Canada "The Process Equipment People"
designs, engineers and manufactures Ribbon and Paddle Mixers
for numerous different industrial and chemical processes and
Backed by almost a century of service to
the chemical, food, paint, petroleum, drug, plastics and other
process industries, PATTERSON Standard and Heavy-duty Ribbon
and Paddle Mixers are outstanding for economical and dependable
performance. The PATTERSON line of quality mixers includes
standard and custom models for laboratory, pilot plant and
production mixing of powders, pastes and liquids; jacketed
design for heating or cooling; twin-shaft paddle mixers; special
units for vacuum service; cylindrical mixers and heavy-duty
models for special chemical service. Standard sizes range
in working capacity from 0.8 cu. ft. to 282 cu. ft. (0.023
cu. m to 8.00 cu. m).
PATTERSON Mixers are fabricated in heavy gauge carbon steel,
stainless steel, nickel, monel or other special materials
as required. Every aspect of the design is planned for operating
efficiency under a variety of conditions. PATTERSON Mixers
are built for long, trouble-free service life. Our welders
are ASME qualified for code welding on unfired pressure vessels.
Mixing Action. PATTERSON Ribbon Mixers are engineered for
fast and thorough blending. The diameter, pitch and width
of each ribbon is accurately proportioned to prevent localized
product accumulation and achieve maximum action. Functions
include rolling, folding, reversing direction, vertical displacement
and lateral displacement operations.
In addition to the mixing action, the shearing action in
the interface between the opposingly pitched ribbon provides
a mild kneading. The Mixer Ribbons are designed so that the
outer ribbon conveys from the end towards the centre whereas
the inner ribbon conveys from the centre towards the end.
PATTERSON Paddle Mixers or Pug Mills are used for continuous
mixing of a wide range of materials of medium to heavy viscosity,
where dry material is mixed with binders or liquids.
Design features single or double shafts with adjustable pitch
bolted-on paddles available for various mixing requirements
such as chocolate, batters, semi-plastic mixes, pastes, glues
- Fast, Easy Cleaning - The entire ribbon or paddle assembly
is removable as a unit.
- Outboard, Anti-friction Bearings - The trunnions are supported
in self-aligning, anti-friction bearings mounted outboard
of the mixer body.
- Shaft Seal - Three rows of packing, of type compatible
with product and application, housed in a standard gland
follower stuffing box, assist in keeping dirt out and product
in. Purged and lubricated seals as well as the mechanical
seals are also available.
- Hinged Covers - Sturdy steel covers with hinged end sections
and bolted centre section permit charging at either end.
Special cover arrangements accommodate automated feed devices
post tight operations and other specific customer requirements.
Bag support grids with or without bag slitters, and limit
switch protection, are available for operator safety.
- Simplified Drives - Typically units of sizes to 100 cu.
ft (2.8 cu. m) and 15 H.P. drive are driven by a torque
arm reducer with "V" belts and an integrally mounted
motor. Larger sizes incorporating chain drives have a separate
motor-reducer drive arrangement mounted on a common base
- Many of our units are equipped with integral gear motor
shaft mounted drives for requirements up to 30 HP and either
parallel shaft or right angled helical gearmotors for drive
requirements over 30 H.P. This not only provides greater
drive efficiency but also improves operator safety by eliminating
the pinch points created by belt and chain type arrangements.
Maintenance is reduced by the elimination of stretching
and wearing of the belts, chains, and the continual tensioning
- Controlled Liquid Additives - Strategically positioned
spray nozzles permit controlled addition of liquids.
- Dependable Discharge - Manual lever or hand wheel operated
slide gate valve, with air cylinder operator as an option;
or swing-type flush mounting plug valve which eliminates
the amount of product contained within the pocket of valve
nozzle that is experienced with the slide gate type of valve,
provide dependable discharge.
