Abstract
The utility model relates to a hard stone bypass crushing system for an autogenous mill. The hard stone bypass crushing system comprises a feeding belt type conveyor for the autogenous mill, and the autogenous mill. The hard stone bypass crushing system is characterized in that a double-layer vibration sieve is arranged below an ore discharging funnel of the mill; a hard stone chute and the hard stone bypass crushing system are arranged on the lateral face of an upper layer sieve of the double-layer vibration sieve; the hard stone bypass crushing system comprises a plus sieve hard stone discharging belt type conveyor, a hard stone transfer belt type conveyor, a hard stone bypass belt type conveyor, a feeding belt type conveyor for a hard stone crushing and feeding chamber, a feeding belt type conveyor for a hard stone crusher, the hard stone crusher and a crushing product belt type conveyor, which are sequentially connected with one another. The hard stone bypass crushing system provided by the utility model has the advantages of simple system, convenience in maintenance, high operation rate, no spare crushing machine and low investment cost. The hard stone bypass crushing system can be used for feeding hard stones to the hard stone crushing system, and directly returning the hard stones to the autogenous mill for automatically milling when the crushing machine is maintained, so that the recovery rate of ores can be improved, and the treatment capacity of the autogenous mill can be ensured.
Description
Technical field
The utility model belongs to hard rock crushing technology field, ore dressing plant, particularly a kind of autogenous tumbling mill hard rock bypass crushing system.
Background technology
Because autogenous tumbling mill adopts the mutual mode ore grinding that impacts and grind of ore, so the ratio of reduction of autogenous tumbling mill is maximum in all crushing and grinding equipments.Use autogenous tumbling mill the ore of coarse crushing directly can be fed to autogenous tumbling mill, the product of autogenous tumbling mill closed cycle can directly enter grinding machine, so use autogenous tumbling mill with regard to broken and operation in small, broken bits in no longer needing, equipment and construction investment have been saved, and do not need to add milling medium with autogenous tumbling mill, reduced the operating cost of this operation.Broken and operation in small, broken bits during so autogenous tumbling mill is more and more widely used in ore dressing and substitutes.Autogenous tumbling mill feeding granularity is large, because autogenous tumbling mill relies on the impact between ore and grinds ore grinding, the high ore of part hardness just can not be grated and directly as hard rock, from autogenous tumbling mill mine-discharging terminal, discharge in autogenous tumbling mill, in order to guarantee the rate of recovery of ore dressing plant mineral, this part hard rock feeds autogenous tumbling mill with regard to necessary through fragmentation again.Because the operating rate of hard rock disintegrating apparatus is low compared with autogenous tumbling mill, generally for hard rock is broken, just need to adopt the method for a-worker-a-backup, but this method crushing plant factory building is large, construction investment is high, and equipment investment is also high.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of system, easy to maintenance, operating rate is high, disintegrating machine need not be standby, invest low, hard rock can be delivered to hard rock crushing system, can realize again in disintegrating machine maintenance, hard rock is directly turned back to autogenous tumbling mill in autogenous grinding, can improve the rate of recovery of ore and guarantee the autogenous tumbling mill hard rock bypass crushing system of the disposal ability of autogenous tumbling mill.
The purpose of this utility model realizes by following technical proposals:
Autogenous tumbling mill hard rock bypass crushing system of the present utility model, comprise autogenous tumbling mill feed ribbon conveyer, autogenous tumbling mill, it is characterized in that being provided with double-deck screen shale shaker below grinding machine ore discharge funnel, side at the upper sieve of double-deck screen shale shaker is provided with hard rock chute and hard rock bypass crushing system, described hard rock bypass crushing system comprises hard rock discharge ribbon conveyer on the sieve connecting successively, hard rock transhipment ribbon conveyer, hard rock bypass ribbon conveyer, the broken feed hopper feed of hard rock ribbon conveyer, hard rock disintegrating machine feed ribbon conveyer, hard rock disintegrating machine and crushed product ribbon conveyer, described hard rock discharge ribbon conveyer is vertically mounted on the below of hard rock chute, the material feeding end of hard rock transhipment ribbon conveyer is installed on lower floor's platform of hard rock discharge ribbon conveyer, delivery end at hard rock transhipment ribbon conveyer is provided with discharge chute, described discharge chute is dichotomous two discharge chutes, described dichotomous two discharge chutes are put respectively the top of the broken feed hopper feed ribbon conveyer material feeding point of hard rock and hard rock bypass ribbon conveyer material feeding point, being horizontally disposed with of the broken feed hopper feed ribbon conveyer of described hard rock and hard rock transhipment ribbon conveyer, the discharge funnel of hard rock bypass ribbon conveyer and the discharge funnel of crushed product ribbon conveyer are all installed on the top of autogenous tumbling mill feed belt conveyer belt, become closed cycle with autogenous tumbling mill feed ribbon conveyer.
The utility model has the advantages that:
1) hard rock of system autogenous tumbling mill of the present utility model is through the fragmentation of hard rock disintegrating machine, and the particulate product after fragmentation is giving back to autogenous tumbling mill continuation ore grinding, has improved the rate of recovery of selected mineral, has guaranteed the disposal ability of autogenous tumbling mill;
2) system of the present utility model can temporarily directly turn back to autogenous tumbling mill by hard rock by hard rock bypass ribbon conveyer in disintegrating machine maintenance, adopting in this way hard rock disintegrating machine does not need standbyly, has reduced the construction investment of hard rock crushing plant when reducing equipment investment yet.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
