DESCRIPTION

The stone roller mill (piece 1/2 table), with elastomer core (piece B table 1/2), is used to grind barley, wheat, wheat, spices and various cereals, for the production of beer, unlike other models in with metal rollers, the stone rollers (piece Atavola 1/2) have the ability to increase friction by producing a higher quantity of crushed grains and the elastomer core <pieceBtable 1/2) to allow to dampen vibrations on the rollers, reducing the risk of roll breakage and avoiding the production of flour. As the grains are only crushed so that the epicarp remains attached without producing any flour. This invention is suitable for all producers of beer, whiskey, or products that need this type of grinding. Looking at the two attached drawing boards, the mill is characterized by the fact that it has rollers (pieces R1R2 table 2/2) having a central metal shaft (piece Ctavola 1/2), an elastomer (piece Btavola 1/2) and the outermost part in stone (piece Atavola 1/2), at the two ends of each roller we have the two

DESCRIPTION

shaft parts where the relative bearings will be fixed (pieces D table 1/2) and then the plates (pieces E table 1/2) will be positioned with a hole equal to the diameter of the bearing, so as to allow a precise rotation on the axis of the roller, then by means of the screws (piece V table 1/2) the plates will be mounted (pieces Ftavola 1/2) having the central holes with a diameter slightly greater than the diameter of the shaft (piece C table 1/2) in order to avoid a rubbing of the two pieces, but with a diameter smaller than the bearing (piece D table 1/2) so as not to have a displacement on the shaft axis, note the detail X (table 1/2), a shaft stop so that the two roller surfaces (piece A and Btavola 1/2) cannot come into contact with the plate (piece Etavola1 / 2) avoiding rubbing or total locking of the roller. The assembly is mirrored unlike one end where a gear (piece G table 1/2 and 2/2) will be fixed on the shaft (piece C table 1/2), while the other end of the shaft (piece C table 1/2) can be finished so as to

DESCRIPTION

have a square section (piece H table 2/2) or half-moon (piece W table 2/2) for coupling to a motor.

The assembly of all these parts is to mount a pair of rollers (pieces Rl R2 table 2/2), they will be assembled by means of the screws (piece Stavola 2/2) on the two plates called L (table 2/2) having four holes for fixing, the holes are different, unlike the N (table2 / 2) the holes M (table2 / 2) have a slot so as to be able to translate the roller Rl (table 2/2) to the left moving it away from the roller R2 ( table 2/2), thanks to this we could adjust the grinding according to the grain size. Then we will pour the grain between the two rollers in zone P (table 2/2), depending on where we will mount the motor if we should turn the motor clockwise or counterclockwise to drag the grain from top to bottom.

Claims (1)

CLAIMS [1] Mill characterized by cylindrical stone rollers (piece A table 1/2) drilled along the axis with an elastomer core (piece B table 1/2) comprising central shafts for transmitting the rotary motion in metal (piece C table1 / 2) and by two gears (pieces G table 1/2 and 2/2) mounted at the end of the two rollers. [2] Stone rollers according to claim 1 characterized in that they can be made with any type of stone, (piece A plate 1/2). [3] Stone rollers according to claim 1 can have grooves, lines, chemical treatments, mechanical treatments on the external surface to increase the friction (piece A table 1/2). [4] Stone rollers (piece A table 1/2) according to claim 1 characterized by the fact that they may or may not have an elastomer core (piece B table 1/2) or a basically elastic material. CLAIMS [5] Elastomer core (piece B table 1/2) according to claims 1 and 4 characterized by the fact that it serves to anchor the stone cylinder (piece A table 1/2) with the transmission shaft (piece Ctavola1 / 2) . [6] Core in elastomer (piece Btavola 1/2) according to claims 1,4,5, characterized in that it serves to attenuate the rigidity of the rollers (piece A table 1/2) while preserving their breakage. [7] Elastomer core (piece B table 1/2) according to claims 1,4,5,6, characterized in that it serves to avoid the production of flour during the grinding phase. [8] Stone rollers (piece A plate 1/2) according to claim 1,2,3, characterized by the fact that thanks to the type of grip on the grain, they contribute to producing less flour.
