Gypsum Powder Production Equipment
Introduction
Gypsum powder serves as the backbone of many construction materials, from plasters to specialty cements. Hengshui Decheng Machinery & Equipment Co., Ltd offers a suite of gypsum powder production equipment engineered for reliability, ease of maintenance, and consistent output.
Raw Material Handling
Efficient production begins with proper handling of raw gypsum. Our equipment includes heavy‑duty crushers that reduce large gypsum blocks to manageable fragments, followed by belt conveyors with adjustable speeds. Each conveyor is fitted with metal detectors and magnets to protect downstream mills from foreign objects.
Grinding System
The heart of any powder plant is the grinding mill. Hengshui Decheng’s range includes Raymond mills, vertical mills, and ball mills. Each is designed for low vibration, minimal wear, and easy replacement of liners and rollers. Our mills incorporate advanced classifier systems to ensure tight control of particle size distribution, typically in the 20–60 µm range.
Calcination and Drying
Following grinding, gypsum must be calcined to remove crystalline water. Our rotary kilns and flash calciners maintain precise temperature zones (usually 140–180 °C) to produce hemihydrate gypsum with predictable setting times. Integrated cyclones and bag filters capture dust, while waste heat recovery units preheat incoming air, reducing energy use by up to 15%.
Cooling and Storage
Hot, calcined powder exits the kiln into a two‑stage cooler, where ambient air and forced ventilation bring the material to under 50 °C. Coolers are equipped with anti‑blocking agitators. Finished powder is pneumatically conveyed into storage silos, each fitted with level sensors and aeration pads to ensure constant flow.
Automation and Control
A centralized PLC/SCADA system monitors feed rates, mill load, kiln temperature, and dust collector performance. Operators view real‑time dashboards and can adjust key parameters via an HMI touchscreen. Alarm thresholds safeguard against blockages, overtemperature, or unusual vibration.
Conclusion
By integrating robust crushing, grinding, calcining, cooling, and control technologies, Hengshui Decheng’s gypsum powder production equipment delivers high uptime, precise quality, and lower operating costs—ideal for enterprises seeking a dependable production platform.
