PROBLEM TO BE SOLVED: To provide a loader hopper capable of easily and sufficiently performing separation of powder and dust and mixture of powder, while always introducing powder and granular body of fixed quantity by a suction of a suction type pneumatic source, without being mixed with dust and water in the atmosphere. SOLUTION: In this loader hopper, a hopper body 12 is connected with a powder and granular body supply pipe, a primary side sub-suction pipe 34 and a secondary side sub-suction pipe 35. The primary side sub-suction pipe 34 and the secondary side sub-suction pipe 35 are connected with a main suction pipe 33 connected with a suction type blower 32. Powder and granular body transported by pneumatics within the loader hopper 12 by an operation of the suction type blower 32 is agitated and mixed within the loader hopper 12 by operating an adjusting valve 37, and thereby mixed powder falls to a lower side hopper part 17 and dust is delivered to the primary side sub-suction pipe 34. As a result, powder and dust are excellently separated and powder is uniformly mixed.
