Simpson Mix-Muller Batch Mixer for Chemical Applications

While conventional mixing is usually adequate for the blending of easy to handle solids, only more intensive forms of mixing can produce total uniformity in a mix of materials having disproportionate mass, particle size, liquidity, viscosity or density. Simpson is here to assist you in reviewing wetted solids mixing options.

Over the last 110 years, Simpson Technologies has developed advancements and customizations for the chemical and industries by closely working with research-based organizations and clients. Simpson equipment provides strong repeatability, process control, advanced energy efficiency and safety.

Simpson Mix-Mullers have been successfully applied to a very large number of applications in the chemical processing industries including lead acid battery paste, animal feed, architectural stone, catalysts, ceramics/pottery, colored pigments, explosives/pyrotechnics, fertilizers, molecular sieves, mineral ores, pharmaceuticals, pigments, powdered metals, refractories, and welding rod flux.

With thousands of installations across the globe, Simpson has brought confidence, reliability, and increased productivity to several manufacturing sectors.

Description

Medium-speed, high-intensity, muller-type mixer for batch operation.

Application

Small- to medium-sized preparation systems, and the most difficult mixing applications.

Features

– Adaptive tooling
– Energy efficiency
– Larger batch and longer available cycle
– Rugged design

Versatility Makes You More Competitive

Designed to utilize a range of batch sizes and longer cycle times to provide better consistency and control. Longer cycle times provide for better control. Adaptive tooling provides for flexibility to adjust to variations in batch composition and property development.

Adaptive Tooling. Muller wheels are mounted on independent, spring-loaded suspensions. As the mixture increases in volume and strength, the mullers react by raising and increasing the mulling pressure. This is a versatile and inexpensive source of mixing energy which provides the kneading and compression action of mulling.

Wide-faced mullers provide compression and shear. The muller wheels are set slightly off their true radius so that as they revolve, they skid to provide a shearing action. The inside edges of the wheels travel a shorter path than the outside of the wheels which causes a spatulating action across the face of the wheels.

Interchangeable, modular plows armored with tungsten carbide provide intensive blending and minimize maintenance costs.

Simpson Customized Solutions For Your Needs

With the range of applications, there are a range of modifications for the Mix-Muller. Here are a few:

  • Standard Steel or Stainless Steel
  • Liquid Additions
  • Cooling/Heating Jackets
  • Dusthood
  • Wheel Scrapers/Crib Scrapers
  • Increased Motor Sizing
  • Special Design for Pyrotechnic Applications

Mixing vs Mulling

A concise definition of mulling would read “an intensive and controlled mixing process.” Mulling action is a combination of controlled pressure and agitation, to achieve a high degree of uniformity in the preparation of two or more dry/solid or wetted/solid materials rather than agitation alone.

Mixing

A mixer for combining solid materials usually operates with a stirring or beating action effected by blades, paddles, arms, or flighting. The normal action of this type of mixer though adequate for simple blending tasks, is not suitable where tempering action, strict uniformity or the intimate blending of a relatively small amount of material into a large mass, is desirable.

Mulling

The muller is used where materials of disproportionate mass, density, viscosity or particle size must be evenly dispersed to form a homogenous mass without segregation/or where a small amount of one or more materials must coats each grain of a larger mass.

The Mix Muller and Multi-Mull operate on the same principles.
Energy Efficiency Utilizing 3 Forms of Energy:

  • Electric by Motor
  • Mechanical by Loading Spring
  • Gravitational by Weight of Wheel
