The summary of application knowledge of dewatering screens
published date: 05-24-2018
Dewatering screen is an exclusive equipment for slime dewatering operations, it is widely used in coal slurry recovery, thickening coarseness of pressure and filtration , and other extremely fine material dehydration, recycling and other technological conditions.
Dewatering screen adopts double electrode self-synchronization technology, universal eccentric block, adjustable amplitude vibrator. It mainly consists of screening box, vibrating motor, supporting system and motor.
Two unconnected vibrators are driven synchronously and reversely by tape couplings. The centrifugal force generated by the two groups of eccentric masses is superimposed along the vibration direction and counterbalanced by centrifugal force to form a single vibrational vibration along the vibration direction. The screen box acts as a reciprocating linear motion.
The application range of dewatering screen:
1.For wet sand making production line and sand washing machine supporting use, it can also be used alone. The gravel is washed by a sand washing machine and subjected to hydraulic grading, desliming and sand recycling through gravel dewatering screen to achieve a reasonable particle size ratio , thus reducing the mud content to below 0.7%.
2.The washing equipment for desludging, desorption and dewatering of coal washing plants and can be used to recover slime with a particle size of less than 9mm. It is an exclusive equipment for the dewatering operation of coal slime and is widely used for slime recovery, thickening coarseness of pressure and filtration and the dehydration and recovery operations of other fine materials.
3.Used for tailings drainage, concentrate dewatering and other operations. And it can use for processing fine-grained minerals for the automatic separation of slag water, tailings dry drain technology, etc., and can also be used together with the cyclone as a tailings dry discharge recycling machine, dehydration efficiency is higher.
4.Screening equipment for environmentally friendly use of waste materials has a large amount of processing and good dewatering effect, and is suitable for dewatering and screening materials with high frequency and high vibration intensity.
Reasons and solutions for the breakage of the vibrating screen
The more likely the linear vibrating screen is to appear in various faults during operation, the cracking of the screen plate and the breakage of the beam after the vibrating screen has been used for a long time, it is necessary to find the "cause" of the problem. During the use of the vibrating screen, the correctness of the operation method and the importance of regular cleaning and maintenance usually avoid the occurrence of the vibration screen failure frequency. Vibrating screens are designed to bring efficient results to the production process. The selection of the material of the vibrating screen itself; the calculation of the vibrating motor; the selection of the screen; whether the structural design of the fuselage conforms to the work on site, can select high-quality screening equipment with high efficiency and precision. So find out the cause…
Linear or circular vibrating screen, what is the difference
Circular vibrating screens and linear vibrating screens are common screening equipment in industrial production. However, their working principle is different from that of suitable materials. When selecting vibrating screens, according to the type of materials to be screened, The particle size is chosen to suit the vibrating screen. If a large volume is required, but a circular vibrating screen is selected, the result will not be as expected. First, the characteristics and working principle of the two screening equipment are analyzed. Linear motion vibrating screen working principle When the linear vibrating screen is working, the trajectory of any point on the screen box is a straight line, that is, when the eccentric block rotates, only one force is generated in a certain direction. Then the vibrating screen only performs a linear motion of the plane reciprocating in this direction. The…
Vibration frequency, screen inclination of the vibrating screen
Vibration characteristics include vibration frequency, amplitude, vibration direction angle, and screen inclination. If these parameters are set incorrectly, it will affect the working efficiency of the vibrating screen. The correct way is: 1. Screen angle α The angle between the screen surface and the horizontal plane is called the screen angle. The size of the dip is closely related to the throughput of the screening equipment and the screening efficiency. When the inclination angle is increased, the throwing strength of the material on the sieve will be increased, so that the forward movement speed of the material on the sieve surface is accelerated, so that the treatment amount of the vibrating screen is increased, but the residence time of the material on the sieve surface is shortened, and the opportunity for screening the sieve is reduced. , thereby reducing the…
Trommel screen maintenance manual
During the use process, the trommel screen runs slowly and evenly, with small impact vibration, stable operation and simple installation. It can be placed directly on a flat floor or floor and under the silo. The machine is easy to close and collect dust, has small maintenance, simple maintenance and long service life. Trommel screens are equipment commonly used in refractory materials, coal, river sand classification, and sand block classification. Do a good job of equipment maintenance to keep the drum screen in a good working condition and delay the service life of the equipment. watch trommel screen working videos Trommel screen maintenance Use the drum screen to do the part of the equipment reducer and support the lubrication of the bearing parts. The grease used in the roller screen bearing part is calcium-based grease, and the lubrication of the…
