AI Technical Summary

Technical Problem

The existing crushing and screening processes in sand and gravel aggregate production and processing are inefficient, resulting in dust pollution that seriously harms the environment and health. Sand and gravel aggregates with high mud content also have poor screening effects.

Method used

Design a wet screening and crushing device for sand and gravel aggregates, which integrates crushing and wet screening. During the crushing process, water mist is sprayed through a water distribution box and spray nozzles to adsorb dust, and a screen plate and a support plate are used in the screening chamber to separate sand and gravel from mud and water.

Benefits of technology

It effectively reduces dust pollution, improves production efficiency and screening accuracy, simplifies the process, reduces equipment investment and manual operation, and improves the separation effect of muddy sand and gravel aggregates.
