KHD Test Center

Laboratory Analyses – Materials Testing – R & D

The competence and reliability of KHD´s test center is based on:

• Staff – experienced in the areas of cement process technologies and coal & minerals processing.
• Equipment with a broad range of facilities for analyzing and testing the broad variety of the relevant materials in laboratory, bench and large scale.
• Laboratory techniques and test procedures, partially developed by KHD but all tailor-made.

The results of chemical and physical analyses and testing provide a basis for:

• optimization of raw mix designTestcenter Cement 2
• process flowsheet development
• provision of layout data for plants and machinery
• safeguarding of warranties

Chemical and physical laboratory

Laboratory analyses at KHD test center comprises the latest methods and procedures applied to raw materials, intermediate, products, and solid fuels. Chemical and physical testing of the materials related to the cement production process:

• Chemical analyses
• Fuel analysesTestcenter Cement 3
• Particle size analyses
• Determination of absolute density
• Determination of mass-related surface (BLAINE)
• Grindability tests according to Zeisel for raw material and cement; according to Hardgrove for coal and according to Bond for ores
• KHD crushability and abrasion tests, etc.

Test facilities

Laboratory up to semi-industrial test facilities at KHD Humboldt Wedag´s test center allow for realistic tests with materials related to the cement production process like raw materials, clinker, slag, petcoke etc.
