Definitions

  • the crushing device in contrast, allows the comminution of lumpy material to a final product with a very small grain size in a single operation and with only one device.
  • the first crushing roller and the second crushing roller which are engaged with each other, serve for pre-crushing the coarse material to be crushed, and immediately thereafter feeding the pre-shredded material to the third crushing roller.
  • the third crushing roll arranged below these two upper crushing rolls, which has the same distance from the first and second crushing rolls, d. H. is positioned centrally below the two upper crushing rollers and is engaged with both the first crushing roller and the second crushing roller, cooperates with the first crushing roller and in cooperation with the second crushing roller for post-shredding the immediately precompressed from the first and second crushing rollers material.
  • the comminution device therefore has low acquisition costs and low wear costs compared to the prior art. It also allows time savings due to the crushing of the material in a single operation and with only one device. Furthermore, the compact comminution device according to the invention, which enables both the pre-comminution and the post-comminution of the material to be comminuted, achieves considerable space savings, since in the prior art a plurality of devices, ie at least two devices, are required in order to comminute the material to be comminuted Pre-shred material and then chop it up. This also results in considerable advantages in the transport of the crushing device, since only this is a crushing device to transport.
  • a uniform comminution effect can be achieved over an entire length of the comminution rollers.
  • a distance between rotational axes of each two crushing rollers is less than a sum of radii of the respective crushing rollers. This expediently relates to the largest radius of the respective comminution roller, for example in the case of comminution rollers formed irregularly owing to their comminution geometry.
  • the first crushing roller and the second crushing roller are rotatable more slowly than the third crushing roller.
  • the pre-shredding is carried out by an opposite rotation of the slow-moving first and second crushing roller, which have a high torque by a corresponding gear ratio.
  • the crushing coarse, resistant material allows. This results in a rough tearing of the material to be shredded.
  • the crushing device thus combines the operating principle of the pre-shredder or crusher with the operating principle of the post-shredder designed as a hacker in a common compact device, so that the complete crushing of lumpy material to be shredded into a very small grain size of the crushed end product with this one compact crushing device and in a single operation is possible.
  • the first crushing roller and the second crushing roller are coupled to a common gear and the third crushing roller is coupled to another gear.
  • the first crushing roller and the second crushing roller are synchronized in this way drivable so that they rotate in opposite directions at the same speed.
  • the first and the second crushing rollers are also driven asynchronously by means of the common transmission, so that they rotate in opposite directions with different speeds. In this way, a cleaning effect can be achieved, so that clogging of the first and second crushing rollers with material to be crushed occurs less frequently.
  • the third crushing roller is driven by the separate gear independently of the first and second crushing rollers and thereby at a different speed.
  • all three comminution rollers are each coupled with their own gear.
  • the wave-shaped or cylindrical base body and / or arranged on this, designed as a shredding tool tool discs of the respective crushing roller are suitably made of metal, in particular of steel. At least the tool disks are preferably made of a hardened steel.

  • each of the three crushing rollers ie the comminution tools of each comminution roller are each arranged offset relative to the comminution tools of the two respective other comminuting rollers. In this way, the comminution tools of the comminution rollers run past each other laterally so that the comminution rollers mesh with one another.
  • a distance of the third crushing roller to the first crushing roller and the second crushing roller is adjustable.
  • the third crushing roller is mounted horizontally and / or vertically movable and / or pivotally mounted, so that it is to be moved out of the normal operating position.
  • a pivot axis, about which the third crushing roller is pivotable, then runs parallel to the axis of rotation of the third crushing roller.
  • the further gear of the third crushing roller is expediently coupled to the crushing roller and adjustable together with it, so that the above-described distance adjustment of the third crushing roller relative to the first and second crushing roller is made possible.
  • This distance adjustment is preferably carried out hydraulically, but may alternatively be done for example pneumatically, motorized and / or manually, wherein the respective adjustment can also be coupled via an adjusting gear with the third crushing shaft.
  • the common gear of the first and second crushing rollers is suitably fixedly connected to other components of the crushing device, in particular to a roller holder.
  • first and the second comminuting rollers each have their own gear, then these two gearboxes of the first and second comminution rollers are expediently firmly connected to other components of the comminuting device, in particular to a roller mount.
  • This resilient storage is preferably hydraulically, d. H. via at least one also used for adjusting the distance and formed from cylinder and piston hydraulic unit.
  • the hydraulic system then has at least one pressure accumulator, also referred to as hydraulic accumulator, hydraulic accumulator or accumulator.
  • This accumulator acts as a spring element of the resilient mounting of the third crushing roller.
  • the pressure accumulator is designed, for example, as a hydropneumatic accumulator, in which a gas is compressed by a corresponding fluid pressure of the hydraulic fluid.
  • the pressure accumulator may be designed such that a spring is compressed by the fluid pressure or a weight is raised. In this way, a maximum pressure on the hydraulic unit is predetermined by the pressure accumulator.
  • the tool disks of at least one of the comminution rollers are interchangeably arranged on the respective base body.
  • the tool discs are preferably positively and / or non-positively attached to the respective base body, for example, they are locked to the base body and / or screwed and / or clamped by at least one clamping element. If the tool disks are not to be interchangeable, then they can also be fastened on the respective base body, alternatively or additionally, by a material fit. For example, they are welded to the base in such a case.
  • FIGS. 1 to 8 show different views of a crushing device 1, which may be formed as a stationary or as a mobile crushing device 1.
  • the comminution device 1 has a chipper in which three comminution rollers w1, w2, w3 are arranged. It is therefore in the crushing device 1 to a three-roll crusher.
  • the chipper is supplied from the top of a feed hopper to be shredded material.
  • the feed hopper has in the illustrated embodiment, two Zuzhoutrichtertown z1, z2.
  • a not shown here larger funnel for feeding the material to be shredded is expediently arranged.
