Technical Field

The invention relates to the field of superfine grinding of non-metallic ores, in particular to a high-temperature and high-pressure non-metallic mineral spray gun crushing device.

Background

The non-metallic ore ultrafine grinding technology is a new mineral processing technology developed along with the development of modern high technology, new material industry, the technical progress of the traditional industry, the comprehensive utilization of resources and the like, and has important significance and influence on the development of new industry and the upgrading and adjustment of the structure of the traditional industry. The superfine non-metallic mineral powder has the characteristics of fine granularity, relatively uniform quality and high surface activity, and also has the properties of high chemical reaction speed, large adsorption quantity, high solubility, low sintering temperature and the like, so that the demand of the global superfine non-metallic mineral powder material and the superfine non-metallic mineral powder product are rapidly increased in recent 30 years. However, the traditional ultrafine grinding equipment such as an air flow mill, a mechanical impact type ultrafine mill, a stirring mill, a sand mill and the like cannot well protect mineral crystals, and the traditional ultrafine grinding equipment has general working efficiency, needs a large amount of operating cost and occupied area, and can generate environmental pollution problems such as mineral dust and the like.

The research shows that: the tensile strength of the solid binder is much smaller than the compressive strength, and the tensile strength of the non-metallic ore is dozens of times smaller than the compressive strength. The reason for this is that the inter-granular molecular forces decrease with increasing load when the ore is tensioned, and increase with increasing load when compressed. Particularly, the binding force is weak in the place where minerals and rocks are bound. Furthermore, because of the characteristic of small internal tension of the non-metallic mineral along the grain boundary, the non-metallic mineral is easy to break at the grain boundary to separate the mineral, which creates favorable conditions for the non-metallic mineral to have better dissociation degree on the aspect of keeping the natural particle geometry. Based on the analysis, the theoretical starting point of the nonmetal mineral spray gun crushing device based on high temperature and high pressure designed at this time is standing. The device designed at this time is simple in structure, high in ore crushing efficiency and capable of achieving full-closed crushing, almost avoids flying of ore dust, keeps the original crystal structure of ore, avoids the over-grinding phenomenon, facilitates next-step operation, reduces investment and saves occupied area.
