Description

technical field

[0001] The invention relates to the technical field of coal screening and separation, in particular to a multifunctional screening device for coal mines. Background technique

[0002] With the significant progress made in the independent innovation research of my country's intelligent coal mining technology and equipment, the device has achieved good application results in the coal mine production process, and the automation and unmanned production have been initially realized in many stages of coal production. At the same time, intelligent, high-yield and high-efficiency coal mines put forward higher requirements for coal mine processing systems, which require higher efficiency of coal mine processing systems, fewer related operators, and stronger informatization capabilities. Screening requires the use of screening devices. When the existing coal mine screening devices are in use, firstly, the screening process is prone to overload, which reduces the servic...
