The latest ball mill technology to the dressing industry peaked

Ball mill is divided into: cement ball mill, overflow ball mill, rod mill three, these three models are our main ball mill, each with its own unique use, the specific details, see the following three ball mill Operation details and product information:

Cement ball mill

Because of its unique grid plate and fan-shaped indoor lifting bucket, to achieve a low level of forced drainage, the mine has been able to promptly discharged ore particles have been qualified particles will not stay in the ball mill too long, so the phenomenon of over-smash Light, grinding speed, high efficiency.

Due to the low slurry level in the mill and the low mineral content, coupled with the "isolation" effect of the grating board, on the one hand a higher filling rate of the medium can be used to increase the loading capacity of the ball, After being lifted to a certain height, the ball has a relatively large drop height due to the relatively low pulp surface. Therefore, the impact of the medium ball is strong, and the crushing effect on the mineral material is great and the grinding effect is good.

Due to the high discharging speed and short residence time of mineral materials, the ground ore can be discharged into the classifier from the mill quickly to be classified into the subsequent operation, so that the mill can replenish more raw ore and the dense particles can not Ball mill aggregation, thereby reducing the over-crushing, increased productivity. Compared with the same size overflow type, the productivity is higher than 10% ~ 25%. The mill is suitable for the first section of roughing or two-stage grinding, but also for crushing and softer ores.

Overflow type ball mill

The mill discharge is due to the hollow end of the hollow shaft diameter slightly larger than the feed end of the hollow shaft diameter, resulting in the ball mill slurry discharge side have a certain inclination. When the pulp surface height is higher than the lowest busbar inner diameter, the pulp overflow overflow mill. This is a non-compulsory high-level ore discharge, discharge speed is slow, so the mineral material in the machine for a long residence time, the effective medium is also low, so overflow type ball mill excessive wear and tear, handling capacity than the same size grid Low type. Generally suitable for fine grinding or grinding in the second paragraph of two sections of grinding.

Rod mill

The medium in the rod mill is a steel rod, so after the level falls, it comes into contact with the ore material surface line, and has selective crushing effect, that is, crushing in turn from a large block to a small block according to the particle size, Suitable for coarse grinding or grinding products required over crushing light re-election plant.

There are 3 direct ways to improve the production of ball mill:

1 ball mill before adding crusher;

2. Improve ball mill grinding system, improve grinding efficiency;

3. Add efficient separator.

Ball mill in the use of mineral processing:

Mineral processing equipment - the first mining ore by the jaw crusher for initial crushing, crushing to a reasonable degree of fineness through the hoist, to the miner evenly into the ball mill, by the ball mill ore crushing, grinding. After the ball mill developed ore fines into the next process: grading. Spiral classifier with the specific gravity of solid particles in the liquid often different speed principle, the ore mixture classification.

Ball mill used in aerated concrete equipment:

Fly ash (or sand, stone powder) by electromagnetic vibrating feeder, belt conveyor into the ball mill, ground fly ash (or sand, stone powder) with a fly ash pump were sent to the slurry tank storage.

Lime by the electromagnetic vibrating feeder, belt conveyor into the jaw crusher for crushing, broken lime by the bucket elevator into the lime silo, and then into the ball mill by screw conveyor, after grinding the material by Screw conveyor, bucket elevator into the powder ingredient warehouse.
