Belt type ball adding system

Abstract

The invention discloses a belt type ball adding system. The belt type ball adding system comprises a steel ball bin, a low-speed belt type feeding device and a quick belt type conveying device, wherein the inner side surface of the steel ball bin is at least provided with a partial inclined surface from top to bottom, and the lower end of the inner side surface defines a shrinking hole; the low-speed belt type feeding device is provided with a dropping end and a discharge end in a conveying direction; the dropping end is positioned below the shrinking hole to receive steel balls dropped from the shrinking hole, and convey the steel balls to the discharge end; and the quick belt type conveying device is positioned below the low-speed belt type feeding device to receive steel balls dropped from the low-speed belt type feeding device and transfer the steel balls to a mill one by one. According to the belt type ball adding system disclosed by the invention, operating speed of the low-speedbelt type feeding device and the quick belt type conveying device is gradually increased, so that the steel balls are superposed in multiple layers for being conveyed on the low-speed belt type feeding device, and are distributed in single layer on the quick belt type conveying device, and therefore, the steel balls are transferred to the mill one by one. Besides, the steel ball bin and the low-speed belt type feeding device can be designed to effectively avoid a ball blocking and arching phenomenon at the shrinking hole.

Description

technical field [0001] The invention relates to the technical field of mill ball addition, in particular to a belt type ball addition system. Background technique [0002] The existing underground belt-type ball feeding method generally adopts fan-shaped gates at the bottom of the underground steel ball warehouse, and the steel balls are transferred to the belt conveyor through the gate funnel. The belt scale is installed on the belt conveyor, and the steel balls are measured by the belt scale. Then add to the ball mill. This underground belt-type ball feeding method has the following disadvantages: first, the bottom of the steel ball warehouse is booing, and the gate is installed at the discharge port, which is easy to jam the ball, resulting in the steel ball warehouse cannot store steel balls, and the utilization factor is low; second, the intermittent type For feeding, the belt scale installed on the belt conveyor under the warehouse has no stable material pressure, and...

Problems solved by technology

This underground belt-type ball feeding method has the following disadvantages: first, the bottom of the steel ball warehouse is booing, and the gate is installed at the discharge port, which is easy to jam the ball, resulting in the steel ball warehouse cannot store steel balls, and the utilization factor is low; second, the intermittent type For feeding, the belt scale installed on the belt conveyor under the warehouse has no stable material pressure, and its measurement accuracy is too poor to achieve accurate measurement and addition of balls; thirdly, the amount of steel balls is controlled and adjusted through the fan-shaped gate at the bottom of the steel ball warehouse. The error is large, and the amount of balls per unit time is large, and the time for adding balls online is short, resulting in large fluctuations in the ball filling rate of the ball mill

[0003] The production practice of the above-mentioned underground belt-type ball adding method also shows that the balls are frequently jammed at the fan-shaped gate at the bottom of the steel ball warehouse, resulting in the loss of the storage function of the steel ball warehouse; the measurement error of the belt scale on the belt conveyor is too large, and the measurement is lost. significance
