The following is a brief introduction of the representative equipment-the structure, principle and operation rules of the dredging iron dressing ship:
The sand dredging iron ship consists of a floating body, a chain bucket sand dredging system, a screening system, a magnetic separation system, a tail sand removal system, and a power system.
First of all, there is water in the river. Our beneficiation equipment must work on the surface of the water, so we use 3.5-4 mm steel plates to make the floating body. According to the depth of the dredging, the width and length of the floating body have corresponding dimensions. Requirements: Generally, the width is between 1.5-2 meters and the length is between 16-32 meters.
In addition, in order to increase the stability of the ship, there is a certain distance between the two floating bodies, which is generally about 1.5 meters. As the name suggests, the loading system of this beneficiation equipment is a chain bucket type sand dredging system. After the river sand is brought up by the chain bucket, because there are stones of different sizes, in order to protect the safety of the magnetic separator, it must pass through a screening system.
Depending on the environment of the river, in general, the river with fewer stones and smaller diameters is better with a self-vibrating type, which is easy to maintain and saves power (about 3KW). And the river with a lot of stones and a relatively large diameter will use a roller sieve. The sieved stones generally flow directly into the river. If there is economic value, they can be transported to the shore for sale; the river sand is transferred to the magnetic separation system. The magnetic separation system is mainly a magnetic separator and a washing selection system.
The magnetic meter strength of the magnetic separator must generally reach 3800-4500 Gauss, and the specifications are 750 * 2200-2400, so that the matching can achieve a net selection rate of 90%. The effect of water washing is to improve the grade of wrought iron powder. Generally, it can be freely adjusted between 30-45. The function of the tailings removal system is to discharge the tailings of iron powder away from the machine to ensure that the machine can work normally. Generally, there are three types of self-flow type, conveyor belt type and sand pump type. Of course, this is also determined according to the specific environment of the river.
