Comminution Plant ...... Through January 31, 2021, PLAN has spent over $500,000 on building a comminution plant. This plant was designed to produce fine powders from natural pozzolan mined from the Z1 Natural Pozzolan Quarry as well as being able to pulverize post-consumer glass down to a fine powder...... PLAN is developing a supplementary cementing material, PozGlass SCM, which is a combination of Z1 Natural Pozzolan and finely ground postconsumer glass..... The comminution plant consists of a jaw crusher, a hammer mill, a ball mill, and an air classifier which separates particles by their weight. Ancillary equipment includes conveyors, fans, dust collection systems, etc...... As a general rule of thumb, natural pozzolans are more reactive as a component of cement when the particles are smaller. Cement industry users expect particles to be less than 45 microns and the American Society of Tests and Measures (ASTM) developed standard specifications for ground glass pozzolan in 2020..... These standards are identified as ASTM C1866/C1866M-20. These specific standards require that 95% of the ground glass pozzolan is smaller than 45 microns.... In the Fall of 2019, a regional toll processing comminution plant in southern Alberta closed. PLAN purchased some of its equipment and filled a market gap to produce fine powders with the commissioning of its comminution plant in Spallumcheen, BC in late August 2020..... PLAN invoiced its first customer for comminution toll processing in October 2020. PLAN currently has a backlog of orders for third party customers and has ordered larger equipment to increase the throughput of the plant. The new equipment is expected to be commissioned in March 2021.
