Parameter Description: sieve plate-type hydraulic classifier also known as Code Groove watts (Denver)-type hydraulic grader, is the use of sieve-plate subsidence caused by interference in terms of equipment. The body shape for the corner of the cone-shaped boxes, boxes with vertical partitions into 4 ~ 8 graded rooms. Each room off an area of 200mm × 200mm. Away from the room at the end of a certain height to set sieve.
Sieve drill 36 ~ 72 diameter 3 ~ 5mm of the sieve. Pressure water from the bottom to the entry sieve by sieve upward mobility. In the sieve plate at the top of the mineral particles suspended group intervention stratified settlement. Through the center hole coarse sieve to drain emissions control with the cone-shaped plug. Pulp from one side to the entry, followed by entry into the various rooms, each room a gradual increase in water velocity decreases, thus obtained at all levels, from coarse to fine a product. Grade indoor water velocity distribution is uniform up to the classification results have significant impacts. Reduce the number of mesh and the corresponding increase in the sieve can be to some extent improve the results. However, the uneven distribution of water velocity is inevitable. Stir the resulting secondary reflux an important reason why the efficiency is not high. Sieve-plate-type hydraulic classifier has the advantage of simple structure, no momentum. With mechanical agitation hydraulic classifier comparison, a high degree of small, easy to configure. Select plants according to the different processing capabilities, made of four rooms, six rooms, 8 rooms of different specifications. This grading machine in our small and medium sized tungsten ore dressing plant used more often.
