Machine-made sandstone production workshop coarse aggregate flushing and pitch diameter online monitoring method

Abstract

The invention provides a machine-made sandstone production workshop coarse aggregate flushing and pitch diameter online monitoring method. The method comprises the following steps: presetting the balance weight ratio and the allowed deviation range of each size fraction of coarse aggregate in an intelligent control center; conveying the coarse aggregate to a flushing detection sieve through a feeding metering sealing-tape machine, and screening and grading the particle size; conveying the aggregate of each size fraction to a finished product conveying sealing-tape machine through different metering sealing-tape machines to be mixed and then warehoused; collecting weighing data of the feeding metering sealing-tape machine and all the metering sealing-tape machines after screening in real time by the intelligent control center; calculating the weight ratio of the coarse aggregate of each size fraction and comparing the weight ratio with a preset value, and warehousing the aggregate if the weight ratio is qualified; and if the weight ratio exceeds the allowed deviation range, giving an early warning through the intelligent control center and notifying an operator to perform processing. Intelligent control over the grain size and size fraction and the weight ratio of the coarse aggregate for warehousing is achieved, it is ensured that the gradation of the warehoused coarse aggregate meets the requirement of the next procedure, and a foundation is laid for achieving the overall machining control process of high-quality machine-made sand.

Description

technical field [0001] The invention belongs to the technical field of machine-made sand and gravel processing, and in particular relates to a method for washing coarse aggregates and on-line monitoring of the median diameter in a machine-made sand and gravel production workshop. Background technique [0002] Mechanism-based sand and gravel processing processes stones into aggregates of different particle sizes step by step from coarse crushing, medium fine crushing, and ultra-fine crushing. After the multi-layer environmental protection sieve is graded and graded, the coarse aggregate particle shape and particle size distribution produced have met the quality requirements of high-quality machine-made sand and gravel. However, in the existing technology, the diameter of the coarse aggregate is not monitored before it is put into storage, and effective quality control methods are lacking. In order to realize adjustable and controllable high-quality machine-made sand processin...

Problems solved by technology

However, in the existing technology, the diameter of the coarse aggregate is not monitored before it is put into storage, and effective quality control methods are lacking. In order to realize adjustable and controllable high-quality machine-made sand processing, the mineral material is crushed in multiple stages to ensure its If the particle size and particle size of the final product are controllable, the particle size and particle size of the previous process must be controlled step by step. If the mass ratio of each particle size fluctuates, there will be deviations in the crushed particle size and particle size of the subsequent process, resulting in Quality problems affect the crushing efficiency at the same time, and cannot meet the processing requirements of high-quality machine-made sand and gravel
