A vertical shaft impact crusher feed hopper distribution device arranged for feeding material to be crushed to a rotor of a vertical shaft impact crusher. The feed hopper distribution device is arranged to be mounted in a feed hopper that feeds material to the rotor and includes a supply channel that forwards material from an inlet opening arranged adjacent to an upper end of the supply channel to a hopper bottom opening arranged in a bottom of the feed hopper and communicating with the rotor. The supply channel has a cross-section that widens along at least a portion of the distance from the upper end to a lower end of the supply channel.

A device and a method for processing feed material that has a housing, a material supply channel and a material discharge. The housing is axially divided into a first processing zone in which a rotor rotating around an axis is situated, and a second processing zone which adjoins the first processing zone in the flow direction of the feed material. In order to perform different processing procedures in one device the feed material is subject to a process gas by arranging a hollow body in the housing, coaxially to the axis for the formation of the second processing zone, which outer circumference is radially situated opposite the inner circumference of the housing, and which features at least one port at the end that is facing the rotor. A process gas, which can be fed to the feed material through at least one port, is applied to the hollow body.

A pulverizer has arms connected to a vertically oriented rotating shaft at hubs. The arms are angled relative to radians extending from the shaft to be canted or offset. Pads can be oversized relative to the arms while being one of coplanar with the arms or recessed while possibly also having their radially inward face(s) angled to assist in resisting catching material thereon. A mechanical fuse connection can assist in connecting arms to the hub to prevent dangerous situations as well.
