An impact material processing device has a central impact mechanism arranged to rotate about a rotation axis and at least one stator extending circumferentially about the impact mechanism. Each stator has one or more openings through which material impacted by the impact mechanism can pass. A housing extends about the stator and between an upper plate and a base plate. Each stator is located within the housing and can be moved between a first position and a bypass position. In the first position a lower edge of one or more stator is on the base plate and an upper edge extends to at least an inside surface of the upper plate. In the bypass position the stator is moved to where the lower edge of the stator is lifted from the base plate to form a gap through which material entering the device can flow radially beyond the stator.

The housing assembly also comprises an inner ring having at least one inner ring housing groove and at least one inner ring pitman groove and being disposed on the interior side of the housing assembly, and an outer ring having at least one outer ring groove and being disposed on the exterior side of the housing assembly. The housing assembly is disposed around the eccentric shaft. A method for removably housing a bearing assembly on a rock crusher.

A tilted kitchen waste disposer, including a housing, a kitchen waste bin which is arranged on the housing, wherein the kitchen waste bin is provided with a stirring chamber. The housing is provided with an upper end opening that connects with the stirring chamber and an upper cover body which is arranged on the upper end opening, and on one side of the housing is provided with a supporting portion that incline from the side of the housing to the bottom of the housing. When the supporting portion contacts with the horizontal plane, the upper end face of the housing forms a certain angle with the horizontal plane. In the present invention, by setting the supporting portion that inclines from the side of the housing to the bottom of the housing, the upper end face of the housing forms a certain angle with the horizontal plane when the supporting portion contacts with the horizontal plane, which can facilitate users to observe the internal condition of the kitchen waste bin from the upper end face of the housing and put kitchen waste therein. Thus, the users do not have to observe the internal condition of the kitchen waste bin directly above the kitchen waste bin, which enhances experience of users.

A pulverizer may have such features as a drum having a top and bottom, a rotating shaft extending vertically in the drum having radially extending arms that create flow currents within the pulverizer to size reduce a material, and a dust collection system coupled to the outlet for extracting air and dust from the size reduced material. The pulverizer may have an ability to detect wrapping as well as possibly deter wrapping. A processor may also adjust the speed of rotation of the arms within the pulverizer and/or the speed of feed of input for various considerations. In fact the rotation direction may be reversed for at least brief periods of time in an effort to remove wrapped material. Vibration may also be sensed and efforts to prevent damage may be instigated by a processor.
