Flotation machine operating procedures


Items to check before operation
First, to prevent debris into the flotation tank, in order to avoid jammed impeller, clogging false bottom circulation holes and channels affect pulp cycle and, if necessary, should play an open mine gate rinse tank to eliminate debris.
Second, check valve ore, hold switch and flexible. Production of other requirements depending on the options, the adjustment of discharge, to maintain a desired level height pulp.
Third, all of flotation machine and blade drive V-belt must be secured neatly smooth, elastic consistency.
Fourth, the cabinet must be smooth rubber lined neatly, false bottom and steady flow plates, baffle must be complete, set stable.
Fifth, check the air line is smooth, if unimpeded should be clear immediately.
Six, check liquid level control system is flexible and reliable.
Seven, if filled with grease spot inspection of each oiler mixing bucket, the proper amount of grease to the bearing Check all loose fasteners.
Eight, hand plate moving mixing bucket pulley device to observe the vertical axis rotation is flexible impeller is collision, friction deflector phenomenon.

From the car order
First, the empty slot start
First to the mine, started mixing drum, start-up and connected to the mining midge box flotation machine, start the DC groove adjacent pulp flotation machine until completely submerged cover.
Second, after the shutdown started full tank
At full tank starts, follow the pulp flow direction, until the next station after starting the process equipment in order to open mixing drum, the first drive, and then open the ore slurry flows into the tube so that the slot until the flooding so far, but not the pulp from the mixing drum along spills, and then put into a predetermined chemical, resume normal stirring operation. Successive start from the last tank to the first slot.
Boot sequence: 1) Make sure the air intake pipe tune lid open. 2) Start the flotation machine motor. 3) Start stir
Mix barrel. 4) began to mine.
Third, according to the process from the car
Open roughing, fine , fine flotation machine, flotation open sub-ore slurry tank.

Parking order
First, the flotation machine downtime order emptying pulp
1, stop to mine.
2, to the mine after a complete stop, open the rear gate. 3, stop mixing drum 4, the normal operation of the flotation machine.

5, you can see the cover, turn off the flotation machine motor. 6, play an open valve to drain away the ore slurry tank surplus.
