Abstract

The invention relates to a steel ball adding device of a ball mill. An inclined steel plate is welded at the bottom of a hollow square iron box which is formed by welding four vertical steel plates; the inclined steel plate passes through a lower opening of the vertical steel plate on one side for discharging balls; the inclined steel plate is welded with two lateral vertical steel plates and a horizontal steel plate to form a ball discharge chute; a horizontal shaft is arranged on the side for charging balls; rolling bearings arranged at two ends of a horizontal shaft are arranged at the small ends of lateral plates of fan-shaped gates on two sides; a fan-shaped gate in sliding fit with the outlet of the ball discharge chute is welded with the large ends of the lateral plates of the two fan-shaped gates on two sides; and a balancing weight is arranged at the tail end of a gate handle which is connected with the lateral plates of the fan-shaped gates to form a whole body. The device can be used for adding steel balls with small labor intensity and at high speed, and is high in work efficiency; as the fan-shaped gates only bear the lateral pressure of the steel balls, the lever-type gate handle with the balancing weight and a limiting block can be easily opened or closed, and the operation is safe and reliable; the output speed and quantity of steel balls can be controlled by the opening degree of the fan-shaped gates, and thus the steel balls which are discharged by inclining the chute are prevented from smashing a feeding opening of the ball mill.

Description

technical field [0001] The invention relates to auxiliary equipment and technology for mining and stone crushing industries, in particular to a ball mill steel ball adding device and a method for adding steel balls. Background technique [0002] The daily operation of ball mills in mining, cement and other stone crushing industries will produce steel ball loss, and a sufficient number of steel balls must be added in each shift. The added weight of steel balls varies from tens of kilograms to several tons depending on the size and processing capacity of the ball mill. At present, the process of adding steel balls is to hoist the iron box full of steel balls from the steel ball stacking place to the feed port of the ball mill, and manually pick out the steel balls from the iron box and put them into the feed port of the ball mill; there is labor intensity. Large size, slow speed of adding steel balls, and low work efficiency. The utility model patent ZL201320814228.5 disclose...
