Motor Sizing Calculations

Selection ProcedureTorqueSpeedThe first step is to determine the drive mechanism for your equipment. Some examples are direct rotation, a ball screw, a belt and pulley or a rack and pinion. Along with the type of drive mechanism, you must also determine the dimensions, mass and friction coefficient, etc. that are required for the load calculation: 1. Dimensions and mass (or density) of load 2. Dimensions and mass (or density) of each part 3. Friction coefficient of the sliding surface of each moving part Next you will need to determine th

Hammer Mill Crusher Grinder

ScopeAdvantagesPurposeExampleSignificanceMechanismRatingsEffectsTechnologyOperationConstructionUseThe hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher and in these machines impact is supplemented to a substantial degree by a positive and powerful sledging action by teeth which are rigidly attached to

2017-6-29  Looking at the system with a 200mm discharge pipe, the flow rate more than doubles up to 167.5m3/hr with little effect on pump head, a small increase in pump power, but a significant increase in pump efficiency from 29.9 per cent to 55.8 per cent. Increasing the discharge pipe diameter to 250mm yielded even higher flow rates and better efficiency.

CalcTool: Gravity-fed pipe flow calculator

This calc is mainly for pipes full with water at ambient temperature and under turbulent flow. If you know the slope rather than the pipe length and drop, then enter "1" in "Length" and enter the slope in "Drop". If the cunduit is not a full circular pipe, but you know the hydraulic radius, then enter (Rh×4) in "Diameter".
