Description

technical field [0001] The invention relates to a system for measuring the original particle size of sintered mixture. Background technique [0002] The raw material granules of sinter mixture are formed by mixing and pelletizing by controlling the delivery volume of various raw materials in proportion by the batching system; before measuring the original particle size of sinter mixture, it needs to be sieved. Traditionally, the raw material particles of the sinter mixture are directly sieved, manually sampled, manually sent, and finally the original particle size is measured. Since the original material particles of sinter mixture are wet and soft, direct screening will cause the surface of the original material particles to be damaged, stick and stick to the screen, destroy the original material particles, interfere with the test results, and the labor of traditional manual sampling High strength and low work efficiency; the stability, uniformity and reliability of sampli...
