In Vertical Shaft Impact (VSI) crushers, the slide plate is a critical wear part in the equipment's feeding and material distribution system. It is typically installed below the feed hopper or inside the crushing chamber, serving as a buffer and guide to connect the feeding and crushing processes.
1. Core Functions and Working Principle
Guiding Material Flow and Impact Buffering: As the stones fall vertically from the central feed inlet of the crusher, the slide plate acts as a receiving surface. It changes the flow direction of the material, guiding it to slide smoothly into the rotor or crushing chamber. Simultaneously, it effectively buffers the direct impact and wear on the equipment's shell and inner walls.
Optimizing Ejection Trajectories: In VSI crushers, the angle design of the slide plate (typically forming a 35° to 70° angle with the horizontal plane) is crucial. An appropriate angle ensures that the material gains sufficient tangential velocity as it slides down, allowing it to collide efficiently with the high-speed material stream ejected by the rotor, thereby achieving the "rock-on-rock" crushing effect.
Forming a Self-Lining Material Protection: During operation, a layer of crushed material (material lining) accumulates on and around the surface of the slide plate. Subsequent falling material directly impacts this material lining rather than the metal component, which significantly reduces mechanical wear and iron contamination.
2. Materials and Manufacturing Processes
Since the slide plate is subjected to continuous scouring, friction, and intense impacts from high-hardness stones over a long period, it must possess extremely high wear resistance and impact toughness.
Common Materials:
High-Chromium Alloy / High-Chromium Cast Iron: Features extremely high hardness (Rockwell hardness of 60HRC and above) and excellent wear resistance, making it the mainstream choice.
High Manganese Steel (e.g., ZGMn13): Possesses exceptional impact toughness. Its surface undergoes work hardening when subjected to intense impacts, thereby enhancing its wear resistance.
ZTA Ceramic Composite Material: High-end products utilize Zirconia-Toughened Alumina (ZTA) ceramics, which offer wear resistance more than 10 times that of high manganese steel. This greatly extends service life and reduces the frequency of downtime for replacements.
NM Series Wear-Resistant Steel (e.g., NM400): Achieves high hardness through heat treatment, making it suitable for chute liners operating under medium-to-high impact conditions.
Manufacturing Processes: They are typically produced using V-process, lost foam, or sodium silicate sand casting processes. For products designed for extreme operating conditions, a chromium carbide (Cr3C2) wear-resistant layer is often plasma-welded onto the base material, or inlaid composite casting technology is used for localized reinforcement.

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.
