Bucket Elevator for Limestone

What is Bucket Elevator for Limestone?

Bucket Elevator for Limestone is a vertical conveying equipment designed for abrasive materials such as limestone. It adopts plate chain traction and wear-resistant hopper design. It is particularly suitable for conveying abrasive medium and large limestone, limestone clinker and powdered limestone materials. The working temperature can reach 250℃ and the hourly conveying capacity can reach 800m³/h.

Compared with traditional conveying equipment, Bucket Elevator for Limestone has significant advantages such as compact structure, small footprint, high lifting height (up to 60 meters), good sealing (reducing dust pollution). As the mainstream model in the industry, the NE series has gradually replaced the old TB, TH and other models and become the preferred equipment for vertical conveying of limestone.

What are the types of Bucket Elevator for Limestone?

According to the physical properties and production process requirements of limestone, we provide various types of Bucket Elevator for Limestone such as NE plate chain, TH ring chain, TD belt type, etc., to ensure that each limestone material can get the best conveying solution.

NE Plate Chain Bucket Elevator for Limestone: Designed for medium and large blocks and abrasive limestone, it uses high-quality alloy steel high-strength plate chain, which is wear-resistant and reliable. There are 11 models from NE15 to NE800, with a lifting capacity of 15-800m³/h, which is the first choice for handling block limestone.

TH Ring Chain Bucket Elevator for Limestone: Suitable for powdered and small-particle limestone, it uses cast ring chain as the transmission part, has strong mechanical strength, larger lifting capacity and higher operating efficiency.

TD Belt Bucket Elevator for Limestone: Suitable for conveying small blocks and powdered low-abrasive limestone, with simple structure and stable operation, but the material temperature should not exceed 60℃ (ordinary belt) or 120℃ (heat-resistant belt)

What are the advantages of Bucket Elevator for Limestone?

Bucket Elevator for Limestone has improved the wear resistance and energy saving of the equipment according to the characteristics of limestone. The following are the specific advantages:

Wear resistance: In view of the high abrasiveness of limestone, key components are specially treated. The chain plate is made of 45# steel quenching treatment (HRC36-42), and the upper and lower sprockets are made of ZG310-570 overall quenching and tempering and tooth surface quenching (HRC40-48). The wear resistance is more than 3 times higher than that of ordinary materials. The edge of the hopper is strengthened, which greatly extends the service life in the highly abrasive limestone environment.

Energy-saving design: The inflow feeding and gravity unloading methods are adopted to avoid the high energy consumption problem of traditional digging loading. The fully enclosed casing design and optimized chain speed (0.4-1.2m/s) have no material return phenomenon and the reactive power loss is reduced by more than 30%. Compared with similar products, the energy consumption is reduced by 15-20%, and a large amount of electricity bills can be saved in long-term operation.

Superior adaptability: It can handle limestone materials in various forms, from large pieces (up to 270mm) to fine powder, from dry to slightly wet, and the temperature range covers room temperature to 250°C. The equipment has good sealing, effectively preventing limestone dust from spilling out, and making the working environment cleaner. The special anti-stuck design makes the equipment more tolerant when encountering jams caused by accidental factors, protecting key components from damage

How does Bucket Elevator for Limestone work?

Bucket Elevator for Limestone lifts materials vertically from a low place to the required height through a continuously circulating hopper. Limestone materials are evenly fed into the bottom feed port of the elevator through a vibrating feeder or chute. The hopper filled with limestone is pulled vertically up by a high-strength plate chain. During the lifting process, the middle section track prevents the chain from swinging, ensuring that the limestone material is stably lifted without spilling. When the hopper runs to the top sprocket, it uses centrifugal force or gravity to unload the material, and the empty hopper returns to the bottom along the non-working branch.

Note: The actual lifting volume is affected by factors such as limestone bulk density, particle size distribution, and moisture content.

What are the applications of Bucket Elevator for Limestone?

Bucket Elevator for Limestone can lift limestone in block (50 - 300mm), granular (5 - 50mm) and powder (less than 5mm), covering different processing states such as raw ore, crushed material and limestone powder. It has a wide range of application scenarios, including raw material and finished product transportation in cement production; lifting raw ore blocks and connecting crushing processes during mining; conveying aggregates and light calcium carbonate processing raw materials in the construction and building materials industry; lifting limestone powder in power plant desulfurization and other scenarios in the environmental protection field; as a slag-making agent conveying equipment for blast furnace ironmaking in the metallurgical industry; it can also be used for chemical raw material transportation, municipal engineering sewage treatment, etc., and can adapt to different working conditions according to material characteristics and production needs.
