The rotor of a LMFTM Flotation Machine is typically a cylindrical or conical-shaped structure made of steel or other durable materials. It is securely mounted on a shaft, which is driven by a motor or another power source. The rotor incorporates one or more impellers, which are blades or vanes attached to the rotor body. The impellers are strategically designed to create turbulence and agitation in the flotation cell, promoting the dispersion of air bubbles and ensuring thorough mixing of the pulp and reagents.
The rotor includes mechanisms for air intake, allowing the introduction of air or gas into the flotation cell. This can be achieved through axial or radial openings in the rotor or through separate air supply pipes connected to the rotor. The air intake is crucial for generating the air bubbles required for the flotation process. As the rotor rotates, the impellers create a turbulent flow in the flotation cell, shearing the air or gas into small bubbles. The rotating impellers also help disperse the bubbles throughout the pulp, maximizing the contact between the bubbles and the mineral particles.
The design of the rotor may include adjustable parameters to optimize its performance. This can include varying the speed of rotation, adjusting the blade angle or pitch, or modifying the impeller size and shape. Adjusting these parameters allows for fine-tuning the flotation process based on specific ore characteristics and desired flotation outcomes.
