Product Details

Round Disc Grinder

I.Usage

The product is mainly used for medium hardness ore crushing, is one of the main instruments equiped for laboratories in the fields of metallurgy, geologic, mining, construction materials, chemical, etc..

II.Structure and Principle

The machine mainly comprises main body, base, mainshaft, movable disc, fixed disc, end cover and receiving hopper. The force is transfered to the groove pulley through V belt and propels the mainshaft rotation, then relative movement is generated between the movable disc and fixed disc, and crush the ore. The size of the crushed ore can be controlled by adjusting hand wheel, mainshaft to get suitable distance between the two discs.

The main body is installed on the base, its transmission parts includes transmission shaft, bearing, movable disc, pulley. Working room comprises end cover, adjusting shaft, fixed disc, movable disc, receiving hopper.

Material crushing is processed in the working room, the material is feed from the receiving hopper above end cover, and enter the space between the two discs, and be crushed by squeezing, the crushed material is discharged from the two discs, and drops to the collecting bucket.

The principle of the adjusting system: rotate the hand wheel, let the adjusting shaft move forward or backward, thus adjust the space between the two discs, accordingly the size of the crushed material is adjusted.

2, Eccentric shaft is installed on the main body supporting seat through bearing, at one end of the shaft a flat key is set in for fixing the pulley, the movable jaw is installed on the eccentric part of the shaft.

3, There is adjusting system available for adjusting the discharging particle size, and the discharge outlet size. It is controlled by operating the handle.

4, Lock-in spring is located under the main body, fixed to the hook on the body through the spring, another end is connected to the adjustable screw bolt. When the connection rod swing forward, the spring will balance the inertia of the connection rod to ensure the movable disc and fixed jaw disc closely engaged.
