Pilot Plant

allmineral can prove its process through the testing of your material in our pilot plants. From density separation to magnetic separation, we have you covered.

At allmineral, 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.

Our test program includes

  • Sampling of the raw feed to establish the input gradation.
  • 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.
  • Documenting the results.
  • A detailed information report and test conclusion.

The allmineral test facility helps to provide comprehensive answers to vital project investment questions. It’s all about you – the allmineral customer!

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, allmineral is prepared to accept larger samples for a more extensive test program. Please contact allmineral 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)
