(54) GRINDER OF BULK MATERIALS

I

The invention relates to a device for grinding materials and can be applied in the food, agricultural and other industries.

Known hammer crusher, including boot device, body, rotor with hammers, and the drum is made perforated, and the rotor is conical I.

Such a structure is complex and ineffective.

The closest to the invention technical solution of the known is a grinder of bulk materials, mainly grain feed, containing a cylindrical body, on the inner surface of which partitions are installed, a rotor with hammers, loading and unloading devices 2.

The purpose of the invention is to increase the efficiency of the material grinding process.

This goal is achieved by the fact that the proposed grinder of bulk materials, mainly grain feeds, comprising a cylindrical body, on the inner surface of which partitions are installed, a rotor with hammers, loading and unloading devices, is provided with sawtooth fender elements, and partitions are made in the form of blades and are installed along the length housing, moreover, the fencing elements are located between the partitions, while the right angle of each tooth of the fender elements is directed toward the loading bin, and ing angle at the base of the tooth is made larger than the angle of repose of the material to be ground.

The baffle elements are shifted relative to each other by half the schaga and are higher in height than the height of the blades.

FIG. 1 depicts the described shredder bulk materials, a general view; in fig. 2 - scan of the crusher body; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 2; in fig. 5 shows a section B-B in FIG. 2

Claims (2)

The shredder of bulk materials, mainly grain feeds, contains a cylindrical rotating body with a rotary working body 2 of hammer type, on the inner surface of which along its length there are baffles, made in the form of blades 3 at an angle to the generator and radius of the rotor, and together with the inner surface of the body they form pacifying pockets in which the rebounded material temporarily, after the first impact with hammers, stops. In the space between the blades 3, sawtooth fender elements are installed, you are 4, the right angle at the base of the tooth of which is directed toward the loading hopper 5, and the acute angle at the base of the tooth is larger than the angle of repose of the material to be ground. In addition, these grids are mixed relative to each other by half a step, and their height is less than the height of the blades. The casing is rotated from the electric motor b through the variator (not shown) and the worm gear 7, and the rotary working body through the clutch 8. There is a trie-type discharge device 9 for selecting the finished product. The grinder works as follows. The grain from the loading hopper 5 freely falls into the inter-blade space on the sawtooth chipping elements 4 and collects in the cavity of the first tooth of it, rolling down over it (zone a). Rotating together with the grinder body, the grain from zone a moves to zone b, from where it is sent under the blows of the hammers of the rotary working body 2 and experiences initial destruction. After that, the particles of the material are again poured onto the fender elements 4 into zone a, but already into the cavity of the next tooth, due to the displacement of the fender elements relative to each other by half a step. Further, the process is repeated, but the material with each turn of the body. moves one tooth to the unloaded device 9 and after final grinding, fills the container. The grind size can be adjusted during operation of the shredder by changing the speed of rotation of its body using a variator (not shown). At low body speeds, the product is smaller, since its residence time inside the chamber is longer, and at higher speeds, the product is larger. The use of the specified grinder of bulk materials allows to increase the efficiency of the material grinding process, as well as reduce the metal consumption of the structure. Claim 1. Grinder of bulk materials, mainly grain feeds, comprising a cylindrical body, on the inner surface of which partitions are installed, a rotor with hammers, loading and unloading devices, characterized in that, in order to increase the efficiency of the material grinding process, the grinder is provided with sawtooth-shaped baffle elements , and the partitions are made in the form of blades and mounted along the length of the body, with the baffle elements located between the partitions, with the straight corner l of each tooth of the baffle elements is directed towards the loading hopper, and the acute angle at the base of the tooth is made greater than the angle of repose of the material to be ground. 2. Grinder according to claim 1, characterized in that the baffle elements are mixed relative to each other by half a step and are made in height less than the height of the blades.
