JASUNG PMSM Cement Industry Applications
JASUNG permanent magnet synchronous motors (PMSM) provide advanced drive solutions for cement production equipment, delivering significant energy savings and operational reliability across multiple applications.
Key Applications in Cement Plants Hoister Systems
JASUNG PMSM technology enables direct drive operation for hoisters, eliminating the need for gear reducers and fluid couplings. The motors deliver high starting torque (up to 3 times rated torque) with low starting current, ensuring smooth material lifting operations. System efficiency reaches 90-95%, reducing energy consumption by approximately 20% compared to traditional asynchronous motor systems.
Fan Drives For cement plant fans (including ID fans, FD fans, and cooling fans), JASUNG PMSM motors maintain high efficiency across the entire load range (20%-120% of rated load). The power factor remains close to 1.0, eliminating the need for additional power factor correction equipment. Variable speed operation through frequency converters allows precise airflow control, matching production requirements and further reducing energy consumption.
Ball Mill Drives
Ball mills represent one of the most energy-intensive applications in cement production. JASUNG's gearless permanent magnet direct drive motors connect directly to the mill, removing the gearbox and associated maintenance requirements. The direct drive system achieves energy savings of up to 20% while providing high starting torque capabilities. The technology has been validated through extensive testing, with power ranges available from 22kW to 630kW. 8 9 Powder Separator Applications For powder separators in cement grinding circuits, JASUNG PMSM motors offer precise speed control and high efficiency operation. The motors maintain 95-97% efficiency even at partial loads, with power factors above 0.95 throughout the operating range. The compact design and low noise operation make them ideal for integration into existing separator systems.
PMDD Pulley for Conveyor Systems
JASUNG's Permanent Magnet Direct Drive (PMDD) pulley technology revolutionizes belt conveyor systems by integrating the motor directly into the drive pulley. This innovative design eliminates the traditional motor-reducer-pulley transmission chain, resulting in:
• Energy Efficiency: Transmission efficiency increased by 15-20% compared to conventional systems
• Space Savings: Compact design reduces installation footprint by 30-50%
• Reduced Maintenance: No gearbox oil changes, no belt adjustments, minimal lubrication requirements • High Reliability: System failure rate reduced by more than 80% due to simplified mechanical structure
• Low Noise Operation: No mechanical transmission components, reducing noise levels by up to 10 dB
The PMDD pulley system supports belt widths from 500mm to 2400mm, with roller diameters ranging from Φ500mm to Φ1600mm. Power capabilities extend from 22kW to 630kW, accommodating various conveyor configurations in cement plants.
