The utility model discloses a kind of screening devices before wet corn secondary crushing, by primary mill lower pump, primary
embryo cyclone, pressure curved screen, secondary mill upper tank, secondary mill upper tank liquid level meter, secondary unloading valve, secondary crushing mill, secondary mill lower tank, secondary mill lower tank water adding valve, secondary mill lower tank liquid level meter, secondary mill lower pump and control module composition, in wet corn crushing process, traditional process is as follows: corn dilute
slurry that primary
embryo cyclone underflow comes out directly enters secondary crushing mill, since corn dilute
slurry concentration is low, secondary crushing mill load is big,
processing efficiency is low;The utility model increases pressure curved screen screening on primary
embryo cyclone underflow
discharge pipeline, secondary mill upper tank buffering, additionally increases liquid level control
automatic control module, solve the problem that secondary crushing mill load is big,
processing efficiency is low, also reduce the labor intensity of operator simultaneously.
