1. Constant value control: For the crusher load control is a typical constant value control system. For different types of materials, manually set different crushers to verify the load. When the set current (input amount) is constant, the controller load (output) will be consistent with the set current by controller adjustment.
2, pure lag link: the so-called pure lag, the popular point is that when the pulverizer feed flow changes, the pulverizer operating current needs to lag some time before the corresponding change. According to the inherent characteristics of the crusher equipment and the choice of actuators, the pure lag time is also different. From the perspective of automatic control, the shorter the pure lag time, the faster the control response speed, and the more stable the control object of the system.
3, the main parameters and functions
(1) Control range 0 to 100% FS (arbitrary setting).
(2) Control accuracy 2% to 8% FS.
(3) The manual setting current and the actual operating current can be displayed in real time.
(4) There are two modes of manual and automatic control, and there is no disturbance when switching.
(5) Implement sound and light alarm and real-time processing for material shortage and overload.
(6) Interlocking of equipment working conditions, interlocking of fan and pulverizer operation and feeding mechanism.
