Hematite is an important mineral resource for obtaining iron. Hematite concentrate is obtained through mineral processing, and then iron substances or steel materials are obtained through smelting. Flotation is a commonly used method for selecting hematite. It mainly uses flotation and equipment to complete flotation. Common hematite flotation machines and equipment include: KYF type, XCF type, JJF type, SF type and BF type. Several types. Let’s take a look at the differences between these types of equipment. How to choose?

1. The difference between mechanical agitation and air-filled agitation flotation machines

The mechanical agitation flotation machine is an air-generated flotation machine. The suction flotation machine mainly relies on a mechanical agitator (rotator and stator) to realize the aeration and mixing of the slurry. It can self-prime air and self-prime slurry without the need for external aeration devices. The return of the middle ore does not require pump transmission.

The inflatable agitator flotation machine is an external air supply flotation machine, which mainly relies on a mechanical mixer to stir the slurry and a blower to aerate. This type of flotation machine cannot self-aspirate. When the middle ore returns, a lift pump is required to transport the slurry. In addition, special air supply equipment needs to be configured.

2. Differences between various types of flotation machines

KYF flotation machine

This flotation machine is a type of inflatable flotation machine. The structure is U-shaped, and its main feature is that the impeller structure adopts a new cone design with backward-inclined blades, similar to the impeller of a centrifugal pump. This design can increase the slurry processing capacity of the flotation machine and reduce energy consumption. In addition, it is also equipped with an air distributor so that the air can be evenly dispersed around the impeller to expand the contact area between the slurry and the air.

XCF type flotation machine

This flotation machine is similar to the KYF type. The main difference is the impeller. This machine has a stator added to the impeller to form a negative pressure area, so it can Self-priming slurry. Since KYF cannot self-prime slurry, it is usually combined with XCF to form a combined unit. XCF is used as a slurry suction tank and KYF is used as a direct flow tank.

JJF type flotation machine

This type of flotation machine has a simple structure, a shallow flotation tank, a small impeller diameter, an umbrella-shaped stator design, and a dispersion device (dispersion cover). ), can separate the slurry from the foam layer while keeping the foam layer stable.

There are two types of flotation machines, namely jjf flotation machine and JJFⅡ flotation machine, among which jjfⅡ There are many specifications of flotation machines, and they can be combined with jjf type flotation machines to form a combined unit in the mineral processing plant.

SF type flotation machine

This flotation machine can self-prime air or self-priming slurry. The tank adopts a forward-inclined design and is equipped with a prosthetic device inside. The slurry forms an upper and lower double circulation, and the slurry circulation ability is strong, which is conducive to the floating of coarse-grained minerals and improves the mineral separation effect.

SF type flotation machine can be used alone, or can be used as a slurry suction tank and JJF type flotation machine. Combined unit use.

BF type flotation machine

This flotation machine is an improved equipment based on the SF type. The impeller adopts a double conical disc design, which effectively enhances the lower circulation capacity. BF flotation Since the machine itself can absorb slurry and air, when configuring the flotation machine, multiple flotation machines can be configured horizontally. The mine does not need to be transported by a pump, which not only reduces the investment in the pump, but also reduces the investment in height difference infrastructure.

The above is an introduction to the types and characteristics of several flotation machines commonly used in hematite concentrators. As for which one to choose, it needs to be determined according to the properties of hematite ore and flotation requirements, and cannot be blind. Choose equipment to avoid economic losses.
