Wheat Roller Flour Mill

Flour Roller Mill is designed to grind grain and other loose food products. Depending on the processing purpose, it is also available with fluted or smooth iron grinding rolls with a chilled surface.

The mill is seperated technologically and kinematically into two completely independent halves. The main working members of the mill are two pairs of diagonal grinding rolls. The rolls of each pair rotate in opposite direction with different peripheral velocities.The degree of breaking of the product by the rolls depends on their speed ratio (differential) and the magnitude of the relative velocity of the fast grinding roll.

The roll flutes are the fine longitudinal grooves of corresponding profile and size , made on the surface of the rolls with a small slope in respect to the generating line , owing to which the efficient performance of the rolls is raised.

The product is fed to the grinding rolls in a thin uniform strip with the aid of a roll type feed mechanism with an adjusting feed plate which ensures automatic control of mill output.

One of each pair of rolls is mounted in bearings that are displaced with the aid of two special mechanism , one of which permits he parallel alignment of the rolls. and the other is used for subsequent decrease or increase of the clearance between the rolls.

The grinding rolls are set in the working position by means of an eccentric engagement mechanism. The rolls are being engaged and disengaged without changing the previously adjusted roll clearance.

Foreign objects of a size exceeding that of the handled grain , getting accidentally between the grinding rolls are passed in between them with the aid of spring-type shock absorbers fitted in the engagement mechanism.

The roll flutes are cleaned from disintegerated particles of the handled product with the air of brushes.

Each half of the mill is driven from an electric motor through a v-belt or flat-belt transmission. The second roll receives rotation from the first roll through an interroll drive.

To prevent runout of the rolls in the course of grinding , they are made of solid construction.

The rolls rotate in the roller bearings.

To prevent condensation of the moisture , warm air is evacuated from the mill by a special aspiration system.

Grinding rolls perform with a clearance adjustable within 0.15 to 1.75mm. In the process of product disintegration there appears between the rolls a pressure exceeding the weight of a roll. Upon interruption of feed of the handled product one of the rolls may come into contact with the other.
