  • Patent number: 8657220
    Abstract: The invention relates to a rotor (139) for the acceleration of material, in particular a stream of granular or particulate material, with the aid of centrifugal force, with, in particular, the aim of causing the accelerated grains or particles to collide with an impact member at such a velocity that the particles are crushed. The invention provides ways to hinder that particles are pulled from the center space though vortex pulling. The sliding member (143) is provided with a closed space that provides the rotor with a closed center space. When the sliding member (143) are positioned some distance away from the metering member (141), a cover member (134) is positioned above the rotor (139) between the metering member and the sliding member. This enables to design the sliding members shorter and hence cheaper. It enables to place more sliding members on the rotor and hence increase continuous operation time accordingly.

Joints are formed between wear resistant inserts and joints are also formed between wear resistant inserts and the wear component. Bonding material fills the joints to further secure the wear resistant inserts and to prevent crack propagation.

  • Publication number: 20110168824
    Abstract: The invention relates to a rotor (139) for the acceleration of material, in particular a stream of granular or particulate material, with the aid of centrifugal force, with, in particular, the aim of causing the accelerated grains or particles to collide with an impact member at such a velocity that the particles are crushed. The invention provides ways to hinder that particles are pulled from the centre space though vortex pulling. The sliding member (143) is provided with a closed space that provides the rotor with a closed centre space. When the sliding member (143) are positioned some distance away from the metering member (141), a cover member (134) is positioned above the rotor (139) between the metering member and the sliding member. This enables to design the sliding members shorter and hence cheaper. It enables to place more sliding members on the rotor and hence increase continuous operation time accordingly.

  • Patent number: 7967226
    Abstract: A drying mill for powdered or fine-grained material, in particular also suitable for calcining gypsum, employs a housing, in which a feed device for fuel gas, opening into a lower region, a comminuting device and a material inlet, charging the material onto the comminuting device from above, are provided one above the other, a material outlet leading to the outside from an upper region of a working chamber and a return leading downwards to the comminuting device, the comminuting device being a centrifugal disc which rotates in a horizontal plane and interacts with an impact casing arranged on the inside of the housing. A nozzle ring surrounding the centrifugal disc from below is provided for feeding fuel gas into the working chamber. As a result, the calcining process in particular is assisted in an efficient way by utilizing the thermal energy of the hot gas fed into the working chamber by means of the nozzle ring and the dwell time in the working chamber. A corresponding comminuting method is provided.

  • Publication number: 20110024539
    Abstract: A distributor plate (10) is shown for use in an impelling rotor of a vertical shaft impactor (14). Typically the impelling rotor is a chamber (12) arranged to rotate about a vertical axis A-A. Feed materials for breakage are gravity-fed into the rotating chamber (12). These materials strike the rotating distributor plate (10) which is located at the base of the rotor chamber (12). The plate has a substantially planar single-piece upper surface (24) onto which the feed materials are received. This substantially flat surface (24) facilitates rapid and easy expulsion of feed materials there across and out of the rotor chamber (12). The plate shown is a circular disc made of metal carbide. Use of a single-piece upper surface of the distributor plate (10) also will not result in the development of preferential wear sites at corners, edges, join lines etc, as can happen with the known distributor plates.

  • Patent number: 7753298
    Abstract: A rotor processor includes a stator chamber and a rotor mounted for rotation within the chamber. The rotor has a perimeter edge spaced closely to the interior wall of the chamber so as to define a slit or gap there between. The rotor is slidably mounted upon a rotor shaft, for movement between raised and lowered positions during operation of the processor, so as to automatically adjust the dimension of the slit, without operator intervention. As air flows from a plenum beneath the rotor, through the slit, and into the chamber, a pressure differential is created, which provides a lifting force to raise the rotor. The pressure drop is maintained relatively constant at a predetermined level after a lifting equilibrium force is achieved, regardless of the air flow volume.

  • Patent number: 7726597
    Abstract: An improved vertical shaft impactor rock crusher is provided. The improvement comprises an anvil having a front impact surface, a planar rear surface and a side surface extending between the front and rear surfaces. A shaft extends from the rear surface and can have a polygonal shaped cam lobe at the end of the shaft. When seated in the slot of a hanger bracket, the cam lobe keeps the anvil secured to the bracket while a side of the cam lobe rests on a seating block attached to the bracket to hold the anvil in an indexed position. When the impact surface becomes worn from use in the rock crusher, the anvil can be rotated within the bracket so that the cam lobe rests on an adjacent side thereby presenting an unworn surface to fracture feed rock in the rock crusher.
