Russian Mining Operator Orders Third Set of Strudex SAG Mill Cone Liners After Exceptional Field Performance

Hengshui, China – Strudex Technology Co., Ltd., a Chinese manufacturer of rubber wear-resistant products for the mining industry, has received a third consecutive order from a Russian mining customer for ceramic-reinforced SAG mill discharge cone liners—following nearly 12 months of successful operation that has exceeded the customer's performance expectations.

The customer, a Russian mining equipment and wear materials supplier, approached Strudex in February 2025 with a specific requirement: produce a ceramic-lined discharge cone for a SAG mill. The customer provided detailed design drawings and tasked Strudex with bringing the design to reality.

From Design to Production

Strudex's engineering team manufactured the metal support structures and rubber lining panels according to the customer's specifications. Prior to shipment, the company conducted a pre-delivery trial assembly of the liners to verify fit and alignment—a standard practice that ensures components meet dimensional requirements before they reach the customer's site.

By late July 2025, the customer confirmed that the liners had been successfully installed. The customer reported that Strudex had maintained exceptionally tight dimensional tolerances throughout production, resulting in minimal installation gaps between adjacent liner panels—a critical factor for preventing material ingress and ensuring long-term liner performance.

Performance Validated in Operation

Two months into operation, the customer provided the first on-site performance feedback. The mining end-user was sufficiently impressed with the cone liner's performance to plan the purchase of an additional set as a spare.

At the eight-month mark, the customer reported that the first set of liners remained in good condition, with the rubber and ceramic components showing no signs of premature wear. The customer subsequently ordered a second additional set—the third set in total—to expand their spare parts inventory.

After nearly 12 months of continuous operation, the customer delivered the most significant validation yet: the mining operator is extremely satisfied with the cone liner's performance and has scheduled the replacement of the first set at the 18-month operational milestone.

Technical Excellence Drives Repeat Business

The case demonstrates several key strengths of Strudex's manufacturing capabilities:

Precision Engineering. The tight dimensional control achieved during production allowed for near-flawless installation, with minimal gaps between liner panels—a critical factor for preventing material ingress and extending service life.

Durable Material Selection. The combination of high-grade rubber with ceramic inserts in the discharge cone design has proven its durability in continuous SAG mill operation, with the first set still performing reliably after nearly 12 months.

Custom Manufacturing. Strudex's ability to manufacture to customer-provided specifications, including complex ceramic-reinforced designs, demonstrates the company's engineering flexibility and production capability.

Quality Assurance. The pre-delivery trial assembly process ensured that all components met dimensional requirements before shipment, eliminating installation delays and ensuring a smooth start-up.
