Scope of application: It is mainly used in the fine crushing and secondary crushing of various ores, especially for abrasives, quartz sand, limestone, river pebbles, granite, concrete aggregates, refractories, bauxite clinker, metallurgical slag, emery and other hard and brittle materials with a water content of no more than 20%.
Operational advantages
1. The cover opening device is convenient for maintenance personnel to enter the interior when the machine is maintained, so as to ensure that the parking time is short and easy to install.
2. The vertical shaft impact crusher can control the product particle size by optimizing a variety of variables, such as: changing the rotor speed; with different annular crushing chambers; adjust the waterfall flow; with rotors of different diameters.
3. Due to its low maintenance requirements and ease of operation, XHL High Efficiency Impact Crusher can be easily and quickly matched to existing or planned crushing equipment.
4. The installation is simple and fast, the crusher only needs a very little support structure, and it is an ideal mobile equipment.
5. Able to control the product particle size, so that the fine material output is as large or small as possible.
6. Able to produce high-grade cube products.
7. Excellent monomer degranulation characteristics to improve mineral recovery rate.
8. Selective crushing action.
9. A variety of models can be used for any fine crushing and fourth stage crushing.
Working Principle
The central feed of the sand making machine is accompanied by the annular waterfall and the feed material falls into the feed hopper, and then falls through the annular hole, and is divided into two strands by the bulk material tray. One strand enters the high-speed rotating impeller through the distribution tray, and the other strand falls from the periphery of the distribution tray, and the material that enters the impeller is thrown out at high speed after being rapidly accelerated in the impeller, and is first crushed with another part of the material in free fall around the bulk material tray, and then impacts the vortex material lining (or on the impact block) in the surrounding vortex cavity together, which is first rebounded to the top of the crushing cavity, and then deflects to move downward, and the material emitted from the impeller flow channel collides to form a continuous material curtain, and finally discharges through the lower discharge port.
Project examples
The high-efficiency impact crusher uses a waterfall feeding system to introduce a second material flow into the crushing chamber with a certain amount of control. The material density in the crushing chamber is increased, which promotes the energy exchange between the particles. The material entering the crushing chamber collides violently with the suspended material and the material liner, and collides with the material emitted from the runner again, and the material that has lost energy is discharged from the crushing chamber. When the crusher is running, the waterfall feeding system can adjust the size of the waterfall through external hydraulics to control the particle size composition of the product. The waterfall control system can be flexibly adjusted hydraulically or manually, which allows the crusher to adapt to changes in the feed, facilitating control of particle quality and fine content.
