Abstract

The invention provides an ultrafine grinding system for blast furnace slag, which comprises an ultrafine powder mill (1), a powder concentrator (2), a screw feeder (3) and an oil hydraulic system (4), wherein the powder concentrator (2) is arranged in the ultrafine powder mill (1); the screw feeder (3) is connected with one side of the ultrafine powder mill (1); the oil hydraulic system (4) is connected with the other side of the ultrafine powder mill (1); the ultrafine powder mill (1) comprises a motor (1-1), a speed reducer (1-2), a grinding disc (1-3), a grinding roller (1-4), an air inlet (1-5) and an impurity discharging port (1-6); the speed reducer (1-2) is connected with the motor (1-1); the grinding disc (1-3) is arranged in the ultrafine powder mill (1); the grinding roller (1-4) is connected with the grinding disc (1-3); the air inlet (1-5) and the impurity discharging port (1-6) are formed on the lower part of the ultrafine powder mill (1); and the powder concentrator is a dynamic powder concentrator. The ultrafine grinding system provided by the invention is used for grinding the slag to a certain particle size and due to the excellent hydrating capacity, the superfine slag powder is utilized as a main material of cement products and a main mineral admixture of concrete, so that the strength and comprehensive property of the building material products are increased.

Description

technical field [0001] The invention relates to a superfine grinding system for blast furnace slag, which belongs to the technical field of machinery. Background technique [0002] Blast furnace slag is the tailings produced in the ironmaking process, and the reuse of tailings resources is the performance of SBM's support for high-efficiency and energy-saving mineral processing industries and the development of green mine economy. The ultra-fine pulverizer crushes the slag to a certain particle size through a closed grinding system. The ultra-fine slag powder has good hydration performance and becomes the main material of cement products and the main admixture of concrete, thereby improving the construction material products. strength and comprehensive performance. [0003] At present, there are problems such as high energy consumption and low production efficiency in the field of ultrafine grinding. Contents of the invention [0004] The purpose of the present invention...
