Problems solved by technology
Although this vertical rotary mortar mill has the advantages of finer grain size and uniform discharge at one time, when this equipment is working, when the material is crushed in the upward process, there are also the following two defects: one is The upward movement of materials needs to consume a certain amount of energy, and the energy consumption is relatively high. Second, when grinding wet or sticky materials, it is often impossible to discharge them normally. service life

Provided is a rotary cone mill, comprising a base, an upper body, a middle body, a lower body, a driving wheel, a main shaft, a bearing support, a rotary cone, a grinding roller, a pressure device and a clearance adjustment device. A grinding surface matching with the grinding roller is arranged on the outside of the rotary cone, wherein the grinding surface is a conic section with a small upper part and a big lower part, and an angle formed by the main bus bar and the horizontal plane is 5 DEG to 45 DEG. The mill of the invention has the advantages of low energy consumption, unblocked discharge, simple structure, easy maintenance, wide range of application and long service life. The mill can even normally discharge materials which are even comparatively wet or have sticky nature.
Description
technical field [0001] The invention relates to a crushing device, in particular to a cone mill in which materials are crushed by grinding rollers during the process of material sliding down the cone. Background technique [0002] Existing roller mills such as Raymond mills cannot be used in occasions where the finished product particles are relatively coarse. In order to overcome the defect of roller mills such as Raymond mills, Wang Guifu successively applied for two patents that can be used as dry or wet fine grinding or pre-grinding: the rotary mortar roller mill disclosed in CN2799073Y and the rotary mortar disclosed in CN201020388Y pulverizer. The technical solutions adopted by these two mills are to make the materials entering the middle of the mortar plate from the feed inlet go up along the mortar plate under the action of the centrifugal force generated by the rotation of the mortar plate. The grinder is ground between the grinding roller and the working chamber ...
