System and method for improving stone surface properties

Abstract

The invention discloses a stone surface performance improvement system and a stone surface performance improvement method. The system comprises a drying bin, a storage agent bin, a modification bin, an air heater, a discharge chute, a stone sampling device and a control device, wherein the modification bin is a slightly tilting single-shaft horizontal stirring cylinder, an entrance gate is arranged at the upward tilting end of the horizontal stirring cylinder, an exit gate and two air ports are arranged at the downward tilting end of the horizontal stirring cylinder, a sampling gate is arranged at the bottom of the horizontal stirring cylinder, a main shaft is fixed in the modification bin, detectors and modifier nozzles are distributed on the main shaft, and a transmission gear for driving the overall rotation of the modification bin is arranged on the outer wall of the modification bin. According to the system and the method disclosed by the invention, the surface modification effect of stone can be estimated in real time when a surface modifier which is subjected to atomization, foaming and other treatment is mixed with the stone, and then various parameters are adjusted according to the modification effect, so as to achieve the purpose of sufficiently improving the surface performance of the stone without affecting continuous conveying of the stone, so that the requirement for large-scale engineering construction is met.

Description

technical field [0001] The invention relates to a system and a method for improving the surface performance of stone materials, in particular to a system and a method for improving the surface performance of stone materials at a large-scale construction site, and belongs to the technical field of road construction machinery. Background technique [0002] Stones used in road construction today must meet a number of raw material performance requirements. However, due to the unqualified individual indicators of some stones, such stones cannot be used even if other performance indicators are excellent, and further regions need to purchase stones that fully meet the requirements. This has led to high stone prices, increased haul distances, and an over-reliance on and exploitation of certain types of stone. It not only increases the construction cost, but also causes environmental damage due to over-exploitation. For example, although acidic or neutral stones have good mechanica...
