High-Efficiency Flotation Machine for Mineral Processing

Flotation machine is a novelly structured self-priming flotation machine.It has advantages of horizontal configuration,midding foam self-returning, air self-priming,etc. Besides, It also has advantage of low consumption, large inflow velocity, strong ability of inhaling pulp, low speed of impeller line, large gap between impeller and plate, tiny abrasion, long using cyclicality of wear-out parts compared with other flotation machines. The consumption is lower, inflow velocity is larger and the surface of ore solution is more steady than flotation machines. flotation machines are widely used for roughing, selecting and anti-flotating the non-ferrous metals,ferrous metals and non-metallic minerals such as copper, aluminum, zinc, nickel, molybdenum, gold, silver, sulphur, phosphorus,etc.

Maintenance & Lubrication Guidelines for Flotation Equipment 

Proper lubrication is essential to extend the lifespan of your industrial flotation machine and ensure smooth operation.

Main Bearing Lubrication: The main bearing requires calcium-based grease. Lubricant should be added twice per shift to maintain optimal bearing performance.

Gearbox (Reducer) Lubrication: The speed reducer utilizes 45# gear oil for bath lubrication. A complete oil change must be performed every six months.

How Does the Froth Flotation Equipment Work?

When the spindle rotates through motor drives impeller, the mine slurry in the impeller cavity throws around under the centrifugal force,which make negative pressure in the impeller cavity. Air is inhaled via admission pipe, meanwhile,the mine slurry under the impeller is inhaled through the center hole that in impeller cone, and mixed with air in impeller cavity, after that, the mine slurry is throwed around via the passage between the flat and the blade. 

The air and some of mine slurry move upper the flotation cell involved in flotating processing after throwed away from the passage between flat and blade.Besides, the other mine slurry moves at the bottom of flotation cell forming under circulating of mine slurry via suction from impeller and flow into impeller cavity for the second time.The existence of under circulating of mine slurry is good for flotating coarse particles of mineral and maximum reduce arenes settling at the bottom of flotation cell.

Precise installation ensures the high sorting efficiency of the mineral flotation separator. Please follow these setup standards: 1.Spindle Verticality: After installing the impeller structure, verify that the main spindle is perfectly vertical. 2.Clearance & Gaps: During assembly, ensure the axial gap between the impeller and the cover plate is maintained at 3–5 mm, with a radial clearance of 11 mm. 3.Horizontal Alignment: The overflow weir board and drive shaft must remain strictly horizontal and concentric, ensuring the regulating gate operates flexibly. 4.Cell Sealing: Ensure zero leakage at the bolted joints between individual flotation cells. Secure welding can be applied upon mutual agreement. 5.Commissioning: A test run is required post-installation to monitor bearing temperature and overall mechanical operational stability. 6.Water Test Run: Once the full froth flotation equipment set is installed, a standard dry run must be conducted first, followed by a continuous 8-hour wet test with the cells filled with water before entering full production.

Before starting the ore flotation machine, complete the following safety and operational checks: 1. Fasteners & Impeller: Inspect all structural bolts and ensure the impeller is securely tightened. 2. Belts & Flexibility: Check the V-belts and verify that the impeller rotates smoothly and flexibly. 3. Lubrication Systems: Verify all lubrication points are well-serviced and inspect the unit for any potential oil leaks. 4. Slurry Circulation: Inspect the internal channels to ensure unobstructed pulp and slurry circulation. 5. Adjustment Devices: Ensure the level adjusters and froth discharge mechanisms are flexible and stable. 6. Electrical & Motor: Confirm that the motor and electrical control facilities function reliably. 7. Safety Guards: Verify that all external rotating components are equipped with secure, steady protective shields.

It depends on your daily processing capacity (TPD), ore density, and flotation time required. Zhongxin engineers will design the exact layout based on your ore test report.

The impeller and the stator are the primary wear parts. We use high-wear-resistant rubber or polyurethane to double their lifespan compared to standard cast iron.

Flotation efficiency depends on several key variables: the particle size of the milled ore, pulp density (usually maintained between 25% to 35%), reagent dosage, pH value, and air flow rate. Zhongxin's froth flotation equipment features adjustable air valves and level regulators, allowing operators to easily fine-tune these parameters for maximum mineral recovery.

Yes, absolutely. For corrosive environments—such as copper or gold flotation using acidic reagents—we offer custom flotation separators equipped with stainless steel tanks, anti-corrosive linings, and high-performance polyurethane impellers to ensure long-term durability and lower maintenance costs.

Sedimentation is a common issue that causes premature wear. Our mineral flotation machine solves this through an optimized bottom structure and a high-efficiency impeller design. This combination generates a powerful, continuous bottom slurry circulation that keeps coarse and heavy minerals suspended uniformly within the cell.
