An apparatus and a method are for separating a plastic-based insulation material from a concrete-based constructional element, to which the insulation material is attached. The apparatus has at least one fluid-jetting device which is in fluid communication with a pressure-generating device to produce a fluid jet with a pressure sufficient to release the insulation material from the constructional element. The apparatus is configured to allow relative motion between the fluid-jetting device and the constructional element.

Featured are a two-stage grinder, an apparatus embodying same and methods related thereto. Such a medical waste grinder includes a first stage and a second stage. The first stage includes spring loaded cutter stacks mounted on two adjacent shafts between two edge plates, each of the cutter stacks including cutters arranged in a helix to create space, each cutter including a number of teeth per blade and including a major diameter and a minor diameter, each cutter turning opposite a fixed counter knife enabling a pinching action against the teeth of the cutter. The second stage includes spring loaded cutter stacks.

The system and method requiring a diverter plate for an in-line mill. The plate for use with the in-line mill includes an aperture for passage of particulate laden fluid therethrough and a plurality of tabs such that the fluid and the particulate entrained thereon is deflected at a variety of axial angles. The diverter plate thus provides a reliable method such that the milling process and component wear resistance is made more efficient thereby.

A small-form-factor high-security destruction machine for optical media has a weight empty of about 16.3 lbs and holds about 5 lbs of residue.

Method for processing organic material is disclosed which breaks down the inedible components of fruit and vegetables (core, skin, pips, pithy material) into an edible substance with a cream-like consistency. The method includes pressurizing the material and forcing it through a passage having a number of end-to-end sections which are at right angles to one another. The material as it emerges from each section impacts on the impact surface at the end of each section and changes direction and flows into the next section of the series.

The invention shows and describes a vibration mill for at least two grinding beakers performing vibrations in the horizontal position, with at least one multi-part pendulum drive, wherein the pendulum drive has at least one eccentric shaft mounted to rotate about a vertical eccentric axis, and at least two rockers each mounted so as to be capable of vibrating about a vertical vibration axis and connected by means of couplers to the eccentric shaft, said rockers holding the grinding beakers. The pendulum drive further has a motor unit coupled to the eccentric shaft as a drive for the eccentric shaft and optionally further components, wherein a rotary movement of the eccentric shaft via the couplers can be converted into a vibrating movement of the rockers. According to the invention, the centre of gravity of the pendulum drive in a horizontal centre of gravity plane is substantially equidistant from both vibration axes.

A grinding chamber of a grinding device for vegetal products suitable to form beverages includes, in its interior, a pair of grinders axially overlapping each other, one of which is rotatable with respect to the other which is kept stationary, a grinder support at least for the rotatable grinder, a motor member connected to the grinder support for setting the rotatable grinder in rotation. The grinding chamber is formed by a first bottom wall, perpendicular to the axis of rotation of the rotatable grinder, adjacent and below the support thereof, and at least a second cylindrical wall, connected axially to the first wall at the peripheral boundary thereof. The grinding chamber also includes a first opening for introducing the product to be ground and with a second opening for discharging the ground product. A labyrinth is provided between the peripheral boundary of the first wall and the grinder support.

A method for manufacturing a processed asphalt suspension is provided. The method includes dry grinding shingle waste material to a particle size of less than 1 cm, forming ground recycled shingle material, introducing virgin asphalt into a heated slurry tank and mixing the ground recycled shingle material with the virgin asphalt in the heated slurry tank, forming a mixed asphalt slurry, introducing the mixed asphalt slurry into a wet grinding machine, and recovering a processed asphalt suspension comprising particles having a size no greater than about 200 microns. Roofing and paving products manufactured from the processed asphalt suspension are also provided.

A system for neutralizing prescription drugs, narcotics and other harmful substances, including a staging area for an initial collection and sorting of prescription drugs, narcotics and other harmful substances to be neutralized, a containment chamber assembly operatively connected to the staging area for granulating the prescription drugs, narcotics and other harmful substances, a waste grinder/vacuum assembly operatively connected to the containment chamber for destroying any packaging that contained the prescription drugs, narcotics and other harmful substances, and a neutralizing assembly operatively connected to the containment chamber for neutralizing the granulated prescription drugs, narcotics and other harmful substances, with a neutralizing agent.
