2021 Roto-Mix® Compost Mixers Stationary 920-18

Model 920-18 Rotary Industrial Series Compost Mixer

The 920-18 horizontal rotary compost mixer has a mixing capacity of 920 cu. ft. and can hold a maximum load up to 26,100 lbs. It is designed to thoroughly mix materials to ensure rapid decomposition to produce quality compost. This rotary compost mixer, equipped with the patented GeneRation II Staggered Rotor Mixer, will uniformly blend materials in a tumbling action that does not pack material and helps introduce air into the mix. The rotor lifts the material past the wedging point of the lower side auger, resulting in a aerated mixture while lowering power requirements. Total movement of material in the mixing chamber eliminates dead spots that are common in conventional auger mixers. Available in truck, trailer or stationary units. This size of mixer works well with medium to larger composting operations.

Features may include:

• Higher side discharge location allows easier loading of conveyors or elevator legs while maintaining a minimum mixer height.

• Left and right discharge units available.

• Low electric horsepower requirements.

• Flexible motor mount designs to keep overall space requirements to a minimum.

• Wide base scale frame.

• The rotor design lifts ingredients up to the side augers that move ingredients end-to-end for a fast thorough mix. Unlike the wedge point on other brands, our rotor lifts the material past the wedging point of the lower side auger, giving you a fluffier mixture while lowering power requirements. Total movement of material in the mixing chamber eliminates dead spots common in conventional auger mixers.

• The ROTO-MIX system protects particle size with less grinding or compaction. Particle size and porosity are critical because it determines how well air can enter and diffuse into the composting mass.

• With better air introduction and distribution, ROTO-MIX consistently produces quality compost by lifting the ingredients past the lower auger’s wedge point, resulting in a fluffier mixture that starts to compost faster.

• Our thorough mixing action eliminates dead spots, auger tunneling and corner pile-up giving a consistent balance of nutrients and microorganisms from the first yard of compost to the last.

• Mixes all types of compost ingredients, solid waste, yard waste, food waste, sludge and amendments, animal manure and a number of others with consistency day after day.

• Load-cell mounting comes standard with ROTO-MIX ball and socket type tie bars to connect the mixer to the frame. This feature eliminates side and end movement on the load cells, which allow for scale dependability and accuracy.

• The forward pitch rotor design, adjustable UHMW wiper blades, and the rotation of the lower auger quickly and efficiently cleans out the mixing chamber.

• The single lever latch makes inspection easy and desirable compared to other little latches or hardware.

• Allows quick lubrication from a single point. Heavy- duty drive assembly runs in an enclosed oil bath.

• A lower center of gravity makes for a more stable unit when making windrows and less shock load when cornering.
