Stone waste processing equipment

Abstract

The invention discloses stone waste processing equipment. The stone waste processing equipment comprises a feed conveying frame, a material crushing mechanism connected with a discharge port of the feed conveying frame, a guide mechanism connected with a discharge port of the material crushing mechanism and a material smashing mechanism arranged at a discharge port of the guide mechanism. The stone waste processing equipment directly crushes broken stones and feeds the crushed stones into the smashing mechanism to be smashed. Moreover, a high-temperature medium for drying carries out heat conduction through a stainless steel inner sleeve to dry stone powder without direct contact with the stone powder, and discharged waste gas does not need to be subjected to dust removal treatment in thecrushing process. Besides, an outer sleeve gradually decreases from a feed section to a discharge section, water vapor generated in the crushing process of the stone powder is squeezed from the discharge section to the feed section and finally passes through a guide pipe, the stone powder adhering to water vapor is blocked by the broken stones and adheres to the surfaces of the broken stones to gointo the crushing mechanism for crushing along with the broken stones again, the environment is effectively protected, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to stone waste processing equipment. Background technique [0002] At present, the stone waste in the prior art is usually processed into stone powder for secondary use. In the process of processing stone powder, the crushed stone is first crushed into small particles, and then dried, and the dried small particles enter the pulverizer. For crushing, because the crushed stone is in a wet state during the crushing process, it will not produce a lot of dust, but in the drying process, a certain amount of dust will be generated, especially in the final crushing process, which requires a lot of dust removal equipment In addition, if the wet crushed stone is first crushed and then dried, it will be charged with static electricity during the crushing process, and the powder will stick together and form a block, and then dust explosion will easily occur during drying Phenomenon.
