The NT-CE5880 is a laboratory mortar mixer designed for the preparation and mixing of cement and mortar for laboratory testing, quality control, research, and development applications. Developed to meet high standards of quality, reliability, and repeatability, the mixer complies with applicable international standards and is suitable for a wide range of construction-material testing applications.

Operating Principle

The mixer features a planetary mixing mechanism, in which the mixing paddle rotates around its own axis while simultaneously orbiting around the mixing bowl. This combined movement provides efficient and homogeneous mixing of the materials.

The bidirectional mixing action ensures optimum mixture homogeneity and excellent test repeatability, making the equipment particularly suitable for standardized laboratory testing.

Key Features

Programmable Mixing Cycles

The microprocessor-based control system allows users to select and program different mixing cycles according to the requirements of the following standards:

• TS EN 196-1
• TS EN 196-3
• ASTM C305

This programming capability enables standardized testing with precise and repeatable mixing parameters.
