Overflow ball mill handbook---installation and maintenance

Ball mills are the main machines in the grinding process. Mineral processing experts will choose different ball mills according to the different properties of ores, such as particle size, capacity. Ball mills are divided into wet ball mill and dry ball mill, overflow ball mill and grid ball mill. In this passage, Xinhai will mainly introduce overflow ball mill.

Installation of ball mill and rod mill

Xinhai experts tell you how to use linear vibrating screen!

Linear vibrating screen is a kind of important screening equipment in mineral dressing. It is used behind the grinding processing. The products on the linear vibrating screen will return to grinders, and the products under the screen will go to the next process. There are some tips to use linear vibrating screen:

Some tips of auto centering vibrating screen

Auto centering vibrating screen is developed by Xinhai used in screening link behind grinding. It is more efficient than other normal vibrating screen. There are some tips to maintain auto centering vibrating screen:

How to maintain round vibrating screen in mineral processing

Round vibrating screen is widely employed in mineral processing for screening different size ore. It plays an important role in the whole processing line. So correct operation and maintenance of round vibration screen guarantees the smooth operation of the whole process line.

Guide Book of all kinds of crushers

The crushers below are widely used in mineral processing industry. The more users know them, the higher efficiency they bring.

The Importance of Even Feeding to Ball Mill in Operation

Ball mill should keep even feeding in operation;  the even feeding means stable feeding quantity and same particle size  distribution.

All slime cyanidation-countercurrent method is successfully applied to a gold mine

The original beneficiation process of the gold mine was all slime cyanidation CIP process. Because  of the change of mining method, the mud content reached more than 15%, which  makes the leaching period longer and limited processing capacity; the flotation  recovery rate decreased; the production cost became higher. Xinhai needed to change  the process to reduce the cost. After contracting this gold reconstruction  project, Xinhai decided to take the test with all slime  cyanidation-countercurrent washing-carbon solution method, because the required leaching ore particle of this new process is larger than the process of  original process.The problems of all slime cyanidation CIP process This process required the leaching ore  granularity is fine, -200 mesh accounted for 85%, but the gold mine granularity  is coarse, and the mill processing capacity is limited resulting in the entire  gold processing decreasing, and the cost of ore dressing increasing; secondly, carbon leaching carbon was weared seriously reaching 120g/t according to Xinhai  Research Institute testing; so the overall economic benefits were low. The all slime cyanidation-countercurrent  washing-carbon solution method designed by Xinhai Mineral Processing Research  Institute adopted classifying control and thickening before leaching. The  details of the test as follow

The introduction of common mineral processing methods

A variety of ores may need different mineral processing methods. Customers have little knowledge about that. As a result, Xinhai Mining Machinery Co., Ltd. will introduce some detailed beneficiation methods for all customers. In terms of different ores, mineral processing methods are different. Thus, we need know the characteristics of ores, and then the method can be assured.

Introduction of common crushing equipment

Along with the development of science and technology, a variety of new high-efficiency crushing equipment mushrooms and has been widely used. However, a jaw crusher, a cone crusher and a gyratory crusher are mainly used for processing metallic ores.
