Optimizing Bucket Elevator Discharge Chutes

In 2022, a cement plant initiated a project to renovate its bucket elevator discharge chutes. They entrusted Nantong Darko Building Materials Machinery Co., Ltd. with the entire process, from production to equipment installation and operation. Darko quickly dispatched technicians to the site for an on-the-spot evaluation. They identified several key issues with the discharge chutes.



Main Issues


1.Insufficient Wear Resistance: The discharge chutes used wear-resistant manganese steel plates, which had poor durability. This led to multiple wear-through points and material leakage. The worn manganese steel plates became uneven, causing material to stick.

 

2.Unreasonable Structural Design: The angle in the middle of the discharge chutes was too steep, failing to effectively cushion the material. As a result, the lower part of the chute experienced severe wear.

 

3.Uneven Design of the Sloped Chute: The design of the sloped section was uneven. Material concentrated on one side, while the other side showed little wear. This uneven force distribution caused severe wear on the side in contact with the material and led to material accumulation.


Solutions


To address these issues, Darko's technicians proposed practical solutions:

1.Optimize Overall Structure: They adjusted the angle in the middle of the discharge chutes to reduce the impact force of the material. This modification effectively slows down and cushions the material.


2.Redesign the Sloped Chute: They changed the lower sloped section from an irregular rhomboid shape to a parallelogram. This design distributes the impact force more evenly across the bottom and sides, extending the equipment's lifespan.

 

3.Replace Wear Materials: They substituted wear-resistant ceramic liners for the manganese steel plates. The ceramic liners offer superior wear and corrosion resistance, and their smooth surface reduces material buildup.


Simulation Testing and Expected Results


Darko's technicians conducted simulation tests using the new solutions. They expect to increase the lifespan of the bucket elevator discharge chutes by 3 to 5 times, improve work efficiency by 3% to 12%, and reduce the likelihood of material blockage by 20% to 30%.

These design optimizations will significantly enhance the performance of the discharge chutes. They will ensure the cement plant's production efficiency and the long-term stability of the equipment.

Advantages of Baghouse Dust Collectors in Dust Management of Stone Processing Plants

图片
  In the dust management of stone processing plants, baghouse dust collectors stand out due to their significant advantages, particularly in efficient filtration, energy savings, ease of maintenance, and adaptability to various working conditions. What is a Baghouse Dust Collector? A  baghouse dust collector  is a device that filters gases through special filter bags. It effectively captures fine dust particles in the air. Its core technology involves precisely woven bag materials that ensure high dust removal efficiency. High Filtration Efficiency Baghouse dust collectors  use advanced filtration mechanisms to ensure the cleanliness of exhaust gases. They not only comply with national and local environmental standards but also significantly reduce the risk of environmental pollution caused by dust emissions. In processes like crushing, screening, and transporting in stone processing plants, baghouse dust collectors can control dust emissions to very low levels, achi...

Quality Control in Cement Grinding Process

图片
  S Cement Plant is a modern dry-process   cement plant . It uses advanced grinding equipment and technology. The plant employs a CKP vertical mill and a ball mill in a closed circuit system. The CKP mill is CKP-170, and the   ball mill   has dual chambers with specifications of φ3.9m×12m. It features a cyclone separator. The system's capacity is 115t/h×2.   Clinker and gypsum go through a crusher and break down to particles of ≤40mm, which make up over 95%. They are fed into the CKP mill. The material from the CKP mill contains over 95% of particles ≤10mm. About 10% of this material returns to the CKP mill, while roughly 90% moves to the ball mill along with the separator's return. The ball mill's output combines with fly ash and enters the separator. The separator achieves an efficiency of about 60%, with a circulation load rate of approximately 260%. Most of the cement produced is P.O 42.5R, with a small amount of P.II 42.5R. The average power consumption for...
