In order to make the jig chamber water flow distribution evenly, in the side wall above the diaphragm is set up a inclined baffle, the degree and length of baffle should be appropriate, so that the flow line length of the pulsating water from the diaphragm to the screen surface is roughly equal. The water tank of the moving cone diaphragm jig is a cut cone, because the diaphragm is located below the water tank, the water flow is basically vertical through the screen plate and the distribution is more uniform, but the water tank because the diaphragm and the transmission mechanism are below the water tank, the maintenance and management is not convenient, and the moving cone should bear the gravity of the concentrate under the screen, when the amount of concentrate under the screen is more, the diaphragm is easy to damage, and the ore discharge is not convenient. Round bottom tank, this tank shape facilitates water flow and reduces water flow resistance. The distribution of water velocity in the jig chamber is more uniform than other ones, but it is difficult to discharge the concentrate under the sieve. If the circular tank gradually becomes tapered downward, the discharge of concentrate under the screen can be improved.
The width and length of the jig chamber The area of the jig chamber above the jig box affects the processing capacity and sorting effect of the equipment. The area increases and the processing capacity increases. Under the condition of the same capacity, increasing the area of the jig chamber can increase the residence time of the material in the jig chamber, which is conducive to the recovery of minerals. The determination of the width of the jig chamber, in addition to the main consideration of production capacity, should also make the feed can be evenly distributed along the width and the pulsating water flow evenly distributed along the width. Width is too narrow, processing capacity is too small; The width is too wide, the feed is not easy to distribute evenly, and the distribution of pulsating water is not easy to distribute evenly, away from the diaphragm, the pulsating water speed is small, the bed is less loose, and the opposite is near the diaphragm. Therefore, the width of the jig chamber is about wide, and the difference in bed looseness along the width is about significant. Usually the width of the jig does not exceed 1m, and in some cases up to 1.6m. The circular jig of large size has a long circumference, so the rotary rake is set at the central feeding place to make the feed from the central can be evenly distributed along the radial direction. The length of jig chamber mainly affects the sorting effect, so the length should be determined according to the time required to meet the stratification of materials. In this time, the heavy ore particles in the upper layer should be able to move to the screen surface, and the gangue particles in the lower layer should be able to move to the upper layer and discharge. The time the material stays in the jig chamber is related to the particle size, density, feed concentration, treatment capacity, water under the screen, bed thickness, stroke, stroke rate and other factors. For feed with coarse grain size and large density difference, the length of jig chamber can be shorter; When the feeding amount is large, the concentration is small or the water under the screen is large, the length of the jig chamber should be longer.
