Description

Verfahren zur Herstellung von Schleifscheiben aus Bauxit. Schleifscheiben stellt man seit Jahren aus Naturprodukten, wie Naxosschmirgel und Karborundurn, ferner aus künstlichem Korund, SogenanntemElektrokorund, her. Dieser Elektrokorund wird aus Bauxit gewonnen, indem Bauxit auf elektrischem Wege geschmolzen wird. Dieses Produkt wird dann vorwiegend zu Schleifscheiben verarbeitet.Process for the production of grinding wheels from bauxite. Grinding wheels has been made from natural products such as Naxos emery and carborundum for years, also made of artificial corundum, so-called electric corundum. This corundum is obtained from bauxite by electrically melting bauxite. This The product is then mainly processed into grinding wheels.

Nach der Erfindung wird vorgeschlagen, aus geeigneten Bauxitablagerungen Schleifscheiben herzustellen unter Ausschaltung der vorherigen Bearbeitung des Bauxits im elektrischen Ofen. Hierzu eignet sich hauptsächlich oberhessischer Bauxit wegen der Eigenart seiner Gewinnung, bei welcher ein Waschen des Gesteins stattfindet. Die hierbei erhaltenen Rückstände bestehen in der Hauptsache aus Bauxit von gleichmäßiger Korngröße, welcher ausgesucht und wiederum gesiebt wird und hiernach sich ohne weiteres zur Herstellung- von Schleifscheiben eignet, wie sie in technischen Betrieben benötigt werden.According to the invention it is proposed to use suitable bauxite deposits Manufacture grinding wheels by eliminating the previous processing of the bauxite in the electric oven. Upper Hessian bauxite is mainly suitable for this purpose the peculiarity of its extraction, in which a washing of the rock takes place. The residues obtained in this way consist mainly of bauxite of a more uniform type Grain size, which is selected and again sieved and then easily changes Suitable for the production of grinding wheels, as required in technical companies will.

Der gewonnene -Bauxit wird mit fein pulverisiertem Glas, Ton oder Feldspat und einem Zusatz von Wasserglas gründlich vermengt und diese Masse in Preßformen zu beliebigen verlangten Größen gepreßt, hierauf in bekannter Weise getrocknet und bei Weißgluthitze gebrannt.The obtained bauxite is made with finely powdered glass, clay or Feldspar and an addition of water glass are thoroughly mixed and this mass in compression molds pressed to any required size, then dried in a known manner and Fired in white heat.

Auf diesem Wege hergestellte Schleifscheiben sind von vorzüglicher B:eschaffenheitund haben sich außerordentlich bewährt.Grinding wheels made in this way are excellent B: quality and have proven themselves extremely well.
