Abstract:With the continuous improvement of industrial automation level and control system reliability requirements, the role of accurate material level control is becoming increasingly prominent. Ore level gauges are widely used in many measurement fields due to their superior performance such as low maintenance, high performance and high accuracy, but the material level gauge in the market has different shapes and colors, and in a specific environment, it cannot achieve 100% safety and reliability. How to effectively control the material level of the mine in a specific environment, ensure the safety of equipment and facilities, and achieve a stable and reliable production process is of great significance. In this paper, the overflowing problems of ore bunker are studied, and a new mechanical ore bunker level device is designed to achieve accurate detection.
