Buried scraper conveyor works

    Buried scraper conveyor transported in the horizontal plane , the material will be scraper chain in the direction of movement of the pressure and the materials own weight ,

and in the internal friction is generated between materials . The friction between the material layer also ensures a stable state, and sufficient

Material in the tank to overcome the movement of the outer friction generated , so that the entire material to form a continuous stream and is transported .
When buried portable conveyor in vertical lift , the material on the direction of movement by the scraper chain pressure , the material will produce the transverse direction

lateral pressure , thus forming internal friction of materials . At the same time as the horizontal section under continuous feed , lower material will have on

Upper material generates tractive force . This tractive force sufficient to overcome the friction and the material in the slot machine outside the friction generated by moving

its own weight and material , the material to form a continuous whole of the material stream is thus improved.
    Enclosure in a closed chain by moving the friction of the blade and the coal coal output continuously at run time the spiral conveyor coal buried in the solid-phase

connected to the traction chain scraper conveyor chute in a closed bulk material conveyor. Such a drag chain conveyor and the blade are buried on

Into the material , the blade section only accounts for part of the trough , the trough accounted for the majority of the material section . It horizontal, inclined or vertical

transportation of materials . Horizontal transport when the blade is flat strip used , the use of bulk materials buried scraper chain and bulk material layer on a cutting force

is greater than the groove wall

The principle of the bulk resistance , resulting in bulk with the blade moves forward , this time the movement of the material layer height and width ratio of the ratio in a

certain range, the material flow is stable.
