Abstract
Description
Technical Field
[0001] This invention relates to mineral processing equipment technology, and in particular to a density-selective impact crushing equipment. Background Technology
[0002] Traditional ore crushing processes have the following technical drawbacks when processing polymers of different densities:
[0003] (1) Single crushing intensity leads to over-crushing of low-density soft materials and insufficient crushing of high-density hard materials;
[0004] (2) Existing sorting equipment cannot achieve dynamic matching between crushing strength and material characteristics. Summary of the Invention
[0005] The purpose of this invention is to provide a density-selective impact crushing equipment that, for materials containing different densities and corresponding different liberation intensities, selectively applies different liberation forces to ore particles of different densities, achieving precise crushing and liberation over a wide range in batches, thereby solving the problem of insufficient crushing of particles of different densities in the existing crushing technology.
[0006] To achieve the above objectives, the present invention provides the following solution:
[0007] This invention provides a density-selective impact crushing equipment, comprising a housing, a feeding device, a motor A, a blower, a crushing device, a distribution chute, a motor B, and a crushing hammer. Motor A is connected to the blower; the blower cooperates with the housing to generate an airflow field within the housing; the crushing device is installed below the distribution chute inside the housing. The crushing device includes motor B and a crushing hammer, with motor B driving the crushing hammer to rotate and crush the mineral.
[0008] Preferably, three crushing devices are provided, and the rotation speed of each crushing device can be set independently.
[0009] The present invention achieves the following beneficial technical effects compared to the prior art:
[0010] It can selectively apply different liberation forces to ore particles of different densities. The liberation force can be adjusted by the speed of motor B to achieve batch and wide-range precise crushing and liberation. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0016] The purpose of this invention is to provide a density-selective impact crushing equipment to solve the problems existing in the prior art.
[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] This embodiment provides a density-selective impact crushing device, such as... Figure 1 , Figure 2 As shown, it includes a housing 1, a feeding device 2, a motor A3, a blower 4, a crushing device 5, a material distribution chute 6, a motor B7, and a crushing hammer 8.
[0019] The present invention provides an installation method for a density-selective impact crusher:
[0020] The feeding device 2 is installed at the feed inlet of the box 1. The motor A3 is connected to the blower 4 and drives the blower 4 to work. The air outlet of the blower 4 is fixedly connected to the box 1. The material distribution chute 6 is fixedly connected to the box 1. The crushing device 5 is installed below the material distribution chute 6. Each crushing device 5 is equipped with a motor B7, so that the crushing device 5 can select different speeds and powers according to the material density.
[0021] The working principle of the density-selective impact crushing equipment provided by this invention is as follows:
[0022] Motor A3 is connected to and drives blower 4. The air blown out by the blower forms a horizontally uniform airflow field inside the housing 1 under the guidance of the airflow. Feeding device 2 feeds material into housing 1. The horizontal uniform airflow field has a horizontal conveying force on the falling material. Particles of different densities or sizes will have different lateral flight distances. The wind force blows the freely falling particles into different distribution chutes 6 according to their density and size differences. The material is fed into crushing device 5 through distribution chutes 6 for crushing. Multi-density separation is achieved at different distances using distribution chutes 6. Fragile low-density materials and small-sized materials are carried by the airflow field into the upper discharge chute and enter the light crushing device 5 for crushing to avoid over-crushing. Non-fragile high-density materials and large pieces of material are carried by the airflow field into the lower discharge chute and enter the high-strength crushing device 5 for crushing to achieve full separation. Intermediate materials are carried by the airflow field into the middle discharge chute for medium-strength crushing.
[0023] In general, when materials of different densities enter different material chutes 6, selective crushing is carried out by rotary crushing devices 5 with different rotation speeds. This allows low-density materials to rotate at low speeds to avoid over-crushing, while high-density materials enter the high-speed selective crushing device 5 to fully dissociate them.
[0024] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
