HORIZONTAL PLOW MIXERS – BATCH AND CONTINUOUS
View General Arrangement Drawings

HORIZONTAL MIXERS
Littleford Horizontal Ploughshare® Mixers create a mechanical fluidized bed mixing action. The mixing tools project and hurl material away from the wall into free space in a crisscross direction, and inversely back again.
As appropriate for the application, the size, number, geometric shape, arrangement, and peripheral speed of the mixing tools are designed to achieve the action. The plow separates and lifts the product into three-dimensional motion, while the number and arrangement of the tools insure agitation back and forth along the length of the vessel. When required, the mix action is assisted by high shear chopper devices--independent high-speed motors with customized blades for adding shear to the product mix.
BATCH MIXERS (FKM SERIES)
Littleford FKM Series Ploughshare® Batch Mixers are used in various process industries for mixing applications with products that include solids to solids, liquid to solids, and paste materials. The mixers are offered in standard production sizes ranging from 11 cu. ft./300 liters to 883 cu. ft./25,000 liters, total capacity. Laboratory sizes for process development and formula optimization are available.

Littleford Ploughshare® Batch Mixing provides better control as follows:

  • Thorough dispersion of minor ingredients
  • Controllable dispersion of liquids
  • Improved temperature control
  • Homogenous mix regardless of differences in raw material densities and/or particle size

Littleford Day, having pioneered recording energy input in conjunction with the plows and choppers has elevated processing from an art to a science, which provides high efficiencies, enhanced output, and repeatability. Many customers in the pharmaceutical industry are utilizing this technology as part of their validation process.

Laboratory sizes for process development and formula optimization are available.

CONTINUOUS MIXERS (KM SERIES)

The Littleford KM Series Ploughshare® Continuous Mixer utilizes the same processing technology as the Littleford FKM Series Ploughshare® Batch Mixer, but provides this in a continuous flow. Littleford KM Series Ploughshare® Continuous Mixers are primarily used where high volume production is a pre-requisite in the processing of dry products and dry products with liquid additions and product granulations.

The Littleford KM Series Ploughshare® Continuous Mixer is charged through a port mounted on the topside of the charging end of the mixer. Typical working level of the product is nominally 50% of total capacity. As in the case of the Littleford FKM Series Ploughshare® Batch Mixer, elements put the product into 3-D motion, resulting in a superior mix achieved during a short retention period. Discharge of product is through an adjustable weir control valve at the opposite end of the mixer from where the product was charged. Discharge through a port on the bottom for products that are sticky or cohesive are available as well. Standard sizes are 11 cu. ft. / 300 liters to 883 cu. ft. / 25,000 liters.
