Description

The invention relates to agriculture, in particular to methods for producing grass meal granules.

According to the main author. St. No. 347051 discloses a method for the production of grass flour pellets, which includes drying and grinding, grass mass, dosing, moistening in suspension and pressing grass flour, and the grass flour is moistened with heat carrier that was used for drying grass fij .

The known method has the disadvantage that in the crusher, cyclones and flour pipelines a fire-and-explosion-hazardous mixture of grass J1 and air is formed. The occurrence of fires leads to a forced shutdown of the process, and explosions to accidents.

The purpose of the invention is to prevent

20 ignition of grass meal during its production.

The goal is achieved by the fact that, according to the method of production of granules from grass meal, the grinding of grass mass is carried out in the heat transfer medium used for drying the grass mass.

The drawing shows schematically an assembly in which the granule production method is implemented.

The unit includes a loading tray 30, a drying drum 2, a furnace 3, cyclones 4, 5 and 6, a crusher 7, (З-load neck 8, air ducts 9 10 10 and 11, granulator 12, inlet part 13 crushers and damper regulator 14.

The process is carried out in the following manner.

A grass pit is fed through a loading chute, a conveyor belt and a transport conveyor into a drying drum 2, where it is dried with a hot stream of combustion products coming from the firebox 3. Next, dried herbs for chopping are delivered to the crusher through the inlet part 13, where it is crushed. At the same time at the entrance of the crusher enters through the duct 11 spent on the drying fluid. The carrier moves due to the pressure difference at the ends of the duct 11 — the pressure at the outlet of the cyclone fan 4 is greater than at the inlet of the fan of the cyclone 5, which is the crusher inlet. By feeding the heat-transfer medium into the crusher, the grinding of the ds1 chop of flour and its subsequent transportation to the cyclone 5 takes place in an atmosphere with low oxygen content. The further implementation of the technological process takes place according to the well known scbme, according to which the flour is transported to the granulation also by coolant.

This method of producing granules from grass flour helps to prevent the ignition of grass flour by grinding the grass from the ground mass in the heat carrier medium, which was used to dry the grass mass.
