Definitions
- the invention relates to a mortar mill for laboratory purposes in particular with a grinding bowl which holds the ground material, in which a pestle is movably arranged as a grinding body and a drive device for the pestle
- the object of the present invention is to provide a mortar mill in which a gastightly closed device can be made available for the grinding process, and which is simple and effective in its operation in such a way that a The grinding bowl can be replaced with little effort.
- the invention is associated with the advantage that, due to the driving force exerted on the pestle by a rotating magnet, the lid of the grinding bowl is now none
- a further advantage is obtained with regard to the grinding forces acting in the mill, in that the magnet which rotates the pestle simultaneously pulls the pestle against the base of the grinding bowl, whereby the ground material located there is advantageously crushed before it migrates outwards due to the centrifugal forces and is subjected to a further and final comminution by rolling off the pestle on the wall of the grinding bowl.
- a permanent magnet on the shaft of a drive motor under the bottom of the grinding bowl, the grinding bowl preferably being eccentrically fixed over the permanent magnet.
- the permanent magnet is replaced by an electromagnet, which has the advantage that the strength of the acting magnetic force can be regulated and the electromagnet also can be coupled with an interval switch controlling its excitation, which enables an intermittent design of the grinding forces at the bottom of the grinding bowl.
- a housing 10 preferably houses an electric motor as the drive motor 11, which can be connected to the supply network via an on / off switch 12.
- An electronic speed control 13 and a timer 14 are also provided for controlling the drive motor 11, as a result of which the grinding conditions can be set exactly.
- the drive motor 11 extends with its shaft 15 into the region of the upper housing cover, which is set up as a holder 16 for fixing the grinding bowl 17 to be placed thereon.
- a permanent magnet 19 is arranged on the shaft 15 of the drive motor 11, just below the bottom of the grinding bowl 17, which is set up to rotate with the shaft 15 of the drive motor 11.
- a grinding stock 22 is also arranged by puncturing.
- the permanent magnet 19 arranged on the shaft 15 rotates outgoing magnetic forces capture the pestle 20, which has the same shape as the permanent magnet 19, and set it in correspondingly rapid rotary movements; these rotary movements are increased if, as not shown here, the grinding bowl 17 with pestle 20 is arranged eccentrically above the permanent magnet 19.
- the grinding force exerted on the grinding stock 22 depends on the magnetic force with which the pestle 20 is pulled against the bottom of the grinding bowl 17 and on the centrifugal force caused by the rotational speed, which leads to the rolling of the pestle 20 on the outer wall of the grinding bowl 17 , this centrifugal force essentially depends on the degree of eccentricity with which the grinding bowl 17 is arranged above the rotating permanent magnet 19.
- the initially coarse ground material is comminuted at the beginning of the grinding movement at the bottom of the grinding bowl 17 by the pestle 20 drawn against it by the action of the magnetic force and then migrates outwards due to its centrifugal force, in order to move there at the edge of the grinding bowl 17 due to the rolling of the Pistills 20 to be subjected to a further comminution.
- Replacing the grinding bowl 17 after the grinding process has ended is particularly simplified in the exemplary embodiment shown, since only the quick-release device 21 has to be actuated in order to remove the grinding bowl 17 from the mortar mill and to be able to replace it with another, appropriately prepared grinding bowl.
- an electromagnet can be provided instead of the permanent magnet 19, which advantageously has a stepless regulation of the pestle 20 acting driving and tightening forces possible.
- the mortar mill designed according to the invention can be used particularly well in the laboratories in order to achieve a corresponding degree of fineness of the ground material, because both the handling of the mortar mill according to the invention and its grinding behavior are significantly improved by the invention.
- the mill is built less complex and is therefore characterized by high operational reliability.

Abstract
Les broyeurs à pilon, surtout ceux destinés à l'usage des laboratoires, et qui sont munis d'un récipient pour le matériau de broyage, et dans lesquels est disposé un pilon de façon mobile pour servir d'élément de broyage, présentant l'inconvénient qu'il est impossible de disposer d'un système entièrement fermé étant donné que le pilon est maintenu et guidé pendant le processus de broyage sur un dispositif de maintien qui s'étend à travers le couvercle du récipient de broyage. Pour résoudre ce problème, l'on envisage la transmission au pilon (20) de la force d'entraînement par un moyen magnétique, le récipient de broyage (17) restant immobile.
