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:

> – Explosion-proof motors (Ex d IIB T4 standard)

> – Reserved openings for explosion vents / rupture discs

> – Fully sealed structure to prevent dust leakage

> Please specify your explosion-proof rating requirements.

CUSTOMIZATION & MANUFACTURING

Q6: Do you support customization? What is the lead time?

> Over 90% of our equipment is customized according to customer working conditions. Standard models take about 90–120days. Special customizations take 120–180 days, depending on configuration complexity.

Q7: What material options do you offer?

> Common materials include:

> – Carbon steel (Q235B): Standard working conditions

> – Wear-resistant steel (NM400/NM500): Highly abrasive materials

> – Stainless steel 304/316L: Food, chemical, corrosion-resistant requirements

> – Bi-metal wear-resistant composite plate: Extreme abrasion conditions

> We will recommend the most cost-effective material solution based on your material properties.

Q8: What certifications do you have?

> We hold the following certifications:

> – ISO 9001:2015 Quality Management System

> – ISO 14001 Environmental Management System

> – ISO 45001 Occupational Health & Safety Management

> – CE Certification (EN 1090 Steel Structure)

> If you need scanned copies of specific certificates, please contact us.

DELIVERY & LOGISTICS

Q9: Which countries do you export to? Do you have export experience?

> Our equipment has been exported to more than 20 countries worldwide, including:

> – Europe: Germany, France, Poland, Turkey, etc.

> – Southeast Asia: Singapore, Thailand, Indonesia, Vietnam, etc.

> – Middle East: Saudi Arabia, UAE, etc.

> – South America**: Brazil, Chile, etc.

> We are familiar with the full export process: packaging, customs declaration, and ocean freight. We can provide FOB, CIF, and other trade terms.

Q10: What is your packaging method? Is it suitable for long-distance ocean shipping?

> Export-standard packaging:

> – Large items / complete machines**: Rust prevention + waterproof film + fumigated solid wood pallet

> – Precision components: Wooden case with shock-absorbing filling

> – Random accessories: Categorized packing with detailed packing list

> All wooden packaging meets IPPC fumigation standards for direct customs clearance.

Q11: What is your minimum order quantity?

> We do not have a strict minimum order quantity. Single-unit orders are welcome. Bulk orders can enjoy more favorable pricing.

INSTALLATION & AFTER-SALES

Q12: Do you provide installation guidance? Do engineers need to come to site?

> We offer two service options:

> 1. Remote guidance: Detailed installation drawings and operation manuals, video guidance for installation (free of charge)

> 2. On-site service: Dispatch engineers to site for installation and commissioning (travel costs are additional)

> Most customers choose remote guidance. Our equipment is designed as a modular structure for easy installation.

Q13: What is the warranty period? What are the wearing parts?

> Standard warranty period is 12 months (from the date of arrival at port).

> Wearing parts list:

> – Chain / screw flights: Approximately 1–3 years, depending on material abrasiveness

> – Liners: Approximately 2–4 years

> – Bearings: Approximately 2–3 years

> We recommend ordering a wearing-parts spare kit together with your first order.

Q14: How do you solve problems during operation?

> We provide 7×24 technical support:>

> – Response within 24 hours for technical issues

> – Remote video troubleshooting guidance

> – Engineer on-site service when necessary

> – Common spare parts in stock for fast delivery

QUOTATION & COOPERATION

**Q15: How can I get a quote? How long does it take?

> Quotation process:
