Description

Lifting type steel ball replenishing device

Technical Field

The utility model belongs to the technical field of grind ore deposit, concretely relates to device is added to over-and-under type steel ball that simple structure, safe and reliable, long service life, convenient operation, low in labor strength.

Background

Along with the development of large-scale and diversified mines, less-grade and multi-metal associated refractory ores are more and more, in order to improve the recovery rate and grade of minerals, useful mineral elements and impurity monomers need to be dissociated by means of ore grinding and the like before ore dressing, and a ball mill is the main ore grinding equipment at present. The grinding effect of the ball mill is mainly completed by steel balls, the consumption of the steel balls is continuously increased in the production process, and the steel balls are required to be frequently supplemented in order to ensure the grinding efficiency.

At present, the ball mill mainly adopts two modes of manually replenishing steel balls and automatically replenishing equipment, wherein the manually replenishing steel balls is to lift and transport the steel balls to a ball replenishing port of the ball mill by a crane and then manually put the steel balls into the ball replenishing port, and the ball mill has the following defects:

(1) because the single steel ball has larger mass and more total amount, the efficiency of manually adding the steel ball is low and the labor intensity is high; especially for large mills, the labor intensity of operators is higher because the quality of the steel balls replenished every time is up to more than one thousand kilograms.

(2) The time is long, and many people are needed to cooperate, so that the normal operation of production is influenced, and certain personal and equipment potential safety hazards exist.

In the prior art, steel ball automatic equipment comprises a continuous ball feeding device and an intermittent ball feeding device. The continuous ball adding device transfers the steel balls in the guide groove into the ball conveying pipe one by one through the rotary ball claws, so that the purpose of adding the steel balls according to the requirement is achieved; and the steel ball in the guide groove is pushed into the ball inlet through a crank connecting rod mechanism, so that the ball is added as required. Although the continuous ball adding equipment can continuously or intermittently add balls according to the requirement, so that the filling rate of the ball mill is basically kept in the optimal state, because only one or one row of steel balls can be added each time, and the allowable variation range of the sizes of the added steel balls is small, the adding efficiency is low or even the requirement cannot be met for the adding requirements of various and large numbers of steel balls during the initial ball loading of the ball mill. The intermittent ball adding device is generally characterized in that a hinged turning plate is arranged at the bottom of a cylindrical container, or a conical baffle plate is directly arranged, and then a hanger rod which upwards penetrates through the cylindrical container is used for controlling the turning plate to rotate or the conical baffle plate to move up and down, so that the purpose of discharging steel balls in the cylindrical container from the bottom is achieved. But the hinged mode can impact the turnover plate in the ball loading and unloading process, so that not only the hinged joint is easy to damage, but also the single thin turnover plate is easy to influence the sealing of the small-diameter steel ball due to impact deformation, the potential safety hazard that the small-diameter steel ball falls off exists during hoisting, and the whole service life is limited; and because the existence of articulated junction, the board that turns over can not direct ground connection, consequently all need upwards pull the board that turns over through the jib during dress ball and during the temporary storage after dress ball, it is comparatively inconvenient to use. Although the conical baffle type structure can be directly grounded to avoid the defect of a hinged structure, no matter the conical baffle type structure or the hinged structure is adopted, the suspender is directly exposed and penetrates through the middle part of the cylindrical container, the suspender is easily damaged by the impact of the steel balls when the balls are loaded and unloaded, and the suspender is easily clamped by the extrusion between the steel balls after the balls are loaded and unloaded, so that the smooth ball unloading is difficult. Therefore, in order to overcome the above-mentioned defects, it is necessary to improve the existing automatic ball feeding device.
