The tumbler screening machine imitates the manual screening action and process of humans, doing three-dimensional circular motions, cleverly combining screening and jogging. There is both circular motion and upward throwing arc motion. The tumbler screening machine has the characteristics of high screening accuracy, high efficiency, large output (up to 5-10 times that of ordinary vibrating screens), and long screen life. It can easily complete the screening process with large output and high density. It is suitable for all fine and ultra-fine powder and granular materials, especially for materials that are difficult to handle.
After comparison, it is found that for 30 mesh coarse materials, the output of the vibrating screen and the tumbler screening machine are basically the same. For materials as small as 500 mesh, the output of the tumbler screening machine is much higher than that of the ordinary vibrating screen, and the tumbler screening machine is 5-10 times that of the vibrating screen. Especially for hard materials that produce severe abrasion on the screen, the service life of the screen of the tumbler screening machine can be doubled.
The vibrating screen is to screen materials through the principle of high-speed vibration. Because of high-speed vibration, it will destroy the shape of the material. Many granular, crystallized and brittle materials are not suitable for vibrating screen screening, such as chicken essence, monosodium glutamate, sugar, cooked food and so on. The tumbler screening machine is a slight elliptical swing movement. There is no high-speed vibration, which has little effect on the material, does not damage the shape of the material, and greatly improves the yield of the material.
