XFD 0.5L Laboratory Single Cell Flotation Machine for Mineral Testing

The XFD 0.5L Laboratory Single Cell Flotation Machine is specifically designed for geological, metallurgical, building materials, chemical mining, and research institutions. It is used for stirring, washing, separating, and concentrating small quantities of ore samples. The machine features frequency conversion technology with digital display and stepless impeller speed adjustment, along with external air supply capability for precise regulation and stable performance.

• Frequency converter enables stepless impeller speed adjustment from 0 to 2600 RPM
• Digital display provides clear and stable speed indication
• External air supply generates fine bubbles; self-absorption via negative pressure when external pump is closed
• Improved scraper device and clamping mechanism with wider scraper speed range
• Rear handle locking mechanism facilitates easy installation and removal of the cell
• Optional heater and temperature controller for monitoring slurry temperature
• Optional automatic liquid level replenishment device and automatic reagent feeder for higher automation

The flotation machine consists of the main body, flotation cell, spindle drive components, locking mechanism, external aeration components, scraper, and electrical control components. The stator and rotor rotate at high speed, creating centrifugal force that throws liquid from the rotor center, forming negative pressure. An external air pump supplies air to the flotation cell to generate fine mineralized bubbles. Alternatively, when the external air pump is closed, the machine utilizes negative pressure for self-absorption. Rotor speed is steplessly adjusted via the frequency converter. The flotation cell is secured by the rear handle: clockwise rotation locks the cell, counterclockwise rotation releases it.

Support the cell bottom with your palm, insert it into the clamp, then rotate the locking handle clockwise. Connect to 220V power supply, press the main power switch, use the speed adjustment button to regulate spindle speed (6 RPM adjustment per press), then start the spindle. Start the scraper motor and adjust its speed, then start the air pump and use the flow meter knob to adjust aeration volume. When the impeller wears out, use a screwdriver to fix the spindle or motor fan blades, then rotate the impeller counterclockwise to remove it.

• Machine housing must be reliably grounded
• Never operate the spindle when the flotation cell contains no water
• When moving, apply force to the machine body and base only, never to the working unit, scraper motor, or handle
• Check all fasteners before startup as they may loosen during transportation
• Handle the plexiglass cell carefully to avoid breakage
• Inverter parameters are preset at factory - do not adjust

In addition to daily cleaning and keeping screws tightened, bearings should be lubricated and maintained every six months to one year based on usage time.
