Intermittent ball mill

Working Principle
.>This machine is a horizontal cylindrical rotating device with an outer edge gear drive and a two-chamber lattice ball mill. The material enters the first chamber of the mill evenly and spirally from the feeding device through the feeding hollow shaft. The chamber has stepped linings or corrugated linings and is filled with steel balls of different specifications. The rotation of the cylinder generates centrifugal force, which brings the steel balls to a certain height and then falls to the opposite side. The material has a pounding and grinding effect. After the material reaches coarse grinding in the first chamber, it enters the second chamber through the single-layer partition board. This chamber is equipped with a flat liner and has steel balls inside to further grind the material. The powdery material is discharged through the discharge grate plate to complete the grinding operation.
.>Structure and Classification
.>The intermittent ball mill is composed of the feeding part, the discharging part, the rotating part, the transmission part (reducer small transmission gear motor electronic control) and other main parts. The hollow shaft is lined with steel castings and is removable. The large rotary gear is hobbing using castings and has a wear-resistant lining plate inlaid in the cylinder, which has good wear resistance. The machine operates smoothly and reliably.
.>Note: Dry ball mill and wet grid ball mill can be selected according to the material and ore discharge method.
.>The classification is roughly as follows:
.>1. According to the type of grinding and upgrading, it can be divided into:
.>The ball mill medium is metal balls (steel balls or cast iron balls).
.>The medium of rod mill is steel rod.
.>Gravel mill uses gravel as the grinding medium.
.>Autogenous grinding machines rely on large pieces of ore as the grinding medium and sometimes add a small amount of steel balls.
.>2. According to the ore discharge method, it can be divided into:
.>Overflow type grinding machine, which freely overflows the slurry through the hollow journal at the ore discharge end.
.>Grid type ball mill discharges material through the holes on the grid plate installed at the discharge end.
.>Peripheral discharge type grinding machine discharges materials through the periphery of the cylinder.
.>3. According to the different shapes of the cylinder, it can be divided into:
.>Short barrel type grinding machine/D. . (It is the length of the grinding mill. D is the diameter of the grinding machine).
.>Long barrel type grinding machine/D. . When /D is, it is called a tube mill, and its interior is divided into several chambers. It is called a multi-chamber grinder and is generally used in the cement industry.
.>Conical grinding mill my country has stopped manufacturing this type of grinding mill.
