Definitions
- the present invention relates to a method and a device for comminuting ore material or rock and / or slag in particular, wherein the ore is pulverized using water in the wet process or even without the use of water in a dry process in a particularly ecological manner.
- the grinding cylinder In such known ball mills, however, the grinding cylinder must be designed to be particularly robust in order to be able to withstand the impact of the balls on the cylinder wall without damage, as a result of which the weight of the grinding cylinders increases greatly. As a result, the operating costs and energy consumption of such ball mills are high. Furthermore, there is a high wear of the rotating grinding cylinder due to the
- ball mills are not suitable for crushing or pulverizing ore material together with slag or slag, since slag, which arises in particular during the further processing of ore as a waste product, is very brittle and has a hard structure.
- the invention is based on the idea of providing a method and a device for comminuting ore material, wherein the device according to the invention comprises an ore feed device for feeding ore to be comminuted to a pulverizer.
- the Pulverisier founded is at least composed of two mutually movable crushing elements, which together form at least one crushing space for the ore to be crushed that is pulverized by a relative movement in the form of a rotation of at least one of the two crushing the ore to be crushed by at least one one or more acceleration elements, in particular projections, are provided in the comminuting elements, which are arranged in particular on the front side of one of the two comminuting elements and which accelerate and thereby comminute the ore to be comminuted by the rotation of one of the two comminution elements.
- One of the effects of ore is the direct action of one of the two crushers. pulverized in that in the crushing space ore material with different direction of movement and different speed of movement due to the rotation of the accelerating elements, wherein the projections or recesses of the accelerating elements in particular by the oblique relative to the front angular range of the ore to be crushed away from the angular range in the direction of the other crushing element or accelerated towards the crushing space, so that a coincidence of this differently accelerated ore material provides for a pulverization by a so-called micro-impact of ore material.
- the result is an acceleration of the ore to be comminuted in a particularly simple manner due to the rotation or the different relative speeds of the two comminuting elements.
- the two crushing elements may rotate in opposite directions, or one crushing element is fixed, and the other crushing element rotates to achieve relative movement between the two crushing elements.
- the acceleration elements or the projections act on the ore to be comminuted such that ore to be crushed is moved away from the acceleration elements or projections or recesses with an oblique angle range such that a portion of the ore to be comminuted by the Protrusions in the direction of the other crushing element or in the direction of the crushing space is accelerated and meet there with other parts of the ore to be crushed to form a micro-impulse, since the different accelerated parts of the ore in the crushing space between the two crushing elements to form a micro-impingement meet and so
- the micro-impact between differently accelerated parts of the ore provides for a particularly advantageous pulverization.
- the ore to be comminuted is accelerated by the acceleration elements in that they have an oblique region or angle region in the form of projections or recesses which, due to the rotation of the comminuting element, have a defined angle between the end surface of the comminuting element and due to the rotation of the comminuting element forms rotating acceleration element, wherein the accelerated from the accelerating elements ore and an ore with another relative speed or another direction of acceleration to form a micro-impulse coincide, thereby providing a particularly advantageous pulverization in the crushing space.
- the pulverized ore After pulverization in the crushing space between the two crushing elements, the pulverized ore is conveyed from the center of outward rotation, in particular due to centrifugal force and gravitational force, into a space provided between the two crushing elements and / or at least one of the two crushing elements.
- the pulverized ore passes from the intermediate space to an outlet device, in which case it is collected by means of the outlet device, for example due to gravity, or is sucked off through the outlet device in order to discharge the pulverized ore from the device according to the invention.
- the ore Due to the collision of the ore to be comminuted with the accelerating elements and the further micro-impact between the differently accelerated ore in the crushing space, the ore is pulverized in a particularly effective manner, in contrast to known devices, the pulverization in a short time and in a crushing chamber with low Dimensioning takes place, which means that the device according to the invention has only small dimensions in its dimensions. As a result, the dimensions and in particular the wall thicknesses of the rotating and possibly also fixed crushing elements are low, and accordingly only a small amount of wear occurs and a high degree of efficiency is achieved.
- Another significant advantage of the device according to the invention and the method according to the invention is that pre-crushing of the ore obtained from the mining is not required and thus the device according to the invention not only the known ball mills, but also corresponding devices for pre-crushing ore material replaced, in particular two mutually rotating rollers can be constructed.

Due to the rotation, which due to the dimensions 100 to about 2000 revolutions per minute of a crushing element can also be effectively powdered slag, which is very brittle and has a hard structure.
- the acceleration elements which are attached to both the one comminution element and the other comminution element, provide a particularly effective micro-impact due to their different relative speeds, in particular if the acceleration elements of the one and the other comminution element are aligned with each other in such a way that the ore elements to be comminuted in each case accelerated by the acceleration elements of the one and the other crushing element substantially in opposite directions, thereby characterized the effecting rapid and effective pulverization of the ore material.

- the recesses in the front of the crushing elements are a particularly simple design to accelerate the ore to be crushed.
- the recesses can also form corresponding projections, wherein in particular both in the recesses and in the projections, an angular range is particularly advantageous, which is formed between the outer face of the crushing elements and the recesses, since this angular range can be made obliquely such that the Rotation of the crushing element provides for an effective power transmission to the ore to be accelerated.
- the comminuting space between the fixed element and the rotary element is designed to taper outwards in a substantially conically tapering manner from the axis of rotation of the rotary element.
- the rotation of the rotary member by a gear or an adjustable belt drive is variable, so that the engine can be driven in each case with optimized operating parameters.
- the rotary element has a ramp region with increasing pitch as part of the comminution space through which the ore and / or in particular slag to be comminuted is accelerated and comminuted, then in addition to the protrusions or recesses, an advantageous comminution of ore and / or slag can be achieved be done with the rotation of the rotary member different cross section of the ramp area.
- the ramp region is provided in the transport direction of the ore material and / or the slag after the feed opening of the fixed element and before the projections and / or recesses of the two comminution elements, in order to be pre-comminuted by pulverization by the protrusions and / or recesses to care.
- the intermediate space between the two comminuting elements is adjustable in the axial direction of rotation by a variable distance between the two comminution elements, wherein the interspacing comprises in particular star-shaped Auslass incisions in the rotary element or the fixed element leading away from the axis of rotation of the rotary element.
- the variable adjustment of the distance between the two crushing elements the pulverization and thus the average grain size of the pulverized ore material can be varied. That is, with a larger distance between the two crushing elements, the pulverized ore has a larger average grain size, and with a smaller distance between the two crushing elements, the average grain size of the pulverized ore is smaller.
- the final result of the pulverization by the operating personnel can be predetermined as desired.
- these ramp areas in the form of a worm can extend over a radial region on the end face of the two comminuting elements, so that together they provide for a reduction in the size of the ore immediately after feeding the ore to be comminuted and accelerate it.
- water is supplied into the crushing space through a water inlet and transported away through the outlet device together with the pulverized ore.
- the use of water to pulverize the ore may favor the pulverization process, with the supply of water not necessarily required. On the other hand, the supply of water reduces the formation of dust, which can have significant health consequences for the operating personnel.
- the pulverizer has a water inlet into the crushing chamber, through which water is supplied to the ore to be crushed according to a predetermined amount.
