Permanent Magnet Direct Drive System for Rocking Bed
·The shaking table permanent magnet direct drive system is suitable for various operations including roughing, concentrating, and scavenging, enabling the sequential production of final concentrate and final tailings. It separates coarse sand (2-0.5mm), fine sand (0.5-0.074mm), and mineral mud (-0.074mm) across different particle sizes. Widely employed for separating tungsten, tin, molybdenum, rhenium, iron, vanadium, chromium, titanium, manganese, lead, rhenium, gold, coal, and other rare metals and precious metals. When processing tungsten or tin ores, the shaking table's effective recovery range spans 0.022-2 millimetres.

Permanent Magnet Direct Drive System for Belt Conveyors
·Traditional belt conveyors employ Y-series motors coupled with gearboxes to drive the conveying mechanism, resulting in low efficiency and high maintenance costs for the gearboxes. · The permanent magnet direct-drive system for belt conveyors employs a permanent magnet synchronous motor coupled with a variable frequency drive for direct drive. · The motor features an external rotor design, integrated with the drum in a unified construction. The drum surface functions as the motor's rotor, while the drum shaft remains stationary, acting as the stator. ·Thus, the motor is the drum and the drum is the motor, enabling more direct transmission and a more compact structure.

Permanent magnet direct drive system for agitators
The permanent magnet direct drive system for flotation machines employs a permanent magnet motor for direct drive, replacing the conventional asynchronous motor plus pulley drive configuration used in traditional flotation machines. The permanent magnet motor is vertically mounted, with its output shaft directly coupled to the agitator spindle, and features variable frequency starting. The system boasts a simple structure, strong load starting capability, high efficiency, low failure rate, and reduces equipment operating and maintenance costs.

Mill Permanent Magnet Drive System
·Existing mining mills employ AC induction motor drive + hydraulic/ air coupling connection + gearbox reduction + large-small gear reduction transmission + drum output structure, or electromagnetically excited synchronous motor drive + air coupling connection + large-small gear transmission + drum output structure. ·This configuration suffers from a lengthy mechanical transmission chain, low efficiency, complex mechanisms, and requires substantial daily maintenance through slow transmission systems and lubrication systems, resulting in significant operational maintenance workload. ·The permanent magnet motor system for mining mills employs an integrated design of motor and mechanical structure, eliminating intermediate power transmission stages. This removes traditional mill components such as reduction gearboxes, couplers, and slow transmission systems. Utilising a permanent magnet direct-drive motor, the mill directly meets load requirements, resulting in a simplified system architecture.
