Tumbler screen is an low frequency and high efficiency rotary vibrating screen which simulate manual hand shaking motion. The working principle of tumbler screen is instantaneous movement of the radial direction displacement and circular motion with this radial displacement as the axis (spiral motion), the exciter generates of swing tumbler screen nonlinear three dimensional motion, the materials also generates similar motion of manual operation, and achieve separating purpose. Application: round shape material, Cylindrical, flake shape material or other irregular shape which are difficult to sieve and easy to block the screening mesh. Large sieving capacity and high efficiency, High screening accuracy. It is suitable for fine and super fine particulate materials. Sieving accuracy reach to 99%銆?/p> Certificate We have international qualified certificates for Tumbler Screen.Fine Screening Equipment price website:http://www.yrscreen.com/fine-screening-equipment/
