1. Jigger processing raw materials with large difference in specific gravity of minerals can use thinner bed to accelerate stratification. And in the processing of raw materials with smaller specific gravity difference, or in the case of the requirement of high quality concentrate, the bed can be thicker. Generally speaking, the thick bed work is not chaotic, easy to manoeuvre, but because the time used for loosening is longer, the processing capacity of the equipment is reduced.

2. The total thickness of the jigger bed is customarily calculated by the height from the screen surface to the tail weir. Changing the height of the weir plate, the bed thickness is also changed. 3.

3. When the diaphragm jigger treats coarse-grained raw materials, the bed thickness should be not less than 5-10 times the diameter of the particles in the feed ore, generally between 120-300mm.

4. When the diaphragm jigger treats fine-grained raw materials, the artificial bed (also known as the bottom sand) is used for through-screen discharge.

The choice of artificial bed stone:

1. the particle size of artificial bedrock should be more than 3-6 times of the particle size of the incoming ore and 1.5-2 times larger than the size of the sieve hole, and it is appropriate that the specific gravity is close to or slightly smaller than the specific gravity of the heavy minerals.

2. When dealing with easy-to-select ores, the artificial bed layer can be thinner; when dealing with low-grade ores, it should be thicker. I have tungsten ore tin ore re-election plant of artificial bed thickness is generally 10-50mm, and in the treatment of iron ore for the feed size of 4-6 times.

The thickness of the ore layer located in the upper part of the artificial bed layer is generally more than 20 times the feed size. Even so, its thickness is still much thinner than the bed in a coarse-grained jigger.
