The Adjustable Impact Plate (also known as the Adjustable Liner Plate) is a critical wear-resistant component and adjustment part located within the core crushing chamber of an impact sand maker (or fine crusher).
Simply put, it acts as a "movable wall" inside the sand maker. By altering the distance between this "wall" and the high-speed rotating rotor (blow bars), you can directly control the discharge size, particle shape, and operational safety of the equipment.
1. Core Functions: What Exactly Does It Do?
Controlling Discharge Size (Most Critical)
The gap (opening) between the impact plate and the rotor blow bars determines the extent to which the material can be crushed.
Decreasing the gap: Increases the number of repeated impacts within the chamber, resulting in a finer discharge and a higher proportion of powder.
Increasing the gap: Allows material to be discharged more easily and increases throughput, but results in a coarser discharge size.
Application Scenario: When customers complain that "the sand is too coarse" or "there is too much stone powder," checking and adjusting this gap should be the first step.
Secondary Crushing and Shaping
After being thrown by the blow bars, the material violently strikes the impact plate, undergoing secondary crushing based on the "stone-on-iron" principle. The shape (e.g., zigzag, circular concave) and angle design of the impact plate allow the material to rebound at an angle close to 90°. This is crucial for achieving a cubic particle shape in the finished sand and effectively reducing the content of flaky and elongated particles.
Overload Protection (Yielding Function)
This is another layer of meaning behind the term "adjustable." When uncrushable materials (such as iron blocks or excavator teeth) fall into the crushing chamber, modern sand makers typically equip the impact plate with a spring or hydraulic yielding mechanism.
The impact plate automatically moves backward to widen the gap, allowing the foreign object to be discharged.
Once the foreign object is cleared, the impact plate automatically resets under the action of the spring/hydraulic system.
Value: It prevents the blow bars from breaking, the rotor from deforming, or the motor from burning out, functioning essentially as a "fuse" for the equipment.
2. Structural and Material Characteristics
Split Design:
The current trend is no longer a "single large steel plate," but rather a "base + wear block" structure.
Adjustment Plate Base: Made of tough steel, responsible for connection and adjustment.
Wear Parts: Made of high-chrome cast iron or wear-resistant alloys, responsible for impact resistance.
Benefits: When worn, only the local wear blocks need to be replaced instead of the entire large plate, reducing maintenance costs by 30%-50%.
Double-Sided / Multi-Sided Usability:
Some adjustment plates are designed with a symmetrical structure, allowing them to be flipped over and used on the other side once one side is worn. Alternatively, the blow bars can also be used on four sides, greatly improving material utilization.
Special Chamber Design:
Some impact plates are designed in an "S-shape" or "zigzag shape." The upper part handles primary crushing (large angle), while the lower part handles fine crushing and grinding (small angle). Some even feature grates (screen plates) at the bottom, allowing qualified material to pass through directly, thereby reducing over-crushing.

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.
