Vaporizers are provided. A representative vaporizer includes a power source; a heating element that is electrically coupled to the power source; multiple chambers that are coupled to the heating element and are configured to vaporize a substance that is placed within the multiple chambers; an inner tube that is coupled to the multiple chambers and is configured to allow the vaporized substance to exit therefrom; and a housing that houses the power source, heating element, inner tube, and multiple chambers.

A compound blade assembly for recycling machines that process random sized waste metals into uniform reusable material. A rotating processing blade and a fixed registerable bed blade each have interchangeable blade teeth sets of multiple blade edge surfaces for interengaging target waste material at multiple shear points by registerable intermeshing in a linear progressive repetitive process.

A chopping blade for cutting against a shear bar has a main body made of hardened steel. The blade body is formed with at least one cutting-edge region, a fastening region for fastening the blade to a carrier and in each case a transition region between the cutting-edge region and the fastening region. The main body bears a hard material coating in the cutting-edge region. The hardness of the main body is uniform throughout over all regions. A chopping drum carries a multiplicity of these chopping blades on its periphery and, upon rotation of the chopping drum, the chopping blades cut material upon running up against a stationary shear bar.

The present invention concerns a rotary cutting tool (1) with a cylindrical supporting spindle (2) and several individual blades (3) with essentially radial cutting edges, helically ground and set at regular intervals on the outer surface of the spindle, each blade (3) having a rectilinear base (4) which inserts into a slot (5) of the same shape as said base, each individual blade (3) being mechanically fixed to the spindle (2), characterized in that it also comprises two covers (8, 9) fixed to the respective bases (8, 9) of the spindle (2) so as to reinforce the fixing of the blades (3).

The present invention relates to a counter-blade, in particular, for a wood chipper, for producing wood chips, comprising at least one cutting edge made of a hard material, and a support surface leading to the cutting edge. According to the present invention, the cutting edge is made up of a plurality of hard material elements that are arranged next to one another along the cutting edge on a main member. This results in a counter-blade having a long service life.

A material shredder is provided for shredding recyclable materials. The shredder includes a rotor with multiple cutting blades arranged around its outer surface. These blades have cutting edges that form a cutting circumference. The rotor is enclosed by a housing, creating a cutting chamber between the rotor and stator. Inside this chamber, the cutting blades interact with at least one counter blade mounted on the inner surface of the stator, spaced to form a cutting gap. The stator also includes at least one outlet with a screen that helps define the cutting chamber. The shredder further includes a grinding device with an abrasive holder, located outside the cutting circumference. Both the abrasive and the screen can be moved to adjust their distance from the cutting circumference. The invention also includes a shredding plant with the shredder and a method for maintaining the shredder.

A strand pelletizer for pelletizing strands such as strands of plastic material into pellets, having a cutting mechanism which has a rotationally drivable cutting rotor and a counter-knife cooperating therewith, wherein a cutting gap is formed between a cutting edge of the counter-knife and rotor tooth tips of the cutting rotor. A cutting gap adjustment apparatus with a cutting gap adjustment drive is provided for adjusting the gap dimension of the cutting gap during operation of the cutting mechanism.

An electric meat shredding apparatus includes a first shredding assembly and a second shredding assembly, the first shredding assembly includes a first shredding member, the second shredding assembly includes a second shredding member, the first shredding member and the second shredding member cooperatively define a first chamber; the first shredding member is provided with a plurality of first spikes extending toward the second shredding member, and the second shredding member is provided with a plurality of second spikes extending toward the first shredding member; in the first chamber, the plurality of first spikes are staggered with the plurality of second spikes; the second shredding member further includes a drive member, the drive member is drivably connected to the second shredding member to drive the second shredding member to rotate relative to the first shredding member.

A shredder for shredding material, the shredder comprising a housing supporting two rotating shafts arranged parallel to each other, each shaft having a plurality of overlapping and offset transverse shredding blades along the shafts able to rotate on the shafts in a complementary fashion to shred the material thereinbetween, the shredding blade on each shaft nearest to the housing being an outermost shredding blade and having a gap between of the outermost shredding blade and the housing, wherein the gap at least partly comprises a V-shape.
