How to safely maintain the laboratory small DF-4 electromagnetic ore crusher

Electromagnetic ore crusher, also known as electromagnetic ore crusher, uses the principle of electromagnetic vibration to directly drive the vibrating tube to hit the crushed material at high speed (3000 times/min) with high efficiency, small volume, light weight, no noise, no dust, etc. It is a new type of high-efficiency sample preparation tool. It can replace all kinds of sample pulverizers (and various kinds of mortars) to quickly prepare and analyze samples. It is widely used in mining, building materials, cement, metallurgy, chemical, coal and other industries. Laboratory. Especially for the preparation of fly ash samples from thermal power plants.

The instrument is used by cement, mining, oleochemical and other units, and the trial of the National Cement Quality Supervision and Inspection Center, which proves that the performance is excellent. It is an ideal sample pulverizer. It is supervised by the National Cement Quality Supervision and Inspection Center and promoted nationwide. application.

DF-4 electromagnetic ore crusher technical parameters

l, the power supply voltage is 22O volts ± 10 volts, the current is 6A.

2, the feed size ≤ l5 mm, the discharge size ~ 2OO mesh, but the sieve can be chemical analysis.

3. The quantity of each sample is divided into general type and special type. The general type is about 50 grams according to the national standard. The actual sample can be loaded with 40 to 80 grams, 6og is good, and DF-4 is universal. The second loading is 0~2Og.

4, the pulverization time, O ~ 5 minutes adjustable, generally not more than 2 minutes.

5, weight l8 kg, volume 22 × 25 × 25 cm, (DF-3 type, weight 7 kg, volume 18 × 18 × l6 cm).

6. The number of cups can be equipped according to the type of smashed sample. It is special for special samples. After grinding the sample, the cup does not need to be cleaned.

DF-4 electromagnetic ore crusher features

1. Using the principle of electromagnetic attraction, the material tube is driven to break the material into a fine sample state.

2, no transmission parts, small size, light weight, long service life, especially suitable for users with less sample preparation.

3, the smashing speed is fast, fully enclosed, to eliminate the shortcomings of dust flying, is the replacement product of disc and eccentric rotary pulverizer

4. It is applicable to coal, mining, cement, electric power, chemical, import and export commodity inspection departments, and quickly smash various samples.

DF-4 electromagnetic ore crusher operation process

l. Place the material tube into the material cup with the small one facing down.

2, put the sample, iron dress, limestone, slag, clinker, quartz stone, clay about 6Og or so good. The coal is about 40g, and the small size is 15-20g.

3. Cover the cup on the cup and notice that the O-ring on the cup is good.

4. Place the cup into the main unit and lower the pressure rod. Screw the nut by hand and pay attention to the gasket under the nut.

5. Tighten the nut with the wrench, then close the lid, open the switch, the timer is turned to 2 minutes, and the machine starts working.

6. The machine stops working after the scheduled time. At this time, the switch can be closed, the lid can be opened, the nut can be loosened, and the glove can be taken out with the glove. After the cup is taken out, put the lid into the corner of the sample tray to make the test. Pour the sample into the sample tray together with the tube.

7. Clamp the tube with a simmering pliers. The other hand pats the tube with a wrench, and shoots it back and forth several times. Most of the sample falls into the sample tray.

8. Brush the remaining sample with a brush.

9. If the inner wall of the cup adheres to the agglomeration due to large moisture or other reasons, use a special shovel.

DF-4 electromagnetic ore crusher precautions

1. The voltage should meet the requirements. If the voltage is too low, the relay will not be properly sucked, and if it burns out, the power should be turned off immediately. Long time below 210 volts. A regulator can be purchased separately from the factory.

2, the ground wire must be good.

3. If the sample moisture is too large, it should be dried before being put into the mill.

4. Cup cleaning: If the special cup is specified according to the variety, it is not necessary to clean or simply clean it. Users can purchase the cup as needed.

5, the machine cup is generally not washed with water, if rinsed with water, should be placed in the oven immediately after washing to avoid rust.

6. Some users are accustomed to cleaning the material cup tube by the method of over-grinding the sample. The sample to be ground is first taken out and grounded, and then officially sampled into the grinding. Or pre-grind with quartz sand or slag to clean the pulverizing device. These methods may be necessary in particularly rigorous testing situations, but the pre-ground material should not be too much and too little, and it takes 10 seconds to 30 seconds. enough.
