DEL / DEM Series Weigh Feeder / Quantitative Feeder

The DEM/DEL quantitative feeder is a new generation product manufactured by our company using technology imported from Schenck (Germany). It features high metering and control accuracy as well as stable performance. Its rational and optimized design enables operation under harsh working conditions. By adopting corresponding structures and hopper types according to specific situations, it economically solves many difficulties in material feeding. It is widely used for quantitative conveying of granular materials in industries such as building materials, metallurgy, steel, chemical, coal, and ceramics.

Weighing Unit Composition:

The DEM/DEL variable frequency speed control quantitative feeder mainly consists of a belt feeder and a weighing device.

(1) Variable Frequency Speed Control Quantitative Feeder: Conveyor support, endless skirt belt with no splice, variable frequency speed control motor, frequency converter, etc.

(2) Electronic Weighing Device: Includes industrial microcomputer, speed sensor, and high-precision load cell.

Features:

• Adopts our company's high-performance electronic belt scale, ensuring metering accuracy and long-term stability

• Variable frequency speed control, smooth operation, energy saving, and meets requirements for open-loop or closed-loop flow adjustment on site

• Comprehensive alarm system enables timely detection and resolution of faults such as material blockage, material shortage, overload, and belt misalignment

• Uses high-temperature resistant belt for long service life in harsh environments

• High-resolution load cell with 0.1mm displacement ensures accurate measurement values

• High-resolution digital pulse speed sensor ensures accurate speed values

• Automatic gravity tensioning device ensures constant belt tension, preventing belt slip and excessive tension

• Automatic belt tracking device prevents production interruptions caused by belt misalignment

• Plow scraper clears debris from the lower belt to prevent damage to the belt from debris between the belt and rollers

• Scrapers on both inner and outer sides of the belt prevent material buildup and belt weight changes

• Belt replacement is easy without assistance, simplifying maintenance

• Drive and driven rollers use self-aligning bearings, making installation and adjustment very convenient

• Actual feeding accuracy for various bulk materials is better than ±0.5% of the set feed rate

• Feed rate range: approximately 50kg/h to 2000t/h

• Belt width: 500mm to 1800mm

• Roller center distance: 1000mm to 8000mm; plug-in system allows dimensions to be customized according to user requirements

• Output interfaces: multiple options available, can connect to DCS system

• Ambient temperature: Scale body -10°C to +60°C; Instrument -10°C to +45°C

• Weighing frame uses high-strength rectangular tubes, offering high rigidity and good stability

• Shaft-mounted gear motor features low vibration and high stability

• Automatic belt tensioning device ensures constant belt tension, guaranteeing metering accuracy

• Automatic belt tracking device prevents production interruptions caused by belt misalignment

• Special structure weighing idler with high-precision bearings features low radial runout, smooth rotation, and high stability

• Lightweight belt or polyester belt offers good flexibility and low scale body tare weight

• Speed measuring device is mounted on the driven roller for accurate speed tracking

• For lower flow rates, a stepper motor drive can be used, offering accurate speed tracking and low vibration
