The structure of the central chain bucket elevator hoist has: 1, single-chain single-bucket structure; 2, double-chain double-bucket structure;
This structural performance is particularly suitable for improving the delivery of high temperature, large particles, and abrasive properties. For example, in clinker conveying system, rolling machine circulation system and other systems with poor transportation conditions, high efficiency and trouble-free operation are guaranteed in the future, which fully satisfies the reliability and high life of modern large-scale cement plants for hoist equipment. The highest demand for large throughput.

1 . Chain
Complete, specific, and scientific manufacturing processes ensure high precision in every part of the chain
The special hole technology ensures the uniformity of the pitch and aperture of the chain link; the forged chain plate of the precision friction press ensures the high wear life and high fatigue resistance of the chain chain plate, and the special medium frequency heating equipment ensures the chain. The highest hardness of the chain pin surface and the deepest hardness layer, the longest wear life, to avoid sudden breakage of the chain pin shaft impact. The suitable interference fit between the sleeve and the link plate can create beneficial stresses on the mating surface of the link, greatly increasing the fatigue life of the chain.
Detachable chain with easy loading and unloading
EXCT central chain bucket elevator has a hoist chain that does not touch the pin and the chain plate. It can be installed and formed without the need of any auxiliary tools at the installation site, which solves the problem of site installation of large chains with difficult installation on site. .
EXCT uses high-quality detachable forging central chain structure, the middle pin can rotate freely 360 degrees, the wear surface utilization rate is 100%, the lifting height is over 60 meters, the lifting capacity can reach 2000t/h, and the bucket speed can reach 1.8m/s with three-point friction drive.
The chain and sprocket drive is accomplished by three points of contact between the chain inner chain and the rim.
The inner/outer chain plate of the central chain is forged from high-quality 410Cr alloy structural steel. The hole machining is processed by advanced CNC machine tools, which ensures the accuracy of the hole and the coaxiality of the chain pitch. The inner chain plate adopts the press. Fitted with a moderate interference fit to ensure the stability of the chain.
2. pin shaft, sleeve
The pin and sleeve are made of high-quality 42CrMo alloy structural steel, in which the heat treatment process is performed on the surface medium frequency quenching after quenching the workpiece to ensure the internal impact resistance, fatigue resistance and surface wear resistance of the pin (surface hardening depth up to 3mm) Above, the hardness reaches HRC55-60) The service life of the pin shaft can reach more than 30,000 hours.
3. sprocket
The head/tail sprocket is made of high quality 42CrMo and is forged on an advanced CNC ring rolling machine. The surface of the wheel ring is also made of medium frequency quenching process (hardening depth up to 5m, hardness up to HRC58-60) and service life up to 20,000 hours. At the same time, EXCT also adopted a detachable assembly method. The head wheel ring is divided into three pieces (one piece per 120 degrees), and the tail wheel ring is divided into two pieces (one piece per 180 degrees). It is convenient to replace and disassemble without removing the chain, the hopper and the wheel hub, and greatly shorten the chain maintenance. time.
The sprocket-type toothless driving structure is because the energy transfer between the sprocket and the chain relies on the three-point friction between the chain and the chain to ensure uniform wear around the rim, and the sprocket diameter and the pitch of the chain are adopted. Non-odd fit, the contact position of the chain and the sprocket for one week is not at the same point, which greatly improves the service life of the sprocket.
4. Bucket
The central chain bucket elevator hanve bucket and chain assembly is uniquely designed. The function of the M-type back plate between the hopper and the chain is to fix the chain outer chain plate to prevent the hopper from falling off when the hopper is accidentally damaged, and the second effect is to effectively reduce the vibration between the hopper and the chain. Prevent the back of the hopper from tearing due to fatigue. In addition, a wear-resistant belt formed by wear-resistant welding is used at the edge of the hopper, which greatly improves the service life of the hopper.
5. tail
The  central chain bucket elevator is made of the latest gravity tensioning structure in Germany. The structure is composed of a tail weight and a high hardness without the need for maintenance of the hardened bearing steel. The central chain bucket elevator has low use cost, convenient maintenance and replacement, and high reliability of equipment use. Therefore, the operation is reliable, stable, low noise, and good sealing performance.Central chain bucket elevator produced by Henan Excellent Machinery Co., Ltd. is advanced technology, excellent craft, reliable performance.
