The factors that affect the jigging selection are:
1)
Stroke and stroke. This is an important factor in the jigging process. Strokes and strokes determine the speed, acceleration and looseness of the water in the jig. The stroke and stroke are related to the particle size, density, and thickness of the bed. The coarse-grained material should be selected with a large stroke and a small stroke. The fine-grained material should be washed with a small stroke. 2)
Water consumption. There are two aspects to the water consumption of the jig, that is, the water supplied from the sieve to the mine end and the water under the sieve. The larger the amount of water on the sieve, the faster the discharge rate of light products, and the larger the treatment volume, but the stratification is incomplete, and the light products are easily mixed into the mineral particles with higher density. The main function of the additional water under the sieve is to enhance the upper flushing flow and make the bed loose for sorting. 3)
Bed thickness. The thicker the bed, the longer the time required for the loose bed and the longer the delamination time. When the density difference between the large-density particles and the small-density particles is large, the bed layer may be thinner; when the density difference is small, the bed layer may be thicker. The thickness of the bed is increased, the quality of the heavy product is improved, and the quality of the light product is lowered. When the bed is thin, the quality of the heavy product is lowered and the quality of the light product is improved. At the same time, the factors affecting the jigging selection process are the area of ​​the jig screen surface, the size and shape of the sieve hole, the size and uniformity of the feed amount. 
Silicone Mold
Silicone mold is made of food grade silicone,it won't harmful our body.People can use it safely.It is resistant to high temperature and low temperatur.It have many usage such as can uesd for Silicone Cake Molds,chocolate molds,it can be called as Silicone baking molds,silicone,silicone sweet moulds.And also have another two,silicon mold soap,Silicone Ice Molds.
And it won't break easily,so don't worry about its quality,we will provide best quality for customers.
