In Vertical Shaft Impact (VSI) crushers, the upper and lower flow channel liners are critical wear parts installed inside the high-speed rotating impeller (rotor). They form the channels through which material moves within the rotor, directly determining the crusher's operational efficiency and service life.
1. Core Functions and Working Principle
Guiding Material Flow: Their primary function is to guide the stones to move smoothly through the crushing chamber and inside the rotor. After the material drops from the center, it is systematically directed toward the edge of the rotor through the channels formed by the upper and lower flow channel liners.
Facilitating High-Speed Ejection: The flow channel liners deliver the material steadily to the rotor outlet. Working in conjunction with the main wear blocks (rotor tips), they accelerate and eject the material into the crushing chamber, facilitating the "rock-on-rock" or "rock-on-iron" crushing process.
Protecting the Rotor Body: During the high-speed scouring and friction of the material, the flow channel liners act as sacrificial parts, effectively protecting the core rotating components (the impeller/rotor) from direct wear and damage.
2. Materials and Manufacturing Processes
Since they are located inside the high-speed rotating rotor and subjected to massive centrifugal forces and intense material friction, the upper and lower flow channel liners must possess extremely high wear resistance and impact toughness.
Common Materials: They are mainly cast from high manganese steel (such as ZGMn13), high-chromium cast iron, high-chromium alloy steel, or high-chromium cast steel.
Manufacturing Processes: They are typically produced using V-process, lost foam, or sodium silicate sand casting processes. Some high-end products employ inlaid composite casting technology to maximize wear resistance while ensuring impact toughness.

The mainframe is designed for continuous heavy-duty operation. Wear parts such as jaw plates, liners and blow bars are made of high-manganese steel or alloy materials, and their service life depends on the material hardness and working hours.
Every machine goes through material inspection, machining inspection, assembly and a full no-load test run before shipment. Inspection records and test videos are provided to customers.
Warmly welcome. You can visit our manufacturing base in person, and remote video inspection is also available for customers from overseas.
Yes. Package orders of a full line or multiple machines usually receive a more favorable price and priority in the production schedule.
Large mainframes are shipped by sea in containers or bulk vessels; smaller machines and spare parts go by container, air freight or international express, with full packaging for moisture and rust protection.
