Tumbler screening technique
Tumbler screening is a separation method that uses three-dimensional elliptical movement to separate very fine particles from larger ones. Tumbler screening is a mechanical screening technique used in many fields that deal with raw materials and building materials for process and reuse. This technique can achieve 99% high efficiency with its circular movement. Machines with tumbler screening techniques are commonly used because of its unique rush design, high life time utility, and the flexible angular velocity the machines can achieve. However, this type of machine requires low feed flow rate, and the particle size for separation has to be controlled within a specific range. Furthermore, the performance of the process also depends on the intensity of the vibration. The water steam treatment is also an issue of this screening technique since this technique is applied worldwide. Presently, the most effective and environment-friendly way for processing of the waste treatment is to classify the products. The products are usually split into four categories, including organic, inorganic, hazardous and recyclable. Nowadays, scientific research continues for further development of the method. Overview The tumbler screening technique is a separation method that applies an elliptical movement in three dimensions, which helps to efficiently produce
