1, the structure of the solid. Can withstand rushed to coal, coal gangue, or other materials, hit, hit a external force, pressure, etc.

2, can meet the needs of the mining face slab uneven, bending over, can withstand the vertical or horizontal bending.

3, the fuselage short, easy to install.

4, can double as coal winning chance the orbit.

5, can reverse running, easy to handle bottom chain accident.

6, the front of the hydraulic support can the fulcrum.

7, simple structure, the transmission length can be arbitrary point on feeding or discharging.

8, casing airtight, when conveying material can prevent the dust float in the sky and pollute the environment.

9, when its tail is not to set casing, and insert the scraper windrow, can take the material transporting.

Disadvantages:

1, no-load power consumption greatly, for about 30% of the total power.

2, shoulds not be long distance transportation.

3, easy happening off chain, chain accident.

4, steel consumption. The cost is big.

Classification of coal industry standard MT/T105-95 fold "scraper conveyor general technical conditions" regulation:

Form a complete set of scraper conveyor motor power under 75 kw for light

75 ~ 110 kw for medium

132 ~ 200 kw is heavy

More than 200 kw for super-heavy scraper conveyor.

The scraper conveyer operation procedures Folding 1, attire, the valid certification.

2, earnestly implementing coal preparation plant safety rules, known as the, number of come off sentry duty, on duty and the order of start, stop, technological process and equipment of, clear set of control signals.

3, must carefully check the mechanical equipment and parts before driving screw is normal.

4, check the process, personnel should be on the safe position, it is forbidden to all parts of the body into the scraper and the casing.

5, in operation to check operation of the chain plate, chain firmness, chain and head gear is normal.

6, clear in the first round of debris or in the store must be a power outage. zmjt07

7, such as found off the chain or goods more pressure, should immediately stop, processing personnel stood on both sides of the body, it is forbidden to deal with faults in the operation.
