Knife Gate Key Specifications

Actuation

Manual hand wheel, pneumatic cylinder, or electric motorized actuator for automated process control in cement plant material handling circuits.

Sealing Type

Standard and low-leakage seals for dry bulk materials; inflatable zero-leakage seals available for fine cement powder applications requiring dust containment.

Seating Configuration

Hard seated (metal-to-metal) for high-temperature clinker lines; soft seated (polymer-lined) for ambient-temperature cement and raw meal applications.

Port Shape

Square and rectangular ports for chute integration; circular ports available for pipeline connections in pneumatic conveying systems.

Body Material

Mild steel fabricated body with optional Hardox 450/500 wear plates for abrasion resistance in clinker and raw material handling.

Size Range

Available from 150 mm to 1200 mm port sizes to suit various material flow rates in cement production lines.

Industrial Applications

Clinker Cooler Discharge
Installed at clinker cooler outlets to regulate hot clinker flow to the cement grinding mill, with hard-seated configuration to handle temperatures up to 200°C.
Raw Meal Silo Extraction
Positioned at silo discharge points to control raw meal feed rate to the preheater tower, ensuring consistent material flow and preventing bridging.
Cement Packing Plant Feed
Used at packing plant hoppers to provide on/off shutoff for cement flow to rotary packers, with dust-tight sealing to maintain a clean working environment.
