DAVIS Mixers Are
Built In Five Levels of Construction
For mixing materials
weighing up to 150lbs. per cubic foot.

Designed and built for ingredients weighing up to 35 pounds
per cubic foot and operations that do not run their mixers over 4 hours per day. |
Designed and built for ingredients weighing 35 to 50 pounds
per cubic foot and up to 8 hours per day operation. |
Designed and built for ingredients weighing 50 to 70 pounds
per cubic foot and up to 8 hours per day operation. |
Designed and built for ingredients weighing 70 to 100 pounds
per cubic foot and up to 8 hours per day operation. |
Designed and built for ingredients weighing 100 to 150
pounds per cubic foot and up to 8 hours per day operation. |
NOTE: To
determine the actual weight per cubic foot of any product, simply weigh one gallon and
multiply the weight by 7.5.
The level of construction is determined by three
factors, the product's bulk density, the hours of operation, and the product's
flowability.
For operating times exceeding eight hours, we offer
foot mount speed reducers and shaft mounted speed reducers for up to 24 hours per day
operation. Consult factory for specific details. Also see our page titled simplified drives for more
information.
Free flowing products are typically dry granules,
powders or pellets. For products that do not flow freely, such as wet or fibrous
materials, we generally recommend the next level of construction higher than the product's
bulk density requires. Please consult factory for more specifics.
Standard Duty
Our Standard Duty Models are designed to mix
ingredients which do not exceed an average weight of 35 pounds per cubic foot. This can
include bird seed, charcoal, coffee, tea, and many plastic resin (polyvinyl chloride,
polyethylene) pellets. Certain ingredients may exceed 35 pounds, but as long as the total
batch doesn't, and the mixer is not operated in excess of four hours per day, our Standard
Duty Construction will provide many years of operation.
Heavy Duty
For mixing ingredients that average
35-50 pounds per cubic foot, or operations that run their mixer 4 to 8 hours per day, our
Heavy Duty model is required. As the weight per cubic foot of the items you mix increases,
the mixer's capacity is increased accordingly. To compensate for this added capacity we
use thicker steel in the mixer's tank, plus larger shafts, sprockets, chains, bearings,
etc. Ingredients which generally require this heavier construction include, but are not
limited to; cornmeal, light detergents, flours, rice, and minerals that do not
exceed 50 pounds per cubic foot.
Super Duty
Our Super Duty Mixers are built
considerably heavier in order to accommodate ingredients which weigh 51 to 70 pounds per
cubic foot. Products in this category include; many types of mineral mixes (bath salts,
foot salts, talc based mixes, etc.), fertilizer, detergents, as well as sweeping and
cleaning compounds. See note above for extending hours of operation beyond 8 hours
per day.
Ultimate Duty
Materials weighing 71 to 100 pounds
per cubic foot our Ultimate Duty Construction. Items in this range are; drywall products,
caulking, grouting, plaster, foundry sand, joint cement, cement powder. See note
above for extending hours of operation beyond 8 hours per day.
Maximum Duty
Ingredients averaging 100 to 150
pounds per cubic foot require Maximum Duty construction. Products mixed in the
Maximum Duty range include certain clays and sand, some metal ores, cement mixed with soil
for stabilization purposes, and many of the Ultimate Duty mixes in wet form. See
note above for extending hours of operation beyond 8 hours per day.
