Submerged Scraper Conveyor, Heavy Duty Chain Scraper Conveyor for Bulk Material
Advantages
1. Solid structure. It can withstand external forces such as impact, impact, smashing and pressure of coal, gangue or other materials.
2. It can adapt to the needs of uneven and bending movement of the floor of the coal mining face, and can withstand vertical or horizontal bending.
3. The body is short and easy to install.
4. It can also be used as the track for the shearer to run.
5. It can run in reverse, which is convenient for dealing with bottom chain accidents.
6. It can be used as the fulcrum of the front section of the hydraulic support.
7. The structure is simple, and the material can be fed or unloaded at any point along the conveying length.
8. the casing is airtight, which can prevent the dust from flying and polluting the environment when conveying materials.
9. When the tail is not equipped with a casing and the scraper is inserted into the material pile, it can take materials and convey them by itself.

SELECTION & TECHNICAL QUESTIONS
Q1: How do I select the right conveyor model? What information should I provide?
> To recommend the most suitable solution, please provide the following details:
> 1. Material type: What material are you conveying? (e.g., fly ash, wood chips, biomass pellets, bottom ash, etc.)
> 2. Material properties: Particle size, temperature, moisture content, abrasiveness
> 3. Capacity requirement: How many tons per hour (t/h) do you need?
> 4. Installation conditions: Conveying distance, incline angle, space limitations
> 5. Application industry: Which industry is this for? (e.g., waste-to-energy plant, biomass power plant, cement plant)
> You can also email us or contact us via WhatsApp. Our engineers will get back to you within 24 hours.
Q2: What is the difference between screw conveyors and chain conveyors? Which one should I choose?
> Both types have different applications:
> – Screw Conveyors: Best for powdery and small-grain materials (e.g., fly ash, cement powder). Good sealing performance, simple structure, low maintenance cost.
> – Chain Scraper Conveyors: Best for bulky, highly abrasive materials (e.g., bottom ash, municipal solid waste, biomass fragments). Supports multiple inlet and outlet points.
> – Bucket Elevators: Ideal for vertical or steep-incline material lifting.
> If you are not sure, tell us your material and working conditions, and our engineers will help you choose.
Q3: Can your equipment handle high-temperature materials? What is the maximum temperature?
> We can customize equipment according to material temperature:
> – Standard type: 0~80°C, carbon steel
> – Medium temperature type: 80~200°C, thickened wear-resistant liner
> – High temperature type: 200~400°C, special heat-resistant steel, optional cooling jacket
> Please tell us your material temperature, and we will recommend the most suitable material solution.
Q4: Are there any limits on conveying distance and lifting height?
> Standard design range:
> – Screw conveyor: Single section up to 70 meters; multiple sections can be connected for longer distances
> – Chain conveyor: Single machine up to 60 meters
> – Bucket elevator: Lifting height up to 50 meters
> We can also customize for extra-long distances or special angles. Contact us for detailed solutions.
Q5: Do you provide explosion-proof design?
> Yes. For explosive and flammable conditions such as pulverized coal and biomass dust, we offer:
