Advantages and Characteristics
Xinhai vibrating screen equipment has a large amplitude and high screening efficiency;
Can provide wear-resistant rubber mesh, with a lifespan 10-20 times that of steel and 4-6 times that of polyurethane;
Can provide high elasticity wear-resistant rubber springs with long service life, low noise, and easy maintenance; Provide two types of vibrating screens: seated and suspended;
There are two forms of vibrating screens: seated and suspended;
The large pulley and eccentric shaft have an eccentricity of 3-5mm, which balances the overall movement of the large pulley during the vibration of the vibrating screen and increases the stability of the transmission;
The material on the self centering vibrating screen can achieve good looseness and stratification under the action of vibration;
The weight of the vibrating screen can be adjusted, and the amplitude of the screen can be adjusted according to production requirements;
When the amount of ore is changed, the amplitude also changes. When the ore supply is low, the amplitude increases and the vibration intensifies, while when the ore supply is high, the amplitude decreases. The change in ore supply will affect the "dynamic balance", resulting in some vibration at the center of the pulley;
Suitable for medium and fine particle screening but not suitable for coarse material screening.
| Working principle | Process diagram of self centering vibrating screen | The principle of self centering vibrating screen is to use the centrifugal inertia force generated when the motor drives the main bearing of the pulley to add to the internal force of the screen box vibration system, driving the center of gravity of the screen box system to make circular motion. The mass of the eccentric weights on the heavy wheels should ensure that the centrifugal inertia force generated by them can balance the centrifugal inertia force generated when the screen box rotates. The condition for preventing displacement of the center of the pulley in space is that the centrifugal inertia generated by the rotation of the sieve box is equal in magnitude and opposite in direction to the centrifugal inertia force generated by the eccentric weight, at which point dynamic equilibrium is achieved. Thus achieving the "self centering" of the pulley, keeping the center distance between the two pulleys constant, eliminating the phenomenon of the belt being loose and tight at times. | Technical Parameter | model | specifications | Upper limit feeding particle size (mm) Processing capacity (t/h) |
