The R-series three-dimensional vibrating screening and filtering machine uses a dedicated vertical vibrating motor, and is optimized with American technology. It utilizes the vibrators (i.e., unbalanced weights) installed at the upper and lower ends of the motor. The screen changing process is simple and convenient, which can be completed by two people within five minutes. It has a unique anti-clogging device, ensuring that the mesh holes will never be blocked. It has a good sealing effect, preventing powder from flying. It is small in size and light in weight, not occupying much space, and can achieve the classification of materials in four specifications.
