Sound Power Level Calculation Where: P1 is upstream pressure (bara) P2 is downstream pressure (bara) W is flow rate (kg/s) T is the upstream temperature (K) Mw is molecular weight (grams/mol) SFF is a correction factor to account for multiple occurrences of sonic flow in a line. If consecutive sonic conditions exist, then SFF=6; otherwise SFF = 0.
· Screening efficiency is calculated as the percentage of the undersize materials passing through the openings divided by the percentage of undersize in the feed. For example, if a screen is only 75 percent efficient, then 25 percent of the material within the desired product range is being rejected with the oversize material. Vibrating screens must be properly .
The discrete element method (DEM) allows for the calculation of the dynamic of the ore. In this paper, two 2D threedegreesoffreedom dynamic models for a vibrating screen are tested, using linear and nonlinear approaches for angular displacement. These models consider the inertia of the ore and the ore force calculated with DEM.

The vibration in the screen are generated by unbalanced weight of calculated design. The vibrating shaft is made of special alloy steel with streamlined stress design. The shaft is designed in such a way so that there is no stress concentration at any point. This increases the fatigue life of the shaft. The revolving weights are properly covered.
In order to introduce the mechanical characteristic of rubber spring of vibrating screen,and labor the characteristic of start and parking,give the methods and formulas for designing and calculating of rubber spring,all of these can be available for reference and appliion when design the rubber spring of vibrating screen.

The blast vibration calculator can be used to estimate airblast overpressure and groundborne vibration at a specified distance away from a blast of known maximum instantaneous charge. An Overpressure or AirBlast Overpressure can be defined as the increase in pressure caused by a shock wave over and above normal atmospheric pressure.
Calculation of Spring Constant Consider a leaf spring inclinded at an angle y to the horizontal and fixed to a base at point D and to a bowl at point A, as shown in Fig. 2. Let O be the center of the circle (named base circle) which is inscribed tangent to the .

· one such equation from an English rule published at NewcastleunderLyme in 1868 is mentioned below. X= 20,000 Where X= breaking load of gear tooth in pounds p= pitch of teeth in inches f= face width of teeth in inches
Check angle of inclination with manufacturer's recommendation. If inclination is variable, allow for + five degrees variation from manufacturer's average specified adequate clearance between screen and stationary parts in accordance with manufacturer's specifiions.
Structural Design Calculation For Vibrating Screen. 2 add structural damping 123 vibration isolators consider a vibrating machine bolted to a rigid floor figure 2a the force transmitted to the floor is equal to the force generated in the machine the transmitted force can be decreased by adding a suspension and damping elements often called vibration isolaters figure 2b or by.
Screens are available in a single motor design for elliptical motion or a dual motor design for linear screening and can work with either a horizontal or incline setup. Each vibration method ensures the particles passing along the screen, if small enough, will have the opportunity to fall through the screen mesh between the start and end of the deck. Each style comes in .
This calculation is comprehensively outlined in Shigley's Mechanical Engineering Design (commonly referred to as "Shigley" by many engineers). This calculation method follows along with Shigley and uses seven steps as outlined below: Load characterization Static Analysis Material properties Calculate the fully corrected endurance strength
