Nano mud production method

Abstract

The invention relates to the field of slurry manufacture, in particular to a manufacturing method for nanometer slurry. The method comprises the following steps: manufacturing Portland cement into cement slurry; leading the cement slurry into a slurry storage groove in the side, near a static grinding disc, of a movable grinding disc through a slurry accessing pipe and the static grinding disc of R&D equipment; rotating the movable grinding disc to enable the Portland cement slurry to move and flow outward from the slurry storage groove through centrifugal force; conducting grinding through friction between the movable grinding disc and the static grinding disc; manufacturing the Portland cement slurry into superfine cement slurry to enable the granularity of the cement slurry to achieve or surpass a nanometer slurry standard. According to the invention, the stirred Portland cement slurry accesses the slurry storage groove through the slurry accessing pipe, is grinded through the friction between the movable grinding disc and the static grinding disc, and is manufactured into the superfine cement slurry; the manner is simple to operate, low in cost and high in grinding rate.

Description

technical field [0001] The invention relates to the field of mud production, in particular to a method for making nano mud. Background technique [0002] The grouting reinforcement and water blocking industry is to press the grouting material into the primary and secondary cracks and voids in the formation or buildings through the grouting pump to press the cement slurry or clay slurry, ultra-fine cement slurry, and chemical slurry. Make the injection area or injection body achieve the purpose of reinforcement and water blocking. [0003] General grouting projects, such as: karst, rock formation fissures, rock formation structure, structural fissures, rock formation collapse, conglomerate layers and other karst fissures developed rock formations and unimpeded water gushing channels, etc. During the implementation process, the commonly used grouting materials are: ordinary cement, clay mud , ultrafine cement, chemical pulp. [0004] Special grouting projects, such as: rock ...

AI Technical Summary

Problems solved by technology

[0005] The current chemical grout generally has a relatively complicated formula, which leads to higher prices, and most of the chemical grouting materials are polluted; the current ultra-fine cement is commonly produced, and the problem of low grinding efficiency makes the ultra-fine cement Increased production costs and higher prices
