Description

Technical Field

[0001] The utility model belongs to the technical field of quarries, and in particular relates to a crushed stone screening device for quarries. Background Art

[0002] Mining of mineral deposits can be done underground or in the open air. Work performed underground without natural lighting is called underground work, and the quarry is also called an underground quarry. Quarries that mine under natural light are called open-air quarries. The sources of ecological damage in quarries can be divided into two categories: human damage and natural damage. Whether it is human damage or natural damage, it will eventually lead to a series of serious ecological and environmental problems such as vegetation destruction, land exposure, soil erosion, ecological environment deterioration, and damage to the natural landscape. During the stone mining process, quarries need to screen the mined stones to separate the crushed stone from the stones. However, the current screening of crushed stone generally uses a filter screen, which lacks the function of multiple screening. Crushed stone is easily retained between the stones during the screening process, resulting in incomplete screening of crushed stone, affecting the crushed stone screening effect. Therefore, a quarry crushed stone screening device is needed. Utility Model Content
