[0002] The single-cylinder cone crusher can be used to crush large pieces of materials into fine particles, improve the utilization efficiency of materials, and meet different manufacturing and demand requirements. It is particularly suitable for materials with characteristics such as impact, friction, and erosion, and is widely used in fields such as food, household crushing equipment, mineral crushing equipment, coal crushing equipment, and building material crushing equipment. Its working principle is that the material enters from the inlet of the cylinder body and is broken inside the cylinder body as the reverse pendulum swings. The crushed material is sent out through the outlet of the cylinder body. It runs smoothly, has a compact structure, and has a high crushing efficiency.

[0003] Due to the large number of control devices in the single-cylinder cone crusher and the need to meet high dynamic response requirements to adapt to rapidly changing working loads, integrate and process data from various sensors to achieve real-time monitoring of the device, provide electrical protection and safety to prevent equipment damage and accidents, and maintain the stability and reliability of the electrical circuit in a harsh working environment, there are multiple difficulties in the design of the single-cylinder cone crusher control device.
