Hammer crusher rotor assembly hammer head configuration method:
Friends who have visited our factory know that there are two different styles of hammer crusher, respectively, the traditional hammer crusher (hereinafter referred to as the hammer crusher) and the impact hammer crusher, from the respective mechanical rotor assembly point of view, the most obvious feature is the suspension of high chromium alloy hammer head and the number are not the same. Today, we mainly talk about the configuration method of the hammer head of the rotor assembly of the hammer crusher produced by Shandong Sanxiang Heavy Industry Machinery, so that you can figure out its working principle.
The overall policy of high chromium alloy hammer crusher is to be relatively symmetrical, so that its rotor can form a sealing ring when rotating at high speed. Why is it relatively symmetrical? Before explaining this problem, let's first explain the working principle of the hammer crusher: The rotor disc with the hammer head is driven by the motor to drive the hammer head to do high-speed circular movement. When the material enters the crushing chamber, it is hit by the high-speed rotating hammer head, and the material is broken after the impact of the high-speed shooting to the counterattack plate and the friction impact between the high-speed flying materials. The materials that meet the particle size requirements are discharged from the specified sieve hole. After a crushing and the particle size does not meet the requirements of the material, with the new material is broken again by the hammer head. When large materials enter the crushing chamber, the pre-placed load rod is blocked in the upper part of the crushing chamber, to be broken into small and medium-sized materials and then fall into the lower crushing chamber, to prevent other working parts from being damaged when large materials enter the load surge, which is safer and more stable crushing.
Because the rotor of the hammer crusher is equipped with a load bar, it mainly plays an overload protection role, which makes the hammer broken rotor only need to adopt a relatively symmetrical strategy when mounting the hammer head, and there is no need to hang all the gaps with the hammer head. For example, if you are like the PC1614 hammer crusher model produced by Shandong Sanxiang Heavy Industry Machinery, the hammer head of the rotor is matched in a 4-2-4-2 way, that is, the four hammer shafts of the rotor, two of which are opposite to hang four hammer heads, and the other two groups only hang two hammer heads. The frame of the fork is formed between the relative 4-2 hammer heads, and the other is well complementary.
There is no gap between the hammer plate and the hammer head, and Shandong Sanxiang Heavy machinery uses the way of loading the hammer ring to protect the hammer shaft from the high-speed impact of broken materials. The hammer ring is generally cast of wear-resistant high manganese steel, durable.
In the actual production process, the hammer head forms a relatively closed ring with the high-speed rotation of the rotor, which can well protect the outer protective layer of the large shaft and indirectly protect the service life of the machine's large shaft. At the same time, the hammer crusher rotor assembly produced by Shandong Sanxiang Heavy Industry machinery has the overload protection effect of the load bar, and the relatively symmetrical mounting method similar to 4-2-4-2 is scientific and reasonable, relatively reducing the overall quality of the rotor, and also reducing the replacement cost of the hammer head for future maintenance.
Shandong Sanxiang Heavy Industry Co., Ltd. has a certain reputation in the industry in Shandong crusher manufacturers, the production of hammer crusher rotor assembly of high chromium alloy hammer head using a relatively symmetrical configuration scheme, through the actual production test is scientific and reasonable. Minimizing the mounting of the hammer can reduce the overall weight of the rotor assembly, indirectly reduce the production energy consumption and customer maintenance costs, thereby further improving the market competitiveness of Shandong Sanxiang Heavy machinery related products.
