Definitions
- the invention relates to a ball mill with a housing which houses a carrier device with grinding stations in a grinding chamber and can be closed with a housing cover, in particular a planetary or centrifugal ball mill on a laboratory scale.
- Lab scale ball mills are used for a wide range of applications, in particular for crushing and mixing samples and for mechanical alloying.
- An overview of common laboratory mills can be found on the applicant's website at www.fritsch.de.
- grinding bowls are arranged eccentrically to a center axis and move on a circular orbit about the center axis. As a result of the rotation of the grinding bowls, a centrifugal force directed radially outwards is exerted on the grinding stock.
- Planetary ball mills thereon to create by additional rotation around the Mahlbecherachse in the laboratory system, a combined rotational and rotational movement for the Mahlbecher.
- the drive of the grinding bowls in a planetary ball mill thus causes an absolute rotational movement of the grinding bowl about its own axis, the receiving or planetary axis, so that in a planetary ball mill compared to a centrifugal ball mill a significantly larger, further centrifugal component is generated. This is superimposed on the centrifugal component, which is generated by the circulation of the grinding bowls about the center axis.
- a planetary ball mill With certain dimensions of the rotating parts and certain rotational speeds trajectories for the grinding balls are generated in a planetary ball mill.
- the grinding balls then move across the grinding bowl until they impinge on the inner wall of the grinding bowl. Thereafter, the grinding balls are taken along the inner circumference of the grinding bowl until the resulting force again ensures that the above-described transverse movement takes place and grinding balls perform a flight movement through the grinding bowl.
- This is also referred to as "Wurfregime”.
- a planetary ball mill can achieve a significantly better grinding effect at higher speeds.
- Such laboratory planetary ball mills are usually built with one, two or four grinding stations.
- the grinding stations are rotatably mounted as planets on a sun disk, which is designed as a support device for the grinding stations, wherein the carrier device rotates relative to the housing.
- the grinding stations each include one Receiving device and at least one grinding vessel which is mounted in the receiving device.
- the receiving devices are arranged completely above the carrier device and are mounted in a flying manner on the carrier device.
- An example of such a planetary ball mill with a grinding station and a leveling compound is sold under the brand name "pulverisette® 6" (see www.fritsch.de) and is described in DE 197 12 905 C2.
- the known mills have a housing to house the carrier device with the grinding stations, the drive and the control of the mill. Due to the structural design with the cantilevered receiving devices above the carrier device, the vertical extent of the movable or rotating parts is already relatively large. In addition, the grinding jars are clamped with screw terminals, which again need space upwards. On the other hand, the rotating parts should be completely enclosed within the housing for safety reasons. Therefore, in these ball mills, the grinding space, ie the interior of the housing housing the rotating parts, must be relatively bulky. In order to reach the grinding jars when the mill is at a standstill, the mill has a large, essentially scoop-shaped pivot lid, which is swung open to the top.
- the opening is done manually and allows access to the entire carrier device, in particular all grinding stations at the same time, which may be difficult for the user to distinguish at several grinding stations, especially if the same grinding jars are used.
- incorrect operation eg with different ground material in the grinding stations possible.
- a disadvantage of this case is also the large footprint already the case in the closed state, even more in the open state.
- the opened lid can be annoying when accessing the grinding jars.
- Another object of the invention is to provide a ball mill, which allows the standard user as possible only the necessary intervention options in the operation of the mill to reduce operating errors and a particularly high level of the
- the invention provides a ball mill, in particular a planetary or centrifugal ball mill on a laboratory scale, which comprises a housing that houses the functional components, in particular the rotating parts of the mill.
- the support device rotates in operation within an interior in the housing relative to this about a center axis, on which the support device is rotatably mounted.
- the carrier device further comprises at least one grinding station with a receiving device for at least one grinding vessel, which rotates in operation about a receiving axis, preferably opposite to the carrier device, and at the same time of this as a "planet" in an orbit about the center axis or
- grinding balls is not limited to spherical grinding media, but comprises grinding bodies of various shapes.
- Each grinding vessel comprises a grinding bowl, which can be closed with a grinding bowl lid and fixed in the receiving device in order to make the mill ready for operation and to grind the material to be ground in the grinding vessel.
- Drives drive the rotation of the carrier device and the rotation of the receiving devices or grinding stations, wherein preferably an electrical total drive motor via a translated according to the desired speed ratio belt drive drives both rotations, as the skilled person is basically known and described for example in DE 197 12 905 C2 is.
- the housing defines and encloses the interior space in which the carrier device rotates with the grinding stations.
- This interior is referred to herein as a "grinding chamber” and is not to be confused with the interior of the grinding vessels
- the housing has a housing cover which can be opened when the mill is at rest to allow the user access to at least one grinding station around a grinding vessel In other words, the housing cover can be moved from an open to a closed position and vice versa, wherein in the open position access for the user to at least one grinding vessel is made possible and the ball mill is operated in the closed position can be.
- a one-piece upwardly swing-open housing cover is not used, but the housing cover is formed at least in two parts, wherein the two lid parts interlock and are shifted from each other to open the housing cover and close ,
- the two cover parts which is referred to below as the cutout lid part
- a cutout which in the open position, the access opening for the user to the grinding station or a section the carrier device defines
- the other cover part which is also referred to below as the closure lid part, closes the cutout by relative displacement to the cutout, preferably in the plane of rotation of the carrier device.
- the lid according to the invention is considerably more space-saving and user-friendly. Furthermore, the two-part lid according to the invention can be driven automatically with low design effort motor, which further improves the ease of use.
- the two lid parts are thus rotated to open and close parallel to the plane of rotation of the carrier device or coaxially to the center axis relative to each other.
- the two cover parts are preferably hat-shaped with an upper end face and an at least partially encircling edge, wherein the two cut cylindrical hat shapes mesh suitable rotatable and thus at least partially lie flat against each other.
- the cutout extends at least in the end face and optionally beyond the annular connecting edge between the end face and the edge, so that optionally also a portion of the edge is cut out.
- the two lid parts are each cut sector-like and the cutouts are brought by relative rotation of the two lid parts to each other in overlap to define the open position and access through the access opening to the Grinding station release.
- the non-cut portion of the closure lid part covers the cutout of the cut-out lid part and vice versa.
- the cutout lid part preferably has a sector cutout of greater than 45 degrees, preferably greater than 90 degrees and less than 180 degrees, preferably 150 degrees
- the non-cut portion of the closure lid part is larger than the sector cutout.
- the two sector lid parts can be similarly shaped each with a sector cut slightly smaller than 180 degrees to provide the largest possible access opening in the open position and yet in the closed position, the two sections mutually completely close.
- the term "sector" is not to be understood in a mathematically rigorous sense: for example, in a preferred embodiment, the cutouts do not extend to the axis of rotation in order to ensure sufficient overlap of the two lid parts there as well.
- the relative displacement of the two cover parts relative to one another can take place in that one of the two cover parts, in particular the outer, is stationary and only the other, in particular the inner, is displaced or rotated in the plane of rotation of the support device, around the housing cover to open and close.
- the fixed lid part is connected to a horizontal lid base plate of the housing and the inner lid portion has a lower ring portion with a circumferential guide ring.
- the guide ring is guided under the lid base plate in a plurality of bearing rollers arranged along a circumference and rotatably supported.
- the housing cover is preferably driven by a separate from the overall drive motor of the support device electric motor which is electronically controlled by the control device of the mill.
- the opening and closing takes place essentially as part of a sequence control of the grinding process.
- the drive motor is preferably designed as a DC motor and is reversed to rotate the rotatable housing cover part in both directions to open or close.
- the drive is preferably carried out by the drive motor via a worm gear, which drives a toothed belt via a toothed belt, which is connected to the rotatable cover part.
- the toothed belt is attached to the rotatable lid part at two points and is constantly engaged with the motor.
- a pinion can be used which meshes directly with teeth which are mounted on the cylinder jacket of the rotatable lid part.
- the worm can mesh directly with teeth or "gills" on the cylinder jacket, so that the rotatable cover part practically represents the worm wheel.
- a limit switch are attached to the housing cover for the closed and the open position, which are connected to the control device and report the achievement of the fully closed or open position of the housing cover to the control device, so that the control device in response to the message can close the closing or opening in the correct rotational position.
- the limit switches are preferably designed as non-contact magnetic switches, which are advantageously robust and insensitive to dirt.
- at least one magnet is fastened to the rotatable cover part, which in each case actuates a fixed Hall sensor for the open or closed position. In the normal case, one of the limit switches thus gives the stop signal for the motor in the open or closed position.
- the mill has a safety circuit which monitors at least the closing of the housing cover continuously to a blockage of the rotatable lid part and terminates the closing when a Obstacle, for example, based on an increased torque is detected.
- the current at the drive motor is particularly easily monitored, which is a measure of the torque required for closing.
- the control device detects an increased current flow If a predefined limit value for the motor current is exceeded, the closing process is stopped immediately and the housing cover is opened at least a little.
- control device may include a timer, which monitors the duration of the opening or closing until the message of the associated limit switch and also breaks off the opening or closing of the housing cover after exceeding a predefined maximum time duration. This is advantageous if, for example, one of the limit switches is defective.
- the access opening allows the user in the lid shape according to the invention access preferably only to a portion of the support device, in particular only to a single of the grinding stations to insert or remove the associated grinding vessel.
- the control device allows a user input, which includes the selection of a specific grinding station.
- the mill preferably has one
- Angle detection device for determining the absolute angular position of the support device relative to the housing and automatically rotates the support device in response to the user input and the determination of the angular position to a position in which is provided with an open housing cover manual access to exactly this selected grinding station.
- the control device automatically opens the housing cover. For example, with two existing grinding stations "# 1" and "# 2", the user indicates that he wants to load the grinding station "# 1", whereupon the control device turns the grinding station "# 1" to the position where, in the opened state, the grinding station Access opening is located, which is preferably on the user-facing side of the housing.
- control device is designed such that it can rotate the support device automatically, possibly in response to a corresponding user input in a desired angular position or stop there.
- the angle detection device preferably comprises a coded arrangement of magnets on the carrier device and associated Hall sensors on the housing.
- Angular position of the carrier device enter one or more of the magnets in the sensitivity range of one or more of the Hall sensors. These are read out by the control device and the control device determines based on the spatial coding of the magnets at least in some rotational positions, the absolute angular position of the support device.
