Abstract

The invention discloses a rotary separating horizontal type sand mill without a screen cloth and relates to the field of sand mills. The rotary separating horizontal type sand mill without the screencloth comprises a sand mill body, a barrel body arranged on the sand mill body, a main transmission used for driving the sand mill to run and a dispersor arranged in the barrel body; a material feeding port is arranged at one end of the barrel body and a separator is arranged at the other end; the dispersor comprises a dispersing shaft, of which one end is connected with the main transmission, anda plurality of dispersing devices distributed on the dispersing shaft; the separator is arranged perpendicularly to the barrel body and comprises rotational flow cavities; the bottoms of the rotational flow cavities are connected with return pipes, the tops of the rotational flow cavities are connected with outflow pipes and the side walls of the rotational flow cavities are connected with separator inflow pipes; the facing direction of outlets of the return pipes and the facing directions of inlets of the separator inflow pipes are correspondingly the same with and reverse to the rotary directions of the dispersing devices in the barrel body. By means of the sand mill, the conventional screen cloth separating mode can be replaced, the structure is simple, the service life is long, the manufacture cost is low and the technical effect of effective grading and separating of grinding mediums and materials can be realized.

Description

technical field [0001] The invention relates to the field of sand mills, in particular to a screenless rotary separation horizontal sand mill. Background technique [0002] Sand mill is a widely used wet ultra-fine grinding equipment, which can be roughly divided into horizontal sand mill, basket sand mill, vertical sand mill and so on. With the continuous improvement of product fineness requirements, the size of the grinding media used is getting smaller and smaller, and the separation of small-sized grinding media is one of the most difficult problems in the research and development of sand mills. In the past, the method of reducing the separator gap was generally used, but this often led to the clogging of the separator. [0003] In recent years, the dynamic separation screen has been arranged in the center of the rotor to reduce the clogging and wear of the separator by reducing the distribution of grinding media and large particle materials in the central area. Howeve...
