the cascading state. 2. Discharging way of ball mill and rod mill.A copper powder was milled in argon by a tumbler-ball mill to investigate the formation of copper coatings on ball surfaces and mill pot walls, which must be a significant process in mechanical alloying. Weight ratio of the coatings to an initial powder-filling was measured after milling at various ball- and powder-filling ratios.
Nov 18, 2008 We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill. 6. 1. Introduction Ball mill is an efficient tool for grinding many materials into fine powder.Ball mill filling ratio barkboats cz An inefficient ball mill is a costly weight on a range of cement plant kpis from the bottom line to the environmental footprint and the quality of product. getting the ball mill right is therefore vital to ensuring a plant is as productive and profitable as .
Ball mill is one of the common equipment in mineral processing equipment. The reasonable ball loading of ball mill not only affects the grinding efficiency and productivity improvement, but also relates to the service life of ball mill.Therefore, it is very important to master the reasonable amount and the proportion of ball loading in ball mill.Effect of speed in ball milling effect of speed in ball milling (PDF) Effect of ball mill grinding parameters.

Generally, the filling rate of ball mill is 40 – 50 , and that of rod mill is 35 – 45 . 5. Fineness of Product. The discharging fineness of the material milled by ball mill is between 0.074-0.4mm, and that of the material milled by rod mill is between 0.833-0.147mm. 6. Running Cost.The problem of the proportion of the steel ball and the ball mill-Oriental Casting and Forging .-The problem of the ratio of the ball mill is a problem that often plagues people. The rationality of the formulation directly affects the production efficiency of the ball mill, and also affects the production quality of the ball mill to a certain extent.
In the grinding operation, the consumption of steel ball is very large, which is about 10 times than the loss of ball mill liner. In order to make up for the loss of steel ball and keep the size of the steel ball unchanged in the ball mill machine, it is necessary to add the steel ball regularly according to a certain ratio.Calculate the reduction ratio of ball mill of 40 the actual ball volume is considered to be 2124 of the empty mill Now in order to get an efficient milling action 80110 of the pores in the ball bed must be filled with the actual particles to be ground.
