The aim of this paper is to show how fragmentation optimisation has yielded positive results at all stages of the production chain from the mine to the mill passing through an impact hammer crusher a rod mill and ball mill operating in close circuit with hydrocyclones.
The application and advantages of rod mill: the discharging granularity of rod mill is evener and the output is higherIt is widely used in the grinding process that has higher requirement for the uniformity of the final products in wear-resisting material chemistry and metallurgy and glass industry and in recent years it is also used in the.
The characteristic of the rod mill is that in the grinding process the grinding medium is in line contact with the ore so it has a certain selective grinding effectProduct particle size is more uniform less crushing ore grainsWhen used in coarse grinding the processing capacity of the rod mill is larger than that of the ball mill.
The continuous grinding mills are designed for 24 hour per day continuous abrasive duty they offer a great deal of flexibility for pilot plants for instance the 16by 48sectionalized mill may be operated as: a a rod ball or pebble mill b in an open or closed circuit with cyclone or spiral classifier c a wet or dry grinding mill.
The granularity of the final products is even and the amount of the particles that are over crushed and ground is lowWhen used for coarse grinding the processing amount of rod mill is higher than that of the ball mill with the same specificationWhen the product granularity is required to be 2-0.
The journal of the south african institute of mining and metallurgy july 2001 165 introduction there are six parallel conventional milling circuits at palabora mining companyEach milling circuit consists of a rod mill followed by a ball mill in seriesCrusher product -9 mm is fed to the rod mill and the water is fed in ratio to the ore.
The noise of ball mill is also a difficult problemBall mill as one popular grinding equipment commonly used in chemical industry metallurgy mining and other industries in the process of production its minimum noise is 95 db a up to 120 db a which is one of the strongest noise in industrial production and it must be controlled.
The rod mill usually uses 50-100mm diameter steel rod as grinding medium while the ball mill uses steel ball as grinding mediumThe length of steel rod is 25-50mm shorter than the cylinder and it is usually made of high carbon steel with carbon content of 08 – 1; the loading capacity of rod is about 35 – 45 of the effective volume.
