Method for automatically adjusting division ratio and division stroke in preparation process of ore sample through weighing

Abstract

A method for automatically adjusting the division ratio and the division stroke in the preparation process of an ore sample through weighing is characterized in that the method comprises the following steps: 1, weighing: weighing the ore sample in a hopper, and importing the weighed mass data of the ore sample to a programmable controller through a weighing sensor; 2, calculation programming of the programmable controller: calculating by the programmable controller according to the weighed mass data of the ore sample in step 1 to obtain the division ratio which is the ratio of a residual sample mass to a material mass; and 3, controlling the division stroke. The method has the following advantages: 1, the automatic adjustment of the division ratio and the division stroke of a division device by the programmable controller according to the mass data of the ore sample by weighing the material substitutes artificial calculation and adjustment, and the sample preparation is representative; 2, the division precision is high, the division deviation is small, and the influences of artificial factors are avoided; 3, the working efficiency is improved, the preparation time of the sample is shortened, and the labor intensity of a worker is mitigated; and 4, the method can be combined with other sample preparation programs to realize an unattended combined automation purpose.

Description

technical field [0001] The invention relates to a preparation method of an ore sample, in particular to a method for automatically adjusting the reduction ratio and the reduction stroke in the preparation process of the ore sample by weighing. Background technique [0002] The preparation of ore samples needs to obtain materials with specified particle size and specified quality. The materials to obtain specified quality are currently obtained by shrinking equipment. The existing shrinking method is to use shrinking equipment for shrinking. Manual adjustment, manual adjustment is mainly carried out manually according to the scale indication of the preset reduction ratio on the reducer. Since the quality of the materials to be sampled is different, in order to obtain a representative sample, the materials to be sampled must be weighed Finally, manually calculate the reduction ratio, and then manually adjust the reduction device of the reduction device to achieve the reduc...

AI Technical Summary

Problems solved by technology

There is a large error in manual adjustment, resulting in a large deviation of the reduction ratio, and when the reduction ratio and the reduction stroke need to be adjusted, the device needs to be opened for adjustment, which has hidden dangers and low work efficiency; in addition, the adjustment of weighing and reduction ratio 1. The work of feeding materials cannot be carried out at the same time, there are many working links, long sample preparation time, and high labor intensity of operators, and the goal of unattended joint automation of sample preparation procedures cannot be realized
