scraper conveyors have gained a huge spread in the coal industry.They can move goods in a stationary trough using a scraper, which connect mobile chain.These conveyors are used to transport powdered, granular and lumpy cargo.
Types of conveyors
are two types of conveyors that are different from one another embodiment of the principle of movement and cargo.
1 type - conveyors with very high scrapers;
type 2 - conveyors with submerged scrapers (cargo moving solid mass).
Scraper conveyor used to transport goods which are not subject to breakage, that is, the quality is not reduced for this reason.With these conveyors can be moved with a small load resistance pieces as if they are solid, the wedge can start hitting between the gutter and the scraper.
scraper conveyor with large scrapers
gutter scraper conveyor with large scrapers are made of steel with a thickness of 3-8 mm.To increase the service period of the scraper conveyor, scraping the bottom edge of one strip of solder material is resistant to wear (they can be a high-manganese steel).Also, apply plastic scrapers.The length of the individual elements is determined depending on the angle of repose, the chain pitch, the size of pieces of cargo, as well as height.The length of the pig, which we have chosen to be the best way to ensure filling of the space between multiple step chains and scrapers.But remember that the length should be slightly larger than the largest size of a piece.Form gutters can be very different.
scraper conveyor with scrapers must be shipped at the same performance is much less mass and dimensions than the conveyor with large scrapers.These conveyors have a trough of two parts: one for - single, the second - to work branch.Loads must fill completely the whole of the gutter.Thus, when moving the load circuit moves along the chute.
conveyor with scrapers immersed able to move goods in vertical, horizontal and even sections of the route.Therefore, they are designed to move small-sized, granular, dust and free-flowing goods.Drag Conveyors with ease and without overloading can lift a load to a height of 20 meters, move it to a distance of 100 meters, to increase the capacity up to 700 t / h.
Benefits conveyors
Among the advantages of particular importance can be given to the excellent filling section of the trough and movement of goods, without overloading the rather challenging tracks and turns.
Disadvantages conveyors
drawbacks scraper conveyor is less than the benefits, but, nevertheless, they are.In intensive wear trough conveyors and scrapers, and they spend a lot of energy.More attention should be paid to the fact that this device is difficult to convey the sticky, wet and abrasive loads, as they tend to be between the troughs and scrapers.
Now you know that such a scraper conveyor!
