PURPOSE:To provide a titled plant which reduces the costs of dehydration and installations, by the constitution wherein fillers are dehydrated to the extent of causing substantially no troubles with a centrifugal dehydrator and are then transported while mixing with pulverulent bodies of base materials by using a line feed mixer. CONSTITUTION:In a mixing plant 1 for impregnating materials of pulverulent bodies, gravel 5 drawn from rivers is dehydrated to cause substantially no troubles with a centrifugal dehydrator 18, whereafter the gravel is fed into a hopper 6 with a bucket conveyor 25. In a mixing unit 2, sand is fed from a filler hopper 6 and cement which is a base material is fed from a cement silo 4, respectively, and both are fed by every prescribed rate with a feeder 9 into a line feed mixer 10 serving both as a mixer and a conveyor through dischage ports 7, 8. The pulverulent body mixture obtained here is transferred through the supply port 28 of the mixer 10 to a screw conveyor 29, and is further supplied through the hopper 32 of a pneumatic transport device 26 for the pulverulent bodies to an impregnating pipe 36 for the purpose of land improvement. |
