  • Publication number: 20210354148
    Abstract: A portable grinding/shredding/chipping system with a drive track assembly which is manipulatable to facilitate altering the orientation of the portable grinding/shredding/chipping system. This arrangement results in improved loading and processing, of both long and short materials, as well as facilitates connection of a transport dolly and a transport truck/tractor without requiring any additional lifting mechanism. A pivotable housing provides greater access to the rotor and has an over-center arrangement which prevents the pivotable housing from inadvertently moving or pivoting back into engagement with the rotor. The portable grinding/shredding/chipping system is provided with a belt drive assembly which facilitates modification of the rotational speed of the rotor by merely replacing a sheave of the belt drive assembly. Lastly, both head and tail pulleys are driven by a respective motor so that a catinary of the discharge conveyor is radiussed which shortens an axial length of the system.

  • Publication number: 20210325037
    Abstract: A combustion/pyrolization system comprising a combustion/pyrolization chamber supported by the base frame, and a perforated grate forms a bottom surface of the combustion/pyrolization chamber and facilitates passage of char and boichar therethrough. The combustion/pyrolization chamber is open along at a top and an air manifold supplies a first source of combustion air across the top of the combustion/pyrolization chamber to form an air curtain. A char collection/transfer chamber is located below the perforated grate for collecting at least the char and boichar that passes therethrough, and a conveying mechanism transfers the char and boichar out of the combustion/pyrolization system for collection and use. An air plenum chamber cools the char collection/transfer chamber such that the supplied secondary air becomes heated, and the heated secondary air flows into the char collection/transfer chamber and through the perforated grate into the combustion/pyrolization chamber to provide secondary combustion air.

  • Publication number: 20210276837
    Abstract: A swivel hook assembly which comprises a hook unit that supports a hook which facilitates suspending a desire piece of equipment from the swivel hook assembly. The hook unit is engageable with a free end of a wire cable that controls vertical and horizontal movement of the hook unit. A hook coupling has an upper end which engages with a jib and a second end for engaging with the hook unit. When the hook unit is spaced away and disengaged from the hook coupling, the hook unit is rotatable relative to the hook coupling. However, when the hook unit is moved, by the wire cable, into engagement with the hook coupling, relative rotation between the hook unit and the hook coupling is prevented and more precise control over the suspended desire piece of equipment is achieved by the operator.

  • Publication number: 20210199288
    Abstract: A combustion/carbonizing system which comprises a base frame and a combustion chamber frame which is pivotably attached to the base frame. The combustion chamber frame defines an open top combustion chamber having a bottom perforated plate. A plenum is formed below the perforated plate for collecting biochar which passes therethrough. A first source of combustion air is supplied across the top of the combustion chamber while a second source of combustion air passes through the perforated plate into the combustion chamber. The combustion/carbonizing system is capable of operating in a continuous manner for combustion wood or waste material to the desired degree required by the end user for the purpose of reducing the volume of the material as well as the associated emissions while generating valuable char and boichar as an end product. For some applications, the combustion/carbonizing system may be operated to combust completely the wood or waste material.
