Background

In bulk material processing systems, material fine particle crushing is often the last processing procedure of a material process, and therefore, the crushed particle size of the material is of great importance to the process system. In the process of crushing fine material particles, the fine crusher is abraded to a certain extent, so that the crushed material is irregularly larger. If not adjusted in time, a need arises to affect subsequent processes. For example, in a circulating fluidized bed furnace, if the particle size of the material entering the furnace is larger, coking of the boiler, incomplete burning of raw coal, excessive air entering the furnace bed and the like can be caused. Conventionally, a problem was found in the boiler, and a sampling process was performed. Usually, when a crushed sample is taken, the whole conveying system is manually stopped, and the sample is taken on a lower-level belt of a fine crusher, so that the problems of no separation of the sample materials of a crushing sieve, complicated system stop and the like exist.

Therefore, a new online sampling device for a fine crusher is needed to solve the above technical problems.
