[Hefei, Anhui, April 2026] After three months of on-site inspections, technical solution comparisons, and multiple rounds of business negotiations, a large building materials group from Northwest China recently signed a procurement contract with Anhui Dainamu Engineering Machinery Co., Ltd. (SUHMAN) to order a complete crushing and screening production line consisting of an SE-1060 mobile jaw crusher, an SF-580D mobile impact crusher, and an SS-7018 mobile inclined screen. The project is scheduled to officially commence production in May 2026, with an expected annual ore processing capacity of 800,000 tons.
Why was SUHMAN ultimately chosen?
According to the project manager, during the procurement decision-making process, the client inspected six domestic and international crushing equipment suppliers, including several well-known imported brands and leading domestic enterprises. "We visited Dainamu's Hefei production base, toured several operational project sites, and compared technical parameters and quotations," said the client's purchasing director. "We ultimately chose Dainamu not only because the equipment performance met our requirements, but also because we recognized their professional attitude and service commitment." From the first contact, Dainamu's sales team demonstrated strong professionalism. They didn't simply push products; instead, they first understood the client's material characteristics, production capacity needs, and site conditions, and then recommended the most suitable configuration. They responded to inquiries within 24 hours, provided technical solutions and quotations within 72 hours, and even invited the client to visit the factory and operational project sites. This technology-oriented service approach made the client feel confident in their services.
Analysis of Three Core Equipment Advantages
SE-1060 Mobile Jaw Crusher – Mainstay of Coarse Crushing
As the primary crushing equipment in the production line, the SE-1060 bears the heavy responsibility of crushing large raw stones to below 200mm. This equipment uses a jaw crusher independently developed by Dainamu, with a feed opening of 1060×650mm, capable of handling stones up to 700mm in size, and a production capacity of 200-280 tons per hour, fully meeting the needs of large-scale production.
The welded frame of the equipment has undergone finite element analysis and stress relief treatment. The eccentric shaft is made of high-quality forgings, and the bearings are from SKF, with a design life exceeding 20,000 hours. The hydraulically adjustable discharge opening allows for particle size adjustment within 5 minutes. The tracked self-propelled chassis allows for relocation without a crane.
SF-580D Mobile Impact Crusher – Medium Crushing Expert
As a secondary crushing unit, the SF-580D is responsible for further crushing the jaw crusher output to finished aggregates below 40mm. This equipment adopts a heavy-duty rotor design with a linear velocity of 45m/s. The impact crushing principle produces cubic-shaped products with less than 5% needle-like and flaky particles, fully meeting the aggregate standards for high-grade highways and commercial concrete plants.
The SF-580D boasts a high crushing ratio, enabling a single unit to complete multi-stage crushing tasks. Its hydraulically assisted opening design halves the hammer replacement time. Energy consumption is 20-30% lower than traditional cone crushers, and its high-chromium alloy hammers can last 800-1200 hours. Suitable for medium-hard materials such as limestone, bluestone, and construction waste, it is highly adaptable.
SS-7018 Mobile Inclined Screen – Precise Grading
As a finished product screening device, the SS-7018 is responsible for grading crushed materials according to specifications. An adjustable inclination angle of 18° to 22° combined with elliptical vibration achieves a screening efficiency of 85-90%, exceeding the industry average. With a capacity of 150-350 tons/hour, it perfectly matches the output of the main crusher.
This screening machine supports rapid switching between single, double, and triple screen layers, with screen replacement completed within 2 hours. Various screen aperture sizes can be customized, including 0-5mm, 5-10mm, 10-20mm, and 20-40mm. The hydraulically folding side conveyor belt has a transport width of only 2.55 meters, and on-site installation can be completed within 30 minutes, meeting highway transport standards and requiring no special permits.
Service Commitment: Full-process guarantee from sales to after-sales service. On-site commissioning by after-sales engineers. After equipment delivery, Dainamu will send two senior after-sales engineers to the customer's site to provide 7 to 14 days of free commissioning service. This includes equipment installation guidance, electrical system wiring, no-load and load testing, operator training, and capacity optimization adjustments, until the customer's personnel can operate the equipment independently.
"The engineers are very professional. They not only commissioned the equipment but also taught us how to maintain it, how to determine the lifespan of vulnerable parts, and how to optimize production parameters," said the customer's production manager.
Complimentary Spare Parts: In addition to the standard warranty, Dainamu also provided the customer with an initial batch of easily worn spare parts worth approximately 80,000 RMB, including 2 sets of jaw crusher teeth plates, 1 set of impact crusher hammers, 2 sets of screening machine screens, 5 SKF bearings, 3 sets of hydraulic seal kits, and a specialized tool kit. These spare parts give the customer peace of mind during the initial operation, eliminating concerns about purchasing spare parts immediately after production begins.
Customer Testimonial: Choosing Dainamu was the Right Decision
"From initial contact with Dainamu to the final signing of the contract, the entire process was very smooth," summarized the customer's project director. "Their equipment performance is comparable to imported brands, the price is more reasonable, and most importantly, their service attitude—whether it's the sales, technical, or after-sales teams, they all demonstrated professionalism and sincerity." The customer chose Dainamu for three solid reasons: reliable products, military-grade quality standards, and key components from international brands; comprehensive service, with full support from design to commissioning to warranty; and high cost-effectiveness, with a total investment 40% lower than imported brands for the same configuration.
