GL-Series Tubular Drag Chain Conveyor Specifications and Capacity

Read the Reference Conditions First

The LIYOU GL-series table states capacity in cubic metres per hour. Its reference conditions are a bulk density of 1 t/m³, chain speed of 0.3 m/s, filling factor of 0.5 and conventional dry powders. These conditions belong with the model data; removing them makes the capacity figures misleading.

Match Tube Size to the Material Stream

The brochure associates GL89 with small-volume and pilot-scale duties; GL108/133 with small-scale batching and starch; GL159 with grain, calcium powder, plastic pellets and resin powder; and the larger entries with mineral powder, cement, fertilizer and other bulk powders. These are application examples, not fixed capacity ratings for each material.

m³/h and t/h Measure Different Things

Mass flow (t/h) = volume flow (m³/h) × bulk density (t/m³).

At the stated reference density of 1 t/m³, the GL159 table value of 10 m³/h corresponds arithmetically to 10 t/h. That conversion does not establish a guaranteed 10 t/h for every powder: a lower bulk density gives less mass for the same occupied volume, and material flow and route loading can also change the achieved volume rate.

Distance, Lift and Motor Power Describe the Duty

The maximum horizontal and vertical figures are catalogue limits, not confirmation that both maxima are available together on every layout. The complete conveying and return circuit, number of bends, material density and feed loading determine the configured duty.

Motor power is given as a range, from 1.1–11 kW for GL89 to 5.5–30 kW for GL273 and GL325. It is not a single standard motor assigned to each model. Increasing motor power does not change the tube diameter or remove an inlet blockage.

Filling Factor Is Not a Universal Setting

The reference table uses a filling factor of 0.5. The brochure also describes reduced filling in vertical sections to limit material fallback. A combined horizontal and vertical route needs its own loading arrangement instead of assuming the same fill condition everywhere.
