Why can't customized high chromium alloy crusher hammer change the technical parameters at will?
As a stone crusher mill machine parts manufacturer in Linyi, Shandong, Shandong Sanxiang Heavy Industry Co., LTD., in the actual sales process, many customers want to change the requirements of crusher parts, the purpose is nothing more than to improve the wear resistance of relevant parts or to meet their special production requirements. In the face of similar problems, can not say that can not be changed, the need for specific problems specific analysis, some accessories can be appropriately modified, some can not be changed, need to be clear with the customer.
The high chromium alloy hammer head used above the hammer crusher often encounters such problems. We sum up there are two main categories, one is to increase the weight and thickness of the hammer head to increase the wear resistance and service life of the hammer; The second is to improve the length of the hammer handle part to meet the special production needs of customers, such as the production of machine-made sand.
In this, I want to explain a problem to you, that is, the technical parameters of the hammer crusher mill machine produced by Shandong Sanxiang Heavy Industry Co., Ltd. are repeatedly verified. The weight of the hammer head, the length of the hammer handle should be designed, how thick the wear-resistant leakage plate is, and how thick the hammer shaft is, all have their theoretical data. Within a reasonable scope, appropriate modifications can be made, but they must not exceed the theoretical value. As for what harm, let me explain to you with actual examples.
Taking the hammer crusher of the PC1614 model as an example, the standard configuration of our machine is 320 under the hole, a single weight of 58 kg of high chromium alloy hammer head, the hammer shaft is 90mm thick, the thickness of the wear-resistant leakage plate is 8-9 cm, and the thickness of the straight plate is 9-10 cm. When the customer orders the machine, if any customer wants to change the relevant technical parameters, we will inform them in advance of the negative impact, first of all, the supply of accessories in the later period, and second, if the modification is made according to the customer's requirements, and if there is any problem due to the modification of the design of accessories, our stone crusher machine company will not assume the relevant maintenance responsibility.
After one of our customers purchased our PC1614 hammer crusher mill machine, without our knowledge, he went to a foundry to modify the shape size of the hammer head and greatly increased the weight of the hammer head. This does improve the service life of the hammer head to a certain extent, but after a period of use, the hammer disc above the crusher rotor assembly has appeared traces of fracture. After they were repaired several times, the last several hammer disks on the rotor were completely abandoned, the reason is that the stone crusher alloy hammer head is too heavy to bear the upper limit of the hammer disk and then damaged.
To give a simple example, is to let everyone understand that the machine design is generally a technical work, it is necessary to repeatedly demonstrate how to design and produce each machine part, so that each part in the actual production process as far as possible to achieve a dynamic balance, and privately modify the size of the relevant accessories will inadvertently break this balance. This can lead to many unexpected machine failures.
The technical parameters such as the weight and length of the high chromium alloy crusher hammer head configured on various models of hammer crusher of Shandong Sanxiang rock crusher machine factory have been repeatedly verified by the technical department and the casting workshop, which can be basically said to be more reasonable. If the hammer head is deliberately aggravated, the light will cause the hammer disk to break, and the heavy will damage the motor and bearings. If you deliberately lengthen the length of the hammer handle, it will increase the chance of the crusher's alloy hammer head breaking the arm, causing hidden dangers to the safety of the actual production, all such practices are not desirable to tell the truth.
To sum up: as a stone crusher parts manufacturer with many years of production experience, the relevant technical parameters of the high chromium alloy hammer produced by Shandong Sanxiang Heavy Industry Co., Ltd. are verified by various aspects of production practice, and are basically scientific and reasonable. In the face of many customers want to make some modifications to the high chromium alloy hammer produced by Shandong Sanxiang stone crusher machine factory, we have to analyze the specific problems to see whether the requirements are reasonable, in general, it is not recommended that customers make additional modifications.
