(54) MBCHAMBER PARTITION FOR PIPE MILLS

Fig. 1 is a schematic representation of a spherical pipe mill with an inclined inter-chamber partition; figure 2 - section aa in Fig .; on fig.Z - section bb in figure 2; on . FIG. 4 - node 1 in figure 2.

The partition 1 is installed in the housing 2 of the mill lined with armored tiles 3.

The partition 1 consists of fixed rods 4, side surfaces; which are equipped with protrusions 5, and movable rods. b. The protrusions of the rods 6 are inclined to the horizontal axis of the partition at an angle o (40-55. The protrusions 5 are located at a distance t equal to the stroke S of the movable rod, thus achieving cleaning of the entire lateral surface of the movable rod.

In the process of operation, the meters of the interchange 1 change their position, which ensures the reciprocating movement of the movable rods 6 relative to the fixed ones 4. At the same time, particles of the material, or fragments of grinding bodies, stuck between the rods into the partitions, move to the projections 6 rods and, falling on their inclined edge 7, Vytshvgiots from the slit in the direction of the camera B coarsely ground, or in the direction of the chamber B fine grinding of the mill.

The stroke of the movable rods is 100-200 mm. This value is caused by the thickness of the armor. Increasing the travel of moving rods over 120 mm increases the dynamic load on the mill housing, reducing the stroke of rods less than 100 mm reduces the efficiency of the gap cleaning process.

The large mass of pd-sliding rods (30-70 kg) provides significant ejection forces acting on the jamming particles of the material, or grinding media, and increases the efficiency of the process of cleaning the cracks

The value of the angle L of the tilt of the edges 7 of the protrusions b is 40-55 is optimal. SCH5I increasing the angle

160-70 ° The magnitude of the normal buoyancy component is reduced. In addition, resistance increases. The movement of the movable rod 5. As the angle of inclination of the edge decreases from the projections 6 to 30, the edge strength decreases, as a result of which the possibility of its crumbling increases.

The present invention provides significant efficiency.

the process of cleaning the gaps of the partition and increases its throughput.

The expected effectiveness of the implementation of the invention, the increase in throughput of the partition and the stability of the material passing through, is 0.15 p / ton of crushed material {at a cement plant's production capacity of 2 yl. Tons of cement per year, the annual economic effect is -.

0 em 300000 p).
