Embodiment Construction

[0029] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0030] Such as figure 1 As shown, this embodiment includes a cone crusher 1, an ore bin 2, a hydraulic drive device 3 at the lower ore mouth, a feeding belt 4, an ultrasonic material level sensor 5 and a programmable logic controller 6 (ie, a material level controller), Among them: the ore in the ore bin 2 falls from the ore bin 2, and falls on the ore feeding belt 4 under the action of the hydraulic drive device 3 at the lower ore mouth, and the ore feeding belt 4 transports the ore to the cone crusher 1 for crushing; The level sensor 5 is set on the top of the machine cavity of the crusher 1 to detect the materi...

Abstract

The invention discloses device and method for automatically controlling the choke feed of a conical crusher. The device comprises an ultrasonic level sensor, a programmable logic controller and a monitoring computer, wherein the programmable logic controller comprises an analogue input module, a CPU (Central Processing Unit) module and an analogue quantity output module and is taken as a control core; by using a model predicting control method for adjusting and controlling, the fully-automatic adjustment of feeding ore and crushing can be realized, the defect of manual operation can be avoided, the crushing efficiency can be improved, the service life of the crusher can be prolonged, the energy consumption can be reduced and the production benefit can be increased; and by using the monitoring computer for monitoring in real time, work parameters and index parameters of the programmable logic controller can be modified on line and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a real-time detection and control device and method for ore feeding and crushing working conditions of a crusher, in particular to an automatic control device and method for a cone crusher full of ore feeding. Background technique [0002] The crushing process is an important part of the mineral processing process. The main equipment is the crusher, which requires large equipment investment, high energy consumption, high use and maintenance costs, and the production efficiency of the crushing system directly affects the production cost and economic links of the entire mineral processing plant. In recent years, although a variety of foreign high-performance crushers have been introduced into China, most of the concentrators have not introduced them together with the equipment due to economic reasons because of the high price of the automatic ore feeding control system matched with the models. Therefore, in the past, the control ...
