Cementing Constant Speed Blender Model HDT-3070

Cementing Constant Speed Blender Model HTD-3070

The Rigchina Model HTD-3070 Cementing Constant Speed Blender facilitates the preparation of oil 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. 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 RIGCHINA Model NRC-1616 provides a means of consistently preparing cement slurries for testing purposes and can also 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. The "START" switch is pressed and the cement is immediately added to the mix water in less than 15 seconds. The rotational speed is automatically increased to 12,000 RPM and the slurry is mixed an additional 35 seconds. A microprocessor maintains the rotational speed and is independent of fluctuations in line voltage and the viscosity of the cement slurry.

Features and Specifications:

• Hardened stainless steel mixing blades

• Stainless steel 1 liter mixing container

• Two preset mixing speeds and variable speed

• Rotational speed is maintained at set point with microprocessor

• Timing relays automatically control mixing times at required RPM

• Digital instrumentation provides excellent readability

• Optional Torque Measuring Module tests crosslinking time for fracturing fluids
