There are many different mixers that you can choose from for your high viscosity materials. One of the very best types of mixers for this kind of material is a sigma blade mixer because it can be used for adhesives, rubber, and silicone. Sigma blade mixers find use in many different industries including the food industry and the industrial industry. There are mixers that allow for different applications, but if you have not looked into a sigma blade mixer, it is time to do so. Here are a few aspects of a sigma blade mixer that make it an excellent choice.
Built To Last
When you invest your money into a mixer, you expect to get a product that is going to see a lot of use, and be able to withstand that use. A sigma blade mixer is going to be able to provide you with extended use. They are built using a double trough stationary bowl with two sigma blades placed horizontally in each trough. These blades are then connected to a fixed speed drive. The construction allows for very little dead space when mixing high viscosity materials. The blades are stainless steel and are jacketed with carbon steel for heating and cooling applications. There are also bushings that allow for minimal friction in the rotation of the mixer. The stainless steel, carbon steel, and bushings allow for a long life of the mixer.
The drive is going to consist of a motor of type TEFC or TEFC flameproof gearbox. This gearbox can be customized for your specific task but will always be a suitable size and ratio. The mixer will also have spur gears that are of adequate size, and will be built with machine cut teeth that are between the front and the rear blade.
How To Work The Mixer
The mixer is designed to take materials from the top of the trough, and usually only about fifty percent of the volumetric capacity should be loaded in at one time. The fixed speed drive allows the blades to rotate. The blades are made to rotate at different speeds, so the mechanism of mixing is shearing. The material exits the mixer by either tilting the mixer, a bottom discharge valve, or through an extruder screw at the bottom of the two troughs. You can have the mixer customized with any one of these different discharge mechanisms.
