Before understanding the calculation method of the processing capacity of the vibrating screen, first of all, we must have a certain understanding of the variables that will affect the screening efficiency of the vibrating screen. In the actual screening and removal process, the processing capacity of the vibrating screen is affected by many factors. These variables are mainly: the average thickness of the material on the screen surface, the bulk density of the material, the size of the screen machine, the frequency of the vibration motor, and the inclination angle of the screen surface. Angle etc.
Calculation method of material running speed of vibrating screening machine
Before calculating the processing capacity of the vibrating screen, we must first have an accurate control of the running speed of a specific material (indicated by v), which also has an established calculation formula. According to the different models of the vibrating screen, the calculation formula of v It is also different, the specific calculation method is as follows:
1. Calculation method of material running speed of linear vibrating screen:
v=kv*λ*ω*cos(δ) *[1+tg(δ)*tg(α)]
2. Calculation method of material running speed of circular vibrating screen:
v=kv*λ*ω2*(1+ )*α
Where kv: comprehensive experience coefficient, generally 0.75～0.95
λ: single amplitude, unit mm
ω: vibration frequency, unit rad/s
δ: vibration direction angle, unit °
α: the inclination angle of the screen surface unit °
Calculation method of processing capacity of vibrating screening machine
After determining the running speed of the material on the screen, we can proceed to calculate the processing capacity of the corresponding vibrating screen. The specific calculation method is as follows:
Q=3600*b*v*h*γ
Where Q: processing capacity, unit t/h
b: Width of the screen, in m
h: average thickness of material, unit m
γ: Bulk density of materials, unit t/m3
v: material running speed, unit m/s
The above is the calculation process of the entire vibrating screen processing capacity, which is the basis for measuring the efficiency of the vibrating screen. However, these calculation formulas are only calculations of the processing capacity of a screening equipment under ideal conditions. In the actual screening process, factors such as uneven feeding and looseness of the screen surface will have a negative impact on the processing capacity. .
