Adjustable precise crushing and grinding module

Abstract

The invention provides an adjustable precise crushing and grinding module. The grinding module comprises: a drive source; a lifting mechanism; a grinding and crushing hammer connected with the drive source and comprising an upper end body, a lower end body and a pushing body integrally molded from top to bottom, wherein the upper end body and the lower end body are both circular tables, the pushing body is a cylindrical body, the outer diameter of the upper end body is increased from top to bottom in sequence, multiple cutter bodies are arranged on the outer wall, and the outer diameter of thelower end body is reduced in sequence from top to bottom; and a crushing and grinding cylinder comprising a first circular table cavity, a second circular table cavity and a second cylinder cavity coaxially arranged in sequence from top to bottom, wherein the crushing and grinding hammer is positioned in the crushing and grinding cylinder, and the crushing and grinding hammer is coaxial with thecrushing and grinding cylinder. The grinding module enables materials to realize the process flows of cutting, crushing, coarse grinding and finish grinding on one equipment, and adjusts the crushingprecision of crushed objects online under the condition of not replacing the crushing and grinding hammer.

Description

technical field [0001] The invention relates to the field of material crushing and grinding, in particular to an adjustable precise crushing and grinding assembly. Background technique [0002] In the pretreatment stage of physical and chemical analysis samples such as biopharmaceuticals, bioengineering, soil testing, and solid material composition testing, crushing and grinding devices are usually used to crush materials and grind them to a certain accuracy requirement. At present, the commonly used equipment on the market mainly includes blade type, ultracentrifugal type, planetary and vibrating ball mill type, jaw type, disc type, vibrating cup type, cutting type, mortar type, etc. However, most of these equipments cannot realize coarse grinding and fine grinding at the same time. Usually, the solid material is crushed and then put into another equipment for fine grinding. In addition, the fine grinding equipment can only grind samples with one particle size precision eac...

Problems solved by technology

However, most of these equipments cannot realize coarse grinding and fine grinding at the same time. Usually, the solid material is crushed and then put into another equipment for fine grinding. In addition, the fine grinding equipment can only grind samples with one particle size precision each time. , when the particle size accuracy of the sample changes, it is usually necessary to replace the grinding head
