In this tower at the "E. Blum" Sand Works the various types of sand are washed, graded and distributed to the various loading points on the Loading Bridge, # 61123. Using the Sand Silo and Sand Transport, # 61125, a conveyor belt can be added direct from the ground to the grading room. The tower stands on a strong base and has a covered ramp. The partially weathered model can also be used as a separate building on its own.
