A vacuum pump is a device that removes gas molecules from a sealed volume to create a partial vacuum. It works by creating a low-pressure area inside a chamber, causing the gas molecules to move towards the pump and be removed from the chamber. Vacuum pumps are used in a variety of applications, including in the production of electronic components, in medical equipment, in refrigeration systems, and in scientific research. There are several types of vacuum pumps, including rotary vane pumps, diaphragm pumps, and scroll pumps, each with its own advantages and disadvantages.

The impact crusher operates by using a high-speed rotating rotor driven by a motor. As the material enters the area where the hammers are located, it is struck by the hammers and then thrown against the counter-attack device. After being hit, the material rebounds from the counter-attack liner back into the hammer's action zone. This process repeats multiple times, with the material passing through the first, second, and third counter-attack chambers until it reaches the desired particle size. Finally, the crushed material is discharged through the outlet.
The stone material falls directly into the high-speed rotating turntable. Under the influence of centrifugal force, the stones are thrown outward and collide with each other at high speed, resulting in dense crushing. After these collisions, a vortex motion is created between the turntable and the casing, leading to multiple impacts, friction, and further fragmentation. The material is then discharged directly from the bottom. This cycle continues, and a screening device controls the final particle size, ensuring it meets the required specifications.
The development of the impact crusher represents a significant advancement in crushing technology, integrating foreign expertise with local innovation. It features advanced manufacturing techniques and a unique structural design, producing cubic-shaped products without internal stress or cracks. This machine can crush a wide range of materials, including coarse, medium, and fine ores, with a feed size not exceeding 500mm and compressive strength up to 350MPa. It is widely used in industries such as mining, construction, cement, and chemical processing.
One major drawback of the impact crusher is the rapid wear of the hammers and the counter-attack plates, especially when processing hard ores. This wear requires frequent maintenance and replacement, which can increase operational costs. However, China has made significant progress in researching and developing wear-resistant materials, leading to improved durability and performance in modern impact crushers. These machines are now commonly used in most metal concentrators across the country.
In addition to impact crushers, other equipment such as grader flotation machines and magnetic separators are also essential in mineral processing. For more detailed information about our products and services, please visit our official website: http://.
