Pneumatic Conveying

Air velocity calculator	Technical article	Excel calculator
This calculator allows to calculate the air velocity in a pipe of a given diameter, for a given flowrate. It also allows to calculate the velocity at the beginning and end of a pipe which is convenient in pneumatic conveying applications.

Airlock rotary valve sizing calculator	Technical article	Excel calculator
This calculator allows to calculate the size required for an airlock rotary valve to meet a given duty, knowing the flow characteristics of the material to handle

Bag filter sizing	Technical article	Excel calculator
This calculator allows to calculate key design data for the conception of a bag filter, for instance air to cloth ratio, can velocity, intersticial velocity, and the area of filtration required

Dilute phase pneumatic conveying capacity calculator (air only method)	Technical article	Excel calculator
Calculator to determine the capacity of a lean phase (dilute phase) pneumatic conveying system. It uses the "air only" method.

Dilute phase pneumatic conveying capacity calculator (Rhodes method)	Technical article	Excel calculator
Calculator to determine the capacity of a lean phase (dilute phase) pneumatic conveying system. It uses a method proposed by Rhodes.

Dilute phase pneumatic conveying capacity calculator (Zenz-Othmer method)	Technical article	Excel calculator
Calculator to determine the capacity of a lean phase (dilute phase) pneumatic conveying system. It uses a method proposed by Zenz-Othmer which decomposes the piping in several sections.

Cyclone design calculation tool (simplified method)	Technical article	Excel calculator
This calculator allows to estimate the size of a cyclone for a particular application. It is a simplified version of the method of Bohnet.

Cyclone Efficiency Excel calculator	Technical article	Excel calculator
This calculator allows to estimate efficiency of a given cyclone geometry when it is applied a certain load

Dense phase conveying scale up	Technical article	Excel calculator
This tool allows you, from the result of a pilot plant data, to estimate how should be sized the scaled up system for a particular application

Screw conveyor design

Screw conveyors capacity calculation	Technical article	Excel calculator
This calculator allows to estimate the capacity of a screw conveyor (screw feeder) based on screw conveyor characteristics and product characteristics

Powder flowability Calculations

Angle of repose calculator	Technical article	Excel calculator
The angle of repose is one of the basic way to represent the flowability of powder. This calculator helps you to calculate the angle of repose of a component, having done an experiment 1st.

Bulk powder discharge rate estimation tool	Technical article	Excel calculator
This Excel calculator allows to estimate the discharge rate of a hopper by gravity through different equations like Beverloo, Carleton, Johannson

Powder flowability estimation tool	Technical article	Excel calculator
This tool is grouping different methodology to help estimating how flowable a powder is. Calculation of angle of repose, Carr Index and Hausner Index.

Dust explosion protection

Dust explosion vent calculation	Technical article	Excel calculator
This calculator allows to estimate the size of the vent to protect a hopper in case of explosion. The tool is only to give a 1st idea, sizing of such sensitive equipment must be done with a specialized company.

Powder mixing

Froude number Excel calculator	Technical article	Excel calculator
This calculator allows to calculate the Froude number. The Froude number is an adimensional number that is used to define the flow characteristics inside a mixer.

Grinding and milling

Grinder powder consumption calculation	Technical article	Excel calculator
This calculator allows to calculate expected power consumption required for a particular application, based on grindability data of the feed

Vibrating screen size calculation (mining)	Technical article	Excel calculator
This calculator allows to estimate the required size of a vibrating screen considering the flowrate of bulk soilds to sieve, and the screen characteristics (VSMA method)

Vibrating screen Discharge End Depth Bed calculation (mining)	Technical article	Excel calculator
This calculator allows to estimate the depth of material bed at the end of a vibrating screen considering the flowrate of bulk soilds to sieve, and the screen characteristics (VSMA method)

Spray Drying

Spray dryer heat and mass balance calculation tool	Technical article	Excel calculator
This calculator allows to estimate a spray dryer efficiency based on the feed, outlet product, inlet air, outlet air product and process parameters
