摘要:
A gyratory roller crusher in which the rollers have a corrugated profile and at least one of the rollers is eccentrically mounted to give a relative gyratory motion to the rollers resulting in additional breakage mechanisms for the comminution of a very wide range of feed material, vastly improved crushing ratios and increased throughput compared with conventional roller crushers.
摘要:
A crusher having (a) a crusher frame, (b) a crusher rotor with teeth supported on the crusher frame, (c) counter-blade structures within the crusher frame; and (c) upper and lower hatches. The crusher rotor and the counter-blade structures are configured within the crusher so that material fed into the crusher frame can be crushed between the crusher teeth and the counter-blade structures. The upper and lower hatches are hinged to the crusher so that the hatches can be separated to provide an opening through which foreign material may be removed from the crusher while preventing material feeding into the crusher rotor from flowing out of the crusher.

The sheet manufacturing apparatus includes the defibrating unit configured to carry out a dry-type defibrating process on defibration object by rotating a rotating unit, and manufactures sheets by accumulating and heating at least a portion of defibrated material on which the dry-type defibrating process is carried out. The rotating unit includes a rotor that has a plurality of protruding sections on an outer circumference of the rotor, and a feeding blade configured to generate a flow of air and arranged on a side section of the rotor on a side of the input section for the defibration object.
摘要:
A mixing machine adapted to mix a liquid mixture containing bitumen with solid granules so as to obtain a homogenised bituminous mix. The machine comprising a cylindrical container arranged coaxially to a vertical axis and capable of containing the liquid mixture containing bitumen and the solid granules, a heating circuit for heating the inner side surface of the cylindrical container, a mixing assembly mounted axially rotatable within the container to rotate about the vertical axis, and a driving unit adapted to rotate the mixing assembly about the vertical axis. The mixing assembly comprises a helicoidal blade which extends coaxial to the axis within the container and has its outer peripheral edge in contact with the inner surface of the container so as to scrape the material adhering on the inner surface during its rotation.

An impact roll crusher for grinding up material, for example in mineral mining, employs a roll equipped with impact heads which co-operates with part of a conveyor transporting the material. The roll is rotatably mounted in a housing and a hood is connected to the housing to deflect and discharge the crushed material. The crusher roll is driven by a belt coupled to pulleys on the roll and on a drive motor shaft. The drive motor is supported by a bracket pivotably mounted on an inclined baffle wall of the hood. The roll drive adopts a position below the upper surface of the crusher housing. A tensioning device operable to adjust the tension in the drive belt is coupled to the bracket and adjusts the pivotable movement of the bracket.
