Description

Technical Field

[0001] The present invention relates to the technical field of mineral processing, in particular to a mobile type crushing and grinding ore processing system. Background Art

[0002] Currently, the mining and processing process for open-pit non-magnetic mines mostly involves first crushing and grinding the ore to the required particle size for complete dissociation, followed by gravity separation or flotation, to produce a concentrate. Traditionally, separate, fixed concentrators are typically located, with the crushed ore transported to the concentrator via conveyor belts. For non-magnetic ores, many have a P80 (the particle size corresponding to an 80% cumulative yield in the distribution curve) particle size of 70 to 150 microns. Mineral dissociation can be achieved through a single ball mill. The resulting ore is fine, easily forming a pseudo-homogeneous flow. Furthermore, the hardness of most non-magnetic ores is relatively low, making the milled slurry particularly suitable for long-distance pipeline transportation, which is significantly less expensive than belt conveyor transportation. Therefore, if both ore crushing and grinding operations could be located at the stope, and the ground product could be transported via long-distance pipelines to the concentrator for sorting, the cost of ore transportation would be significantly reduced.

[0003] Chinese patent application publication number CN 106563553 A discloses a "crushing system and crushing process for an underground iron ore concentrator." The crushing system consists of a coarse crushing unit, a secondary crushing unit, a screening unit, a fine crushing unit, and a maintenance system. These units are arranged in a vertically descending staircase along the mining plant's transport tunnels, following the order of operation. The crushing process involves reducing the mined 600mm-1000mm ore through a coarse, secondary, and fine crusher to a particle size of 20mm-30mm. The undersize product is then fed to a vibrating screen and pumped to the roughing process of the grinding and concentrating system. The system has low energy consumption, requires no surface land, is environmentally friendly, and provides qualified raw materials for the subsequent grinding and concentrating system.

[0004] However, the above system is only suitable for underground mines and is a fixed arrangement. However, the mining areas of open-pit mines generally change year after year, and fixed crushing and grinding systems have low equipment utilization rates. If the coarse, secondary, and fine crushing and grinding systems and transportation vehicles could be integrated, and the integrated equipment could be quickly relocated as the mining area changes, the entire crushing, grinding, and ore dressing processing system would be fully mobile. This would enable the reuse of ore dressing equipment, significantly reducing the distance mined ore must be transported, and significantly reducing equipment purchase expenses and production costs. Summary of the Invention

[0005] The present invention provides a mobile crushing and grinding ore processing system, which integrates the crushing and grinding operations of non-magnetic ores into a movable system, enabling direct loading of concentrates onto trucks.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) The system integrates coarse crushing, medium crushing, fine crushing and grinding equipment with the train body. After three stages of crushing and grinding, the final particle size of the ore can be controlled at P80 = 70 to 150 microns, achieving mineral dissociation and creating conditions for obtaining good separation indicators in subsequent separation operations. The ground slurry after dissociation is transported to a fixed separation plant through a long-distance transmission pipeline, which has low transportation costs and good adaptability to terrain.

[0019] 2) The coarse crushing, medium crushing, fine crushing and grinding process equipment are integrated and installed on a train, eliminating the need for traditional fixed factory buildings and corresponding operation workshops, thus reducing infrastructure investment.

[0020] 3) After adopting the integrated mobile system, the secondary and fine crushing and grinding after coarse crushing are also set up in the stope. Compared with the traditional method of setting the coarse crushing in the stope and transporting the coarse crushed products to the concentrator through belt conveyors for secondary and fine crushing and grinding, there is no need to transport the crushed ore over long distances, which reduces infrastructure investment and production costs and improves economic benefits.

[0021] 4) The equipment required for the coarse crushing, medium crushing, fine crushing and grinding process (including belt conveyors, power units, etc.) are all integrated into one train, realizing the full mobility of ore processing equipment. The entire set of processing equipment can be quickly moved and relocated as the mining area changes, greatly reducing the transportation cost of the raw ore and reducing production costs.

[0022] 5) After the system of the present invention transports each module to a new destination by train, the locomotive can leave, thereby improving the utilization rate of the locomotive.

[0023] 6) The grinding media is added by a truck crane, and the conveying and mixing tank can also be lifted onto the train body for transportation, thus realizing the mobility of all auxiliary facilities and then the mobility and reuse of all ore processing equipment.

[0024] 7) The coarse crushing module, medium crushing module, fine crushing module and grinding module are integrated into one vehicle body, that is, the unit integration method is adopted. After the operation of a certain mine is completed, each operating unit can be transported to other mines by train alone, and can be used in combination as needed, which improves the utilization rate of the equipment and avoids asset sinking.

[0025] 8) Coarsely crushed products, medium crushed products, and finely crushed products are all transported to the next process by bucket elevators, which realizes the vertical lifting of ore, greatly reduces the distance between upstream and downstream working sections, and creates conditions for integrating all ore processing equipment on a train.

[0026] 9) The belt conveyor is suspended on one side of the car body during transportation and is placed horizontally on the corresponding car body during operation. That is, the position of the belt conveyor is different in the transportation state and the working state, which creates conditions for integrating all ore processing equipment into one train.

[0027] 10) The coarse crushing module is equipped with a truck trestle because the particle size of the ore fed into it is generally around 1000mm and cannot be transported by belt conveyor. The medium and fine crushing modules are fed with ore by bucket elevator because the particle size of the ore fed into them is relatively small. The overall structure of the system is compact and the layout is simple and reasonable, realizing a compact layout of the three operating modules.

[0028] 11) The system described in the present invention sets the crushing devices in the coarse crushing module, the medium crushing module and the fine crushing module on the corresponding vehicle body through corresponding portal frames. The portal frames are pushed by corresponding hydraulic push rods to realize the conversion of the crushing devices from the transportation state (horizontal state) to the working state (vertical state), thereby realizing the transfer of the system between different mining areas and improving the working efficiency.

[0029] 12) When the coarse crushing module, medium crushing module and fine crushing module are in working state, they are supported on the foundation by corresponding ground anchors, that is, the vehicle body is not subjected to stress in the working state, which effectively protects the vehicle body.

[0030] 13) In the system of the present invention, when a failure occurs in the coarse, medium or fine crushing module, the crushing devices in the coarse, medium and fine crushing modules can be folded up using hydraulic push rods. The various parts of the coarse, medium and fine crushing modules are detachably connected to the platforms on each layer, and the platforms on each layer are detachably connected to the corresponding portal frames, thereby enabling the rapid disassembly, lifting and maintenance of the coarse, medium and fine crushing modules.

[0031] 14) In the system described in the present invention, the coarse crushing module, the medium crushing module and the fine crushing module are all equipped with independent control boxes, and the control ends of the hydraulic push rods of each operating module are respectively connected to the corresponding control boxes, thereby achieving a high degree of automation.
