FEECO horizontal mixers offer an ideal solution for homogeneously blending solid and liquid feed components into uniform bulk solids mixtures according to the unique needs of the process industries.
Our innovative mixing technology is used throughout a variety of industrial applications to mix, condition, de-dust, and even agglomerate powders and sludges for improved density, flowability, transportation, handling, and application. These horizontal mixers also serve as an engineered alternative to horizontal ribbon mixers and mixing screws, offering significantly improved blending of solid and liquid components.
Within our extensive line of processing equipment, we offer two primary types of horizontal mixers, each with highly customizable configurations for accommodating different product goals and production capacities. All FEECO equipment is backed by our unmatched expertise in processing bulk materials.
PIN MIXERS
Pin mixers are a medium-shear horizontal mixer ideal for processing ultra-fine or powdered materials in the presence of a liquid binder or minor liquid additive.
Pin mixers utilize a high-speed mixing action to densify particles into rough or free-flowing agglomerates. They are widely employed for processing carbon black and coal, as well as a variety of materials in the chemical industry.

PUGMILL mixerS
Also known as paddle mixers or pug mills, pugmill mixers are another type of medium-shear horizontal mixing equipment. Pugmill mixers offer a high-torque, gentle blending action compared to pin mixers, imparting a kneading and folding action on the material to homogeneously blend solid and liquid feed materials. They can be used with a wide variety of materials and are especially valued in mixing operations processing challenging materials that require a heavy-duty solution; pugmill mixers have become essential in processing copper concentrates, as well as steel mill by-products, animal feed products, fly ash, and even digested dairy manure.

Both types can be used as stand-alone units, or as the preconditioning step in a larger agglomeration/granulation setup. In addition to standard designs, FEECO mixers are highly customizable. This includes the ability to customize aspects such as trough size, agitator design, motor size, reducer, drive assembly, seals, shaft speed, and more for a highly efficient result. Each type is also easily automated for seamless production.
TESTING
The FEECO Innovation Center is a unique process engineering facility where we can test pin and pugmill mixers at batch and pilot scale to determine which type of horizontal mixer will best suit the material, as well as work out variables in process design and scale-up for optimal efficiency. This includes defining:
- Requirements for a continuous mixing process
- Parameters necessary to achieve complete mixing and a homogeneous blend (where desired)
- Configuration needed to generate optimum product quality
Formulation can also be assessed as part of the testing process.
Parts & Service
In addition to engineering and manufacturing custom horizontal mixers for hundreds of applications, we can also provide an array of parts and service support to help keep your pin mixer or pugmill mixer running its best. This includes:
- Annual inspections
- Process and equipment audits
- Routine maintenance and field services
- Spare parts
