The key to improve the anti-wear performance of jaw crusher and gyratory crusher liner
What is the key to improving the anti-wear performance of jaw crusher and gyratory crusher liner?
Jaw crushers and gyratory crushers are mostly used for coarse crushing of raw ore in mining. Coarse crushing is the first process of raw ore crushing. The jaw crusher and gyratory crusher used for coarse crushing are relatively heavy-duty machines. Mining enterprises crush the mined raw ore into a size suitable for transportation and supply to secondary and tertiary crushers through jaw crusher or rotary crusher. Jaw crusher and gyratory crusher have strong crushing effect and high crushing efficiency, so most metal mines mainly use these two types of crushers. After long-term use, the jaw crusher plate and the gyratory crusher liner will wear to a certain extent and need to be replaced. The quality and service cycle of the jaw crusher plate and the gyratory crusher liner lie in their anti-wear performance. What is the key to improving anti-wear performance? Hunan Xiangjian Machinery will explain it to you below.
1. Tooth plate of jaw crusher
In the periodic work of the jaw crusher, the tooth plate is periodically loaded and unloaded, and must have sufficient strength. At the same time, the tooth plate is immersed and deformed by high-hardness ore, resulting in fracture and sliding grinding, resulting in ploughing groove marks. , and even dropped blocks. Usually, the tooth plate is bolted to the cast steel plate by the high manganese steel lining plate. After a period of use, the high manganese steel liner can be turned around for use or replaced. The high-manganese steel material itself has an impact-resistant layer that is hardened on the surface due to impact. This mainly depends on the element ratio of the material. Most of the quality is not durable due to insufficient element ratio.
2. Gyratory crusher liner
During the operation of the crusher, the lining plate is chiseled and worn by the large impact energy. The gyratory crusher liner material is also required to have high strength and wear resistance. Rolled mortar wall lining is made of high manganese steel or reinforced nickel-chromium white cast iron, and broken wall lining is made of high manganese steel. The lining plate is chiseled and worn by the large impact energy, and the surface of the high-manganese steel lining plate can be hardened after being impacted, so the lining plate is mostly made of high-manganese steel.
We understand the wear resistance principle of jaw crusher plate and gyratory crusher lining plate. The main reason is that they are made of high manganese steel and have strong wear resistance, but there are many high manganese steel materials with short service life. This is because their element ratio is not enough or does not reach the appropriate ratio, then the real reason for the insufficient element ratio lies in the casting process of the manufacturer, some in order to save costs and reduce the input of raw materials, and some are due to the low level of their own craftsmanship, so when purchasing We must choose a manufacturer with strong strength, good production and casting technology, and good quality products to cooperate. Hunan Xiangjian Machinery is an old manufacturer for decades and a member of Alibaba's integrity pass for eleven years. The water glass sand mold process is adopted. , The wear resistance of the produced jaw crusher and gyratory crusher has been greatly improved, and the quality is generally higher than that of similar products in the market.
