Device and method for detecting ball stones in air bag type ball mill

Abstract

The invention provides a device and a method for detecting ball stones in an air bag type ball mill, and relates to the technical field of a ball mill detection device. The device comprises a ball mill cover (2) at an opening of the ball mill (1), and is characterized in that the lower part of the ball mill cover (2) is provided with a protective head (3) which can be inserted into the opening of the ball mill (1); a cavity structure is formed in the protective head (3); a detection head (4) is arranged at the lower side in the cavity, and the bottom end of the detection head extends into the ball mill (1); an air bag (7) is fixedly arranged above the detection head (4); the upper part of the air bag (7) is connected with a gas pressure detection sensor (10) outside the ball mill cover (2) and an air bag inflating device; the gas pressure detection sensor (10) is connected with a signal processing device. The method for detecting the ball stones in the air bag type ball mill comprises the steps of calibrating, acquiring a data list, and then detecting the amount of ball stones in the ball mill. After the device and the method are adopted, the amount of the ball stones can be detected, a data basis is provided for adding ball stones, and the amount of the ball stones in the ball mill is stable.

Description

technical field [0001] The invention discloses a ball stone detection device and a detection method inside an airbag type ball mill, relating to the ball mill detection device and the technical field. Background technique [0002] The ball mill is the key equipment for crushing and grinding after the ground material is crushed. It is the most important high-fine grinding production equipment in industrial production enterprises. During the working process of the ball mill, the main working medium inside the ball mill is ball stones. The ball stones in the ball mill are gradually lost and reduced while grinding materials. When the ball stone loss reaches a certain level, it will affect the grinding efficiency of materials and produce materials. If the grinding particles are too large and the product is unqualified, this will affect the follow-up work and ultimately affect the grinding efficiency of the ball mill. When the ball stones are worn out, in order to prevent the abo...

Problems solved by technology

However, in the process of realizing the present invention, the inventor found that in the prior art, each research institution reasoned and estimated the amount of ball stones by means of simulation or guessing, which was much different from the actual weight of ball stones inside the ball mill, which directly led to Adding too little or too much ball stone can not make the ball mill in the best working condition, which affects the grinding efficiency of the ball mill

The application number is: 201210060289.7, the name of the invention is: the ball mill internal ball stone group and massive mineral material dynamic distribution detection system and method of the invention patent application, the application number is: 201210059870.7, the invention name is: ball stone group and mineral material inside the ball mill Invention patent application for dynamic distribution detection system and method, application number: 201210060196.4, invention name: Invention patent application for detection system and method of ball stone group and hard block mineral material distribution inside the ball mill, and application number: 201210060132.4, In the invention patent titled: Dynamic Distribution Detection System and Method of Steel Ball Groups Inside Ball Mills, a device and method for detecting ball stone groups inside a ball mill are disclosed, but the device can only detect the dynamic distribution of ball stone groups, but cannot Real-time detection of the number of balls inside the ball mill makes it impossible to calculate how many balls need to be added to the inside of the ball mill

The inventor believes that the reasons for the above problems are that, in addition to the complicated working conditions of the ball stones inside the ball mill, which are difficult to measure, the main reason is that there is no special ball stone detection device inside the ball mill for scientific detection, and there is no establishment of using the internal ball stones of the ball mill. An effective method for detection by the ball stone detection device
