Abstract

A description is given of a method for controlling the material feed to a roller mill for continuous grinding of particulate material, such as cement raw materials, cement clinker and similar materials, which roller mill comprises a substantially horizontal grinding table (1) and a number of rollers (2) operating interactively therewith, said rollers rotating about separate roller shafts (3) which are connected to a vertical central shaft (4) via a hinged connection (5) allowing a free circular movement of the roller up and down in a plane comprising the centreline (6) of the roller shaft, where material to be ground is continuously fed to the roller mill, with ground material being continuously diverted from the roller mill. The method is peculiar in that an angle (α ) between at least one of the roller shaft centrelines (6) and a reference line (18) is measured and used as an input signal for a control circuit for controlling the material feed. Hereby is obtained a fast and adequate control of the material feed which takes due account of the immediate operating environment in the roller mill in terms of material charge, ie the amount of material present in the roller mill at any given time. This is due to the fact that variations in the angular positions of the roller shafts will provide a prompt and significant indication of any tendency towards overfilling or emptying of the mill.

Description of the Invention: [Technical Field of the Invention] The present invention relates to a control device for feeding materials to a continuously milled roll mill for particulate materials such as cement raw materials, cement clinker and materials. ^, including a substantially horizontal grinding platform and a multi-dip operation = = 昆 旋 around the respective reel axis 'the roller shaft is connected to the central axis via a hinge joint' allows the pro-inclusion The in-plane rotational motion of the center of the light shaft, wherein the material to be ground is continuously fed to the light mill, and the can is continuously transferred away. The invention also relates to the execution of: [Prior Art] It is known that the __mill is, which means that it cannot be operated in a connected manner, but rather every 1 line, 枓, process and empties - part of the material dingding package The continuous grinding of the mill's particulate material is known to be 'continuously fed to the roller mill by other rollers, so that the mill comprises a gas for introducing the material "from the roller The mill is continuously placed by the nozzle ring. The common feature of these continuously ground roll mills removes the need for the assembly of the ground material - some form of control to ensure the grinding,: The amount of material, and they do not ring to cause the most normal change in the grinding effect, and excessive loading or emptying for the control of the wearability and other properties is usually based, for example, on the two known mills. The material enters the J power consumption, which is used as a control circuit for the loss of the two voltages 5 or the mill motor and they are indirect and delayed by other drops, resulting in control delays, consumption or other factors. Number such as separator loop factor, air 201043336 • [Description of the Invention] It is an object of the present invention to provide a granulating material point which is fed to, for example, a forgotten continuous grinding roll mill. The control method can thereby eliminate the aforementioned deficiency,特征The characteristics are in control (4) (4) The reversal (4) angle can be used to properly and quickly according to the amount of material present in the grinding machine in any roller mill in the material mill. Control. This is due to the fact that the material feeds = any tendency to provide excessive loading or emptying of the mill and that the belt f mentioned by f is hinged independently of each other __ Roll mill, during operation of the mill, in response to the grinding bed (the coffee sound =, the light will move up and down independently of each other, the axis of: ❹L, however 'in some cases' use a few or The average of the angular positions of all the rollers may be advantageous, and in this scheme, the angle between the center of the pump and the one or several reference lines can be measured, and the average value can be calculated. And use the average value as the (four) circuit for controlling the feeding of the riding material. Is there a = only one benchmark money 'use of the center of the vertical center axis may be in principle, the threat is appropriate _ 4 loaded seam roller shaft heart loss = angle between the money', the measuring device It is possible to provide reliable measurements in the mill under conditions of poor temperature and dust, etc. As an example of a suitable device, 201043336 - is a displacement sensor. • 3. The specific implementation of the method according to the invention is connected The specific setting parameter of the mill is characterized by the method of inventing the value parameter, and according to the method of the present invention, the control unit will carry Decrease === control. If the measured feed system, in order to avoid the excessive fading of the mill and vice versa: the signal of the command is transmitted to the flat grinding machine, which comprises a substantially water roller shaft rotation' The roller shaft surrounds the respective roller at a center axis including the center of the roller shaft via a hinge, and the material to be grounded is continuously fed to the machine machine 2: For the material from the light grinding a device for continuously transferring the machine for measuring at least one roller center line and eight or four for the ground material, wherein the roller mill includes a device for measuring the angle of the crucible with a fine material and for [Embodiment] He, the input signal of the control circuit of °. In the drawings, a roller mill can be seen which encloses a coffee-rotating roller 2 which is freely rotatable about a plurality of places. In the in-plane upper and lower 9 of the H 6 and the feed pipe material container 8 with the feed gate u, the conveyor belt material is continuously fed to the wearer 〇 == the device 7 for A device in the form to be ground for the material that has been ground by the illustrated fan and nozzle ring 12 (diversion). < The roller mill continuously transfers away. The step of the mill includes driving the pure 13 for the grinding platform 丨 6 201043336 crying = medium. The shaft 4' 幷 and thus rotates the roller 2, and the separator μ, which separates the ground material transferred from the grinding region into fine particle portions and coarse particles. At the gas age and transferred through the outlet raft, the granules are re-arranged via the hopper 16 to the grinding platform 2 to the shovel, according to the immediate operating environment in the tank; =: With sufficient control, the apparatus of the roll mill according to the present invention is used to measure the angle 01 between the center of the roller shaft 6 and the reference weight 18 。. The measuring device 17 and the control unit 19 form ^ 0 = (four) the unit 19 can connect the measured temperature to the human signal, and the signal is transmitted to the feeding system 7 for controlling the When the roller mill is in operation, the signal received by the control unit quantity device will be sent with the maintenance, reduction or addition of the test signal to the feed system 7. If the measured angle is reduced, the ninth command sends a signal to the feed system 7 to ensure that the control list is thereby prevented from transiently loading the mill, and vice versa. Reduction of °, Ο [Simplified description of the drawings] μ The present invention will now be explained in further detail with reference to the accompanying drawings, only the roller mill for carrying out the method according to the invention.
