How do you size a tank mixer?
In terms of the height of the mixing blade in your tank, the optimal height is to have the blade 1/3 the length of the tank off the bottom of the tank. For example, if you had a tank that was 24 inches tall, you’d want your blade to be 8 inches off the bottom of the tank.
How do you calculate mixer?
MIXING FORMULA
- D = blade Diameter.
- H = blade Height.
- N = Number of blades.
- RPM = Revolution Per Minute (shaft speed)
- 231 = Cubic Inches per gallon.
- V1 = Volume displaced per revolution.
- V2 = Volume displaced per minute.
- G = Gallons displaced per minute.
What is twin horizontal shaft mixer?
Twin Shaft Horizontal Batch Mixer Features N. Adjustable paddles and speed for flexibility to mix a wide variety of materials in an efficient manner. Sanitary design features with special shaft seals available. Cycle times as low as 1-1 minutes can be achieved with high-speed scale designs.
What is mixing tank?
A mixing tank is a container that is used to blend several components together. The material that a mixing tank is made of can range from plastic, glass or hard rubber to steel of all types. In most manufacturing facilities, the use of a mixing tank to prepare materials that will be used in production is common.
How is degree of mixing measured?
From these the degree of mixing is determined by equation Eq. (5) as follows(5) M l = S 2 − S r 2 S 0 2 − S r 2 , where Ml is the mixing degree, which should stay between 0 and 1. The exact value of Ml in any given state does vary depending on the amount of samples taken, and the size of the samples.
How do you measure the diameter of an agitator?
Agitator Dia ( D ) = D/T x Teq. Bulk Velocity ( Vc ) = 6 x Scale of Agitation ft/min. = 0.03048 x Scale of Agitation m/sec.
What is mixing intensity?
1. A certain minimum level of intensity is needed to achieve a good mix. That minimum level of intensity is dependent on ingredient characteristics and their interactions. 2. A fixed amount of energy is needed to disperse an equal amount of ingredients having the same characteristics to the same degree of homogeneity.
What is twin shaft mixer?
MEKA Twin-Shaft mixers are capable of blending materials with particle sizes of up to 150mm in diameter. The paddle angle of 45° also means it can withstand higher loads, therefore it is capable of mixing zero slump concretes, RCC mixes and all types of ready mixed concrete mixtures.
What equipment is used for mixing?
Our mixing equipment consists of three main categories which include laboratory shakers, mixers and rockers. Shakers are frequently used for sedimentation studies and some cell and tissue work. Shakers are designed to operate in a back and forth movement on a horizontal plane, often described as a shaking action.
How do you calculate mixing index?
M=σ20-σ2σ20-σ2r. Given the concentrations of the reference component in each cell, the mixing index can be defined and calculated by the statistical method. Lacey pointed out that this index is related to the number of the cells.
What is the mixing index?
Mixing index is a measure of the degree to which fluid flow will promote the dispersion of dissolved solutes or suspended materials in the fluid, leading to homogeneity. It is an indicator of the quality of the mixing process.
How to calculate the reference diameter of a helical gear?
The following is a calculation for the Reference Diameter of a helical gear with: Normal module m n = 2, Number of teeth z = 30, Helix angle β = 15° (R) Reference Diameter d = zm n / cos β = 30 × 2 / cos 15° = 62.117
How to calculate shaft diameter of an input shaft based on?
If you don’t want to do that just double the torque that you calculated using speed and power , and put that double torque into the next eq which calculates diameter or simple use the formula below: Dia = (480*power)/(pi square * RPM * Shear Strength) This will give you a safe shaft but might have some redundancy.
Where can I use an ex compliant gearbox?
Ex compliant standard gearboxes can be supplied against Groups 2 or 3 for surface industries in designated hazardous location Zones 1 and 2 for gases, vapours and mists; and in Zones 21 and 22 for dusts. ATEX Compliance Assured SERIES J
How big should a shaft to bearing fit be?
Ideally the shaft to bearing fit will be a “press fit”, also called “interferance fit”. In other words the diameter of the shaft is machined slightly larger than the diameter or bore of the bearing. A rule of thumb is .001 inches “interferance” per inch of diameter.
