The silo discharge device is used for storage and transportation in cement plants or related industrial settings. Its main function is to safely and efficiently unload and transport cement or other powdered materials from the bottom of the cement silo. These devices utilize automated control to ensure ease of operation and safety. They also allow for adjustable unloading flow while maintaining uniformity.
Darko can also customize according to user's requirements
1. Composition of a discharge device
- Slide gate valve
- Diverting box
- Pneumatic on-off valve
- Electric flow control valve
- Discharge chute, etc.
2. Working Principle
»During unloading, the bottom slide gate is opened manually or automatically, allowing the material to flow out under the influence of gravity.
»The electric flow control valve adjusts the opening to ensure a constant flow rate of the material.
»The material passes through the discharge chute into the downstream conveying system or bulk loader, directly loading onto trucks or entering the next production stage.
