摘要： PROBLEM TO BE SOLVED: To provide a ready mixed concrete manufacturing plant provided with a belt cleaner being versatile for removing adherents on the belt of an inclined belt conveyer. SOLUTION: In a ready mixed concrete manufacturing plant wherein a mixing room, a metering room, a storing room and a material receiving room are stacked up in a multilevel hierarchy and a distributing shoots 3 for distributing materials into the storing room at a lower level is arranged in the material receiving room and the apex part of the inclined belt conveyer 5 for carrying aggregates is made to face to the distributing shoot 3, an air jetting nozzle 10 is arranged at an appropriate position toward the belt 5 on the returning path side in the neighborhood of a head pulley 6 and compressed air jetted from the air jetting nozzle 10 is jetted toward the apex direction of the head pulley 6 to blow away adherents on the belt to the front of the head pulley 6 and to make them fall into the material receiving shoot 8.

摘要： PURPOSE: To prevent inclusion of sludge by lowering a clean water recovering part having a float part into water when sludge separates owing to gravity settling, and recovering the clean water near the water surface.
CONSTITUTION: The agitation of a sludge water tank 16 which stores sludge water made by separating gravel and sand from water contg. ready mixed concrete is stopped, and when sludge separates, a clean water recovery part provided with a float part 32, a water receiving part 30 and a flexible pipe 31 is lowered into the water. The clean water recovery part lowered into the water floats near the water surface owing to the buoyancy of the float part 3, and the clean water flows into the part 30 and is received into a clean water tank 22 through a flexible pipe 31.
