Abstract

The invention relates to devices for grinding; The goal is to increase the productivity of the grinding process. The grinder consists of a bunker, on the end walls of which windows 2 are made with regulating dampers 3. In the lower part of the bunker there is a fixed lattice frame 5, the upper surface of which is gable with slopes in the direction of the windows. The knives -6 on the frame are set in two rows at a distance from each other equal to the magnitude of the displacement of the frame, and the distance between the end walls of the lower base is equal to the double displacement amplitude. The partition 7 is installed in the lower part of the bunker and divides it in half. 3 il.

Description

The invention relates to a device for grinding bulk materials and can be used for grinding ground fertilizer and limestone flour.

The purpose of the invention is to increase the productivity of the grinding process.

FIG. 1 shows a shredder, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The grinder consists of a bunker 1 on the end walls of which windows 2 are made with regulating dampers 3. At the bottom of the bunker, on the roller supports 4, a movable lattice frame 5 is installed, the upper surface of which is made gable with slopes in the direction of the windows; 6

The lower part of the bunker is partitioned off by a partition 7, which in its lower part has the shape of a comb and enters the gaps between the plates of the grating frame 5 with its teeth. The partition on the axes 9

hinged on the side walls 10 of the hopper 1. The lattice frame 5 is connected with a crank mechanism 11.

The installation works as follows.

With the help of a loader, the hopper 1 is filled with compacted material. The reciprocating movement of the lattice frame 5 is brought in. When the lattice frame 5 is moved from left to right, the knives 6 of the left row will scour the material layer to the depth of the knife. When the knives reach the septum 7, the frame 5 will change direction of movement and will move to the left side. At the same time, the combed loosened layer of material to the height of the opening of the unloading window H 2, together with the lattice frame 5, will also move to the left and be forced out into the window beyond the limits of the bunker. At the same time, the vacant space, the beginning of the partition, as the frame moves to the left, will be filled from above with a new portion of non-loosened material. When moving

At the same time, the loosened mass from the frame 5 will be poured off, and the chopping knives 6 will, in turn, be introduced into the new batch of material, loosened and prepared for delivery. The processes on the other side of the partition 7 will be similar, only shifted by 180 ° along the crankshaft of the crank mechanism 11.

The part of the material sifted through the trellised frame 5, in the form of spills, will complement the volume of the ground mass.

Claims (1)
