Dispersing and Mixing Blades

Norstone offers a wide variety of industrial dispersing blades in stainless steel, hard-coated various polymers, and other alloys. Dispersion blades feature alternating outer teeth with angled leading and trailing edge profile for high shear action. Their teeth sharpen with use, and the number of teeth will increase with the blade size.
Dispersion blades convert input energy primarily to shear and in turn produce a different result than flow-driven agitation processes.  When used at recommended tip speeds driven by sufficient horsepower, these commercial mixing blades quickly turn pigments into paints, break down solids into liquids, and more.  All styles are available, as well as technical assistance to make sure you are using the appropriate impeller for the process.  If you don’t see it here, it doesn’t mean we don’t have it!

Recommended where high shear is required for a rapid and smooth blend or when high shear is not required but is not detrimental. Blade should be 1/2 – 1 full diameter of the bottom of the tank with at least twice as much above the blade or it will suck in air. Tip speed should be 3500 – 4000 fpm. Blade should be 1/3 the tank diameter for medium viscosity and 1/2 the tank diameter for high viscosity.

Rules for the ITT blade are as follows:

  • 1/2 – 1 full blade diameter off bottom with 1.5 – 2 blade diameters of fluid above the blade
  • 3500-4000 fpm tip speed
  • blade size should be 1/3 diameter of tank for standard materials, high viscosity can take up to 50% the diameter of tank

Type 12 Propeller Blade

This is a very common mixing blade similar to a boat prop which mixes material in one direction. It is a standard used in most applications. However, there are many blades styles currently available which are superior to this technology. They have limited reach. They get very heavy as they get larger. The left handed design is good for de-aeration.

PTFE Prop

Type12ALabPropBlade

Lab Propeller blade

Type 13 Standard Axial Flow Turbine

This is the most common slow speed mixing blade. The arms of the blade are usually set at a 45 degree angle. Several blades can be stacked on one shaft so that this blade works well in a tall tank. The blade pushes product down and then out creating a rolling action. It can be designed to pump up. It is relatively inexpensive. A split hub design is available.

Type 13SH Split Hub Standard Axial Flow Blade

This is the most common slow speed mixing blade. The arms of the blade are usually set at a 45 degree angle. Several blades can be stacked on one shaft so that this blade works well in a tall tank. The blade pushes product down and then out creating a rolling action. It can be designed to pump up. It is relatively inexpensive. A Split Hub Design is available.

Bolt On Unassembled

This is one of the newer designs in mixing blades. It has a similar action to Standard Axial Flow but uses less energy. It is a higher price but works well at slow and high mixing speeds in viscosities less than 1000 cps. A split hub design is available.

Type 14 3-Bladed Plastic High Efficiency Axial Flow

Hydrofoil Blade Lab MD

Type 15 Straight Radial Turbine

This blade moves product to the outside only. The arms of the blade are set at 90 degrees. This style is commonly used at the bottom of the shaft of a square shaped tank. It draws a lot of power and does not move product efficiently. A split hub design is available.

Lab Radial Blade

PTFE Radial Turbine

SBT030037(1)

This blade moves the product into the center and then pushes it out to the sides with an aggressive whipping action. It has a high amp draw and provides good mixing of particles. The blade can be expensive compared to other types but is excellent for sweeping corners of a square tank. A split hub design is available.

Type 17

This blade is designed to fit through the bung hole in a closed head drum. As the shaft spins the end pieces open up into the shape of an axial flow blade. It is critical that the shaft speed and horsepower can move the blade fast enough to open up. This blade attaches to the shaft with collar and set screw.

Type 18

This blade is used for mixing high viscosity materials. A scraper blade can be attached to the blade for scraping the side or bottom of a tank.

Type 18B

Lab version of Type 18A

Type 19 Bowtie Blade

This blade is another style which is used for mixing high viscosity materials.

Type 20 TRN Blade

This blade is a new style of mixing blade. Although it looks simple, this blade has an unexpectedly powerful ability to mix low to medium viscosity materials. This blade runs at low tip speeds. Two blades may need to be required to ensure that product at the bottom is incorporated into the batch.

Type 21 Plunger Blade

This blade is used for mixing. Material of construction is Zinc-Aluminum Alloy complete with shaft. Sizes available are 1", 2″, 3", 6″, 8″ and 12″. This blade is very economical.

Type 23 Disk Turbine

This blade is primarily used for mixing gases or gases with liquids.

Banana_blades_lrg

Also known as “banana” style blade, this blade is used for mixing inside of flasks and other long neck type bottles.

Type 25

Also known as Ring Blade, this blade consists of three plates welded together with “cutting teeth” in between. Provides excellent shear using the Venturi principal. Requires a 6000 fpm tip speed. Trial sizes available.

Rules for the Hockmeyer D blade:

  • 1/2 – 1 full blade diameter off bottom with minimum of 2 blade diameters of fluid above the blade.
  • 5800 fpm +/-5% tip speed
  • Blade size should be 1/4 diameter of tank for standard materials, high viscosity can take up to 40% the diameter of tank.
  • Viscosity Range: 1000 CPS to 10,000 CPS. We have used the D blade up to 50,000 CPS and lower than 1000 CPS depending upon specific gravity.

Type 26

Also known as “coverings” blade, this blade is used mostly with hand held mixers for stirring heavier products such as flooring compounds, cement, ceramic and caulks.

Cement Mixing Blade

Lab Anchor Blade

Type 27

The anchor blade can be used as shown or have additional vertical resistant bars to be made into what is called a gate blade. This blade is excellent for moving high viscosity material in a radial direction and also good for keeping the outer limits of the batch in motion.

Plastic Lab Anchor Blade

CSI Blade

Also known as Ring Blade, this blade consists of three plates welded together with "cutting teeth" in between. Provides excellent shear using the Venturi principal. Can be difficult to clean and difficult to determine when worn. It is also very expensive but still very effective.
