Main control box of mine automatic sprinkling dust device1. Scope of application
ZP127 mine automatic sprinkling dust device is mainly used for automatic sprinkling and dust reduction in coal mine roadway; it can provide automatic sprinkling and dust reduction for transportation roadway, belt conveyor transfer point and other places.
It is mainly used for automatic sprinkling and dust reduction at the transfer point of belt conveyor. In the touch mode, the host can realize the automatic spray function of touch. After touching the touch sensor, when the object touches the sensor, the device acts and starts spraying. After a certain time delay (the time is set by the user (20~1000 seconds)), the device stops sprinkling spray automatically.
