Vertical shaft impact crusher is a new type of sand making machine launched by Dahua Heavy Industry, the main characteristics are high output, good effect, can process materials below 50mm into aggregates below 5mm, the finished materials are cubic shaped, full and uniform particles, welcomed by the market. So what is the working principle and characteristics of vertical shaft crusher?
1. The working principle of

There are two types of vertical shaft crushers: sand making and shaping.
Vertical shaft sand crusher, the material enters from the center of the impeller, is thrown out after being accelerated in the impeller, and hits the circumferential guard plate of the crushing chamber, and after many impacts and frictions, the material is broken into fine particles.
Vertical shaft shaping crusher, when the material enters, it is diverted by the material distribution plate, part of it enters the impeller and is thrown out after being accelerated, and part of it falls from the waterfall around the impeller, and the material is hit by the acceleration of the impeller.
Second, the production capacity of vertical shaft crusher
The production capacity of the vertical shaft crusher depends on the softness and hardness of the crushed materials and the purpose of crushing, sand making or shaping.
For soft materials, the feed particle size of the vertical shaft crusher is required to be below 35-50mm, and the feed particle size of hard materials should be limited to 30-45mm.
The shaping production capacity of the vertical shaft crusher is higher than that of sand making, which can process 80-650 tons of materials per hour during shaping, and 40-365 tons of materials per hour during sand making.
3. Advantages and disadvantages of vertical shaft crusher
1. Advantages of vertical shaft crusher
Large output: The vertical shaft crusher has a deep crushing chamber, which increases the output by 30% compared with the previous sand making machine.
The wearing parts are fully utilized: the circumferential guard plate in the crushing chamber is continuously subjected to the impact of the material, and the wear speed is very fast, and the circumferential guard plate of the impact crusher has increased the design that can be flipped up and down, and when one end is seriously worn, it can be turned over for use to prolong the service life of the perimeter guard.
Advanced lubrication method: The lubrication system of the impact crusher adopts an interchangeable modular design, so that the equipment can be freely converted between the mode of thin oil lubrication and grease lubrication, and the user can flexibly choose according to the production environment.
Dustproof and low noise: the vortex chamber of the equipment can realize the self-circulation of the air flow, and then equipped with a pulse dust collector to control the dust problem during crushing and sand making, and at the same time install a noise eliminator to reduce the noise when the equipment is working, and comply with the requirements of the national environmental protection policy.
2. Disadvantages of vertical shaft crusher
Just like the two sides of a coin, vertical shaft crusher has advantages, and naturally there are some disadvantages.
Unable to deal with high-humidity materials: when the moisture content of the material exceeds 8%, it is easy to adhere to the crushing chamber, bond into a clump when the equipment is discharged, block the discharge port, and affect the work efficiency.
High investment cost: The market price is directly proportional to the strong working capacity of the vertical shaft crusher, the price will be higher, and the wearing speed of the wearing parts such as the throwing head, plate hammer and perimeter guard plate is also relatively fast, and the replacement cost is relatively high.
At present, many sand and gravel yards, cement plants, and mineral processing plants will use vertical shaft crushers to undertake the refinement of materials. But before that, I would like to remind everyone to be optimistic about the advantages and disadvantages of this device, and evaluate which of the pros and cons of using it is greater!
