Problems solved by technology
[0004] Chinese patents CN101637765 and CN105499154 are lump coal and gangue automatic separation technologies based on double gamma and X-ray identification. They all use belt conveyors to identify mineral materials. No more than 100mm), double gamma and X-ray identification methods are harmful to the human body, the production equipment needs to take shielding measures to prevent the radiation from harming the human body, and the producer needs to go through the environmental protection procedures and annual inspection procedures for the use of radioactive sources
The separation of coal and gangue adopts high-pressure air blowing technology, which consumes a lot of power. When blowing coal with small water outside the coal, it will produce relatively large dust pollution, which will affect the working environment of workers.
The actual production application shows that the lump coal and gangue automatic sorting system represented by the above two patents has low sorting accuracy, small particle size of the processed mineral material, special protective measures are required for the identification technology to be harmful to the human body, serious dust pollution, and the system Disadvantages such as high installed power, which overlap with the compound dry sorting machine in the sorting granularity, the adaptability is not strong enough, and the scope of application is not wide enough
[0005] Chinese patent CN 106733684A uses an online detection device to judge and screen the types of mineral materials and separate them through the material guide mechanism. However, the composite non-radiation online non-destructive testing technology used in it has the defects of high manufacturing cost and difficulty in interval transportation.
[0006] At present, coal mines cannot solve the separation of lump coal with a particle size of 80mm ~ 300mm, and can only use manual picking. This process mainly has high labor costs; high missed and wrong picking rates; The quality is uneven, the sorting efficiency is low; the emotional fluctuations of personnel directly affect the sorting efficiency and other defects

Embodiment Construction
[0027] Below in conjunction with embodiment the present invention is described in further detail:
[0028] Such as figure 1As shown, a mineral material dry separation system includes a vibrating feeder 1, a conveyor belt 2 arranged at the discharge end of the vibrating feeder 1, and an ore material arranged at the discharge end of the chute buffer bin 2. Separation device, the mineral material separation device arranged at the discharge end of the mineral material separation device and the PLC controller connected with the mineral material separation device and the mineral material separation device; The speed-regulating type can effectively adjust the feeding amount of the mineral material. Under the action of the exciting force, the mineral material is evenly sent to the discharge end of the vibrating feeder 1. The feeder 1 is fixedly connected, and the chute buffer bin 2 provides a buffer feeding function for the vibrating feeding process, and with the continuous vibration...

The invention relates to a dry separation system and method for mineral aggregate. The system comprises a vibration feeder, a sliding groove buffering bin, a mineral aggregate separating unit, a aggregate separation device and a PLC, wherein the sliding groove buffering bin is arranged at the discharging end of the vibration feeder, the mineral aggregate separating unit is arranged at the discharging end of the sliding groove buffering bin, the mineral aggregate separation device is arranged at the discharging end of the mineral aggregate separating unit, and the PLC is connected to the mineral aggregate separating unit and the mineral aggregate separation device; the mineral aggregate separating unit comprises a first conveyor belt, a second conveyor belt and a third conveyor belt, wherein the first conveyor belt, the second conveyor belt and the third conveyor belt are sequentially arranged at the discharging end of the sliding groove buffering bin from left to right; a first proximity sensor is arranged at the second conveyor belt; and a weighing device and a volume measuring device are connected to the PLC. The dry separation system and method are particularly suitable for dryseparation of lump coal and lump gangue with the particle size of 80-300mm, are suitable for separation of the large-block mineral aggregate and are also suitable for separation of other mineral aggregate with density difference. The dry separation system and method have the characteristics of being high in separation precision, simple in process route, small in investment and low in operation cost.
Description
technical field [0001] The invention relates to a mineral material dry separation system and method, belonging to the technical field of mineral material separation. Background technique [0002] At present, the separation of coal and other mineral materials mainly has two directions: water washing and dry method. Water washing is still the mainstream of coal separation due to its large processing capacity and high precision, but it has disadvantages such as complex process system, high investment, high operating cost, large floor area, and high water resource consumption. , simple process route, less investment, and low operating cost, so dry separation is used in water-deficient areas, easy to peat coal, steam coal, lignite, coking coal pre-discharging gangue, gangue easy to mud, chemical coal, etc. There is a wide market space in the field. [0003] The dry sorting machines used in industrial production at home and abroad are mainly based on the compound dry sorting mac...
