Abstract

Device for dividing a scab in individual briquettes, characterized in that in a housing (1) a Loswalze (2) and a hard roller (3) are arranged and so form a defined crushing gap (4) that the hard roller (3) via a drive (5) has that the Loswalze (2) is unpowered and is set in rotation from the in the crushing gap (4) that the Loswalze (2) is in operative connection with a Brechspaltverstelleinrichtung (6) with flexible suspension that the hard roller (3) has a strip-like profiling in the axial direction, while the Loswalze (2) is profiled like a disk in the radial direction, and that an angle-adjustable feed chute (9) for the scoop with alignment with the fixed roller (3) is arranged.

Description

The Invention relates to a device, namely a two-roll crusher, for dividing a scab in individual briquettes.

State of the art

As is known, are roller presses, especially two-roll presses, for the production of slugs from bulk materials, for example Lignite, suitable and extensive in practical use.

In two-roll machines, often only one of the two rolls is connected to a rotary drive. The other roller is driven by the material in the press nip. Such an embodiment is for example in the DE 38 34 425 described.

In analogously, two-roll crushers are constructed.

In The patent literature can be found methods and corresponding apparative Means for compacting and piecing fine-grained Pressed material.

In a method according to DE 2 324 695 the feed material is pressed by means of a two-roll press into a rag or plate which may have local thickening. The scoop is then crushed in a crusher into pieces of irregular grain size. As a crusher, a spiked roller crusher is preferably proposed.

To DE 25 14 703 leave the slugs the roller press on an inclined plane at the end of a crusher is arranged. The crusher contains several crushing rollers with impact plates, which separate individual briquettes depending on the advance of the scapula. In a further method according to DD 247 026 The Schülpe, here in the form of a compacted and provided with predetermined breaking points band of iron filings, subjected to a bending stress and thus brought to the defined breaking.

at the known technologies must either the slugs certain design features, for example, predetermined breaking points have or they are due to high process costs or considerable equipment Expenses marked.

The Effectiveness is u. a. also because of the breaking off high proportion of fine grain often restricted. Furthermore The dimensions of the briquettes are often irregular.

task

On The reason of the disadvantages of the prior art is a suitable Crushers are offered, with the slugs defined in Single briquettes can be broken in a continuous process, and with a low fines content.

At the scabs themselves are no special requirements posed.

Subject of the invention

The Solution of the problem is specified in the protection claim 1.

The Subordinate claims include expedient Configurations.

According to the invention the scapula at an oblique angle to the sphere of action the driven strip-like profiled crushing roller of a two-roll crusher supplied, detected by the attached strip profile and Pre-fractured by bending stress, namely linear transverse to the direction of movement of the scapula at defined intervals in accordance with the rolling speed in accordance with the Movement progress of the scapula. The detected strip segment the scapula is immediately and almost simultaneously against pressed the radially profiled Loswalze the two-roll crusher and promoted in the crushing gap.

Directly in the crushing gap is a punk-shaped flexible compressive stress.

The Pressure points are spaced from one another in a row. For this purpose, the Loswalze is in compliance with intervals occupied with disc profiles.

Consequently the scapula is in two levels, first in horizontal stripes and then broken into single briquettes.

The Single briquettes have substantially the same dimensions in permissible Tolerances. The resulting fine grain content is compared to known Procedures and devices significantly reduced.

embodiment

in the The following embodiment of the invention Hand of a two-roll crusher, namely a slug breaker for lignite for the manufacture of individual briquettes with defined Dimensions, explained in more detail with reference to drawings.

1 shows the slug press sketchy in the plan view.

2 is a side view of the same ones.

in the The example chosen is approximately 340 mm wide endless roller press rams crushed into briquettes with the dimensions of about 40 × 50 mm.

To is provided, at least one coming from a press sling band slipping on a slippery plane to a slug breaker. In this the Schülpenband of an axially profiled driven hard roller recorded, pre-broken and against a radial profiled Loswalze pressed, causing the refraction in two levels is realized.

To has a device according to the invention, namely a slug breaker, the characteristics given below on.

In a housing 1 is a Loswalze 2 and a hard roller 3 arranged so that a crushing gap 4 is formed. While the hard roller 3 via a drive 5 has, becomes the Loswalze 2 from the crushing gap 4 driven Schülpe. In addition, the Loswalze is 2 in operative connection with a Brechspaltverstelleinrichtung 6 with flexible suspension.

The hard roller 3 is circumferentially longitudinal with spaced strip profiles 7 provided, executed as edgewise with spaced apart welded and coated flat steel strip.

The Loswalze 2 is equipped in an analogous way, but with disc profiles 8th in the radial direction. The individual discs are also armored.

Finally, there is an angle-adjustable task chute 9 for the scab with orientation on the hard roller 3 arranged.
