How to make the wear parts of the crusher last longer
October 8, 2023 Hawk
First of all, we should understand what wear parts the crusher has. Based on the changes, upgrades and usage of all types of rock crushers over the years, it can be concluded that the wear parts of the crusher have the following types:
① Crushing plate: The crushing plate is the main wearing part of the crusher, and its main function is to crush materials. During the crushing process, the crushing plate gradually wears due to the impact and friction between the material and the crushing plate. ② Hammer head: The hammer head is an important part of the crusher. Its main function is to impact and crush materials through high-speed rotation. During use, the hammer head will wear due to impact and friction. ③Bearing: Bearing is an important part of the crusher, and its main function is to support the operation of the crusher. During use, bearings will wear due to friction and overheating. ④Rotor: The rotor is the main component of the crusher, and its main function is to drive the operation of the crusher. During use, the rotor will wear due to friction and impact. ⑤Screen: The screen is an important part of the crusher, and its main function is to screen the crushed materials. During use, the screen will wear due to the impact and friction of materials.
In order to solve the problem of the life of crusher wear parts from the root cause, we must also understand what materials the crusher wear parts are made of.
The following materials are usually used as the best raw materials for the production of various types of crusher wear parts: ① High manganese steel: This is a very commonly used material for crusher wear parts, mainly used to manufacture crushing plates and hammer heads. High manganese steel has good toughness and wear resistance, and can effectively resist the impact and friction of materials. ②Chromium cast iron: This material has very good hardness and wear resistance and is often used to manufacture high-hardness and high-wear wear parts of crushers, such as hammer heads and crushing plates. ③Alloy steel: This material also has very good hardness and wear resistance and is often used to manufacture bearings and rotors. The advantages of alloy steel are good wear resistance and long life, but the cost is relatively high. ④High chromium cast iron: This material has very good wear resistance and hardness and is often used to make screens. The advantage of high chromium cast iron is good wear resistance, but the cost is relatively high.
The above knowledge is all we need to study how to extend the life of the wear parts of the crusher. Next, based on the research results, we will tell you how to truly extend the service life of these parts from the physical level.
Speaking of wearing parts, as the name implies, everyone knows that they must be parts with a very large amount of wear and contact. The materials used in the production of these parts must be very hard carbide materials, but it still cannot prevent the wearing parts from breaking, so We have to consider how to extend its life from many aspects.
Depending on actual usage, wear parts are usually replaced directly rather than repaired. But when you know that replacing a new one costs $10,000 and repairing it costs less than half that, how do you choose? But at this time you may have questions, can the lifespan after repair be compared with the new one, and a series of other questions. So if professionals tell you that the repair life is better than the new one, then should we just focus on the new product? It’s time to adopt this technology!
There is a brand-new reinforcement technology called laser cladding technology. Unlike the traditional application of a layer of wear-resistant coating on the surface of the product, it will actually add a layer of stronger wear-resistant alloy with visible thickness to the surface of the product. layers, created by laser and alloy metal powders. Its hardness can match the casting process. For crusher users, if they choose new wear parts reinforced with this laser cladding technology from the beginning, they can reduce their cost investment by 30%-50% in the future use process.
In the face of new high technology, it not only improves the life of wear parts, but also reduces the cost of use. This is really good news for crusher owners.
