self-grinding machine describe

Self-grinding machine, also known as medialess grinding machine. The self-grinding machine has two driving modes: variable speed and different power and fixed speed, and some self-grinding machines are also equipped with micro-motion devices. In order to facilitate maintenance, it is equipped with a cylinder jacking device; for large mills, in order to eliminate the static resistance moment at startup, modern advanced technologies such as hydrostatic bearings are used to ensure the safe operation of the autogenous mill. The biggest advantage of the autogenous mill is that the raw ore from the stope or the coarsely crushed ore can be directly fed into the mill. Usually minerals are fed into the mill rod mill according to a certain particle size ratio. The autogenous mill can grind the material to 0.074mm at one time, and its content accounts for more than 20% to 50% of the total product. The crushing ratio can reach 4000-5000, which is more than ten times higher than that of ball and rod mills. The autogenous mill is a new type of grinding equipment with both crushing and grinding functions. It uses the material to be ground itself as the medium, and achieves pulverization through mutual impact and grinding, hence the name of the self-grinding machine.

self-grinding machine Features

1. The end cap and the cylinder are not connected vertically, and the end cap liner is tapered;

2. The ore discharge grid plate is added on the side of the ore discharge end. The material discharged from the grid plate passes through the conical drum screen, the material under the screen is discharged from the discharge port, and the material above the screen is returned to the self-grinding machine through the spiral self-return device for regrinding. , forming a self-closed-circuit grinding, which can further control the particle size of ore discharge and reduce the amount of ore returning;

3. The mine feeding side adopts a mobile feeding trolley;

4. The large gear is fixed on the hollow journal at the discharge end. The rest of the structure of the wet autogenous mill is roughly the same as that of the dry autogenous mill
