Low profile load out lump breaker

A system for crushing of dry powder containing lumps during dry powder load out, the system comprising:

• a load out chute operably associated with a material storage bin configured to download dry powder material from the bin,
• a screen hopper configured for screening lumps of dry powder material above a threshold size from downloaded dry powder materials during the load out process,
• the load out chute comprising an upper portion positioned above the screen hopper and a lower portion positioned below the screen hopper and further positioned to transfer the downloaded dry powder material to a waiting receptacle during load out;
• a mill configured for breaking up the lumps of dry powder material above the threshold size aggregated from the dry powder material accumulated above the screen hopper;
• a mill diversion chute operably associated with the screen hopper through which the lumps of dry powder material above the threshold size aggregated from the dry powder material accumulated above the screen hopper may be diverted for break up by the mill;
• a discharge chute for transport of dry powder material to be discharged once the lumps of dry powder material above the threshold size aggregated from the dry powder material have been broken up by the mill;
• a load out isolation gate configured to open and close, operably associated with the load out chute and configured to close upon command to stop dry powder material flow from the load out chute when signaled that the screen hopper has become or is becoming plugged with lumps;
• and a mill isolation gate configured to open and close and configured to open upon command to feed the lumps of dry powder material to the mill for breaking up the lumps of dry powder material in a synchronized manner with the load out isolation gate, the load out isolation gate closing in association with the mill isolation gate opening;
• and,
• a controller programmed to synchronize operations between load out and lump break up operations, including operably synchronized opening and closing of the load out isolation gate with the mill isolation gate upon automated signaling that the screen hopper has become or is becoming plugged with the lumps of dry powder material above the threshold size aggregated from the dry powder material and prevents the mill isolation gate from being opened for crushing of dry powder containing said lumps by the mill unless the load out gate is closed.
