Screening and grading of ore
Screening is the use of a wide range of particle size sieve to size the material is divided into several levels according to the job. Classification is based on the material in the medium (water or air) in the velocity of the different grain size into different jobs. Coarse material generally used for screening, that is greater than 0.25 mm material. Finer material, material that is less than 0.2 mm multi-purpose classification. But in recent years, domestic and international fine sieve is application of the grading of the grinding mineral products, the efficiency of such a classification higher than normal.
Classification of ore screening operation
According to the different purpose of screening, screening operations can be divided into five categories:
(1) independent screening. Limestone mining process plant
The aim is to be suitable for the user requirements of the final product. For example: In the metallurgical industry in the brown, often to a higher-rich iron ore screening into different grain size, qualified to enter the large blast furnace iron ore, fine ore is sintered by pellets or blocks into the furnace system.
(2) secondary screening.
This screening is mainly used in the concentrator crushing operations, the crushing operations play a supporting role. Generally have a pre-screening and screening of the other checks. Pre-screening is the ore into the crusher before the screening, with a sieve in the separation of ore from the crusher for the purposes of section already qualified. This can reduce the amount of ore into the crusher, the crusher can increase the yield.
(3) preparation and screening.
Its purpose to prepare for the next job. If re-processing plant in the jig before the screening should be graded material, the coarse, medium and fine grading of different products out.
(4) Select screening. used screening for sale
If the material is useful in various components of very different grain size distribution, classification can be obtained by screening the quality of different grain size, the low-quality grain screening, thus a corresponding increase in the quality of materials, and sometimes again this types of screening is called screening.
(5) dehydration screening.
The purpose of the screening material removal of water, is generally more common in the coal washery. In addition, the material moisture content of clay is high, also used for screening off the mud.
Three. Ore screening equipment ( Vibrating screening mesh )
Shaker (ore screening device) the most widely used in the concentrator, according to the different transmission can be divided into the following categories:
(1) eccentric shaker
(2) inertial shaker
(3) self-centering shaker
(4) resonance screen
