Definitions

  • the invention relates to a mobile crushing plant with a receiving bunker for the crushed material and at least two counter-rotating rollers, between which it is formed in the working gap for the crushing of the crushed material.
  • Mobile crushing plants are often used in the extraction of mineral substances such as ores and rocks, organic substances such as coal, and for the continuous overburden extraction.
  • the corresponding materials In order to be able to remove the exploitable material or spoil from an extraction area with conveyor belts, the corresponding materials must not exceed a certain grain size.
  • the mobile crushing plant Since the loading of the crushed material is carried out discontinuously by an excavator or wheel loader, but the removal by means of conveyor belts should be continuously possible, the mobile crushing plant must also have a certain buffer function so that a continuous conveyor belt filling and a high throughput can be achieved during continuous operation of the crushing arrangement can.
  • double roller crushers jaw crushers with pre-screening or even cone crushers are used in practice for mobile use. These crushers require a relatively large height to ensure an unhindered inflow, a reliable crushing process and a uniform crushed material discharge.
  • the crushed material which is filled discontinuously in the comparatively low receiving bunker, is conveyed to the crusher with a plate belt.
  • the mobile crusher must also have facilities for removing the broken material, such as a discharge boom.
  • the receiving bunker, the Piattenband, the crusher and the discharge device are arranged with a corresponding support structure.
  • US Pat. No. 5,595,350 A describes a multi-roll crusher at the end of a cooling device, four crushing rolls being arranged next to one another. From the feed side, the first rolls rotate in a same direction to the right, with the fourth turning counterclockwise to the left. The material is passed on from the task side.
  • the present invention has for its object to provide a mobile crushing plant, which has a low overall height, a compact design and low weight at a high throughput.
  • the mobile crushing plant should have good maneuverability to allow in practice a simple and flexible use.
  • Rolls are arranged directly in the receiving bunker and that within the receiving bunker means for screening particles from the crushed material, which fall below a predetermined grain size, is provided. Because the at least two rollers are inserted directly into the receiving bunker, it is not necessary to have a crushing space for the rollers and a separate receiving bunker kept separate. In addition, long slats for transport and an elaborate support structure for different parts fall away. For a given throughput, thus the weight of the mobile crushing plant is significantly reduced.
  • a compact design with a high throughput is also favored by the fact that according to the invention a device is provided for screening particles from the crushed material which fall below a predetermined grain size. Particles which already have a suitable size for further transport or further processing so do not reach the at least one working gap, whereby this is acted upon only with a reduced flow of material, whereby the total throughput is significantly increased. Small particles already having a desired size are immediately removed by the sieving means. For this example, vibrating grid or roller grates are suitable, which are upstream of the rollers, ie the crushing rollers.
  • the means for screening of particles may also be formed by two adjacent rollers having a same direction of rotation, which define a screen gap between them.
  • These rollers are expediently designed as crushing rollers with teeth, whereby a shaking movement of the crushed material is generated and whereby particles which do not fit through the sieve gap between the two rollers rotating in the same direction, are transported further.
  • the crushing material In order to enable a loading of the mobile crushing plant with an excavator or wheel loader, there is expediently a task area for the crushing material to be crushed on one side of the receiving bunker.
  • the crushed material then passes from the feed area first to the device for screening particles before the non-sieved components of the crushed material are fed to the at least one working gap.
  • increased throughput can be achieved by screening based on size selection.
  • Particularly preferred is an embodiment of the mobile crushing plant with at least five rollers which are arranged in the receiving bunker that there are at least two working gaps and an empty gap at which the adjacent rollers rotate in opposite directions, and in addition a sieve gap between two adjacent rolls, the have a same direction of rotation is present.
  • the breaking power can be further increased, wherein the working gaps, as explained in detail below, can in principle also be designed for breaking in each case different grain sizes.
  • a first section is provided with at least two directly adjacent rolls having a same direction of rotation, wherein a second section following the first section for breaking a middle grain fraction comprises at least two rolls having a same direction of rotation and a roll arranged offset down between these rollers with an opposite direction of rotation, and wherein a second portion subsequent to the third third section for breaking a coarse grain fraction at least one

  • a plurality of rollers are integrated directly into the receiving bunker in such a way that they bring about a transport and screening function, a size selection as well as the breaking of the middle grain fraction and the coarse grain fraction.
  • the task area is usually provided on one side of the receiving bunker. Starting from this side of the receiving bunker, the crushed material passes directly or via a comparatively short conveying device within the receiving bunker to the device for screening particles. If at least one screen gap is provided here, the rollers are driven such that they move on their upper side away from the application area in the direction of the at least one subsequent working gap. A breaking function is not provided in the first section. Due to the at least one sieve gap between the rolls, however, the fine grain portion of the crushed material can fall through, so that an effective screening of this fine grain fraction takes place.
  • the rolls can expediently be provided with teeth, like conventional breaking rolls, having teeth whose tips point in the direction of rotation.
  • teeth like conventional breaking rolls, having teeth whose tips point in the direction of rotation.
  • the crushed material is set in movements that facilitate the separation of the fine grain fraction.
  • larger particles that can not pass through the nip are transported by the teeth from roller to roller.
  • the number of rolls in the first section can be selected on the basis of the respective requirements and the size distribution of the particles in the crushed material
  • rollers can be arranged one behind the other.
  • the rollers of the first section are arranged with their axes preferably rising on a straight line and / or in the direction of the subsequent section. Due to the increase, starting from the application area, the first roller can be arranged very deep directly above the bottom of the receiving bunker, so that the entire height of the receiving bunker can be used there for receiving and buffering the usually discontinuously placed crushed material. The slope at the same time sufficient space is created to subsequently arrange rollers with a height offset to each other. Finally, the separation is improved because the crushed material is conveyed against gravity.

  • Coarse grain which does not get into the gap between the two rolls due to its size, is conveyed further by the rectified rotation to the third section. Particles of average grain size, on the other hand, may fall into the nip between the two rolls of the second section rotating in the same direction and are then comminuted by cooperation with the oppositely rotating roller below.
  • the described arrangement can be present several times in the second section.

  • the mobile crushing plant is characterized by a compact design and low weight. Even if large throughputs of at least 800 tons per hour (t / h) or preferably more than 1000 t / h are provided, the chassis of the mobile crushing plant can be formed from only two rows of feed trains, in particular two parallel tracks.
