Question 1

What materials can your vacuum conveying systems handle?

Accepted Answer

Our systems transfer powders, granules and bulk solids such as flour, sugar, milk powder, pigments, resins, battery cathode/anode powders, pharmaceutical excipients and chemical additives. Final selection depends on particle size, bulk density, moisture, abrasiveness and explosibility.

Question 2

How do I choose between vacuum conveying and pneumatic conveying?

Accepted Answer

Vacuum conveying is ideal for short-to-medium distances, hygienic indoor transfer and flexible routing into mixers or packers. Dense-phase or long-distance pneumatic conveying is better for outdoor silo transfer, abrasive products or higher capacities. Share your material, distance and throughput and we will recommend the right approach.

Question 3

Do you provide customized system design?

Accepted Answer

Yes. Every powder handling line is engineered around your material, capacity, plant layout and hygiene requirements. We supply equipment selection, layout drawings, automation options, documentation and commissioning support.

Question 4

What information do you need for a quotation?

Accepted Answer

Please provide material name and bulk density, required capacity (kg/h or t/h), conveying distance and height, number of pickup and discharge points, utilities available, and any hygiene or ATEX requirements. Photos or layout sketches help us respond faster.

Question 5

What materials of construction are available?

Accepted Answer

Product-contact parts are commonly stainless steel (304 / 316L) for food, pharma and battery applications. Carbon steel and wear-resistant options are available for industrial minerals and abrasive powders. Seals and filters are selected for the process duty.

Question 6

Can systems integrate with existing mixers, packers or extruders?

Accepted Answer

Yes. Receivers, rotary valves and screw feeders can discharge into existing equipment. We also supply central feeding networks that refill multiple machines from shared intake points.

Question 7

Do you offer installation and commissioning?

Accepted Answer

We provide installation guidance, remote support and on-site commissioning depending on the project scope. Spare parts lists, operation outlines and training materials are included with equipment delivery.

Question 8

What is the typical lead time?

Accepted Answer

Lead time depends on system complexity and customization. Standard equipment is often faster; complete engineered lines require design, fabrication and testing. We confirm schedule with each quotation.

Question 9

Do you export internationally?

Accepted Answer

Yes. CHUYAO Powder Engineering supplies systems and spare parts to customers worldwide, with English-speaking engineering support for selection, documentation and after-sales service.
