Powder Concentrator ZKX800 Air Classifier for Cement Grinding Separation Line

The Powder Concentrator ZKX800 is an air classifier that separates ground material into finished fine powder and coarse material for re-grinding. Feed enters a whirling air stream that throws the coarser particles outward to be returned to the mill while the fine product is carried out with the air for collection. Used in closed-circuit grinding systems, it works with a ball or rod mill to raise grinding efficiency, reduce over-grinding and improve the fineness and consistency of the finished product. Its simple, robust construction and straightforward adjustment make it a reliable, low-maintenance addition to cement and building material grinding lines.

• Efficient Air Classification: A rotating air stream cleanly separates fine and coarse particles, delivering a consistent finished product fineness.
• Closed-Circuit Grinding Partner: Returning coarse material to the mill avoids over-grinding and raises the capacity and efficiency of the grinding system.
• High Capacity: A large housing and strong air flow handle high tonnages of cement or stone powder in continuous duty.
• Adjustable Fineness: Air volume and rotating speed can be tuned to control the cut point and match the required product fineness.
• Robust Simple Construction: A sturdy, simply built classifier resists abrasive dust and needs little maintenance, keeping downtime low.
• Durable Wear Parts: Wear-resistant blades, liners and housing protect the machine from the abrasion of continuous powder handling.

Powder concentrators are used in cement plants to classify ground cement and raw meal in closed-circuit grinding lines, and in building material and mineral plants to classify limestone, gypsum, slag and non-metallic mineral powders. They improve grinding efficiency and product fineness wherever fine classification is required.

The concentrator ships with the housing and rotating parts protected and the drive unit crated. A full set of drawings and an operating manual are included, and each unit is inspected before dispatch. We provide a twelve-month warranty and a dependable supply of blades, liners and bearings to keep your classification stage efficient.
