Wuyuan zinc-molybdenum ore crushing, ball milling, flotation operation process
Broken part:
The main equipments for the crushing part are two jaw crushers 600x900 and 400x600; one for each of the 1750, 1650 and 900 cone crushers . Among them, the 1650 crusher is a hydraulic control system.
When starting the car
First, start the dust removal equipment to reduce the amount of dust in the air during normal operation.
Secondly, when the crusher is started, the lubrication system of the 900 cone crusher is started to ensure that the bearing of the 900 cone crusher is properly lubricated, and then the 900 cone crusher and the ore belt and the ore belt and the total belt and vibrating screen of the No. 1 silo are started. . Then start the lubrication system of the 1750 cone crusher to ensure that the bearing of the 1750 cone crusher is properly lubricated, and then start the 1750 cone crusher and the ore belt and the ore belt. After confirming that the equipment is operating normally, start the No. 1 400x600 jaw crusher.
Finally, after confirming that the equipment is operating normally, start the 600x900 jaw crusher on the mountain and the feeding belt and vibrating screen of the 400x600 jaw crusher.
The connecting belt between the No. 1 and No. 2 bins is started when the No. 2 bin needs to be fed. Mainly for the No. 3 ball mill feed.
When parking
Contrary to the above starting sequence. First stop the 600x900 jaw crusher on the mountain. When the ore belt of the 1750 crusher is out of material, stop the No. 2 and the cross belt. Then stop the No. 1 400x600 jaw crusher and the No. 2-1 belt, then listen to the 1750 crusher and the 1750 bearing lubrication system and the No. 2-3 belt. The belt and 900 cone crusher and 900 cone crusher bush lubrication system can be stopped only when there is no material in the 900 cone crusher and on each belt. Finally stop the dust removal system.
The 1650 cone crusher and the No. 2 400x600 jaw crusher are used as backup devices to start and stop the same method as above.

Ball milling, flotation part:
The main equipments of the flotation workshop are: BF4 series flotation machine 15 sets, 6A series flotation machines, a total of 27 sets of 16 selected workshops, 11 BF10 series flotation machines, 9 sets of 4A series flotation machines, BF10 mixing, BF4 mixing, BF4 lifting, 6A mixing, coarse and fine mixing, one set of concentrate lifting pump, 2 sets of fine tail pump box lifting pump and 2 sets of coarse and fine foam lifting pump.
When starting the car
Start from the selected workshop 4A series flotation machine No. 5 to order the 6A series flotation machine No. 16 (Note: 4A series flotation machine No. 1 to No. 4 mainly look at the ore grade to decide whether to start). Then start the BF4, BFA10, and 6A series flotation machines in the coarse and fine mixing and roughing workshop, and the 6A, BF4, and BF10 mixing tanks. Finally, the ball mill and the classifier are started, and the vibrating screen and the feeding belt are started when the equipment is operating normally. (Note: When there is foam in the flotation machine, the water pipe and scraper should be opened at the same time when the flotation machine is started)
When parking
First dip the material, and stop feeding the belt. After the ball mill is running for a period of time, stop the ball mill, and the classifier and the ball mill and classifier. Then, look at the coarse slurry inside the flotation machine and the agitation tank, and then confirm the roughing and then stop the rough selection. Finally stop the selection, and drain the mine water.
Note: The above operation procedures are all starting and stopping sequences under normal conditions. In case of sudden power failure or other situations, the power must be disconnected to ensure that all parts of the switching power supply are disconnected to avoid sudden transfer. Unnecessary damage.

Our wood Force Control System, wood active contact flange, wood Constant Force Actuator have many advantages over other grinders. It can realize flexible grinding, quick repsond to surface changing, and instant adjusting. Traditional mechanic hand lacks flexibility, and it is not easy to adjust, hard to realize mass production.
