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 slag crusher includes: a porous member screen; a spreader that is reciprocated in a predetermined direction along a top surface of the screen and crushes the slag accumulated on the screen; and a guide rod having an axis line along the predetermined direction, is connected to the spreader, and restricts a moving direction of the spreader, the guide rod has a spreader-side member connected to the spreader and a shaft member connected to the spreader-side member, the spreader-side member and the shaft member are connected by butt welding in the axis line direction, and the spreader-side member and the shaft member have the same shape of cross sections orthogonal to the axis line direction at a butt welding position.

The present invention relates to an equipment in the field of hygiene article manufacturing, in particular to a hygiene article recycling unit for disintegrating and separating hygiene articles allowing to separate raw materials at a purity allowing to directly use it in the manufacturing process of the hygiene articles. The recycling unit comprised several devices as sub-units. The present invention further relates to a process for operating such an equipment.

The present disclosure relates to a waste management system comprising a first waste bin having a first camera operatively configured to a controller. Images of waste captured by the first camera are analyzed by the controller to ensure that the waste is a plastic waste. Further, a categorization mechanism executing at the controller classifies the plastic waste in at least one of a plastic category using a machine learning mechanism. The system comprises a motor for shredding the plastic waste and a sieve for collecting the shredded plastic waste. Containers attached at an end of the sieve receive and store the shredded plastic waste. The system comprises a second waste bin having a second camera for capturing images of the general/wet waste and categorizing the images to alert user about potential food waste. Categorized wet waste is collected in the second bin.

A microwave applicator box for breakdown of medical waste materials is provided, including: an interior defined by at least one wall; a plurality of inclined grates in an alternating arrangement, including: a first grate extending from a first direction, and a second grate extending from a second direction and underlapping the first grate; vibration devices connected to the grates by arms; wherein the area above the first grate is defined as a Zone A and wherein the area below the first grate and above the second grate is defined as a Zone B; wherein a first waveguide is connected to an opening in the wall in the area of the Zone A; wherein a second waveguide is connected to an opening in the wall in the area of the Zone B; and wherein the interior of the waveguides is in communication with the interior of the microwave applicator box.

A shredder includes a shredder box having first and second opposite end walls, and first and second opposite side walls that extend between the first and second end walls. The shredder further includes a shredder rotor positioned within an interior of the shredder box, an access door that is pivotally moveable, and a control system for monitoring various parameters to operate the shredder. A side access region is defined between the first and second end walls when the access door is in the open position. The side access region provides access to the shredder rotor and includes an open region defined between the first and second end walls at the second side of the shredder. The open region has an open top which is free of obstructions extending between the first and second end walls.

The invention relates to a continuous dry granulation method and non-invasive monitoring and control of the dry granulation method. The invention further describes a dry granulation system and uses thereof. In particular, the non-invasive monitoring methods employ a sound, force, strain, vibration and/or acceleration sensor in order to determine the mechanical strength of a compacted material during a dry granulation process. Further, the compaction parameters of the compacting unit of the granulation process may be controlled to maintain a target mechanical strength of the compacted material.

A shredder includes a shredder box having first and second opposite end walls, and first and second opposite side walls that extend between the first and second end walls. The shredder further includes a shredder rotor positioned within an interior of the shredder box, an access door that is pivotally moveable, and a control system for monitoring various parameters to operate the shredder. A side access region is defined between the first and second end walls when the access door is in the open position. The side access region provides access to the shredder rotor and includes an open region defined between the first and second end walls at the second side of the shredder. The open region has an open top which is free of obstructions extending between the first and second end walls.

Disclosed is a pruning and sieving apparatus, which resolves time-consuming and laborious problems in the existing pruning method of flower plants. The pruning and sieving apparatus includes a hollow body, including two relatively disposed open axial ends; an interior pruning lining attached inside the hollow body, where the interior pruning lining includes a plurality of sidewall pruning holes arranged in a distributed manner; a sieving screen, where the sieving screen includes a plurality of sieving holes arranged in a distributed manner, and is disposed in the interior pruning lining to divide the internal space of the interior pruning lining into a pruning chamber and a collection chamber; and two end caps disposed on the two open axial ends.

Described are various embodiments of a continuous sluicing device, and method of manufacturing same. One aspect relates to a rotatable sluicing device comprising an inner trommel and an outer separating cylinder, wherein the outer separating cylinder comprises a rifled baffling portion disposed on an inner surface thereof. The rifled baffling portion comprises a helical collection riffle and one or more spiral fighting portions disposed near and substantially parallel to an edge of the helical collection riffle. Rotation of the inner trommel portion and outer separating cylinder urges lower density substrates to discharge from respective discharge ends thereof, and urges heavy particulate material in the helical collection riffle to move upstream for collection in a collection reservoir.
