LSC type screw weighing feeder:

Screw weighing feeder is powdery, granular objects continuous conveyor, dynamic measurement, control to the production metering equipment material. According to the control after the screw conveyor material flow, flow process requirements, and realize the measurement management. Widely used in electric power, metallurgy, coal, chemical industry, port, building materials and other industries.

Equipment:scale body, gear motor, weighing sensor, speed sensor, control system and variable frequency speed regulation system.

Working principle.

Screw weighing quantitative feeder for feeding on quantitative bulk materials, the feeding process for spiral continuous feeding, feeder will come from the user to the bin or other feeding equipment, material conveying and weight measured by weighing bridge; at the same time is arranged on the end of the speed sensor speed detection of Leptospira; the weight signal and speed signal detected together into the 3000B/6000B weighing controller calculus processing, display the instantaneous flow and cumulant.

System features:

◆The sealing structure, reduce the dust outside
◆The dynamic measurement and spiral conveying material combination
◆ frequency stable operation, reliable (optional) Automatic measurement of the electronic calibration, automatic zero adjustment
◆ dynamic zero nonlinear tracking
◆ digital pulse generator, provides the reliable accuracy speed signal

Technical parameters:

◆The static measurement error: ≤ 0.5%;
◆The dynamic accumulation error: ≤ 1%;
◆ control accuracy better than 1%;
◆ instrument power: single phase 220V ± 10%, 50HZ;
◆ drag power: three-phase 380V ± 10%, 50HZ;
◆The use of the environment: temperature: -10 ℃ ~ +50 ℃
◆ humidity: 5% ~ 90% no condensation
