What Kind of Belt Conveyor is Suitable For Different Concrete Mixing Plants?

When selecting a belt conveyor for a concrete mixing plant, various factors need to be considered, including the scale of the mixing plant, material characteristics, conveying distance, inclination angle, and working environment. Here are some suggestions to help you choose the suitable belt conveyor:

Based on Production Capacity

Low to Medium Production Concrete Mixing Plants:

  • Ordinary Belt Conveyor: It has a simple structure and low cost, meeting basic material conveying needs. However, note that its load-bearing capacity and durability may be relatively limited.

High Production Concrete Mixing Plants:

  • High-Strength, Wear-Resistant Belt Conveyor: Ensures stable material conveying during peak production periods. These conveyors are typically made of high-quality materials, offering good wear resistance and load-bearing capacity.

Based on Material Characteristics

  • Heavy Materials: Choose a belt conveyor with sufficient load-bearing capacity and wear resistance to ensure materials do not damage the belt or affect conveying efficiency.
  • Lightweight, Bulk Materials: Opt for a belt conveyor with a softer, more adaptable belt material to reduce material loss during conveying.

Based on Site Conditions

  • Limited Space: Mobile or Telescoping Belt Conveyor: Provides great flexibility for mixing plants with limited space or frequent production layout adjustments. It can be easily moved to different locations to meet various production needs.
  • Spacious Site: A fixed belt conveyor can be chosen for more stable installation and higher conveying efficiency.

Type Selection

1. TD-Type Belt Conveyor

  • Introduction: The TD-type belt conveyor, especially the TD75 model, is widely used in various industrial fields for material conveying.
  • Structural Features: It has a simple and clear design, easy to maintain and operate. Belt widths are available in multiple specifications such as 500, 650, 800, 1000, 1200, and 1400 mm.
  • Application Scenarios: Suitable for industries such as mining, coal, ports, transportation, hydropower, chemicals, building materials, metallurgy, power, and material conveying in concrete mixing plants.

2. Inclined Belt Conveyor

  • Introduction: Concrete mixing plants often use inclined belt conveyors for aggregate feeding systems.
  • Structural Features: The feeding belt conveyor adopts a herringbone-patterned inclined belt conveyor. The head sits directly on the mixer, and aggregates are directly fed from the belt conveyor output. The belt conveyor installation angle is adjustable, with a streamlined process and compact structure.
  • Application Scenarios: Especially suitable for aggregate feeding systems in concrete mixing plants.

3. Troughed Belt Conveyor

  • Introduction: Troughed belt conveyors are one of the common types of belt conveyors in mixing plants.
  • Structural Features: The conveyor belt forms a trough shape, effectively preventing material from slipping and improving conveying efficiency.
  • Application Scenarios: Suitable for situations requiring inclined feeding in mixing plants, such as TD75 troughed belt conveyors with a conveying capacity of up to 1,000 tons per hour and an inclination angle of up to 30 degrees.

4. Classification by Belt Type

  • Flat Belt: Maximum angle: 25 degrees. Cost-effective, mostly used in small to medium-sized concrete mixing plants.
  • Herringbone Belt: Maximum angle: 35 degrees. Can shorten equipment footprint and increase site utilization.
  • Skirted Bucket Belt: Maximum angle: 40 degrees. Suitable when site space is limited.

Performance Parameters

  • Conveying Distance: Choose an appropriate conveying distance based on the mixing plant layout and material conveying needs. Ensure the belt conveyor can cover the entire material conveying path while avoiding excessive conveying distance that increases energy consumption and belt wear.
  • Conveying Capacity: Select a suitable conveying capacity based on the mixing plant's production capacity and material characteristics. Ensure the belt conveyor meets production needs while avoiding overload and damage due to excessive conveying capacity.
  • Conveying Speed: The choice of conveying speed should consider material characteristics and conveying distance. Appropriate conveying speed ensures material stability during conveying, avoiding material accumulation and blockage.
  • Inclination Angle: Choose an appropriate inclination angle based on site conditions and conveying needs. Generally, a larger inclination angle reduces the footprint but may affect material stability during conveying. Therefore, select an appropriate inclination angle while ensuring stable material conveying.

Materials and Quality

  • Material Selection: Belt conveyor materials should have good wear resistance, tear resistance, and corrosion resistance. High-quality materials can extend the service life of the belt conveyor and reduce maintenance and replacement costs.
  • Manufacturing Process: Choose a belt conveyor with well-crafted manufacturing, ensuring tight fitting and smooth operation between components. The quality of the manufacturing process directly affects the performance and stability of the belt conveyor.

Safety and Environmental Protection

  • Safety Protection Devices: Ensure the belt conveyor is equipped with comprehensive safety protection devices, such as emergency stop buttons and anti-slip devices. These devices can quickly stop the machine in emergencies, protecting personnel and equipment safety.
  • Noise Control: Choose a belt conveyor with lower noise to reduce its impact on the surrounding environment and personnel. At the same time, soundproofing measures can be taken to further reduce noise levels.
  • Energy Saving and Emission Reduction: Choose belt conveyor products with low energy consumption and high efficiency, complying with current environmental trends and energy-saving requirements. Optimize design and manufacturing processes to reduce belt conveyor energy consumption and improve energy utilization efficiency.

Maintenance and Servicing

  • Ease of Maintenance: Choose a belt conveyor with a simple structure and easy-to-remove and replace components for convenient daily maintenance and servicing. This helps extend the service life of the belt conveyor and reduce downtime.
  • Spare Parts Supply: Ensure sufficient spare parts supply for the selected belt conveyor to enable timely replacement and repair in case of failure. At the same time, understand spare part prices and supply channels to make reasonable procurement plans.

Brand and Supplier Selection

  • Brand Selection: Choose well-known brands and reputable suppliers to ensure belt conveyor quality and after-sales service.
  • Supplier Evaluation: Evaluate suppliers based on production capacity, technical strength, and after-sales service, selecting one that can provide comprehensive support and guarantees.

When selecting a belt conveyor for a concrete batching plant, various factors such as production capacity, material characteristics, site conditions, and equipment performance should be considered comprehensively. Through reasonable selection and configuration, ensure the belt conveyor meets production needs and operates efficiently and stably. At the same time, choosing well-known brands and reputable suppliers is also crucial for ensuring equipment quality and after-sales service.
