Übersetzung für "Mechanische zerkleinerung" in Englisch

After solidification of the resin melt, it was mechanically comminuted.

By this characteristic the mechanical comminution preceding the biodegradation is facilitated.

This, too, facilitates the mechanical comminution of the tobacco smoke filter element preceding the biodegradation.

As an option, the fineness can be increased by mechanical pulverisation.

Mechanical comminution in the course of drying is disadvantageous.

Alternatively, nearly analog cleaning may also be done by mechanical crushing.

The mechanical comminution may also be performed by all known comminution methods.

The tissue particles are prepared by the mechanical comminution of the tissue material removed and, if necessary, by a following enzymatic digestion.

As a result of a corresponding mechanical comminution it is ensured that the resulting tissue particles have a narrow size distribution.

Firstly, owing to the wide gap 24, the mechanical breakdown of solid matter would no longer be ensured.

The particle size is adjusted after stripping of the metal films from the carrier sheet, through mechanical comminuting of the film fragments.

In this way, particles of the desired size can also be produced without subsequent mechanical crushing.

Digestion is initiated by the mechanical processes of crushing, transport and mixing.

Mechanical weathering is the cause of the disintegration of rocks.

The types of copper suitable for carrying out the Rochow synthesis are prepared, inter alia, by electrolysis of a Cu salt solution, atomization of a Cu melt, mechanical comminution of coarse lumps of Cu or by precipitation of Cu from Cu salt solutions using appropriate reducing agents, it also being possible for baser metals, such as, for example, iron, to be used for the reduction of the copper ions (so-called cementation of copper).

Since the plexus filaments have a high extensibility, this mechanical comminution can be carried out only with a high energy consumption.

The yield is only around 80% and is unsuitable for hydrolysis without mechanical size-reduction.

The fibers themselves may be produced by dry or wet spinning processes, by coagulation processes, by fibrillation or electrostatic spraying or by mechanical size reduction, such as cutting, splitting, grinding, fibrillation.

In another embodiment of the invention, the particulate catalyst material is mechanically size-reduced after activation and stabilization.

Suitable bismuth metal powders are either obtained by mechanical comminution of bismuth bars in ball mills or mortar mills or by spraying a bismuth melt into water, it being possible for the portion with the preferred grainsize of <100 ?m to be separated off by screening.

According to another known process, the cost of the mechanical reduction of the size of the elements or of their graphite shells is saved, and the process is simplified, by completely reducing the intact fuel elements to ashes by burning in flowing oxygen at a temperature from 600° to about 1600° C. (e.g. at 1200° C.), as described in DE-OS No. 1 464 647, or subjecting the fuel elements to a complete gasification of graphite into CO2 gas after the addition of catalysts at above about 1000° C. or below 900° C. (e.g. at 850° C.) according to the choice of catalysts, as described in DE-OS No. 2 809 686.

A process for the production of a metal or metal alloy powder with flake-shaped particles comprises mechanically crushing a ductile starting material.

What is claimed is: A process for the production of a metal powder having flake-like particles comprising mechanically grinding a ductile starting material and putting the material into flake form, wherein the starting material includes a foreign substance as an intermediate substance which at the temperatures occurring in the flake-forming process occurs substantially only at the boundary surfaces of the crystallites of the starting material, in order thereby to improve the crushability of the starting material.

Commercially available powders which have been produced, for example, by mechanical comminution of copper or by atomization of a Cu melt can be used as starting substances.

Mechanical comminution is preferably effected in kneaders, ball mills, dispergators, bead mills, sand mills or attrition mills.

Thus, it has proven to be advantageous if the mechanical comminution of the batteries or of the sets of cells takes place under an atmosphere of water vapor or under inert gas.

For carrying out magnetic separation, it is advantageous to appropriately disintegrage the slag, mechanical disintegration to particle sizes smaller than 5 cm being sufficient, in principle.
