Sigma blade mixers are used for mixing and discharging liquid materials. They are suitable for many applications including metal finishing, electroplating and anodizing, printed circuit boards and others. They also meet the requirements of NASF standards. Here are some points to keep in mind when choosing Sigma blade mixers.

Discharge arrangements for sigma blade mixers
There are several types of discharge arrangements available for a Sigma blade mixer. These are dependent on the product characteristics and the need for process containment. The three basic types of discharge arrangements are:
- Tilting discharge (which rotates the bowl at about 110 degrees)
- Bottom discharge (where material is discharged into a separate vessel). This type is the most common and is best suited to mixing heavy masses. The bottom discharge valve can be hydraulically operated or powered by a pneumatic arrangement.
- Overlap discharge. This type of mixing involves using two sets of blades that overlap. This design promotes quick material exchange while reducing shearing.

Sigma blade mixers are designed to handle a viscous material, and their blades are designed to promote transverse and lateral motions. This allows the blades to mix the mass by folding, pulling, compressing, and shearing it. For this reason, a Sigma blade mixer can be a great solution for mixing viscous materials.
The mixer’s vacuum capacity is typically 40 to 65 percent of its total volumetric capacity. The mixing blades are rotated by heavy-duty drive systems, including a motor, gearbox, and couplings.
High-capacity mixing performance
The Sigma blade mixer is an extremely versatile piece of equipment like the horizontal grinder equipment, and is capable of high-capacity mixing. This industrial mixing machine is precision-built with anti-friction bearings. The blades of the Sigma blade mixer rotate at different speeds to provide mixing and shear effects. This feature is particularly useful when working with materials with a high viscosity. These mixers are available in both full-size and portable versions.
The Sigma blade mixer is designed for intensive mixing, including kneading and plasticizing. They are highly efficient, requiring less energy than double or triple-planetary mixers.
Sigma blade mixers are known for their high user-friendliness and process flexibility. They are available in a range of sizes and can be used for lab, pilot, and production batch mixing. They can also be equipped with safety features like PLC controls and dust/vapor tight jackets. Additionally, they are compact and easy to clean.
A Sigma blade mixer is a powerful machine that combines kneading, mixing, vulcanizing, and polymerizing. It uses two “S”-shaped blades and a screw extruder to mix a material evenly. The mixer’s speed and helix angle are adjustable so that the mixing process can be tailored to meet specific needs.
To maintain Sigma blade mixers, you need to know how to take care of these powerful appliances. These mixers require a high amount of power and can be prone to dead spots. Luckily, there are a few maintenance tips to keep these appliances in tip-top condition.
The first thing to do is to ensure that you adjust the blade speed properly to avoid dead spots. This will prevent your mixer from leaking volatile solvents during mixing. Moreover, it will allow you to mix sticky or very viscous materials without causing the loss of volatile solvents.
