DE19916800C2 - Device for comminuting preferably plastic masses, in particular moist clay, and hard materials - Google Patents

Description

According to the preamble of claim 1, the invention relates to a device for Crushing plastic masses, in particular of damp clay, and of hard materials, with one Filling hopper, a crushing room located underneath, one arranged at the shredding room to a horizontal Axis driven tool in the form of a single Crushing tools equipped roller-like rotor and one back and forth in front of the rotor in the shredding room movable slider. Plastic materials are preferred crushed.

Such a device is already known from DE 297 08 328 U1 known. Here the top edge of the hopper is in height a surface or ramp accessible by truck, wherein the filling opening of the hopper is one of the width the truck has adapted dimensions and above the slider another, in the upper part of the shredding room movable slide is provided.

However, this device has the disadvantage that the upper Slider not for feeding material, but for loosening of material is provided. Thus, the return stroke creates the lower slide, as in other known devices without an upper slider, an idle phase in which no Material is crushed.

The invention is therefore based on the object To create device of the specified type, the one continuous material supply guaranteed.

This object is achieved by the Characteristic features of claim 1 solved.

Appropriate developments of the invention are in the Subclaims marked.

In the device according to the invention shared and alternately working slide one continuous material supply guaranteed. The upper Slider can also be provided to loosen the material his.

An embodiment of the invention is in the drawing shown. It shows

Fig. 1 shows schematically a top view of the device according to the invention with divided lower slide and

Fig. 2 shows schematically a side view of the device with upper and lower slide.

The apparatus 1 for shredding preferably plastic materials, in particular of damp clay, and of hard materials sitting on a supporting frame 2 and comprises a hopper 3, a arranged underneath shredding chamber 4, a valve disposed in the crushing chamber 4, rotatably drivable about a horizontal axis tool in the form of a with individual comminuting tools fitted on roller-type rotor 5, and a front of the rotor 5 to the crushing chamber 4 reciprocable slide 6, which presses the material to be ground 7 (Fig. 2) against the rotor 5. The rotor 5 is equipped in the usual way with exchangeable shredding tools (not shown) and is driven in rotation by an electric drive 8 about a horizontal axis 9 .

The material 7 to be shredded (see FIG. 2) normally slips into the shredding chamber 4 and is pushed there by the slide 6 to the rotor 5 . In order to achieve a continuous supply of material, the slide 6 is formed in two parts over its width which essentially corresponds to that of the rotor 5 . Both parts 10 , 11 of the slide 6 alternately perform feed or return stroke movements.

When the clay is moist, it can occasionally happen that the material 7 compresses in the hopper 3 . In order to prevent this and to loosen the material, a further slide 12 can be arranged directly above the slide 6 . The further slide 12 can be moved back and forth in the upper region of the comminution space 4 .

The upper slide 12 can also be formed in two parts over its width which essentially corresponds to the rotor 5 . Both parts (not shown) of the slide 12 alternately perform feed or return stroke movements to one another and to the lower slide 6 .

Both slides 6 and 12 are guided linearly via rollers (not shown).

The shredded material can (not shown) to be further processed become.

Claims (4)
