An adjustable modular crushing and grinding equipment

Abstract

The invention provides an adjustable modular crushing and grinding equipment, which includes a grinding assembly and a filter assembly. The grinding assembly includes a driving source, a lifting mechanism, a crushing and grinding hammer, several cutting knife bodies and a crushing and grinding cylinder. The crushing and grinding hammer includes an upper end body, The lower end body, the pusher body and a number of cutting knife bodies, the crushing and grinding cylinder includes the first conical chamber, the second conical chamber and the second cylindrical chamber coaxially arranged in sequence from top to bottom, the first conical chamber and the The inner diameter of the second round platform chamber decreases sequentially from top to bottom, and the filter assembly includes a cylinder body, a vibrating body, a first power source, a turning bar, a screen fixing sleeve, a screen and a second power source. The present invention can realize Coarse grinding and fine grinding, and can adjust the fine grinding particle size of the material without changing the grinding hammer. At the same time, the screen can be automatically turned over to automatically dump out the materials remaining on the screen after screening.

Description

technical field [0001] The invention relates to the field of material crushing and grinding, in particular to an adjustable modular crushing and grinding equipment. 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 ea...

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, the grinding head usually needs to be replaced. In addition, the filtering part of these devices is usually installed with a fixed screen, which can only filter materials of one particle size at a time. Equipment, the sieving method of the sieve is to shake back and forth. This method has low screening efficiency and poor effect, and there are materials remaining on the sieve after screening.
