What anti-corrosion and weather-proof treatments are provided for outdoor mine silos?

The whole silo undergoes sandblasting rust removal first. Then multi-layer coating: epoxy anti-rust primer + intermediate anti-corrosion paint + outdoor polyurethane topcoat. The coating has strong ultraviolet resistance and rainwater erosion resistance, adapting long-term outdoor open-air working environment of mines.

AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company with substantial manufacturing equipment, a 30,000-square-meter workshop, and stated lifting, machining, heat-treatment, and welding capabilities. It holds ISO9001, ISO14001, ISO45001, ASME U stamp, and NB certifications according to the company description, while another record specifically confirms ISO9001:2015. Service procedures for supplier assessment, corrective actions, and customer complaints are documented and followed, but no approved-supplier list is maintained. The supplier offers extensive customization and ODM services, although it reported no new products in the past year and no available SDK. Export activity is material, with 51%–70% of sales from exports, supported by experienced export staff, but it has no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Financial credibility cannot be determined because the provided records contain only years, not financial results or indicators.

Supplier typeThe supplier is explicitly classified as a "Combined" company. The record also describes broad offerings spanning general information, export trade, manufacturing, service, quality control, R&D, and sustainability, supporting a diversified supplier profile.

CertificationsThe company description states possession of ISO9001, ISO14001, ISO45001, ASME U stamp, and NB certification; ISO9001:2015 is separately recorded as a management-system and sustainable-development certification. These records provide explicit evidence of multiple certifications, although the detailed description does not specify validity dates or scopes.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and for handling customer complaints. However, it has no overseas warehouse, showroom, overseas agent or branch, and no offline trade-show participation, indicating limited stated overseas service infrastructure.

Production capacityThe supplier reports a 30,000-square-meter workshop, one production line, a 280-ton single-workshop lifting capacity, large bending and turning equipment, a heat-treatment furnace, and automatic welding machines. Finished-product inspection instructions are uniformly followed, but continuous quantity reconciliation for each batch or production volume is not performed.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization through both design and R&D services. It also offers ODM service, demonstrating broad stated customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands and has collaborated with Fortune 500 companies. These are explicit customer-related credentials, although no customer names, project details, product scope, or performance outcomes are provided.

Product Q&A

Q:What bulk powder materials can this vertical silo store?

It is specially customized for mine fly ash, and also widely applicable to cement powder, mineral powder, limestone powder, feed powder and other dry bulk powdery materials. All stored materials are kept sealed without dust leakage.

Q:What is the structure advantage of vertical silo compared with horizontal silo?

1. Small floor space, high space utilization, suitable for mine and factory limited site; 2. Gravity self-discharging design, no extra conveying equipment required for discharging, lower operation power consumption; 3. Fully enclosed vertical cylinder structure, effective rainproof and moisture-proof, prevent fly ash caking; 4. Convenient centralized dust removal, easy environmental protection emission compliance.

Q:Can the silo be customized in volume and size? Whats the volume range?

Yes, full customization supported. Available volume ranges from 50m to 3000m. Silo height, diameter, cone angle can be adjusted according to customers fly ash output, site space and loading/unloading mode. Vertical single silo or multi-silo group layout are both optional.

Q:What steel materials are adopted for mine fly ash silos?

Main body adopts Q235B carbon steel plate with good structural strength. For fly ash with high humidity and corrosive components, we can upgrade to weather-resistant steel or add internal anti-corrosion coating. All steel plates come with original mill test certificates.

Q:Does the silo have anti-blocking design for fly ash discharging?

Yes. The bottom cone adopts large inclined angle design to reduce powder adhesion. Optional supporting devices: air fluidization plate, vibrator, arch breaking air cannon. These devices effectively break material arching and blockage, ensuring smooth continuous discharge of fly ash and feed powder.
