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 friction driven beltless grain spreader system is presented that includes a spreader cone having a pulley and a grain deflector configured to disperse the flow of grain. A motor having a driven wheel and an idler wheel are pivotally connected to the spreader cone in operative engagement with the pulley such that the idler wheel is positioned between the driven wheel and the pulley. A tension member applies a force that pulls the driven wheel and intermediary wheel into the pulley. As the motor rotates the driven wheel rotates the idler wheel which rotates the pulley. When forces spike, such as when the motor is turned on or a heavy flow of grain hits the system, one or more of the driven wheel, intermediary wheel and/or pulley slip with respect to the other wheels thereby preventing breakage of the system.

A grain spreader for a grain bin is provided with an electric motor having a domed or conical cap. The inclination of the cap is preferably 45. The inclination of the cap eliminates grain splattering and minimizes wear on the cap. The cap includes an internal hub with an axial cavity. A bearing is mounted within the cavity to rotatably support an upper end of the motor drive shaft.

The present invention is a spreader device used to fill a container or silo with grain that comprises a shaped body including a primary opening with a removable cover and several angled, peripheral openings located a distance from the primary opening. The spreader functions by allowing grain to pass through its primary opening to form a single flow column and grain pile and then having the primary opening closed via the cover to direct grain to the one or more peripheral openings, thereby creating multiple flow columns and grain piles that are located radially away from the primary flow column and grain pile.
