The heavy hammer crusher is an upgraded product of the hammer crusher. The heavy hammer crusher is a veritable rough crusher, often used in the primary crushing link in the sand and gravel production line.After rough crushing by the heavy hammer crusher, the ore with low hardness basically changes from a large piece to a medium or even lower particle size, and even directly meets the particle size requirements of the finished product, which is deeply loved by users.This article is about how to calculate the speed of the heavy hammer crusher that users are more concerned about, how much is appropriate, and popularize it for everyone.
What is the appropriate breaking speed for a large heavy hammer?
The speed of the heavy hammer crusher is also the speed of the rotor, and its main working part is the rotor with a hammer (also known as a hammer head). The rotor is composed of a main shaft, a disc, a pin shaft and a hammer. The motor drives the rotor to rotate at high speed in the crushing cavity. The material is fed into the machine from the upper feeding port, and is crushed by the impact of the high-speed moving hammer.
The rotor speed of the heavy hammer crusher can be designed according to the circumferential speed. The specific calculation method is: n=60/(πD), where v is the circumferential speed of the rotor (m/s), and D is the diameter of the rotor (m) . The peripheral speed of the rotor generally ranges from 18 to 70 m/s, and the peripheral speed of the rotor of a small crusher is between 25 and 70 m/s, so the rotor speed is 750 to 1500 r/min; for large crushers, its speed is in 200~300r/min.
Is the rotor speed of the hammer crusher higher or lower?
This machine has a large crushing ratio, which can save the initial crushing process of the jaw crusher, realize the crushing of large and small materials at one time, and the product has a uniform and complete grain shape, and the processing capacity is in the range of 100-3000t/h.These are all thanks to the hammer head driven by the rotor under high-speed operation, and the material can be processed.
Therefore, the speed of the hammer crusher affects the output and crushing effect.
Generally speaking, the higher the speed of the rotor, the smaller the particle size of the product and the higher the output. Of course, there are disadvantages, such as the faster the wear of the hammer, the grate and the liner, and the higher the power consumption.
Therefore, the circumferential speed of the rotor should be as low as possible under the premise of ensuring the output and the particle size of the finished product.
