Electromagnetic ore sample mill is the use of electromagnetic vibration principle, direct drive vibration tube high-speed crushing material (3000 times/min) with high efficiency, small size, light weight, no noise, no dust and other advantages, is a new type of sample preparation tool, can replace all kinds of sample mill (and all kinds of mortar) rapid preparation of analysis samples. Widely used in mining, building materials, cement, metallurgy, chemical, coal and grain and other industries of the laboratory. Especially for the thermal power plant fly ash sample preparation is good.
The quantity of the cup can be equipped according to the sample variety of grinding, special sample, the cup does not need to be cleaned after grinding the sample.
Working principle and functional characteristics of electromagnetic ore sample mill
1, using the principle of electromagnetic suction, drive the material tube quickly break the material into a fine state of the new sample mill.
2, no transmission parts, with small size, light weight, long service life, especially suitable for small sample production users.
3, the grinding speed is fast, completely closed, to eliminate the shortcomings of dust flying, is the disc, eccentric rotation mill replacement products
4, suitable for coal, mining, cement, electric power, chemical, import and export commodity inspection departments, quickly crush various samples.
Electromagnetic ore sample mill operation process
l, put the tube into the cup, and put the small end down.
2, put the sample, iron powder, limestone, slag, clinker, quartz stone, clay to about 60g. The best coal is about 40g, and the small size is 15 ~ 20g.
3, cover the cup cover on the cup, pay attention to the cup cover on the O-ring seal is good.
4, put the cup into the main machine and then put down the pressure rod, screw on the nut by hand, and pay attention to the washer under the nut.
5. Tighten the nut with the hand, close the lid, open the switch, turn the timer to 2 minutes, and the machine starts to work.
6, the machine work to the predetermined time to stop working, then you can turn off the switch, open the box cover, loosen the nut, with gloves to take out the cup, after the cup is removed, put the cup cover into the corner of the sample tray, so that the sample and the material tube together into the sample tray.
7. Clamp the material tube with the crucible pliers, slap the material tube with the plate hand with the other hand, and pat the material tube up and down several times, and most of the samples fall into the sample tray.
8. Further brush the residual sample with a brush.
9. If the inner wall of the material cup adheres to clumps due to large sample moisture or other reasons, it can be removed with a shovel.
Electromagnetic ore sample mill precautions
1, the voltage should meet the requirements, the voltage is too low will make the relay suction is not good, and burn out, should immediately turn off the power
2, the ground wire must be good.
3, the sample moisture is too large should be dried before grinding.
4, the material cup cleaning: if the material cup is specified according to the variety, it can be cleaned or simply cleaned, and the user can purchase more material cups according to the need.
5, the material cup of this machine generally do not wash with water, if washed with clean water, after washing should be immediately put into the oven to dry, so as not to rust.
6, some users are used to using the sample grinding method to clean the cup tube, the sample to be ground first take out a part of the grinding dump, and then formally sample into the grinding. Or pre-grinding with quartz sand or slag to clean the crushing device, these methods may be necessary in particularly strict test occasions, but the pre-grinding material can not be too much too little, and 10 seconds to 30 seconds is enough.
