Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a wet screening machine for processing asphalt concrete raw materials. Background Technique

[0002] The production raw materials of asphalt concrete include sand and gravel, asphalt, stone powder and various additives. During the processing of asphalt concrete, the ratio of asphalt and cement needs to be strictly controlled, otherwise it will affect the final performance and service life. In addition, since asphalt itself is toxic, attention needs to be paid to environmental protection and safety issues during processing. At this time, a vibrating screening machine is required. A wet screening machine is a device used for classifying and screening solid particles, mainly used in industries such as mining, metallurgy, and chemical engineering. It can achieve particle classification and screening by controlling the water flow rate and pressure on the conveyor belt, effectively separating materials of different particle sizes, improving production efficiency and reducing waste.

[0003] The existing wet screening machines for processing asphalt concrete raw materials do not have efficient screening, and the accuracy may be affected. Due to the large differences between particles, some errors may occur during the screening process. These errors may lead to inaccurate screening results, affecting subsequent processing and use. During this process, some large-volume particles may leak into the next process during the screening process, thus greatly reducing the practicability of the equipment. At the same time, when larger-volume objects flow to the next process, it will cause damage to the machine, and on-site operations cannot continue, also reducing the working efficiency of the equipment.
