Definitions

  • the present invention relates to a roller crusher and method for operating the same, particularly with an improved conveying, crushing and screening function.
  • rollers are used in various industries, e.g. mining and waste recycling, in order to separate material according to size.
  • the rollers each rotating in the same direction, form a conveyor surface that permits material of a certain size to fall therethrough and can also perform a limited crushing function to break up larger pieces so those also fall through the roller screen.
  • the main task of a "roller screen” is as a separator of particle size dictated by the gap between rollers, whereas a “roll sizer” or “roller crusher” is mainly for crushing to a particular size.
  • the terms can be used interchangeably because the device is intended to perform both functions.
  • a typical multi-roll screen or crusher comprises a series of rollers mounted side by side on a common axis plane.
  • the rollers are arranged to continually rotate in the same direction, driven by motors, to feed material across the machine between first and second ends while particulate material pass between the rollers having a defined size-gap therebetween.
  • Each roller typically includes a pattern of teeth or tools that urge material in a conveying direction and contribute to partially breaking larger pieces of material so, once the size is reduced, it can also pass between the rollers.
  • the capacity to break up larger pieces of material is fairly limited and often these larger pieces must be diverted from the second end to a further crushing machine stage.
  • a multi-roll sizer device may be configured with pairs of rollers rotating towards each other to better grab and crush material between the rolls. Further crushing at a second and subsequent stages may be performed by a further roll crusher which comprises two contra-rotating rollers specifically for breaking up feed material to a smaller size, often requiring it to be fed back to the first end of the sizer for screening.
  • Example sizers/crushers in the related fields of the present invention include WO2005072877, WO2012092952, US4691868, DE20208107 and WO201104184.
  • roller screens It is common for roller screens to be used to sieve the fine material and separate oversized particles, but challenging materials can tend to stick to the rolls and clog the screen area resulting in all material being transported to the second end of the machine. Large pieces are directed from the second end of the machine toward further crushing steps, i.e. in separate machines or to a discharge conveyor for separation.
  • a conventional multi-roll sizer can be used but feeding at high capacity is difficult because even distribution over the entire length of the device is not possible. Summary of the invention
  • roller sizer alternatively referred to herein as a roller crusher
  • improved function for conveying, crushing and screening which is able to process relatively high volumes of material without the need for multiple machines.
  • sizer crusher
  • the primary objective is achieved by providing a multi-roll processing apparatus and a method for operating same that features multiple rollers independently controllable for rotation speed and direction, preferably so as to react to the material layer formation across the roller surface, i.e. to maintain it with a relatively even distribution to ensure an efficient crushing and screening process.
  • a multi-roll sizer as described herein.
  • the multi-roll processing apparatus may comprise a first end and a second end, with a plurality of rollers arranged between said first end and second end defining a screen size between respective rollers, each roller including a plurality of radially extending tools which are cooperable with tools of an adjacent roller to crush material and/or convey it toward the second end; wherein a rotation speed and/or direction of the plurality of rollers may be independently controllable by a controller. Control of the speed and/or direction (i.e. at least one of these parameters but probably both) of rollers, either individually or in sets, enables the apparatus to be responsive to the distribution of the material layer upon the rollers, i.e. to align the layer thickness of material that effectively keeps an even distribution based on the height of the layer (i.e. total thickness).
  • there may be at least two sizes of screen i.e. the gap between rollers that dictates the particle size of material that can pass through
  • the smaller screens are located toward the first feed end and the larger screen is located toward the second end.
  • larger pieces of material are conveyed over the smaller screens toward the second end where they will be crushed by a larger screen/roller.
  • the apparatus drive system enables rollers to be driven individually or, at least, in groups.
  • Reference within the specification to the rollers being controlled independently encompasses each individual roller being independently controlled or at least two rollers that may be controlled as a pair or group independently of one or more rollers of the apparatus.
  • the rollers may be aligned at a common plane, i.e. horizontal axes of rotation, or arranged to be inclined, staggered or curved.
  • Each roll is equipped with tools that are configured for conveying, screening and crushing the material with no limit to the number of rollers.
  • any number of pairs of rolls can be operated in the manner of a double roll crusher/sizer, i.e. a contra-rotating pair, to increase the amount of screened and crushed material.
  • screening of fine material in the front section enables access to the bigger lumps of material to be crushed.
  • coarser material is conveyed in a transport direction, where one or multiple pairs of rollers are located, rotating in an opposite direction (to conveyance), thereby crushing the coarse material.
  • rolls of the second end section are designed for producing the same product size as rolls of the front area.
  • the crushed material can be led through a separate chute for further processing, e.g. to a secondary crushing stage.
  • the sizer to be operated is comprised of a housing having a first feed end and a second end, with a plurality of rollers arranged between said first and second ends, each roller including a plurality of radially extending tools which are cooperable with tools of an adjacent roller to crush material fed into the sizer and/or convey it toward the second end.
  • the rotation speed and direction of the rollers is controlled in response to a property of the material layer fed into the sizer.
  • the property of the material layer being monitored is height. Monitoring may be performed by any suitable means or method, such as an optical, capacitive or micro-wave system. Accordingly, a sizer operated according to the invention can be configured to automatically adjust the speed and direction of rollers in order to ensure an even or optimally processible distribution of material between the first feed end and second end.
  • the subject invention is advantageous in that conventional devices tend to be able to either crush material or screen it, but cannot do both in satisfactory manner.
  • a notable advantage of the invention is a reduction of the total number of machines required to crush and screen large volumes of material.
  • the working principle of the invention results in most of the fine material being screened and medium grain size material being crushed then screened.
  • the coarsest material is transported further in the conveying direction between first and second ends where it is also partly crushed and screened. Rollers adjacent the second end can be configured to crush coarse material to a medium grain size. This is advantageous if the coarse material is so large that the configuration of other rolls is unable to crush it.
  • the invention includes a secondary crushing stage which may have larger rollers and/or screening gap(s).
  • a multi-roll sizer (or crusher) according to the invention is able to handle a high volume (throughput) of material due to the possibility to operate rolls within a range of revolutions in a conveying direction as well as reverse to normal conveying direction. This enables the height/distribution of the material layer to be dynamically adjusted.
  • a particular advantage is to be able to adjust the conveying, screening and crushing amount according the requirements, which are dictated by varying feed quantity and/or different material properties. Changes in material properties cause different screening, crushing and conveying characteristics.
  • the concept behind the device optimizes the conveying, screening and crushing function due to different rotation speed and change of rotation direction of individual rolls. It is therefore possible to handle challenging materials, e.g. sticky brown coal / lignite, also including some wood fragments. Operation according to the invention reduces or avoids clogging of sticky material.
  • Another notable advantage of the invention is to handle a large amount of feed material with a low percentage of (very) coarse material.
  • a roller crusher comprising: a plurality of roller members, each having a longitudinal axis; a plurality of crushing heads projective radially outward from each roller member; a drive system configured to rotate each roller member about the respective longitudinal axis;
  • each of the heads comprise at least one first and second crushing tooth to allow each roller member to provide a crushing action in both a forward and reverse rotational direction; and the drive system is configured to rotate at least some of the roller members independently of one another and to rotate at least some of the roller members in either the forward and reverse rotational direction.
  • at least a part of the heads and/or teeth of each roller member overlap radially with at least a part of the heads and/or teeth of at least one closest positioned neighbouring roller member.
  • the heads and/or teeth of each roller member do not overlap radially with at least a part of the heads and/or teeth of at least one closest positioned neighbouring roller member.
  • the drive system is capable of changing a rotational speed of at least some of roller members independently of one another.
  • the first and second teeth are formed non-integrally with each respective head and may be detachably mounted at each head. Such an arrangement is advantageous to allow interchange of the teeth without needing to replace each crushing head.
  • the first and second teeth may be welded to each head or are formed integrally with each head.
  • the crushing heads are detachably mounted at each roller such that if damaged, the heads may be replaced without having to replace the entire roller.
  • the heads are positioned at each roller member in a spiral that extends axially along each roller member. Accordingly, the heads define a helix extending axially along the external surface of each roller. Such a configuration greatly facilitates neighbouring rollers acting as a pair to provide the desired crushing, screening and/or conveying function.
