Wear Resistant High Impact Screw Flight Liner For Vertimill 

Product Description

Tower mill spiral tip liner is the core wearable protective casting installed on the spiral end of vertical tower grinding mill. During continuous fine grinding work, it keeps direct contact with grinding media and crushed mineral ore, enduring persistent high abrasive wear and cyclic impact loads. It prevents the spiral structure from rapid erosion and deformation, maintains the clearance of the grinding chamber and stabilizes grinding efficiency. Our foundry specializes in high performance heavy duty castings for mining equipment. We supply castings made from high manganese steel high chromium alloy steel alloy steel and ductile iron. Our main product range includes ball mill liners jaw crusher wear plates AG mill liners and SAG mill liners. We support full customization according to customer drawings sample measurements and actual mine working conditions. Different material options can be selected to match various abrasion and impact environments, extend service life, reduce frequent replacement work and cut maintenance and production downtime for mineral processing plants.

Applications

This tower mill spiral tip liner is widely used in vertical tower fine grinding mills of mineral concentrators. It serves for fine grinding and ultra fine grinding processes of gold ore copper ore iron ore lead zinc ore manganese ore nickel ore and multiple non metallic minerals including feldspar quartz and limestone. It is applicable for mines with wet grinding or dry grinding conditions. The liner fits for concentrator projects with medium and fine particle size reduction requirements. It is commonly adopted in small scale mine plants and large scale mineral processing projects. Besides ore grinding, it can also be used in metallurgical slag grinding and industrial raw material fine milling. It protects the spiral assembly against severe material abrasion and guarantees continuous and stable production operation.

Production and Quality Inspection

We implement full lifecycle quality management starting from raw material melting to finished casting delivery. After casting forming, workpieces are processed by professional heat treatment to optimize internal grain structure and balance hardness and toughness for superior wear resistance and impact resistance. Every batch undergoes a complete set of strict inspection procedures including chemical composition analysis hardness test dimensional inspection metallographic analysis 3D scanning MT magnetic particle testing and UT ultrasonic testing. 3D scanning checks the overall contour of the casting and compares it with digital design model to ensure shape accuracy. MT magnetic particle testing detects tiny surface cracks and defects. UT ultrasonic testing inspects internal hidden defects inside thick casting sections. All inspection records and test reports can be provided for customers to review, to ensure the finished liners fully meet technical specifications and acceptance standards.

Support and Services

We provide end to end professional service for mining wear resistant castings. Our technical team can assess site working conditions, analyze ore abrasiveness and impact level to recommend the most suitable material grade and optimize liner structure. We accept OEM and ODM custom orders. We can reverse engineer products based on physical samples or field measurement data. We provide professional technical consultation before order confirmation. During production we keep customers updated on manufacturing progress. We supply installation suggestions and daily maintenance guidance. We handle both small trial orders and large bulk orders. We can adjust production schedule to match customers project timeline. We offer after sales follow up and respond quickly to technical problems arising during product application.

Packing and Shipping

Finished spiral tip liners are fixed firmly on heavy steel support frames using steel strapping. Protective padding is applied on machined fitting surfaces to avoid scratches and collision damage. Solid wooden case packaging is available upon customer request. We can deliver goods to designated port or warehouse. We support multiple international trade terms including FOB CIF and FCA. We prepare complete commercial documents for customs clearance. We arrange sea transportation and track shipment status to ensure safe delivery.
