Problems solved by technology

The most important thing is that only a small amount of powder can be separated in one operation. Therefore, it is feasible for this method to be used for screening a small number of samples in the laboratory. If it is used in actual production, it is obviously unacceptable

Abstract

A rotary separator for screening spherical particles is composed of drive roller, driven roller, conveying belt, feeding hopper, drive motor for driving said drive roller via belt, height-regulating slide block mechanism for regulating the distance between drive roller and driven roller, tensional slide block mechanism for regulating the tension of conveying belt, spherical particles collecting bucket, aspherical particles collecting bucket, cleaning brush, and base.

Description

technical field [0001] The invention belongs to the technical field of powder screening, and in particular provides a rotating spherical powder screening and separating device. Background technique [0002] With the rapid development of modern science and technology, the application of powder materials is becoming more and more diversified, functional and refined. In some special application fields, many special requirements are put forward for the performance index of powder materials. The material is spherical particles within a certain particle size range, mainly because spherical particles have a high filling rate and have the largest filling amount under the same volume, and the spherical particles are in point contact with each other, and the filling state is stable. It helps to reduce the flow resistance of working fluid. The ideal form of cold storage materials is spherical particles of 154-280um. [0003] Although there are many ways to prepare spherical particle...
