There is much ongoing debate and concern regarding access to COVID-19 vaccines and roll-out gaps in low-income and middle-income countries compared with high-income countries. African countries, many of which are low-income, also face issues with reciprocation after vaccine trials are done among their populations and the need to devolve vaccine manufacturing locally.
P150 High-Pressure Grinding Roll . The FL P150 High-Pressure Grinding Roll (HPGR) sizing machine is used for all initial HPGR lab-scale test work. The pilot-scale crusher is designed to process ore in the identical manner of an industrial unit, as it employs the exact same breaking mechanism. We have determined that the P150 HPGR is the ...
