Problems solved by technology

Since the loss of steel balls is indirectly reflected by the change of the operating current and power of the ball mill, there are many factors affecting the current and power such as the change of the mechanical damping of the ball mill and the wear of the liner of the ball mill, so this method cannot be realized. Accurate replenishment of lost steel balls

Embodiment Construction

[0019] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0020] As can be seen from the accompanying drawings, a method for adding balls to a ball mill of this program is characterized in that it comprises the following steps:

[0021] 1) Divide the continuous operation time of the ball mill into a time period T suitable for the production system time, where T is the length of each time period; the time period T is 1 hour or 8 hours or 12 hours or 24 hours .

[0022] 2) When starting a new time period, collect the production ore quantity Qw of the ball mill in the previous time period, and calculate the quantity Qqs that needs to be added in this time period according to the ore quantity Qw, Qqs=Qw×(Kg / tw)÷(Kg / q), where Qqs is the number of balls added in this time period, Kg / tw is the weight of balls consumed per ton of ore, and Kg / q is...

Abstract

The invention provides a ball charging method of a ball mill, which is capable of accurately tracking the ball consumption. The ball charging method can be used for collecting the quantity of produced minerals truly, and tracking the quantity of abraded steel balls accurately, so that the problem that ball blocking and ball clamping are difficult to prevent and solve generally in the ball charging process is solved, and steel balls lost in production can be supplemented stably and accurately.

Description

technical field [0001] The invention belongs to the technical field of mine beneficiation equipment control, in particular to a method for accurately tracking ball consumption and realizing adding balls to a ball mill. Background technique [0002] There are tens of thousands of mines of various types in our country, and there are billions of tons of ore dressing and grinding every year. In the process of beneficiation and grinding in mines, the steel balls in the ball mill are constantly worn out as the ore is eroded, and the lost steel balls need to be replenished. Therefore, in order to supplement the worn steel balls in production, quantitative addition of balls is usually performed manually. The impact of this operation mode is: due to human factors, the ball consumption cannot be accurately replenished, which affects the grinding efficiency; at the same time, adding the supplementary steel balls to the ball mill at one time disturbs the gradation of the ball diameter ...
