As shown in fig. 1-2, the crushing and screening system provided in this embodiment includes a control module (not shown in the drawings), a primary crusher 10, a primary conveyor 20 having a feeding end connected to a discharging port of the primary crusher 10, and a primary screening machine 30 having a feeding port connected to a discharging end of the primary conveyor 20. The control module, the crusher 10, the primary conveyor 20, the primary screening machine 30, the feeder 40, and the conveyors, the crusher, and the screening machine which will be mentioned below are modules or devices which are directly available from the market, are not important in the present embodiment, and are not described in detail in the present embodiment. Preferably, in the present embodiment, the feeder 40 is a vibratory feeder, and the primary conveyor 20 and each of the conveyors to be mentioned below are belt conveyors, although the belt lengths of the belt conveyors may be different.
The primary crusher 10 has a crushing motor (not shown in the figure) with a commercially available current sensing device (not shown in the figure) on its power supply line, which is in communication with the control module. The primary screening machine 30 has a first screen (not shown in the figure), and a first material level sensor (not shown in the figure) is arranged above the first screen, and the first material level sensor is a sensor which can be directly purchased from the market, such as an infrared sensor, a photoelectric sensor, and the like. The first material level sensor, the primary screening machine 30 and the primary crusher 10 are respectively in communication connection with the control module. When the primary crusher 10 is used, when a material entering the primary crusher 10 is hard, the crushing resistance is relatively large, so that the power supply current of a crushing motor is increased and is further detected by a current detection device, and at the moment, the control module controls the feeding machine 40 to reduce the feeding speed after receiving the information of the current detection device, so that the crushing quality is ensured; after the first material level inductor detects that the material on the screen has accumulated to a certain degree (specific accumulation amount can be set according to actual needs), information is sent to the control module, and then the conveying speed of the one-level conveyor 20 is reduced through the control module, the feeding speed of the feeder 40 can be reduced if necessary, accumulation is effectively avoided, the screening quality is ensured, energy is saved, the environment is protected, meanwhile, the process does not need manual intervention, the degree of automation is relatively high, and the labor cost is relatively low.
Preferably, the first screen cloth has a plurality ofly, and each first screen cloth from the top down arranges in proper order and the mesh reduces gradually, and first screen cloth all arranges for the horizontal plane slope, and simultaneously, one-level screening machine 30 still has a plurality ofly and the first play hopper 31 of the lower extreme linking of each first screen cloth, is located and is provided with one-level play hopper below the first screen cloth of below. In this embodiment, three first screens are taken as an example (i.e., the primary screening machine is a three-layer screening machine). Simultaneously, the crushing and screening system that this embodiment provided still includes the one-level return conveyer 50 of being connected with the control module communication, links up with the first play hopper 31 that is located the first screen cloth of the top and the feed end of one-level return conveyer 50, and the discharge end of one-level return conveyer 50 links up with the feed inlet of one-level breaker 10 or batcher 40. In this way, the coarse particles which are not filtered by the uppermost first screen mesh can fall into the corresponding first discharge hopper 31 under the action of gravity and vibration, and return to the first-stage crusher 10 or the feeder 40 through the first-stage return conveyor 50 for crushing again, so that the crushing quality is ensured; meanwhile, the particles which are not filtered on the other first screens except the uppermost first screen and the particles falling into the first-stage discharge hopper are sequentially coarse to fine from top to bottom, so that the particles with different thicknesses can be obtained. In addition, according to actual demand, also can set up the conveyer that links up with each play hopper and carry predetermined position with corresponding granule material to improve degree of automation.
Preferably, the crushing and screening system provided by the present embodiment further includes a second-stage crusher 60, a second-stage front-end conveyor 70, a second-stage rear-end conveyor 80 and a second-stage screening machine 90, which are respectively in communication connection with the control module, wherein the feeding end of the second-stage front-end conveyor 70 is connected to any one of the first discharging hoppers 31 (preferably, connected to the second first discharging hopper 31 from top to bottom), the discharging end is connected to the feeding port of the second-stage crusher 60, the feeding end of the second-stage rear-end conveyor 80 is connected to the discharging port of the second-stage crusher 60, and the discharging end is connected to the feeding port of the second-stage screening machine 90. Like this, the material that the fineness is great relatively and not carried back to primary crusher 10 or batcher 40 and carry out the breakage again can be sent into secondary crusher 60 and carry out the breakage in, alleviates primary crusher 10's burden, helps improving crushing quality simultaneously, and the material through secondary crusher 60 breakage can be sent into secondary screening machine 90 and sieve in, helps improving screening quality. Similar to the primary screening machine 30, the secondary screening machine 90 has a second screen (not shown in the figure) obliquely arranged relative to the horizontal, a second level sensor (not shown in the figure) commercially available is arranged above the second screen, the second level sensor may be the same as or different from the first level sensor in structure, and the second level sensor is also in communication connection with the control module and functions as the first level sensor, which is not repeated here. In addition, in this embodiment, the number of the second screen is one less than that of the first screen, that is, the secondary screening machine is a double-layer screening machine, each second screen is sequentially arranged from top to bottom, and the meshes of the second screen are gradually reduced, and the specific mesh apertures may be set according to actual needs, and are usually smaller than the mesh aperture of the uppermost first screen; the secondary screening machine 90 further has two or more second discharge hoppers 91 connected one-to-one to the lower ends of the second screens, and a secondary discharge hopper (not shown) is provided below the lowermost second screen, and when a conveyor is provided below the primary discharge, the conveyor is preferably located directly below the secondary discharge hopper. In addition, the second first discharging hopper 31 from top to bottom and the second discharging hopper 92 at the top can be the same discharging hopper, so that the particles which are not filtered by the second screen at the top can be conveniently sent back to the secondary crusher 60 for crushing.
