Method for quickly determining optimal gradations of ceramic grinding bodies of cement ball mill

Abstract

The present invention relates to a method for quickly determining the optimal gradations of the ceramic grinding bodies of a cement ball mill. The method comprises the following steps that: (1) a cement grinding system is calibrated before the ceramic grinding bodies are used; (2) the relative grindability of materials to be ground is measured; (3) materials to be ground for a libratory grinding test are selected; (4) a ceramic grinding body gradation scheme is designed; (5) the operation of the libratory grinding test is performed; (6) the yield of an industrialized grinding test is calculated according to the result of the libratory grinding test; (7) the feasibility of the gradation scheme is judged; (8) the use scheme of the ceramic grinding bodies is adjusted according to the inherent capacities of machining procedures; and (9) the gradations of grinding bodies in a second cabin in the industrialized grinding test are calculated according to the gradations of the grinding bodies in the libratory grinding test. With the method adopted, the optimal scheme for the gradation of the grinding bodies in the industrialized grinding test can be determined fast.

Description

technical field [0001] The invention belongs to the field of cement production and grinding, and relates to cement grinding system process calibration technology, material grindability measurement, cement fineness and particle distribution measurement technology, and mathematical statistics optimization method skills. Specifically, the present invention relates to a method for quickly determining the optimum gradation of the ceramic grinding body of a cement ball mill. Background technique [0002] At present, in the cement industry, the power consumption of cement production and grinding accounts for 60% to 70% of the energy consumption of the entire production process. In the situation of excess cement production capacity and increasingly fierce market competition, it is an urgent need for cement enterprises to improve their competitiveness by saving grinding energy consumption and reducing costs. Still dominant in the cement industry is the adoption of processes such as ...

Problems solved by technology

However, since the application of ceramic grinding bodies is in its infancy, the industry has not yet been able to summarize the use experience for different specific situations according to the differences in grinding process, material grindability, and cement varieties; especially, there is no simple and easy method. The method of quickly optimizing the grinding gradation has caused many companies to use ceramic grinding bodies, but they cannot quickly find the best solution that suits their own characteristics, and have to stop halfway, declaring failure, resulting in huge waste
