Operation and usage methods of DF-4 electromagnetic sample pulverizer
Place the material tube into the material cup with the small end facing downwards
Put in the sample, with iron ore, limestone, slag, clinker, quartz stone, and clay weighing around 60g. Coal should be around 40g, with a small specification of 15-20g.
Place the cup cover on the material cup, paying attention to whether the O-ring seal on the cup cover is in good condition
Place the material cup into the main machine, then lower the pressure rod, screw on the nut by hand, and note that there should be a gasket under the nut
Use a wrench to tighten the nut, then close the box cover, open the switch, and turn the timer to 2 minutes before the machine starts working
The machine stops working at the predetermined time. At this point, the switch can be turned off, the box cover can be opened, the nut can be loosened, and gloves can be worn to remove the material cup. After the material cup is removed, the cup cover can be placed in one corner of the sample tray, so that the sample and the material tube can be poured into the sample tray together
Clamp the material tube with a crucible clamp, and tap the tube with the other hand using a wrench. Repeat the steps up and down several times, and the vast majority of the samples will fall into the sample tray
Use a brush to further brush away the remaining sample
If the inner wall of the material cup adheres and agglomerates due to high sample moisture or other reasons, a shovel can be used to remove it
