Mills for grinding dry products and confectionery rolls.

For grinding dry products (sugar, coffee, spices, biscuits) there are grinders.

Grinders are divided into disc and impact grinders. In disc mills, the grinding elements are notched friction discs - burrs (drawing), and in the impact hammers.

The granulation of the ground products cannot be adjusted in impact mills. Therefore, the ground product must then be sieved through sieves.

Disc coffee grinder with dispenser (drawing) is equipped with a device for changing the granulation of the ground coffee (by advancing or moving away the burrs) and with a device for regulating the size of the dispensed portions.

A fitting attached to the grinder body is used to iron a portion of coffee. The capacity of the grinder is 50 g/min.

Similar mills are used for grinding spices (pepper, carnations, cinnamon, nutmeg).

Impact grinder (micromill) for grinding sugar (drawing) it is characterized by high efficiency and simple construction. The rotor with suspended steel plates is mounted on the horizontal shaft in the frame of the machine, the so-called. hammers. These hammers constitute the working unit of the machine. Sugar poured into the machine is picked up by a screw conveyor and moved to the hammers, which, as a result of the centrifugal force, assume a radial position and, hitting the sugar crystals, throw them with great force on the so-called. comb, installed in the cover. The ground sugar is sifted through a calibrated sieve, located at the bottom of the micro-mill.

For crushing cheese, taste, nuts, almond machines are used machines with two or three granite or steel rollers. These are the so-called. confectionery rolls (drawing).

Raw materials are poured into the charging hopper 1 fall between two crushing rollers 2 i 5. The clearance between the rollers is regulated by screws 4. The smaller the distance between the rollers, the more intense the rubbing is. The pressure of the rollers can be adjusted while the machine is running. The shredded raw material is harvested with a knife 6 with adjustable pressure 7 and poured into the container 3. At the bottom of the fuselage 8 there is a motor with a drive mechanism.
