A blade head for granulating strands of material comprises a blade carrier and at least one granulating blade fastened thereto. The respective granulating blade is fastened to a positioning component which bears against the blade carrier for the rough positioning of the granulating blade. For fine positioning purposes, at least one adjusting element bears against the respective granulating blade. The blade head permits simple, user-friendly and precise assembly and setting of the respective granulating blade.

An accumulation device that is operable in a feeding arrangement of a granulator, for accumulating flat material to be granulated, includes a first guiding device and a second guiding device. The accumulation device further includes a rotational shaft arranged to connect the accumulation device to the feeding arrangement. The first and the second guiding device are fixedly arranged in relation to each other so that when the accumulation device is rotated around its rotational shaft, the first guiding device as well as the second guiding device is rotated around the rotational shaft. A feeding arrangement and a granulator including such an accumulator device are also provided.

Disclosed is an accumulation device (150) operable in a feeding arrangement (110) of a granulator, for accumulating substantially flat material to be granulated. The accumulation device (150) comprises a first guiding device (152) and a second guiding device (154). The accumulation device (150) further comprises a rotational shaft (156) arranged to connect the accumulation device (150) to the feeding arrangement (110). The first and the second guiding device (152, 154) are fixedly arranged in relation to each other so that when the accumulation device (150) is rotated around its rotational shaft, the first guiding device (152) as well as the second guiding device (154) is rotated around the rotational shaft (156). Disclosed are further a feeding arrangement (110) and a granulator comprising such an accumulator device (150).

A modular shredder and grinder apparatus includes a grinder assembly that has a grinder shaft assembly. The grinder assembly has a grinder opening and a shredder assembly movable with respect to the grinder opening to allow access to the grinder shaft assembly. Scrap material is first fed into the shredder assembly so that shredded scrap material is received through the grinder opening and further cut by the grinder shaft assembly.

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.

A device for processing thermoplastic plastic includes a storage container for receiving pieces of plastic particles or a conveying line for conveying the pieces of plastic particles, and a conveying screw following the storage container/the conveying line at a transfer opening. The device also includes an extruder following the conveying screw and an air outlet arranged opposite the transfer opening and directed at this opening. In a method for operating the device, an air stream is aligned with the transfer opening. The strength and/or the direction of the air stream is adjusted or controlled as a function of a load on the extruder.

A plastic granulator apparatus stationary cutting segment includes a segment rail having multiple arcuate spaced teeth. Each tooth of the plurality of arcuate spaced teeth has a tooth surface and is spaced to be complementary to a rotary cutter segments as a rotary cutter is rotated. The segment rail is adapted to be mounted to a granulator housing. The rail segment has a shoulder with a shoulder surface, the shoulder is adjacent to each of a set of arcuate spaced teeth. The shoulder has a shoulder surface height of between 0 and 10 mm, and a stepback distance of between 0 and 2 mm between the shoulder surface and the arcuate tooth surface. The shoulder and the arcuate tooth surface define an angle therebetween of 90 and 130, and the shoulder surface defines an angle between 90 and 130.

A granulator includes a rotary crushing blade for crushing an object to be processed that has been fed into a main body. A stationary granulating blade includes a plurality of small shearing blades below the rotary crushing blade. A movable granulating blade includes a plurality of shearing blades below the rotary crushing blade. The granulator includes an oscillating shaft pivotably supporting the movable granulating blade so as to be oscillatable in directions in which the movable granulating blade moves toward or away from the stationary granulating blade. A driving mechanism is provided for oscillating the oscillating shaft, in which the movable granulating blade is detachably fixed to a movable blade holder and the movable blade holder is detachably fixed to the oscillating shaft.

The invention relates to a granulator having a cutting device which is driven by a drive device and to which a material strand can be supplied, for example by means of a conveying device. The drive device is accommodated in a granulator housing. The cutting device and optionally also the conveying device are arranged in a separate module housing, which is connected in a detachable manner to the granulator housing and can be removed from same. The cutting device and/or the conveying device are connected to the respective drive device via detachable couplings. The cutting device and optionally also the conveying device can be removed from the granulator housing as a unit together with the module housing.

A modular shredder and grinder apparatus includes a grinder assembly that has a grinder shaft assembly. The grinder assembly has a grinder opening and a shredder assembly movable with respect to the grinder opening to allow access to the grinder shaft assembly. Scrap material is first fed into the shredder assembly so that shredded scrap material is received through the grinder opening and further cut by the grinder shaft assembly.
