Direct measuring device and direct measuring method for loading capacity of grinder equipment

Abstract

The invention discloses a direct measuring device for the loading capacity of grinder equipment. The device comprises a laser ranging device with an angle ruler, and a controller, wherein a signal output end of the laser ranging device is connected to a signal input end of the controller through an RS232 interface; an transmission end of the laser ranging device is aligned with the interior of the grinder along the vertical face of the axis of the grinder; and the transmission end is higher than the highest loading position in the grinder. Accordingly, the invention also provides a direct measuring method for the loading capacity. The fixed point height of a backing material in the grinder is directly measured by the laser ranging device so as to measure the loading capacity in the ball grinder and effectively and intuitively prevent the grinder from being expanded; and under the condition of stable feeding, the problem of grinding efficiency reflected by high and low material change can be discovered so as to provide a good foundation for the stable work of the grinder.

Description

technical field [0001] The present invention relates to a technique for direct measurement of loading of mill equipment. Background technique [0002] Metallurgy, electric power, building materials, cement ceramics, chemical mining and other industries all involve the process of crushing mined ores and further grinding and subdividing them. In order to meet the feed requirements of subsequent processes (such as flotation), a large amount of fine ore needs to be ground to -200 mesh, which accounts for 60%-70% of the requirements. Under the continuous rotation of the grinding machine, the internal steel balls continuously hammer and grind fine ore. At this time, part of the fine ore enters the classification process from the discharge port, and part of it is mixed with the new material entering the mill to continue grinding, thus completing the continuous operation process. During this process, it is necessary to consider the amount of discharge from the mill, the amount of ...

Problems solved by technology

However, there is a measuring device for coal pulverizers in China, which can simulate the actual material level by measuring the coal temperature at multiple points at the coal inlet, substituting it into the algorithm configuration mode to form a second function and then summing it up. However, in the coal grinding process Under the influence of many factors, the formation of such a single-value correspondence requires more practical proofs

[0011] The key to technological progress is whether the internal dynamic charging height can be directly and continuously measured. At present, there is no new loading measurement device on the grinding machine (ball or rod mill, self-grinding) in the world and domestically.
