Key technologies include crushing and screening, used to break raw coal into particles suitable for processing; heavy media separation and flotation, used to separate impurities such as rock and ash from coal; and dry separation, used to further improve coal purity. These processing technologies not only effectively increase coal's calorific value and combustion efficiency, but also reduce environmental pollution and ensure the efficient utilization of coal resources.

[0003] A Chinese patent publication (publication number: CN 213762817 U) discloses a vibrating screening machine for coal washing plants, comprising a base, a feeding mechanism, and a vibrating mechanism. The vibrating mechanism is fixedly mounted above the base, and the feeding mechanism is fixedly mounted above the vibrating mechanism.
