The present invention provides a particle packing apparatus which can pack uniformly particles of catalyst, etc. without breaking the particles. The particle packing apparatus for packing particles into a vessel, comprises: a base held at a fixed position with respect to the vessel; a distributor which is rotational symmetrical to a central axis extended vertically and distributes the particles; a bearing fixed to the base and holding the distributor rotatably; a particle supplying unit fixed to the base, being rotational symmetrical to the central axis, having a bottom opening being smaller than an inner diameter of the bearing and supplying the particles to the distributor through the bottom opening; and a motor rotating the distributor.

A distribution head of a gravimetric loading system for spreadable bulk materials with a rotatably driven spreader plate, which is composed of a bottom side base plate, which is connected in the central region with the one end of a drive shaft and on which a number of blades evenly distributed on the circumference and with their blade edges approximately in a radially outward direction is arranged. The blade edges of blades are interrupted in the direction of the central axial drive shaft and thus a ring channel extending in the axial direction and free from structures is formed, which channel forms an additional filling and receiving space for the bulk material to be distributed.

A distribution head (20) of a gravimetric loading system for spreadable bulk materials with a rotatably driven spreader plate (40), which is composed of a bottom side base plate (53), which is connected in the central region with the one end of a drive shaft (21) and on which a number of blades (33-35) evenly distributed on the circumference and with their blade edges (52) approximately in a radially outward direction is arranged, wherein the blade edges (52) of blades (33-35) are interrupted in the direction of the central axial drive shaft (21) and thus a ring channel (43) extending in the axial direction and free from structures is formed, which channel forms an additional filling and receiving space for the bulk material to be distributed.
