CLF flotation machine

What is CLF flotation machine?

CLF type flotation machine, also known as CLF type coarse and heavy particle flotation machine, is a kind of full-grain inflatable mechanical agitation flotation machine, capable of separating minerals with regular grain size and coarser grain size, higher density and higher concentration, especially suitable for separating minerals containing coarse grains, such as quartz sand, smelting slag, and so on.

If you are a beginner and do not know about flotation machine, tell us your raw material characteristics, finished product requirements, site conditions, production budget, hourly production, and other requirements, we have professional engineers to equip you with a suitable model at a reasonable price. Next, let’s see the types of flotation machine we can supply.

What Is CLF flotation machine Used For?

CLF type coarse particle flotation machine is mainly used for separating nonferrous and ferrous metals and chemical raw materials, which is suitable for the separation of coarse particle level and also takes into account the separation of fine particle level.

For example, A domestic barite beneficiation plant to provide mining industry-wide industry chain service project, through the test, Chunlei customized the re-election – flotation joint process. Among them, the flotation part adopts CLF-type coarse particle flotation machine, which is mainly characterized by high flotation pulp density and high inclusion concentration, and can effectively improve the recovery rate of coarse and heavy minerals.

Applicable materials: Separation of non-ferrous and ferrous metals and chemical raw materials.

Working Principle of CLF Flotation Machine

The impeller of CLF type flotation machine adopts high specific rotation number backward tilting blade impeller, and the shape of lower blade is designed to be consistent with the flow line of slurry through the impeller blades. Weak stirring force ensures the internal circulation of the slurry along the defined channel at low impeller speed.

The slurry in the upper part flows downward through the circulation channel to the lower part of the false bottom, where it enters the impeller zone under the pressure difference between the aerated and non-aerated zones and the suction force of the impeller. Then through the lattice plate, above the lattice plate to form a suspended layer, coarse-grained minerals can be suspended above the lattice plate, the lattice plate so that coarse-grained minerals mineralization bubbles rise a short distance, so that the coarse-grained minerals in the shallow flotation state, and reduces the turbulence of the slurry in the upper area of the tank, the establishment of a stable separation zone and foam layer.

Advantageous features of CLF Flotation Machine

• It is suitable for the separation of coarse grains and fine grains, and belongs to the full-grain flotation.
• CLF type flotation machine flotation pulp density, high incoming concentration, easy to sink tank, can effectively improve the recovery rate of coarse and heavy minerals.
• It adopts a new impeller-stator system and a tank with a forced circulation channel with false bottom and a checker plate.

Q: What is the CLF flotation machine best suited for?
A: The CLF flotation machine is specifically designed for coarse and heavy mineral particles, such as copper, lead, zinc, and molybdenum. Its unique high-efficiency impeller creates strong slurry circulation, preventing coarse sand from settling.

Q: What is the capacity range of a CLF flotation machine?
A: Single-cell capacity typically ranges from 0.5 to 40 m³. The exact capacity depends on your feed density, particle size, and desired recovery rate. Contact us with your parameters for a custom recommendation.

Q: How much power does a CLF flotation machine consume?
A: Power consumption varies by model and cell size, generally from 2.2 kW to 132 kW per cell. Compared to traditional flotation cells, the CLF series saves about 15-25% energy under the same throughput due to its hydraulic-optimized design.

Q: Does the CLF flotation machine work well for coarse particle recovery?
A: Yes. The CLF machine is engineered for coarse particles (up to 1.0-1.5mm). Its special impeller and stator design produce a lower turbulence but higher slurry carrying capacity, significantly reducing the loss of coarse minerals in tailings.

Q: What is the maintenance interval for the impeller and stator?
A: Under normal operating conditions with moderate abrasive ore, the rubber-covered impeller and stator last 6-12 months. For highly abrasive ores, we recommend our wear-resistant polyurethane or ceramic-lined parts, which can extend life by 2-3 times.

Q: Can I automate the CLF flotation machine?
A: Yes. Each cell can be equipped with an automatic level control system, air flow meter, and froth depth sensor. These connect to your central PLC for full automatic operation, adjusting pulp levels in real time for stable recovery.

Q: Do you provide installation and commissioning support overseas?
A: Absolutely. We send one or two engineers to your site to supervise installation, perform commissioning, and train your operators. Once the flotation circuit runs steadily with target recovery, our team returns.
