OFITE’s Model 20 Constant Speed Blender was designed to prepare well 

cements for testing according to the guidelines stated within API Specification 

10. Research has demonstrated that the properties of well cements are 

highly dependent upon mixing procedures. In addition, studies have indicated 

that when constant speed blenders/mixers are used, data obtained from 

thickening time tests has greater reproducibility and generally correlates 

better with data obtained from other laboratories. The Model 20 was designed 

to provide a means of consistently preparing cement slurries for testing 

purposes and can be utilized to mix cements according to the procedures 

stated by the API.

The proper amount of mix water is carefully weighed and poured into the 

mixing container of the blender. The rotational speed is set to 4,000 RPM 

and allowed to stabilize at this speed. The “TIMER” switch is pressed and 

the cement is immediately added to the mix water. The cement should be 

uniformly added to the water in less than 15 seconds. After 15 seconds the 

rotational speed is automatically increased to 12,000 RPM and the slurry is 

mixed an additional 35 seconds. A microprocessor is utilized to maintain the 

rotational speed within the recommendations established by the API and is 

independent of fluctuations in line voltage and the viscosity of the cement 

slurry.

The 120-60-F Constant Speed Blender is intended for testing Fracturing 

Fluids. The rotational speeds are set to 500 and 1,000 RPM respectively.
