Research of Crushing Mechanism Based on Pulverized Coal Sample Preparation System

摘要

Coal is the main material for human's production and livelihood, and human pay more attention to it. Nowadays, Chinese crushing equipment's volume is bigger, in view of this phenomenon, the author put forward to design a pulverized coal intelligent sample preparation device. This design not only has small size, but also has coarse crushing, drying, screening, grinding, grading and pulverized coal's intelligent detection. It can well detect pulverized coal's composition and year. In this paper, the author research on this mechanism's coarse crushing device. Firstly, the author analyze the composition of coal to make a better foundation for crushing, then introduce the overall process of coarse crushing, and research the various parts of working principle and related parameters.
