ALS conducts the majority of comminution tests required for plant design. The term "comminution" originates from Latin and translates roughly in English "to make particles small", which is one of the first processing duties of most plants on the feed ore. The energy to do so is also one of the largest costs of any industrial plant, and so comminution tests were established to predict those energy requirements and associated costs to power the crushers and mills.
ALS has an entirely dedicated technician team and facility for comminution. We participate routinely in industry round robin tests to ensure accuracy and precision of our comminution results. In order to provide statistical certainty for engineering design modelling, comminution tests are designed as a fixed prescribed procedure, leading to the assumption that all laboratories results must be identical. Incorrect. There are critical maintenance and monitoring tasks required for the apparatus and media, preparation of standards, and simply fine nuances and ergonomics of each test that require long experience to achieve. Any oversight on these items will lead to biased results.
Keep in mind the mass may vary depending on the particle size distribution in order to contain the above particle sets, but some rough guidelines are as follows:
Yes. ALS has a duplicated comminution room (Bond and JK Drop Tester) to treat fibrous and radioactive samples. Surcharges do apply, however, to cover safety equipment, monitoring and decontamination.
ALS is a quarantine approved premises and treats many samples of oversea origin. Strict regulatory requirements are in needed around packaging and paperwork, however. ALS can advise you on these requirements.
