Abstract

The invention belongs to the technical field of asphalt mixture production equipment, and particularly relates to a screen cloth system used for aggregate in an asphalt mixing plant. The system comprises a preliminary screening net which is aslant arranged along a horizontal direction; a fine screening component and a coarse screening component, which have an opposite direction with an inclinationdirection of the preliminary screening net, are arranged below the preliminary screening net in sequence, and the fine screening component and the coarse screening component are arranged in parallel.The screen cloth system used for the aggregate in the asphalt mixing plant can realize the quick screening of asphalt aggregate, the blending efficiency of asphalt is improved, and a small land is occupied.

Description

Technical field [0001] The invention belongs to the technical field of asphalt mixture production equipment, and particularly relates to a screen system for aggregates of an asphalt mixing plant. Background technique [0002] With the extensive development of various engineering constructions, the asphalt mixing plant as a key equipment for asphalt pavement construction has been widely used and mainly used. Its main function is to measure and mix materials such as sand and gravel, asphalt, mineral powder and other materials into asphalt mixture. According to the size of the nominal maximum particle size, it can be divided into extra-coarse, coarse-grain, medium-grain, fine-grain, and sand. Type asphalt mixture. The existing container-type asphalt mixing equipment mainly includes: cold material system, drying system, dust removal system, powder system, screen system, hot aggregate bin, asphalt pipeline system, hot aggregate elevator, metering system, mixing The system and contro...
