Dosing Equipment for Dust Collector, Limestone/Caco3 Precoating Dose Machine, Calcium Carbonate Feeder, Automated Precoat Powder Dispenser

The compressed air supply is via a connection nozzle (8) located on the lower left side of the device. The compressed air interval is controlled by a solenoid valve (9), and the flow rate is regulated by a throttle valve (10). The defined dosing mode (pre-coating, inerting, initial dosing) is set in the logic module of the switch and control unit (11), while the operating mode ("Auto/Manual/Zero") can be selected via the switch (12) Set on switches and controls. Automatic operation means: the operation of the dosing device with dust collector is blocked electrically. While in manual operation, the dosing device can be operated independently.

The feed material level is monitored by a sensor (13). When the minimum level is undershot, the "device empty" indicator light (14) lights up and activates the signaling contact in the switching device. After filling the device, the operational readiness of the device is restored by pressing the "Fill" (15) acknowledgment key. When filling the dosing device, the dosing fan is activated via the container lid push button switch (16), so that spilled dust is immediately sucked up. At the same time, the dosing of compressed air interval control is interrupted during the filling process.

In the "Inerting" operating mode, the desired dosing quantity can be set via the pause time of the dosing interval. The compressed air blowing time must always be set to a fixed 5 seconds. With the aid of the dosing program described above, the dosing pause time for the desired dosing quantity can be determined.
