APPARATUS FOR CRUSHING/REWASHING/TREATING GRAVEL, CRUSHED STONE, CRUSHED SAND, SAND, AND WASTE CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for crushing/rewashing/treating gravel, crushed stone, crushed sand, sand, and waste concrete which is excellent in durability and operability, is used for various purposes, can process pebbles into aggregate, and can produce high quality concrete aggregate efficiently. ;SOLUTION: A cylindrical barrel part 2 having an inlet 9 for gravel and others and a washing water supply pipe 13 is installed on a base 1, and a cantilever rotary main shaft 4 in which agitation blades 3 are mounted on the periphery is installed at the center of the barrel part 2. A rotary subordinate shaft 16 is installed on the same shaft center with a main shaft 4, and a pressure lid 5 is attached to the shaft 16 to be engaged with the discharge opening 10 of the barrel part 2. Ultra-hard chips 18 are set on the inside of the discharge opening 10 and the fringe of the lid 5. A slide base 12 for supporting the shaft 16 and a stopper 20 for fitting the base 12 in a proper place are installed on the base 1. A hydraulic cylinder 7 is connected to the slide base 12, which is connected with a hydraulic unit 8. The actuation of the cylinder 7 and the supply of washing water are controlled corresponding to the pressure in the barrel part 2.;COPYRIGHT: (C)1999,JPO
