08/15/2024

When choosing a cement lump breaker suitable for a project site, you need to consider multiple factors, including project scale, crushing requirements, equipment performance, economic efficiency, and after-sales service.

Here are some specific selection points:

Project Requirements Analysis

Properties of crushed materials:

Cement fragments usually have high hardness and density, so you need to choose a crusher that can handle this type of material.
If the material contains a lot of steel bars or other metal impurities, you also need to consider the wear resistance and handling capacity of the equipment.

Production requirements:

Determine the amount of crushed pieces that need to be processed per hour and the required crushing particle size.
Choose the appropriate equipment type and scale based on the length of the production cycle.

Equipment Performance Evaluation

Crushing capacity:

Pay attention to the crushing ratio, processing capacity and particle size distribution of the crushed material.
The cement crusher should be able to effectively crush large cement blocks into particles that meet the requirements.

Working stability：

Choose a crusher with a stable structure and smooth operation to reduce the impact of vibration and noise on the working environment.

Wear resistance：

Considering the hardness of cement fragments, the key components of the crusher (such as blades, lining plates, etc.) should have high wear resistance.

Equipment Type Selection

Block cement lump breaker

The maximum flow rate of the model can reach 10003/H
Applicable to various gasification chutes and storage discharge outlets
Designed for material temperatures up to 120 degrees
Highly wear-resistant materials are used for crushing claws and grid plates
Easy to maintain
Integrated speed detection device (optional)
When the integrated speed detection device is selected, it is equipped with an electric control box

Crawler crusher:

Suitable for use in large projects such as field quarries and mines.
It has the characteristics of simple operation and strong autonomy, and can adapt to complex working environments.

Fixed crusher:

Suitable for use in fixed projects such as construction sites.
It has the advantages of high output and good stability, and is suitable for large-scale production.

How to solve common faults of air slide conveyor?

Darko Building Materials Machinery is a leading supplier in China, renowned for its high-quality air slide conveyor systems. Our mechanical equipment is finely crafted, quality assured, and available in various specifications. We also offer customization based on your needs and provide comprehensive technical support for our air slide conveyors.

What is an Air Slide Conveyor?

The air slide conveyor is a type of pneumatic conveying equipment used to transport bulk materials, particularly powders and granules, using air. It efficiently moves dry powdered materials, making it a popular choice in various industries.

How It Works

Airflow: The conveyor operates by forcing air through a porous surface, causing the material on top to slide along the conveyor.

Inclination: It is often installed at a slight incline to facilitate the movement of materials.

Low Energy Consumption: The system uses minimal energy compared to traditional belt conveyors, making it an energy-efficient option.

Applications

Cement and Aggregates: Commonly used in the cement industry for transporting cement, fly ash, and other fine powders.

Food Industry: Can be used for transporting flour, sugar, and other dry powders.
Chemical Industry: Useful for conveying various powdered chemicals.

Advantages

Gentle Handling: Reduces the risk of damage to delicate materials during transportation.

Dust Control: Minimizes dust generation during transport, improving workplace safety.

Space-Saving Design: Compact design suitable for limited spaces, making it easy to integrate into existing systems.

Common Blockage Causes and Solutions for Air Slide Conveyors

1.Damaged Air Permeable Layer

If the air permeable layer of the air slide conveyor is damaged, it can leak ash, causing blockages. Regularly check the air permeable layer and replace it promptly if damaged.

2.High Moisture Content

Damp materials or high humidity can block the air permeability layer. Control the moisture content of the conveyed material and frequently clean the filter at the air inlet of the blower.

3.Large Particles and Debris

Large particles and debris can slow down material movement and hinder fluidization. Regularly check and adjust the grinding grate gap. Install a slag removal device near the chute feed port to quickly clean up debris.

4.Inadequate Exhaust

Failure to exhaust the air conveying chute in time can prevent materials from suspending and fluidizing, leading to blockages. Maintain the exhaust device to ensure it remains intact and unobstructed.

5.Improper Slope

Setting the slope of the air conveying chute too low can cause blockages. A larger slope increases the flow rate of materials. For every 1% increase in slope, the flow rate increases by about 20-25%. Adjust the installation slope to maximize conveying performance.

6.Dust Accumulation

Dust accumulation in the lower shell of the chute can impede normal air supply, making fluidization difficult and causing blockages. Clean the dust regularly and check for build-up.

7.Protecting the Air Permeable Layer

To extend the service life of the breathable layer, add a feed slide at the chute’s feed port. This will prevent direct impact on the breathable layer, reducing wear and aiding material dispersion. Additionally, lay a 1mm thick porous plate on the air permeable layer near the feed inlet to further extend its lifespan.

Conclusion

Darko Building Materials Machinery combines R&D, design, manufacturing, and installation. As China’s top supplier of cement machinery and equipment, we customize solutions to meet your specific needs.

We mainly undertake desulfurization and denitrification, dust removal and environmental protection projects, and slag micro powder and powder grinding production lines. Our commitment to quality and innovation ensures that your air slide conveyor operates efficiently and reliably.
