The invention relates to fodder production and can be used in the agriculture, meat, food and feed industry.

A device for grinding and drying raw materials (AS USSR № 1757579, CL А23К 1/10, А01Р 29/00, 1992), which consists of a body divided by partitions into sections, pipes for raw materials and drying agents, the outlet pipe is known. and connecting sections of the nozzle housing. On a horizontally positioned shaft, disks are fixedly mounted with hinged ones one after the other along a helix with their fingers. Fencing elements made in the form of dies are installed on the inner surface of the housing.

The disadvantage of this device is the retention of more solid particles of waste bone material in the grinding zone, which increases the duration of grinding.

A device for grinding and drying raw materials (AS USSR №1565399, CL А01Р 29/00, 1990), which consists of a housing with inlet pipes for raw materials and a drying agent and an outlet pipe divided by partitions into sections communicating with passage of material, and has a pipe for additional supply of the drying agent. On the horizontally located shaft of the housing with the disks and the fingers hinged on them along a helix forming a single-phase auger, and on the inner opposite sides of the housing, there are fender-mounted elements. In the receiving part of the housing, a single-step auger coil is installed on the shaft, which ensures the supply of raw materials to the crushing and drying zone.

The disadvantage of this device is overheating of fine crushed particles, caused by the lack of space for drying in a suspended vortex state, which creates additional conditions for moisture return inside the device.

A device for grinding and drying raw materials (AS USSR № 902704, cl. А23К 1/10, 1980), which is the closest technical solution for the design features and taken as a prototype, consisting of a body equipped with inlet pipes, respectively, is known. feed material and drying agent, the outlet for the dried product. Inside the housing there is a shaft with disks, which have pivotally mounted fingers with reflective blades on both sides, baffling elements located on the inner surface of the housing and adapted to prevent the ablation of crushed particles.

The disadvantage of this device is the low biological value of the finished product, due to the limited creation of weighted vortex flow for uniform distribution of temperature and humidity in the volume of the device.

The technical challenge is to develop a device for grinding and drying in the processing of waste bone material in the production of bone meal, providing high-quality, biologically valuable bone meal with a reduction in the duration of grinding and the elimination of overheating of fine crushed particles.

The technical result is to improve the quality of drying and grinding of waste bone material through drying in a suspended vortex state, which creates additional conditions for moisture return inside the device's elongated body, eliminates the retention of more solid particles of waste bone material in the grinding zone and provides high-quality, biologically valuable bone material. feed meal.

This is achieved due to the fact that in a known device for grinding and drying raw materials, including a housing with impact elements installed inside it on the shaft, baffling elements located on the inner surface of the housing, branch pipes for feeding raw materials, supplying a drying agent and output of the finished product, are proposed percussion elements rigidly mounted on the shaft, while the lateral rows of rotating percussion elements set obliquely to create a weighted vortex state of the dried and grinded particles of waste bone o the raw materials, the central rows of rotating impact elements should be installed vertically in order to eliminate the retention of more solid particles of waste bone material in the grinding zone, the input of raw materials and the drying agent should be carried out separately, and the volume of the body should be extended in order to evenly distribute temperature and humidity in the device high quality, biologically valuable bone meal.

The invention is illustrated in the drawing. The drawing shows a device for grinding and drying in the processing of waste bone material in the production of bone meal.

A device for grinding and drying during the processing of waste bone material in the production of bone meal is composed of body 1, pipe 2 for feeding raw materials, pipe 3 for supplying a drying agent, pipe 4 for the finished product, shaft 8, inclined mounted percussion elements 5, vertically installed impact elements 6, fender elements 7.

Device for grinding and drying in the processing of waste bone material in the production of bone meal flour works as follows. Pre-crushed, defatted, sterilized bone material is fed into the pipe 2 for the supply of raw materials. In the pipe 3 enters the drying agent is hot air with a temperature of 130-300 ° C. The raw material is crushed by means of 8 percussion elements 5 vertically mounted on the shaft, vertically mounted on your 8 percussion elements 6 and
