Manufacturer produces multi slot flotation machines for small-scale mineral processing in university laboratories

Application of XFD type multi slot flotation machine

The XFD multi slot flotation machine is an experimental standard flotation machine used in coal preparation, and is also suitable for industries such as metallurgy, geology, coal, building materials, chemical engineering, and environmental protection. Used for stirring, scrubbing, separating, and selecting small amounts of mineral samples.

The impeller speed, inflation rate, scraper method, and frequency of the XFDM multi tank flotation machine are all adjustable, and the tank volume can be replaced. The constant pressure water replenishment tank can add clean water, and the water level height can be adjusted flexibly and conveniently. If used in conjunction with a digital time program distributor, it can display and control various flotation processes and times, and achieve partial automation of flotation test operations. Therefore, the test accuracy is high and the test results are good, making it an ideal equipment for floatability research and testing.

The XFDII type multi slot flotation machine is an upgraded product of the XFCM type multi slot flotation machine. It adopts frequency conversion technology, stepless speed regulation of the impeller, digital display, and reliable operation. The XFDMII multi cell flotation machine adopts an external inflation device, which is adjustable, accurate and stable.

Manufacturer produces multi slot flotation machines for small-scale mineral processing in university laboratoriesStructure Introduction

The XFD-12 laboratory flotation machine consists of the following main components: lifting mechanism (IV), mechanical continuously variable transmission mechanism (II), head section (I), stator and rotor section (V), and control switch (III).

All components are connected to the column (7). The spindle rotates clockwise, and the motion is transmitted from the motor belt (5) through the V-belt (3) and the spindle pulley (2) to the spindle (1) to drive the impeller to rotate. Loosen the speed control cap (12) and rotate the speed control screw (6) to adjust the impeller speed. The tachometer (9) is connected to the upper end of the spindle with a coupling to measure the impeller speed.

The lifting and lowering of the main shaft impeller is achieved by shaking the handle (10) and pulling out the handle (11). When it reaches the desired position, the handle is placed back and the main shaft is fixed in that position.

The groove is fixed on the square hole of the base (8) by four cylindrical pins at the bottom of the groove.

When the flotation machine is working, with the rotation of the impeller, the slurry in the tank is sucked from the bottom of the impeller to between the blades. At the same time, low-pressure air supplied by the blower enters through the hollow shaft and the air distributor of the impeller. After the slurry and air are fully mixed between the blades, they are pushed out diagonally from the upper half of the impeller, stabilized and directed by the stator, and then enter the entire tank. The bubbles rise to the foam stable zone, and after the enrichment process, the foam flows from the overflow weir and flows into the foam tank. A portion of the slurry flows towards the lower part of the impeller, where it is stirred and re mixed to form mineralized bubbles. The remaining slurry flows to the next tank until it becomes tailings.
