Pulverizer with screening secondary treatment function

Abstract

The invention discloses a pulverizer with a screening secondary treatment function. The pulverizer with the screening secondary treatment function comprises a flow dividing box, a secondary pulverizing barrel and a material collecting barrel, a primary pulverizing barrel is arranged at the top of the flow dividing box, the interior of the primary pulverizing barrel is rotatably connected with a grinding roller, and the top of the secondary pulverizing barrel is fixedly connected with a second motor. The output end of the second motor penetrates through the secondary pulverizing barrel to be fixedly connected with a crushing cutter, the bottom of the outer wall of the secondary pulverizing barrel is fixedly connected with a second fan, the output end of the second fan extends to the bottom of the secondary pulverizing barrel, so that raw material blocks are crushed into powder, unqualified raw materials are pulverized through the crushing cutter, direct cutting and pulverizing through the crushing cutter are avoided, and the service life of the crushing cutter is prolonged; and the materials which are ground into powder are blown by the fan when entering the flow dividing box, so that fine powder falls down towards one side of a fine selection barrel, flow dividing of qualified materials and discharged materials is achieved, secondary crushing of the qualified powder is avoided, the crushing time of a crushing cutter is shortened, and the production efficiency is improved.

Description

Technical field: [0001] The invention belongs to the technical field of milling equipment, in particular to a mill with the function of screening and secondary treatment. Background technique: [0002] During the production process, due to material needs, some raw materials need to be crushed and ground, and the raw materials are cut and ground by the fast-rotating blade. [0003] In the prior art, most of the traditional milling devices cut directly through the high-speed rotating blades. Some surfaces are relatively hard, such as dry corn. Time to grind, improving processing time. Invention content: [0004] The object of the present invention is to provide a kind of pulverizer with screening secondary processing function in order to solve the above-mentioned problems, through the grinding bar No. Squeeze each other to break the raw material into powder, avoid cutting and grinding directly through the crushing knife, and improve the service life of the crushing knife; ...
