Description
Technical Field
The utility model relates to an ore crushing equipment field, concretely relates to crushing and screening system.
Background
At present, the crude ore in the existing phosphoric acid workshop is used as the raw material of a ball mill after secondary crushing, and the ore after primary crushing is completely conveyed into a second crusher through a belt for crushing. In the process, because the granularity of the ore is different, the ore enters the crusher completely, and the crushing difficulty of the crusher is increased. The crushing gap is adjusted to be small, and the ore is not supplied; the crushing clearance is enlarged, the feeding granularity of the ball mill is large, and the machine-hour yield of ore pulp is reduced. In rainy and snowy days, the crusher can be blocked due to the fact that the ore humidity is high and the ore feeding amount is slightly large. If the crusher is not timely found, the workshop can be stopped due to serious blockage of the crusher, and generally 1 hour is needed for cleaning. The belter also encounters safety risks during the cleaning process.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned not enough, and provide a crushing and screening system.
The utility model comprises a first ore crusher, a first conveyor, a crusher feed hopper, a second conveyor and a second ore crusher,
the feed hopper of the crusher comprises a hopper body, a group of sieve bars and a collecting hopper,
the top of the hopper body is provided with a feeding hole, the bottom surface of the hopper body is an inclined plane, the bottom of the hopper body is provided with a discharging hole, the bottom of the hopper body is provided with a screen bar mounting groove, a group of screen bar fixing rods are sequentially arranged in the screen bar mounting groove and are fixedly arranged on the screen bar fixing rods in the screen bar mounting groove, a screening gap is formed between every two adjacent screen bars, the inlet end of the collecting hopper is detachably arranged at the bottom of the screen bar mounting groove of the hopper body, the outlet end of the collecting hopper is connected with a discharging pipeline,
the discharge gate of first ore crusher is linked together with the feed inlet of first conveyer, and the exit end of first conveyer is located the feed inlet top of breaker feeder hopper, and the discharge end of unloading pipeline is linked together with the feed end of second conveyer, and the discharge gate of hopper body is linked together with the feed inlet of second ore crusher.
The screen bars are manganese steel screen bars.
The width of the screening gap between every two adjacent screen bars is 5-15 mm.
The first conveyor and the second conveyor are both belt conveyors.
The utility model has the advantages that: grading is implemented to current ore through the breaker feeder hopper, and qualified raw materials are direct to the conveyer belt on, and unqualified raw materials are on the conveyer belt again behind the breaker. The improved crusher has the advantages that the service life of the jaw plate of the crusher is prolonged, the probability of blockage of the crusher is reduced, the labor intensity of a workshop is reduced, and the production safety risk is reduced.

Detailed Description
As shown in the attached drawings, the utility model comprises a first ore crusher 1, a first conveyor 2, a crusher feed hopper 3, a second conveyor 4 and a second ore crusher 5,
the crusher feed hopper 3 comprises a hopper body 6, a group of screen bars 7 and a collecting hopper 8,
the top of the hopper body 6 is provided with a feeding hole, the bottom surface of the hopper body 6 is an inclined surface, the bottom of the hopper body 6 is provided with a discharging hole, the bottom surface of the hopper body 6 is provided with a screen bar installation groove, a group of screen bar fixing rods 9 are sequentially arranged in the screen bar installation groove, a group of screen bars 7 are sequentially arranged and fixedly installed on the screen bar fixing rods 9 in the screen bar installation groove, a screening gap is formed between every two adjacent screen bars 7, the inlet end of the aggregate hopper 8 is detachably installed at the bottom of the screen bar installation groove of the hopper body 6, the outlet end of the aggregate hopper 8 is connected with a discharging pipeline 10,
the discharge gate of first ore crusher 1 is linked together with the feed inlet of first conveyer 2, and the exit end of first conveyer 2 is located the feed inlet top of breaker feeder hopper 3, and the discharge end of unloading pipeline 10 is linked together with the feed end of second conveyer 4, and the discharge gate of hopper body 6 is linked together with the feed inlet of second ore crusher 5.
The screen bars 7 are manganese steel screen bars.
The width of the screening gap between every two adjacent screen bars 7 is 5-15 mm.
The first conveyor 2 and the second conveyor 4 are both belt conveyors.
The working mode and principle are as follows: the coarse ore is through 1 broken backs of first ore crusher, carry the breaker feeder hopper 3 in by first conveyer 2, the ore that enters into in the breaker feeder hopper 3 at first falls the bottom of breaker feeder hopper 3, roll to the exit end along the interior bottom of breaker feeder hopper 3, at the rolling in-process of ore, the fine ore falls through the screening clearance, is collected by collecting hopper 8, then send to second conveyer 4 through unloading pipeline 10 on, directly send to the fine ore storage place. The coarse ore is sent from the bottom discharge port of the crusher feed hopper 3 to the second ore crusher 5 for secondary crushing, and the crushed ore is also sent to a fine ore storage place by the conveyor.
