In the working process of the system, after the auger sampling machine collects the representative coal sample of full section, the rotary hydraulic crane lifts the sampling head and puts the coal sample into the receiving hopper. The coal sample is uniformly and continuously sent to the crusher by the feeder, and the crushed coal sample is then divided into smaller parts, so as to obtain the required product samples. Finally, the samples are collected into the dustproof and moisture-proof sample tank.
1. Scope of application
The system can directly take samples from coal piles, train skins, car carriages and cabins. The installation methods can be divided into fixed type, track mobile and vehicle mobile.
