Description

Technical Field

[0001] The utility model relates to the technical field of stone crushing, in particular to a stone crushing device which is convenient for screening. Background Art

[0002] Stone crushing is an important industrial process that aims to process raw stone into particles or powder that meet specific requirements. This process is usually achieved through physical or mechanical force, using professional equipment such as crushers and grinders. First, the raw stone needs to undergo preliminary processing, such as weathering, blasting, mining, etc., so that it can be taken out from the hillside or mine. Subsequently, the stone is sent to the crusher for primary crushing, where it is broken down into smaller pieces by crushing, impacting, etc. Then, the intermediate crusher further crushes the coarse-grained stone into smaller particles. During the crushing process, the vibrating screen plays a key role in separating stones of different particle sizes to ensure that the final product meets the specifications. In addition, the selection of crushing equipment and the setting of operating parameters have an important influence on the crushing effect, and need to be precisely adjusted according to the characteristics of the stone and processing requirements. The products after stone crushing are widely used in building materials, mining, chemical industry and other fields, providing important support for the development of related industries.

[0003] Stone crushing requires screening. The existing screening devices are large in size and complicated to operate. When faced with a small workload, the energy consumption is high, which is not conducive to environmental protection. At the same time, a large amount of dust will appear when the stone is crushed, which affects the environment and causes physical harm to the user, thereby reducing the working environment and the efficiency of the screening device.

[0004] Therefore, it is necessary to design and transform the screening device to effectively prevent the existing screening device from being large in size and complicated to operate. When faced with a smaller workload, the energy consumption is high, which is not conducive to environmental protection. At the same time, a large amount of dust will appear when the stone is crushed, which affects the environment and causes physical harm to the user, thereby reducing the working environment and reducing the efficiency of the screening device.
