Gravimetric Loss-in-Weight Feeders

The D-DW-1 systems excel in dosing fine to granulated bulk materials accurately across low to mid-range capacities. A separate AC motor controls the agitator and screw for steady material flow. The screw’s RPM adjusts based on preset values and bin weight, ensuring desired dosing capacity.

Best for: Cement, Gypsum
Typical materials: Dry additives

Standard Features:

• Ultra-sensitive load cell
• Custom-designed screw & agitator
• Durable steel exterior
• Completely closed system
• Dual AC motor config.
• Pre-bin (optional)
• Pre-filling discharge device (optional)

Specifications:

• Capacity: 10 kg/hr – 2,000 kg/hr
• Accuracy: +/- 0.5%
• Screw diameter: 20 mm – 140 mm
• Bulk density: 300 kg/m³ – 2,500 kg/m³
• Granulation: dusty to fine-grained
• Adjustment range: 1:10 (upgradeable up to 1:50 with feedback-encoder)

Depending on the set value and on the loss of weight within the weighing bin the speed revolution of the screw is controlled so that the dosing capacity corresponds exactly to the set value. Our LIW feeders are mounted onto a solid steel frame in order to ensure the stability required for a high-precise measuring. LIW feeders can also be supplied according ATEX rules, on request.
