The main factors affecting the jaw crusher work are the angle of the corner and the number of revolutions.
The angle of the jaw crusher is the angle between the momentum and the quota. According to the calculation, the maximum angle of engagement can reach 32, but in actual use, it is less than 25, generally about 18-20. If the angle of the teeth is too large, the ore in the crushing chamber will be extruded upwards, causing injury or damage to other equipment, and the productivity will decrease as the angle of the teeth increases (the crushing ratio increases). Adjust the size of the discharge port, which is the size of the angle. In actual production, the size of the discharge port is adjusted according to the requirements of the size of the ore discharge. Therefore, in order to ensure the product size requirements, it is reasonable to enlarge the discharge port as much as possible. The size of the discharge port can be adjusted by adjusting the block. Pay attention to the relationship between the crush ratio and the productivity when adjusting the size of the discharge port.
Within a certain range, increasing the number of revolutions of the eccentric shaft of the jaw crusher can increase the productivity of the crusher, but it also increases the power consumption of crushing the unit weight of ore. If the rotation speed is too large, the crushed chamber will not be discharged due to the broken ore, and the plugging phenomenon will occur, which will reduce the production capacity and increase the power consumption. Therefore, the jaw crusher should have an optimum number of revolutions.
The eccentric shaft, connecting rod, movable jaw, shaft and lining of the jaw crusher make the main wear parts require frequent attention to lubrication and replacement.
In the construction project, the large water mouth mold plays a crucial role. As a kind of support structure, the large water mouth mold has significant significance in ensuring the safety and stability of the project and improving the construction efficiency. This paper will introduce the related problems of large water mouth mold frame in detail to help readers better understand its application in construction engineering.
Large water mouth mold erection originated in the early 20th century, with the rapid development of the construction industry, its application gradually popularized. The large water frame is mainly used in the construction of large structures such as Bridges, high-rise buildings, factories, etc., to provide reliable support for reinforced concrete structures. The mold frame is composed of steel members and support system, which has high bearing capacity and stability.
In the construction project, the application scenarios of large water mouth mold are wide. For example, in bridge construction, the large water mouth mold can provide reliable support for the pier, beam plate and other parts of the bridge; In the construction of high-rise buildings, the large water frame can be used for cast-in-place floor slab and prefabrication of wall and column. In the construction of the plant, the large water mouth mold can be used to support the large-span beam, column and other parts.
The advantages of large water mouth die frame mainly include: improve construction efficiency, reduce labor intensity, save materials, shorten the construction period and so on. At the same time, there are also some shortcomings, such as high one-time investment costs, the need for professional design and installation teams. In view of these problems, the construction unit should fully consider the needs of the project and its own conditions, weigh the advantages and disadvantages, and choose the appropriate large water mouth mold scheme.
