Sand choose pontoon is working in the river water, a special equipment of sand inside the iron is separated from the. Usually by way of mining, the river sand to choose pontoon into chain on the grounds and digging hopper chain bucket sand dredging choose pontoon and by sand and sand pumping leading composition sand pumping choose pontoon.

Working principle

First, the river water, our machinery must to float on the surface of the water work, so we 3.5-4 mm steel plate made of floating bodies, according to dredging depth, width and length of the floating body are corresponding size requirements, general width between 1.5-2 meters, the length of 16-32 meters in between. In addition, in order to increase the stability of the ship, the interval between the two floating bodies of a certain distance, generally about 1.5 meters. Just as its name implies, this machine feeding system is a chain bucket type sand dredging system, according to the experience of years of promoting the use of mechanical, this system is the mechanical wear of the fastest, maintenance cost highest part. Therefore, in technological innovation, promote the use of double chain and thicken fights, although the cost is increased a little, but the service life of the system increased three times more than by our customers the consistent high praise. River sand from the chain after the lift up, because there are different sizes of stones, in order to protect the safety of magnetic separation machine, you must go through the screening system. According to the environment of the river, we have designed the self vibration type and the roller type two kinds of different screening forms. Generally speaking, the stone is relatively small, relatively small diameter of the river with the self shock type is relatively good, convenient maintenance, save power (about 3KW). While many stones, and relatively large diameter of the river must use roller sieve. After screening the gravel in general directly into the river, if there is economic value can also be transported to shore on the transfer belt to sell; river sand into the magnetic separation system. Magnetic separation system is mainly magnetic separator and washing selection system. Magnetic intensity of magnetic separation machine in general to reach 3800-4500 Gauss, specifications for the 750*2200-2400, so that matching can achieve a net rate of 90%. The role of water washing is to improve the grade of the iron powder, the general can be freely adjusted between 30-45. The role of the tail sand elimination system is to select the tail sand of the iron powder to be far away from the machine, so as to ensure the normal work of the machine. Generally have self flow, belt type, pumping sand pump in three forms of course, this is also based on the specific environment of the river. The power of this set of machinery is generally the motor, the erection of electric power is difficult to match the river 50-75KW.
