Material crushing and grinding device with improved material crushing cutters and improved discharge port

Abstract

The invention provides a material crushing and grinding device with improved material crushing cutters and an improved discharge port. The material crushing and grinding device comprises a machine shell, a material crushing drum and grinding rollers. The material crushing drum is arranged at the upper end of the interior of the machine shell. The grinding rollers are arranged at the lower end of the interior of the machine shell. The axial direction of the material crushing drum is perpendicular to the axial direction of the grinding rollers. The material crushing drum comprises two half drum bodies with side walls hinged. Each same half drum body is controlled to be opened or closed through a switch assembly. The multiple protruding material crushing cutters are arranged on the inner wall of the material crushing drum. The material crushing cutters are distributed on the inner wall of the material crushing drum in a spiral and staggered manner. The discharge port is formed in the lower end of the machine shell. A material crushing and screening tank is arranged under the discharge port. The material crushing drum comprises the two half drum bodies with the side walls hinged. The material crushing cutters are arranged on the inner wall of the material crushing drum. In this way, materials can rotate in the material crushing drum and be repeatedly crushed, and the crushing effect of hard materials is more thorough. Meanwhile, the materials are crushed in the closed material crushing drum, it is effectively avoided that the hard materials fly out from a feed port, and safety accidents are avoided.

Description

technical field [0001] The invention relates to the field of grinding equipment, in particular to a crushing grinding device with an improved crushing knife and a discharge port. Background technique [0002] In the production process of bricks or cement, some materials with large particles need to be crushed before use. Otherwise, materials with too large particles will easily cause problems such as uneven density of bricks. Although common pulverizers can also crush hard materials into smaller Small particles, but because the crushing knife is set on the outer wall of the crushing drum, it cannot be crushed repeatedly, and the overall crushing effect is not good. At the same time, when the high-speed external crushing knife collides with hard materials, Hard materials often fly out from the feed port, which is likely to cause unpredictable safety accidents. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings and deficie...
