A central chain machine, such as the ZYL Central Chain Bucket Elevator, is a device used for vertically or obliquely lifting various bulk materials. It mainly consists of operating components (including hopper and central chain), driving device, upper device, middle casing, and lower device. This equipment adopts inflow feeding and centrifugal throwing, and has the characteristics of high lifting capacity, low driving power, wide lifting range, high lifting height, long service life, good operational reliability, and convenient maintenance. Widely used in industries such as mining, metallurgy, coal, building materials, chemical industry, and grain, it can improve powder, granular, and block materials, including materials with high grindability and materials with temperature ≤ 250 ℃.

　　Central chain machines are widely used in industries such as mining, metallurgy, coal, building materials, chemical, and grain to lift various bulk materials, such as ores, coal, cement, grains, fertilizers, etc. According to the requirements of the conveying process, it can be conveyed by a single machine, or by multiple machines or combined with other conveying equipment to form a horizontal or inclined conveying system.

　　1. High capacity improvement: Adopting inflow feeding, centrifugal throwing, and densely arranged large capacity hopper conveying, with fast chain speed and large lifting capacity. The range of improvement is 100~1600m 3/h.

　　2. Low driving power: During material lifting, there is no material return or excavation phenomenon, so the ineffective power is low. The theoretical calculation of shaft power is about 45% of that of the chain hoist.

　　3. Wide range of improvement: There are few requirements for the type, characteristics, and block size of materials, which can not only improve powder, granular, and block materials, but also improve materials with high grinding ability and materials with temperature ≤ 250 ℃.

　　4. High lifting height: With high chain speed, smooth operation, and the use of precision forged wear-resistant chains, it can achieve a high lifting height (70m).

　　5. Long service life: The feeding of the elevator adopts an inflow type, and there is rarely any squeezing or collision between the moving parts and the material. The design of this machine ensures that the material will not spill during feeding, lifting, and unloading, which prevents material wear on the machine body. The conveying chain adopts a precision forged high-strength wear-resistant chain, and the sprocket surface is specially heat-treated. Extended the service life of chains and sprockets.

　　6. Good operational reliability: Reasonable design ensures the reliability of the entire machine operation. The fault free time exceeds 30000 hours.

　　7. Convenient maintenance: The maintenance window and observation window are both designed with quick buttons for easy operation; The upper and lower sprockets are split type, making maintenance and replacement simple and fast.
