Jan 01, 2017 · The run-of-mine ore is reduced to a particle size of less than 1 mm in the comminution circuit and concentrated using gravity separation. The comminution circuit comprises two-stage crushing and single-stage grinding in a ball mill in closed-circuit with a highfrequency screen. A detailed circuit audit was undertaken at the plant to understand

Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in ...

Grinding process is a subsequent step after the ore crushing process, and be an important part of the preparation work before mineral sorting. The ore grinding machine is usually working with the classifier.
The grinding mills grind the feed material to a smaller size, and the classifier divides the ground products into qualified and unqualified products. In which, the unqualified material is returned to grinder mill for re-grinding. The classification process includes pre-classification, checking classification, and controlling classification. Related products: crushing and grinding machine, rod mill, ball mill, feeder & conveyor belt, particle classifier
The main factors affecting the determination of the number of grinding sections are: ore grindability, mineral characteristics, feed size, required grinding size, production scale, etc. The result shows that, for ore beneficiation processing, one or two stages of grinding can achieve the target particle size required for beneficiation, multi-stages usually determined by the high precision requirement and multi-phase separation
Compared with the two-stage grinding process, the main advantages of a stage grinding process are less equipment, low investment, simple operation, short downtime. However, the one-stage grinding mill has a wider range of grain size, which is difficult to obtain a fine final product
When to adopt one-stage grinding? The maximum particle size of final product is 0.2 ~ 0.15mm ( -200 mesh 60% to 79%); Small processing plant, to simplify the equipment configuration and to save cost, its required fineness is -200mesh 80%. Layout and configuration Generally, grinding machine working with the classifier, three common one stage grinding process circuit as following. One stage grading process with checking grading operation is the most widely used. The ore is directly fed into the grinding machine, and the optimum particle size for the ore is generally 6-20 mm. Particle checking classifier separates the ground material into qualified products and unqualified products, the unqualified materials are sent back to grinding mill
When the ore contains a large amount of fine qualified ore, and it is necessary to pre-separate the soluble salts contained in the raw ore, the one-stage grinding process with pre-grading and checking classification should be employed
