An online monitoring system for quality control of mining sand and gravel aggregates

Abstract

The invention discloses an on-line monitoring system for quality control of mining sand and gravel aggregates, comprising a main controller, a server, and an executing mechanism. A screening device fixed on the frame body; the crushing device includes a crushing barrel fixed on the frame body, a backing plate fixed on the inner wall of the crushing barrel, a squeezing plate whose upper end rotates and is arranged on the crushing barrel, and one end rotates A first rotating rod set on the extrusion plate, a second rotating rod set on the inner wall of the crushing barrel at one end, and a connecting rod at the other end of the first rotating rod and the other end of the second rotating rod respectively rotated at both ends, The first rotating shaft which is rotatably arranged on the connecting rod, and the driving shaft which is deviated from the axis of the first rotating shaft and is fixedly arranged on the first rotating shaft and is rotatably arranged on the crushing barrel at both ends.

Description

technical field [0001] The invention relates to the technical field of sand and gravel processing, in particular to an on-line monitoring system for quality control of mining sand and gravel aggregates. Background technique [0002] In recent years, with the rapid development of my country's economy and the rapid development of the construction industry, the demand for sand and gravel aggregates has increased year by year. There is a direct relationship between size and crushing, that is, crushing can directly affect the particle size of sand and gravel. After crushing mining sand and gravel, it needs to be screened. During screening, the filter needs to vibrate, which will generate large noise and affect the surrounding environment. At the same time, it is easy to block the filter. The filter needs to be shut down to clean the filter, resulting in low efficiency of sand and gravel aggregates. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the pr...

[0002] In recent years, with the rapid development of my country's economy and the rapid development of the construction industry, the demand for sand and gravel aggregates has increased year by year. As long as the quality control of mining sand and gravel aggregates is to monitor the particle size and humidity of sand and gravel, the particle size of sand and gravel The size is directly related to the crushing, that is, the crushing can directly affect the particle size of the sand and gravel. Mining sand and gravel need to be screened after crushing. The filter needs to be vibrated during screening, which will generate large noise and affect the surrounding environment. At the same time, it is easy to block the filter screen, need to shut down to clean the filter screen, resulting in low aggregate efficiency
