Material Testing

HAZEMAG Test Plant

We are committed to providing a level of partnership and customer service that is second to none. This is your test center: a place to help create a solid foundation of valuable information for equipment consideration, selection and future investment. We offer a comprehensive test plan, tailored specifically to your process goals and project needs. Important raw material characteristics will be established through a series of tests which include crushing, screening, material analysis and observation. 

The HAZEMAG test plant uses three full-scale production impactor models: HSI-0806, HSI-0604 and HTI-0805. With an extensive history of material testing, backed by +75 years of application experience, the HAZEMAG test center is your facility to help establish valuable information specific to your project goals, material processing needs and the potential use of the Andreas Impactor.

  • Raw feed moisture level testing. 
  • A test plan (crushing tests) specific to your project goals. 
  • Sampling of each test to establish the output gradation. 
  • Chemical testing to establish the Silica and Magnesium Oxide levels. 
  • Los Angeles (L.A.) testing to establish the hardness of the material. 
  • Product analysis to establish crushing (breaking) patterns.

Test Sample

What is Needed?

Feed materials (samples) for crushing tests must be provided by the customer. For the normal test program, two (2) to four (4) 55-gallon drums of applicable material will be required. As the project may warrant, HAZEMAG is prepared to accept larger samples for a more extensive test program. Please contact HAZEMAG to discuss the amount of test material that is needed for your specific project needs.

The test sample should be identified with the following information:

  • Company Name
  • Contact Person
  • Phone Number
  • Test Material (Example: Limestone)
  • Identification (Example: Hard Limestone)
