2、Overview
     Electromagnetic ore crusher is using electromagnetic vibration principle, direct drive vibration tube high-speed struck crushing material (3000 times / min). High efficiency, small size, light weight, no noise, no dust, etc., is a new and efficient sample preparation tool, and can replace all kinds of sample preparation mill (and all kinds of mortar) rapid preparation of samples.
    Widely applicable in mining, building materials, cement, metallurgy, chemical industry, coal industry, food and other various industry. Especially for coal-fired power plant of fly ash sample preparation is the best.
3、Features
1) Using the principle of electromagnetic attraction, drive tube materials quickly break into a slight state of the system like the new     mill.
2) No transmission parts, with a small, light weight, long life, especially for users less sample preparation.
3) Crush fast, fully enclosed, to eliminate the shortcomings of the dust flying, is the disk, eccentric rotating mill replacement     products
4) For coal, mining, cement, electricity, chemicals, import and export commodities inspection department, quickly smash a variety     of specimens.
4、Packing List
1) Feeding cup 1
2) Wrench 1
3) Fuse 2（10A）
4) O-type ring 2
5) Manual 1
 1) Tube in the feed cup, and a small upside down.
2) Add samples, iron powder, limestone, slag, clinker, comprised, clay 6Og around with the best. Coal to 40g best, small size for around 15-20g.
3) Cover the lid on the material cups, pay attention to the lid of the O-ring is good
4) Will feed cup into host inside lever down again, by hand twist on nut and note nut under should have washers.
5) Tighten the nuts with a wrench, and then close the lid, switch, timer spin to 2 minutes, the machine to work.
6) Scheduled to work until the machine stopped working, then can close the switch, open the lid, loosen the nut, wear gloves to remove the feeding cup, cup after taking out material, the tray into the corner of the lid, so that the sample with into the feed tube with the sample tray.
7) Feed tube with the crucible tongs to grip, another hand with wrench close-hauled feed tube, up, down to shoot a few times, most of the sample that fall into the sample plate.
8) Brush the remaining samples for further brush clearing.
9) If the sample of water or other causes leads to feeding cup inwall adhesion agglomerate,, available to special shovel.
