Solid mineral sample preparation system

Abstract

The invention relates to the field of solid mineral sample preparation, and particularly discloses a solid mineral sample preparation system. The system comprises a lifting platform, an loading device, a feeder, a crusher, a fixed mass division machine and a collection device, wherein a cavity is formed in a material bin of the feeder, a first feeding opening is formed in the top of the material bin, a first discharging opening is formed in the bottom of the material bin, and the cavity is communicated with the first feeding opening and the first discharging opening; the feeder further comprises a rotating shaft which is installed on the material bin, is rotatably connected with the material bin and penetrates the first discharging opening; the feeder further comprises a driving device which is connected with the rotating shaft; the feeder further comprises a feeding knife, one end of the feeding knife is fixed onto the rotating shaft, the other end of the feeding knife is attached tothe inner wall of the material bin, the feeding knife is located on the bottom of the cavity, and the feeding knife rotates to scrape a material in contact with the feeding knife from the material binside walls to the discharging opening, so that the material, away from the discharging opening, on the bottom of the material bin does not pile up, and discharging is even; the feeding knife rotatescontinuously, and the material in the material bin decreases layer by layer, so that discharging is continuous and stable, and the representativeness of a prepared sample can be ensured.

Description

technical field [0001] The invention relates to the field of solid mineral sample preparation, in particular to a solid mineral sample preparation system. Background technique [0002] The quality of ore-like bulk materials needs to be tested in the process of production, trade and use. Taking coal as an example, when the quality of coal is tested, it is necessary to first prepare the collected coal samples with large particle sizes into small and representative samples with small particle sizes, and test the samples to verify their quality. [0003] According to the provisions of GB / T 475-2008 "Methods of Manually Collecting Commercial Coal Samples", the commercial coal samples need to be collected manually first, and then the same batch of samples needs to be crushed and divided at one time to obtain samples. Coal is a bulk material. The commercial coal samples collected manually are not only large in quantity but also large in particle size. A sampling unit is 300-500kg ...
