TSX has been committed to the manufacturing and research of the vibrating screen industry for many years. Recently, customers often call to inquire about the operating speed of the vibrating screen and the maximum material handling capacity
- Calculation method of handling capacity:
Q = 3600*b*v*h* γ
Where, Q: treatment capacity, unit: t/h
b: Screen width I unit m
h: Average thickness of material I Unit m
γ: Bulk density of materials, t/m3
5: Material running speed, m/S
- The calculation method of running speed of linear vibrating screen is:
v=kv*X*w*cos( δ) * https://www.xxhongda.net/ Vibration motor
https://www.cbzdq.com/ Wall vibrator [1+tg（ δ) tg(x) ]
- The calculation method of running speed of circular vibrating screen is:
V=kv * in * w2 * (1+) * a
Where, kv: comprehensive empirical coefficient, generally 0.75~0.95
λ: Single amplitude, in mm
w: Vibration frequency, unit: rad/s
δ: Vibration direction angle, in °
A: Inclination angle of screen surface unit °
- Dynamic load: P=k* λ
Where, k: spring stiffness, in N/m
λ: Amplitude in m
P: Dynamic load in N
The maximum dynamic load (resonant dynamic load) is calculated as 4~7 times of the above results
The main parameters of the vibration motor include vibration force, vibration frequency, amplitude, power and motor stages. The following is a brief introduction:
1、 The vibration form produced by a single vibration motor installed on the equipment is generally circular vibration without directivity, while the combination of more than two vibration motors
Use can produce a variety of vibration patterns.
2、 The most basic vibration elements are vibration frequency and amplitude, from which velocity (vibration frequency x amplitude), and acceleration (frequency
Square x amplitude)
3、 Vibration frequency
The unit of frequency is times/second,also called Hertz. In the vibration motor, it is determined by the number of poles and cycles
4、 Amplitude and acceleration:
In the vibration with the center of mass, the distance Ym from the center of mass to the maximum displacement is called the amplitude. In the vibration application, the distance S (double vibration）To express. In the vibration system using vibration motor, the determination of amplitude is very important.
When the motor is powered on and rotating, the exciting force generated by the exciting block is transmitted through the motor bottom angle or flange plate
Vertical and horizontal vibrating machinery. The vibration motor consists of a specially designed sub line package and rotor shaft, which can withstand high-frequency vibration. The horizontal vibration motor uses four sector eccentric blocks
As an exciting block, the angle between two eccentric blocks at the coaxial end can be adjusted to adjust the exciting force of the vibration motor from zero to maximum.
When the vibration motor is powered on and rotated, it drives the eccentric blocks at both ends of the motor shaft to generate inertial excitation force, which is a spatial rotation force with amplitude of Fm, Fm=mr.
W-a motor rotation angle frequency
w = 2πn/60
Vibration times of vibration motor
This is the calculation of vibrating screen capacity.
