What Are The Wearing Parts Of VSI Crusher?

    VSI Crusher (Vertical Shaft Impact Crusher) is the core equipment of the stone sand making production line. Since the crushing ratio of VSI sand making machine is higher than other Stone Crushing Equipment, the wear of its wearing parts will be relatively higher.

    Using high-quality accessories, reasonable maintenance, and timely replacement of spare parts can effectively improve the service life and production efficiency of VSI crushers.

    The vulnerable parts of VSI sand making machine mainly include flow channel plate, impact block, throwing head, wear-resistant plate, impeller assembly, peripheral guard plate, etc. Since these parts will be in direct contact with the material, the wear will be more serious.

♦♦ 1. Blade

    The cutter head is one of the core working parts of the sand making machine, also known as the wear-resistant block or throwing head. It is mainly used for throwing and crushing materials. It is usually made of carbide material. It has higher reliability, wear resistance and better impact performance, and can achieve continuous cutting, bending, welding, etc. The specifications of the cutter head need to be customized according to the model of the sand making machine. The K-shaped cutter head has higher working efficiency and effect.

    When the wear on one side reaches 15mm or the chipping is more than 10mm, it needs to be replaced.

♦♦ 2. Impeller Assembly

    The impeller assembly is the key crushing component of the sand making machine and is installed on the main shaft assembly. A tapered sleeve and key connection are used to achieve the purpose of transmitting the button spacing. It is also equipped with a flow channel plate and a distribution cone, whose main functions are to accelerate and evenly distribute the materials entering the crushing chamber of the sand making machine and discharge them using the emission flow channel, which helps to crush the materials.

    As a key component of the sand making machine, the impeller is not only important but also relatively fragile. All material ejection is done in the impeller. Therefore, the operation of the sand making machine must be carried out according to the instructions, otherwise the impeller will easily be worn, causing various faults of the sand making machine, reducing production efficiency and service life.

♦♦ 3. Runner Plate

    The flow channel plate is installed in the rotor, and its main function is to transfer the high-speed moving materials in the impeller and lead them out of the impeller sand making machine when working. It includes a flow channel plate body and a cemented carbide or ceramic composite layer attached to the flow channel plate body. The composite layer is used to make the flow channel plate body have a deeper thickness and protect the flow channel plate to prevent the flow channel plate from wear and cracking during high-intensity work.

    There are usually three types of flow plates: forward flow plates, reverse flow plates and radial flow plates. The specific number of channel plates depends on the diameter of the matching impeller and the feed particle size of the material to be crushed.

    By properly maintaining the wearing parts of the VSI sand making machine, its service life can be increased by more than 40% and the comprehensive operation and maintenance costs can be reduced by 25%.
