PREFACE P-1
General Information
Introduction
Purpose and Use
The Chandler Engineering Model 3260 Constant Speed Mixer is designed to provide mixing
of cement slurries in accordance with API Specification 10. The mixer features a digital
speed control and display with a built-in tachometer and programming capabilities. The
built-in programs are set for mixing speeds of 4,000 and 12,000 RPM for use with the 1-liter
cup. Alternately, the mixing speed may be adjusted manually via the built-in keypad. As the
load varies, the speed control maintains the speed of the motor at the preset speeds.
The control enclosure is mounted below the mixing cup and motor for ease of use and
display of the mixing speed.
Features and Benefits
•CE certified.
•Constant speed operation is easily observed by the digital display.
•Hardened mixing blades assure long life.
•Four pre-programmable constant speeds, with two pre-programmed speeds (4,000
and 12,000 rpm). The preset speeds can be easily changed to any value between
1,000 and 20,000 rpm for applications outside API Spec 10.
•Push button selection of variable speed allows mixing of shear-sensitive materials at
desired speed.
•One continuous variable speed (1,000 to 20,000 rpm).
•Stainless steel container can withstand abrasive action when mixing cement at high
speeds.
•Heavy-duty industrial-grade mixer assures its trouble-free and long life operation.
•No variation in thickening time test due to changes in shear rate.
•Operator can quickly select API speeds while adding cement to mixer.
