In the developed feed distribution system, it is ensured that the grain transferred into the roller or the semi-milled grain is distributed equally between the grinding rolls along the entire grinding line. Thus, the accumulations that may occur between the grinding rolls and the deformations that will occur due to this are prevented.

Description

ROLLER MILL FEED DISTRIBUTION SYSTEM
TECHNICAL FIELD
The invention relates to the roller mill feed distribution system, which ensures that the grain or semi-milled grain products fed into the grinding rolls in the roller mills are evenly distributed along the entire grinding length between the rollers.
PRIOR ART
The product to be ground is transferred to the mill rollers with the help of flow pipes. The grinding process is carried out by transferring the raw grain or semi-milled grains, taken into the roller mill, between the grinding rolls by means of feeding rolls. Meanwhile, the homogeneous distribution of the product between the rollers directly affects the product quality achieved after the process. Failure to distribute the products fed to the mill roller homogeneously on the grinding rolls also causes some parts of the grinding rolls to deform. The milled products are then transferred to the next process section by pneumatic conveying systems or conveyors.
In the previous patent document EP0038054, a method is mentioned in roller mills, where the grinding material is fed from the middle to the relevant grinding pass inlet, and accumulated and distributed to the outside by gravity when necessary with the help of a pallet roller and conveyed to the grinding opening by means of the feed roller.
Again, in the previous document EP3572152, a method is mentioned in which the products ready to be ground are fed to the mill roller from a single point and transferred into the grinding rolls with the help of a distribution conveyor. BRIEF DESCRIPTION OF THE INVENTION
The roller mill feed distribution system, which is the subject of the invention, has been developed for the grinding rolls used in grain grinding mills with the aim of spreading the grains or semi-milled grains equally between the grinding rolls and along the entire grinding line.
In the feed distribution system developed, it is ensured that the grain or semi-milled grain transferred into the roller mill is distributed equally between the grinding rolls along the entire grinding line. Thus, the accumulations that may occur between the grinding rolls and the deformations that will occur due to this are prevented.
In the feed distribution system developed, the flow rate of the grain or semi-milled grain product fed into the roller can be selected according to the grain size. In this way, a smooth material flow can also be obtained between the grinding rolls for different sized products to be ground.
In the feed distribution system developed, a regular product flow and efficient grinding are obtained continuously between the grinding rolls along the entire grinding line by ensuring product flow regulation in different regions.

DETAILED DESCRIPTION OF THE INVENTION
Roller mill feed distribution system, which is the subject of the invention, contains the parts and sections of the expansion chamber (4), on which the grain or semi-milled grain product coming from the feeding nozzle (1 ) is transferred, the vibration motor (2) that provides the movement of the expansion chamber (4), the connection plate (3) that connects the vibration motor (2) to the expansion chamber, the flow adjustment gate (5) that restricts the flow of the product accumulating in the expansion chamber (4), the passage opening (6) where the product flow is realized between the flow adjustment screen (5) and the expansion chamber (4), the flow plate (7) that provides the transfers of the product that passed through the passage opening (6) to the grinding rolls (8).
The vibration motor (2) developed in the roller mill feed distribution system, which is the subject of the invention, is the part that provides the vibrational motion of the expansion chamber (4) so that the grain or semi-milled grain product is spread in the expansion chamber (4). The vibration motor (2) is the part that provides the vibrational motion of the expansion chamber (4) by being connected to the expansion chamber (4) via the connection plate (3).
The connection plate (3) developed in the roll mill feed distribution system, which is the subject of the invention, is the part that enables the vibration motor (2) to be connected to the expansion chamber (4).

Expansion chamber (4) is the part with vibration movement driven by the vibration motor (2) to ensure the spread of the product fed into it. The flow adjustment screen (5) developed in the roller mill feed distribution system, which is the subject of the invention, prevents the grain or semi-milled grain product transferred into and distributed in the expansion chamber (4) coming out uncontrollably from inside the expansion chamber (4) across the expansion chamber (4), thus regulates the product flow as desired. The flow adjustment screen (5) is a movable part that allows the distance between it and the surface of the expansion chamber (4) to be changed.
The passage opening (6) developed in the roller mill feed distribution system, which is the subject of the invention, is the section where product passage is provided between the expansion chamber (4) and the flow adjustment screen (5). The passage opening (6) is a section where the product passage clearance can be changed depending on the movable structure of the flow adjustment screen (5) on the expansion chamber (4). Thus, the amount and speed of the product fed into the grinding rolls can be adjusted as desired.
The flow plate (7) developed in the roller mill feed distribution system, which is the subject of the invention, is the part, on to which the product accumulated in the expansion chamber (4) and passing from the passage opening (6) formed between the flow adjustment screen (5) and expansion chamber (4) is transferred, and contains at least one flow duct (7.1 ). The flow plate (7) is preferably designed to allow product flow across the grinding rolls (8). The flow duct (7.1) formed on the flow plate (7) is the section formed in a geometrical structure that will enable the grains or semi-milled grains to be positioned in the grinding space between the grinding cylinders (8) in such a way that they cannot overlap each other, and will contain enough space to accommodate just one particle concurrently. The flow duct (7.1 ) formed on the flow plate (7) is the section where preferably surface improvement is made by grinding, varnishing, and polishing processes.
With the roller mill feed distribution system, which is the subject of the invention, grinding regularity is ensured by taking the grains or semi-milled grains into the grinding cavity collinearly and preferably parallel to each other. Again, grinding efficiency is increased by taking the grains or semi-milled grains into the grinding cavity collinearly and preferably parallel to each other, the separation of the husk endosperm of the grains is facilitated by taking the grains or semi-milled grains into the milling cavity perpendicular to the grinding cavity and preferably parallel to each other. Grinding can be done equally in the entire grinding length by taking the grains or semi-milled grains into the grinding cavity collinearly and preferably parallel to each other. The service life of the long- lasting grinding rollers (8) is extended further, thanks to the fact that the mechanical abrasions are the same across the entire grinding length when the grains or semi-milled grains are taken into the grinding cavity collinearly and preferably parallel to each other. It is ensured that the mechanical stresses are equal in the entire grinding length by taking the grains or semi-milled grains into the grinding cavity collinearly and preferably parallel to each other. It is ensured that the thermal stresses are equal in the entire grinding length by taking the grains or semi-milled grains into the grinding cavity collinearly and preferably parallel to each other. It is ensured that the product quality is increased by taking the grains or semi-milled grains into the grinding cavity collinearly and preferably parallel to each other. It is ensured that all the products that pass through the grinding cavity are ground equally and the workload of the other grinding rollers in the process is reduced by taking the grains or semi-milled grains into the grinding cavity collinearly and preferably parallel to each other.
