The sieve is the main accessory to control the fineness of the crushed product, and it is also one of the main vulnerable parts of the crusher. The type and shape of the screen, the density of the holes, the wrap angle and the opening rate have an important influence on the crushing and screening effect. Sieve tablets are generally used in medicine, food, chemical and other fields.

Rice sieve is a kind of utensil used to sift the sand and crushed grains in grain, and it can also be used to contain food. The rice sieve is usually round. When in use, the pounded rice can be placed on the rice sieve. By shaking left and right, the fine rice bran and broken rice can leak out from the bottom of the sieve to obtain complete rice. The emergence of the rice sieve greatly simplifies the process of screening rice and improves the screening efficiency.
