Problems solved by technology

Germany and others have developed vertical roller mills for micro-grinding processing. The vertical roller mill uses a material bed to crush materials, and the grinding rollers directly pressurize the materials, so that the materials are crushed by extrusion and shearing, and the energy utilization rate is high. High, but the structure is complicated and the cost is relatively high

Embodiment Construction

[0027] specific implementation plan

[0028] Embodiments of the present invention will be described below according to the accompanying drawings.

[0029] As shown in Figure 1, z 1 = The involute conjugate tooth surface 3 of 17 teeth is evenly distributed on the outer cylindrical surface of the grinding roller 1 and is connected with 1 to form a gear grinding roller, z 2 =z 1 = The involute conjugate tooth surface 4 of 17 teeth is evenly distributed on the outer cylindrical surface of the grinding roller 2 and is fixedly connected with the 2 to form another gear grinding roller. The axes of the two gear grinding rollers are parallel, and the center distance a is placed In body 5, each gear grinding roller is at constant speed ratio n 1 =-n 2 Rotate relative to the grinding body 5 around their respective axes, and the grinding body 5 is respectively provided with a feed inlet 6 and a discharge outlet 7 to form a micro-grinding gear mill; the two gear grinding rollers are st...

Abstract

The invention discloses a micro-grinding gear grinder, belonging to micro-grinding machinery. The technical scheme includes that a grinding roller (1) and a conjugate tooth profile (3) uniformly distributed on the surface of an outer cylinder of the roller compose a gear grinding roller, and a grinding roller (2) and a conjugate tooth profile (4) uniformly distributed on the surface of the outer cylinder of the roller compose one another gear grinding roller. Two gear grinding rollers with parallel axes and definite central distances are placed in a grinding body (5), each gear grinding roller is in toothed rotation around each axial cord relative to the grinding body (5) via fixed velocity ratio, and a feed inlet (6) and a feed outlet (7) are respectively arranged on the grinding body (5), forming the micro-grinding gear grinder. The working principle of the invention is that the material is disintegrated through the squeezing, grinding and shearing of the two tooth surfaces of the rollers, the invention can be adaptable to micro-grinding of powder or liquid material of the fields of chemical industry, building material, drug industry and the like.

Description

technical field [0001] The present invention is a micro-grinding gear mill, which belongs to the micro-grinding grinding machine (as shown in Figure 1); this micro-grinding gear mill is formed by meshing and rotating between two center-distance gear grinding rollers, and the tooth faces of the two grinding rollers squeeze the material. Pressing and grinding to achieve crushing of materials; it can be used in chemical industry, building materials, light industry, medicine, agriculture and other fields to finely pulverize powder or liquid materials. technical background [0002] Micro-grinding technology is a crushing technology developed to meet the particle size requirements of modern chemical, electronic, biological and other new materials and new processes. The method of micro-grinding is mainly mechanical crushing, including high-speed mechanical impact mill, airflow Grinding equipment such as grinding mill, stirring mill, ball mill, roller press mill, etc., as well as pr...
