Background

In recent years, with the continuous and rapid development of economic society of China, the demand of sand for construction is continuously increased, and river sand resources cannot meet the market demand. At present, the processing of machine-made sandstone aggregate in China is widely applied to the construction fields of traffic, water conservancy, industry, civil buildings and the like.

Various problems exist in the rapid development process of the machine-made sand aggregate stone industry, for example, only the profit is paid attention to in the mining and crushing sand making links, and the environmental protection is not paid attention to; the performance indexes of the machine-made sandstone production equipment are uneven, and the produced sandstone aggregate is unqualified or unstable; many production enterprises do not have laboratories, the factory inspection and the provided qualification certificate specified in the national standard basically do not have the implementation, the sandstone quality is out of control, hidden troubles are buried in the engineering, and the like.

The technical quality indexes of the machine-made sandstone mainly comprise fineness modulus, particle grading, mud block content, stone powder content, needle flake particle content, harmful substance content, crushing value, firmness, chloride ion content and the like. Most quality indexes of the machine-made sand are related to the condition of the master batch and are stable, only fineness modulus, stone powder content, particle grading and needle flake particle content are closely related to processing equipment, and adjustment of equipment parameters or abrasion of consumable parts can change sand quality index parameters, so that for a large sand-stone aggregate production line, the equipment parameters need to be adjusted repeatedly and sand-stone material quality needs to be detected repeatedly during production, the quality index of finished products needs to be checked repeatedly every day of work to prevent unstable sand quality caused by equipment abrasion, and the most important parameter is the particle grading or the fineness modulus of the materials. At present, most of sandstone aggregate detection processes are processes of sampling, submission, detection, report and the like, a detection period needs 1 to 2 days (a factory in a laboratory has a short detection period), and the progress of equipment debugging is seriously influenced or batch unqualified finished products are caused.
