A impact crusher with dual rotor and an upper rotor assembly (50) for the impact crusher are disclosed herein. The upper rotor (30) of the impact crusher comprises two discs on top of each other. The upper rotor (30) comprises a plurality of hammers (40) pointing down, to the outer perimeter of the lower rotor (20) discharging the material to be crushed at high speed. Each hammer (40) has a support shaft (41) that extends vertically between the first disc (31) and the second disc (32). The distance between the first disc (31) and the second disc (32) provides torsional structure to the connection between the hammer and the upper rotor (30). The upper rotor (30) is configured to be tilted into a service position, wherein the service position is tilted between 90 degrees and 180 degrees from a crushing position.

The various embodiments disclosed and pictured illustrate a hammer for comminuting various materials. The embodiments pictured and described herein are primarily for use with a rotatable hammermill assembly. The hammer includes a connector end having a rod hole therein, a contact end for delivery of energy to the material to be comminuted, and a neck affixing the connector end to the contact end. The neck is formed with at least one neck recess therein. In other embodiments, one or more shoulders are positioned around the periphery of the rod hole for added strength. In still other embodiments, the contact end is configured with more than one contact surface.

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.

A mulching apparatus including: a housing including a front opening and an inner wall; a rotor mounted in the front opening of the housing adjacent to the inner wall; and a liner mounting system for mounting a replaceable wear liner between the rotor and the inner wall, the liner mounting system including: an upper mounting provided at an upper edge of the inner wall, the upper mounting configured to releasably connect with the wear liner; and a lower mounting provided at a lower edge of the inner wall, the lower mounting configured to support the wear liner against the upper mounting and secure the wear liner to the inner wall.

An autogenous impact mill (10) is operative to size reduce friable material particles processed through operation of the mill. At least one impeller (58) rotatable within an interior area (44) of a housing (12) of the mill is operative to produce one or more air jets. The air jets are operative to suspend material particles using the Coanda Effect. Other particles moved by the air jets bounce off ricochet bars (74) and impact suspended particles so as to break and reduce the particles to a suitable size to pass through a screen (110) to an outlet opening (42).

The present disclosure relates to a vertical shaft impact crusher comprising a rotor having a rotor protection layer which consists of particles of objects to be crushed. The rotor includes at least: a rotor upper plate comprising a rotor upper plate hole, which is an inlet for the object for crushing which is inserted into the rotor; a rotor lower plate disposed to be separated from the lower portion of the rotor upper plate; a rotor upper plate; a rotor side wall disposed between the rotor upper plate and the rotor lower plate and coupled to the rotor upper plate and the rotor lower plate, the rotor side wall being disposed at a position spaced from the rotation center of the rotor; and a circular hole which is formed on the rotor side wall and is an outlet for the object for crushing accelerated by the rotor to come out of the rotor.

Methods for manufacturing improved free-swinging hammermill hammer configurations are disclosed and described and include hammers of a lightweight and efficient design. The improved hammers can be arranged in clusters. The free-swinging hammermill hammer configurations are for comminution of materials such as grain and refuse. The hammer configurations of the present disclosure are adaptable to most hammer mill or grinders having free-swinging systems. The improved configurations improve installing, removing, and cleaning hammer components within the hammermill. Additionally, the hammer configurations of the present disclosure improve the overall efficiency of the hammermill during operation.

An apparatus for tearing meat is disclosed. The apparatus includes a gravity-fed hopper including at least one sidewall that forms a first opening configured to receive meat articles and a second opening configured to discharge torn meat articles. The apparatus includes a rotatable spindle element positioned at least partially within the hopper and downstream of the first opening. The rotatable spindle element includes a shaft having a longitudinal axis and a plurality of teeth coupled to the shaft, the teeth being spaced apart from one another. The apparatus includes a plurality of rods, which extend from the sidewall spaced apart from one another and which are interlaced with the plurality of teeth, and a motor coupled to the rotatable spindle element configured to rotate the rotatable spindle element to cause at least some of the plurality of teeth to rotate and pass between two different rods.

A cuttings processing unit may include a conveyor interface configured to interface with a mud cleaning complex to receive drill cuttings. The cuttings processing unit may further include a breaker mill module operably positioned to receive the cuttings via the conveyor interface, a cuttings tank module operably positioned beneath the breaker mill module, and a pump module operably positioned beneath the cuttings tank module. The breaker mill module may be configured to grind the cuttings into a finer composition. The cuttings tank module may be configured to agitate the finer composition and create a slurry. The pump module may be configured to move the slurry.

A mill includes a housing with a first end portion, a second end portion, and a lateral area disposed therebetween. The housing includes a raw material inlet, an air inlet, a recirculated material inlet, and a material outlet. An impeller is supported by the housing and includes a shaft disposed along the longitudinal axis of the housing, with a plurality of curved blades.
