Description

Geological mineral exploration ore sample breaker Technical Field The utility model relates to the technical field of geological mineral exploration, in particular to a geological mineral exploration ore sample crushing device. Background Geological mining field investigation is basic work of mineral resource development, and aims to find out geological conditions of a mining area, mineral resource reserves and mining technical conditions through a scientific method and provide reliable basis for mine construction design, production and resource management. In the process of exploration, geological measurement, geophysical exploration, geochemical exploration, drilling and pit test are needed, and ore sample crushing is a core link of geological mineral exploration, and directly influences sample representativeness, analysis precision and reliability of resource evaluation. The existing ore sample crushers are divided into a jaw crusher, a cone crusher, a twin-roll crusher, a hammer crusher, a finely-divided disc grinder, a vibration mill and the like. The common defects of the equipment are that iron equipment easily causes high iron content in an ore sample and causes inaccurate subsequent measurement, and secondly, uneven granularity, and serious subsequent analysis errors caused by over-crushing or under-crushing. In view of the foregoing, it is desirable to design a device for crushing geological mineral exploration ore samples to solve the above-mentioned problems. Disclosure of utility model The utility model aims to solve the technical problems that the existing ore sample crusher easily causes high iron content in an ore sample and serious subsequent analysis errors caused by uneven crushing particle size, and provides a novel geological mineral exploration ore sample crushing device. In order to solve the technical problems, the utility model provides a geological mineral exploration ore sample crushing device which comprises a crushing machine body, wherein a feed hopper is arranged at the top of the crushing machine body, a screening device is arranged at the upper part in the crushing machine body and communicated with the feed hopper, a plurality of ceramic grinders which are communicated are arranged at the bottom of the screening device, a grading screening frame is arranged at the middle part in the crushing machine body and positioned below an outlet guide cylinder of the grinder, a vibrating motor is fixedly arranged at the bottom in the crushing machine body, and the output end of the vibrating motor is connected with the grading screening frame.
