hammer mill replacement hammers

The main working part of the hammer crusher is the rotor with the hammer (also known as the hammer head). The rotor consists of a main shaft, a disc, a pin and a hammer. The motor drives the rotor to rotate at high speed in the crushing chamber. The hammer head is the main wear part, and the quality of the hammer head directly affects the crushing efficiency of the crusher.

The main working part of the hammer crusher is the rotor with the hammer (also known as the hammer head). The rotor consists of a main shaft, a disc, a pin and a hammer. The motor drives the rotor to rotate at high speed in the crushing chamber. The hammer head is the main wear part, and the quality of the hammer head directly affects the crushing efficiency of the crusher. During the working period of the hammer, in addition to being impacted, it is also impacted by the material. In this way, if it is used repeatedly for a long time, the working surface of the hammer will be damaged and the surface shape will change. Most of the hammer heads of domestic hammer crushers are made of high manganese steel. The material is fed into the
machine from the upper feeding port, and is crushed by the impact, impact, shearing and grinding of the high-speed hammer. In the lower part of the rotor, there is a sieve plate, and the particle size smaller than the sieve hole size in the crushed material is discharged through the sieve plate, and the coarse particle size larger than the sieve hole size is retained on the sieve plate and continues to be hit and ground by the hammer, and finally passes through the sieve plate. out of the machine. The high wear-resistant double-alloy composite hammer has a service life of more than five times that of the original products such as manganese steel and rails, and the crushing efficiency is increased by more than 30%. The wear-resistant double-alloy composite hammer is developed by Zhangjiagang Hengxinda Company. It is the top latest technology in the industry. Its main feature is the use of two alloy liquid-liquid composites. The casting process is centrifugal pressure casting, which avoids the problems of easy falling off and no wear resistance of inlaid type. It has been used in hundreds of cement and mining enterprises. , well received by customers. The hammer head part is made of alloy steel with high hardness and high wear resistance, and the hardness can reach HRC62-65. The hammer handle part is made of high-toughness manganese steel material. Because the two alloys are compounded by metallurgical liquid, there is no need to worry about falling off. It solves the shortcomings of single alloy material with high hardness and easy breakage, good toughness and no wear resistance. Thereby greatly improving the service life and working efficiency of the hammer. High wear-resistant double-alloy composite hammer is widely used in various crushing industries such as coke, coal, coal gangue, metallurgy, glass, mining ore, limestone in cement plant, clinker, leaf rock in brick factory! Especially large single-stage hammer type Crusher shows its superiority even more.
