The steel ball pack completeness of above-mentioned semi-autogenous mill is 6%-15%.

The steel ball pack completeness of above-mentioned ball mill is 30%~38%.

Operation principle of the present utility model: after the granularity of the raw ore of exploiting out through being crushed to 0~350mm, send in the semi-autogenous mill, utilize the steel ball of ore self and interpolation to carry out ore grinding.The ore of discharging from semi-autogenous mill is after vibratory sieve or drum sieve classification, coarse fodder returns semi-autogenous mill on the sieve, or disintegrating machine, product after the fragmentation is given to semi-autogenous mill or ball mill, sieve fines down feeds the ball milling loop, the ball mill ore discharge is behind cyclone classification, and the cyclone sand setting returns ball mill, and the cyclone overflow is given to the flotation operation operation.

Beneficial effect:

1, the utility model is compared with conventional fragmentation-ball milling ore grinding device, and the adaptive capacity of handling various ores improves, and can adapt to the variation of feed character such as hardness, granularity, clay content, moisture etc. effectively, makes whole process system apparatus more stable, is easy to control.

2, Semi-Autogenous and screening does not have dust to produce point for wet operation, does not need to ventilate and gathers dust, and energy consumption reduces, and does not also influence surrounding environment, and is fit to handle clay content height, material that moisture is big, does not influence the running rate of device.

3, the utility model is compared with conventional comminution process system apparatus, reduced mass transport belt that two sections crushing operations, two step-sizing operations, many circulations come and go and in the dust collecting system of a configuration of respectively gathering dust, whole apparatus structure is greatly simplified, reduced construction area, saved investment, reduced intermediary operation and controlling unit, also saved operation cost, easy operating and management.

4, the steel ball pack completeness of semi-autogenous mill is 6%~15%, and the steel ball pack completeness of ball mill is 30%~38%, and suitable steel ball pack completeness has improved the comminution operating efficiency.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model.

1-oscillating feeder, 2-semi-autogenous mill, 3-first ribbon conveyer, 4-vibratory sieve, 5-sand pump pond, 6-second ribbon conveyer, 7-disintegrating machine, 8-the 3rd ribbon conveyer, 9-slag stock pump, 10-cyclone, 11-ball mill.
