Ball Mill Brief Introduction of Ball Mill. Ball mill is the key equipment for grinding after the crushing process in the beneficiation plant, it is used to grind kinds of materials such as copper ore, gold ore, magnetite ore, quartz, lead zinc ore, feldspar and other materials into fine powder 20-75 micrometer.
Description. GTEK XMB series rod ball mill is an efficient laboratory grinding equipment for wet grinding of ore or other materials.Steel balls can be used as grinding medium instead of steel rods. In rod grinding operation, particle sizes of final product are relatively uniform and ore overgrinding can be eliminated. Generally speaking, lab rod mill is commonly …
The characteristics of the rod mill are that the product is relatively rough. Still, the particle size is uniform, containing less coarse sand and sludge, and the over-grinding is lighter. The discharge particle size is usually between 0.833~0.147mm, and the particle size characteristics of the rod mill product differ from those of the rod mill.
In this article, we present laboratory scale batch grinding and leaching profiles of a mono-sized gold ore sample (-1700 + 850 μm). The sample was obtained from a run-of-mine (ROM) ore...
Rod Mills are designed to grind coarse materials like limestone, potash, coal, phosphate and bauxite in low tonnage operations. They are available in multiple diameters, wet or …

2. A wet rod mill was loaded to 45% of its volume with a charge consisting of a gold ore and steel rods. The rod diameter was 70 mm. the mill has inner diameter of 1980 mm and was rotated at 21 rpm with a rod load of 23.8 t. The rock volume was 0.4 times the rod volume after taking into the account the porosity of bed.

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.
EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
