How is the power of the shaftless trommel screen calculated?

Apr 06, 2022

Shaftless trommel screens are widely used in power plants, coking plants, building materials, metallurgy, chemical industry, mining and other industries to overcome the sticking problem of various vibrating screens in the wet material screening process and improve the output and reliability of the screening system. It is suitable for the screening of materials of various properties, as well as wet and easily blocked materials, such as coal, coal gangue, coke slaked lime, the screened product is 100 mm, the middle is 10-50 mm, and the fineness can reach 3 mm or less, and the product is well received. User reviews.


How is the power of the shaftless trommel screen calculated? In fact, the calculation power of the shaftless trommel screen is better, just remember the formula: P=[C* F* L*(3.6 Gm* v+ Qt)+ Qt* H]/36. P=Axial force of drive shaftless trommel screen (Kw), C=resistance coefficient of conveyor belt, bearing, etc., F=resistance coefficient of idler roller, F=0.025-0.030, L=horizontal projection of distance between trommel screen (m ), Gm=weight of rotating parts such as conveyor belt, idler roller, reversing roller, V=belt speed (m/s), Qt=conveying amount (t/h), Qt=conveying amount (t), Gm=conveying Weight of rotating parts such as belts, drums, and drums, V=belt speed (m/s), Qt=conveying capacity (t/h), Qt=conveying capacity (t/h), Qt=conveying capacity (t/ h), Qt=conveying volume (t/h), Qt=lv*density of conveyed material, Gm=weight of rotating parts such as conveyor belt, drum, drum, V=belt speed (m/s), Qt= Conveying volume (t/h), Qt=conveying volume (t/h), Qt=lv*density of conveyed material.


After the shaftless trommel screen runs, the material is discharged slowly or the material is discharged. The first thing to consider is the number of sieve holes, whether the sieve holes are too small to cause clogging.


Sieve and discharge are horizontal or height. (The vibrating screen will not discharge or discharge according to the height of the exhaust port for different materials).


Whether the screen surface and the discharge are in the horizontal position during operation is directly related to the screening effect of the equipment. If they are not in the horizontal direction, they should be adjusted in time. The key is that the vibration motor adjusts the angle of the eccentric block. The smaller the angle, the faster the spread.


The angle of the eccentric block of the vibrating motor should be adjusted to about 5°. As required, the angle of the motor should not be too small, otherwise the material will spread out quickly and affect the shielding effect. Generally speaking, the motor angle of the ex-factory vibrating screen is 45°.
