The compound crusher is also called a "vertical compound crusher" because the body of the crushing equipment is upright. The so-called "compound" is because it combines two different crushing forms of impact crusher and hammer crusher into one. One operation cycle can achieve coarse, medium, and fine crushing. It has outstanding advantages such as one-time molding, large crushing ratio, energy saving, good sealing, and less dust. It fully simplifies the crushing process, improves efficiency, and reduces investment costs. The vertical crusher is an optimized design, mature technology, and widely used fine crushing equipment.
High crushing efficiency and low crushing cost
It has the advantages of impact crusher and hammer crusher. One device plays the role of two devices, which significantly simplifies the process and reduces investment costs.
One time can achieve coarse crushing, medium crushing and fine crushing.
When used in ore dressing, limestone and cement plants, it can significantly reduce the feed particle size of the subsequent ball mill, thereby increasing the output of the entire production line and reducing the energy consumption of the entire set of equipment.
Good sealing and no dust pollution
The crushing device has good sealing and no dust pollution.
Can be used for crushing materials with high water content
The discharge particle size can be easily adjusted and has strong adaptability. According to the data of the Kunming Crusher Technical Expert Group, materials with a water content of 8%-15% can enter the compound crusher for normal crushing.
The material falls vertically from the upper part of the machine into the high-speed rotating impeller. Under the action of high-speed centrifugal force, it collides and crushes with the other part of the material that is diverted around the impeller in an umbrella-shaped form. After colliding with each other, the materials will form a vortex between the impeller and the casing, and then rub and crush each other multiple times, and then be discharged directly from the bottom, forming a closed-loop multiple circulation, and the screening equipment controls the required finished product particle size.
The compound crusher consists of a transmission device, a body, a feeder and a support. The main body parts can be divided into a cover, a casing, a hammer head, a hammer disc, a liner, a center shaft, etc. The hammer head is fixed on the hammer disc in a radial layout, and the hammer disc is fixed on the center shaft in a stacked layer at a fixed interval. For the specific structural layout, please refer to the following vertical compound crusher internal structure profile:
The processing capacity of the vertical compound crusher equipment is affected by many factors, such as: the physical properties, shape, particle size composition, water content, workbench conditions, etc. of the crushed raw materials. The processing capacity listed in the above table is based on the crushing of dry and medium-hard rock as an example, and the bulk density is based on 1.6t/m3.
