Translation of "Kollergang" in English

What is considered particularly as a vertical roller mill is an air-swept mill or an edge mill.

Production started after this, with the strength of one man and a pan mill.

The initial materials were ground dry and were mixed in the pan grinder for some hours with addition of mixing water.

Alternatively, the pellets of the binder, including embedded swelling additive, were filled into the pan grinder.

Edge mill (approx. from 1920) used to grind the clay coming from the adjacent pit.

The use of a hydrophobic filler, which has been rendered hydrophobic in a fluidized bed, pug mill machine or stirred ball mill, etc. such as disclosed in U.S. Pat. No. 3,868,345 to Kratel, or in corresponding DE-OS 2,211,377 in compositions which are curable to form elastomers, is impossible in many cases, since the properties of the products prepared therefrom differ from those of the products produced in the in-situ process.

In a mixer, boehmite (Versal® 250, obtained from Euro Support, Amsterdam) was moistened with water, intensively milled in a pan mill until the mass was readily moldable and subsequently extruded to produce 3 mm extrudates.

In a possibly advantageous embodiment, the preparation of the catalyst precursor may be carried out by intimately blending the said precursor compounds of the active composition and the promotor and any sulfur and/or phosphorus to be added, as undissolved compounds, with the support or support precursor in suitable apparatus, for example a kneader or pug mill, in which case auxiliaries such as polyethylene or butylene glycols can be added.

DE-B-12 21 893 describes the production of a coated printing paper in which starch is rendered partially cold-soluble by mechanical treatment in a pug mill so that when drying is effected subsequent to the coating process it will still be dissolved by the evaporating water of the coating compound and, in dissolved or gelatinized form, contributes, as binder, to the fixation of the pigments, e.g., chalk, in a manner known per se.

The press cake resulting from this mechanical predrying is then broken up to give a free-flowing product in a manner known per se, advantageously in a mill and subsequently in a compactor, comprising crushing rollers with die (baseplate with holes).

The pieces of press cake from the mill fall into a compactor (crushing rollers with die, manufacturer: Kahl, Hamburg) where they are pressed to give pellets with a length of 3 mm and a diameter of 2 mm.

Suitable embodiments of the process according to the invention consist in carrying out the mechanical compaction process at moderate pressures in a flat-cavity press (edge mill), a hydraulic press or a roll press.

In accordance with the methods already described, the spherical iron oxide can be obtained by consolidation in the pug mill or by other methods accessible to the expert without inventive effort.

The powder so heated was then introduced into a machine which consisted, in a manner similar to that of an edge runner mixer, of a flat circular plate having a diameter of 450 mm, on which were rolling four rolls the axes of which were parallel to the plate.

DE 295 563 further discloses an edge mill having a driven table and an edge runner which is retained by means of a pivot lever.

The boehmite is treated with the peptizing agent by moistening it with the peptizing agent and mixing it intensively, for example in a kneader, mixer or edge-runner mill.

The granulate may be prepared from a mass that is homogenized or chemically combined at a high temperature in a kneader or by pressing the individual components at a low temperature (edge mill, orifice plate).

DE 201 06 177 U1 relates to an edge mill with an additional drive which has a direct torque adjustment system.

If particularly uniform or low particle sizes are desired, in order, for example, to enhance the fluidity of the salt (P) of the invention or to ensure a better distribution in the building material, however, it may be advantageous to subject the solid isolating after step 4 to mechanical communition in an additional step (by grinding in an edge runner mill or a ball mill, for example) and, optionally, to classify using screens or pneumatic classification.

Suitable grinding methods for this purpose are, in particular, those of dry grinding or also grinding in aqueous suspension, for example using a pan grinder, a pin mill or a ball mill.

Since an edge mill and an air-swept mill are sufficiently known from the prior art, further details are therefore not dealt with.

The comminuted ingredients were intimately mixed in an edge runner mill and subsequently homogenized in an extruder at up to 130° C. maximum.

The comminuted ingredients—powder coating curing agent, catalysts, and leveling agent—were intimately mixed in an edge runner mill, and then homogenized in an extruder at 130° C. maximum temperature.

The “salt grinding method” produces a colorant by traditional manner in that the crude is reduced in size in the presence of a large amount of micronized salt and glycols, if needed under addition of additives by mechanical treatment in a chaser mill or in a kneader unit.
