Ensure The Stability Of Grinding Mill Rolling Distance

Ensure The Stability Of Grinding Mill Rolling Distance

Summary of contents: This paper believes that the stability of the mill rolling distance can be guaranteed from three aspects, namely structural design, material selection and processing precision. The material refers to all the parts and materials related to the rolling distance on the mill. The strength and rigidity must ensure the rigidity, which is the deformation amount under the force condition of the parts, because it is an important guarantee for the stable grinding effect, the deformation amount must be small, otherwise it is difficult to ensure a good grinding effect.

This paper believes that the stability of the mill's rolling distance can be guaranteed from three aspects, namely structural design, material selection and machining accuracy.

1. Structural design is the foundation.

The design of the mill rolling structure is the basis. This paper believes that it is necessary for the technicians who design the mill to carefully study the relevant documents of the manufacturers of the excellent mills, and then let the mill first make the domestic mill from the structural design. The machine reached the relevant level.

2. Material selection is guaranteed.

The material refers to all the parts and materials related to the rolling distance on the mill. The strength and rigidity must ensure the rigidity, which is the deformation amount under the force condition of the parts, because it is an important guarantee for the stable grinding effect, and the deformation amount must be Small, otherwise it is difficult to guarantee a good grinding effect. The materials of this part are basically divided into three categories. One type of material is casting, that is, gray cast iron parts; the second type of material is cast steel, which is basically ZG270~500; the third type of material is rod type parts, this part is In terms of weight, the mill has a small proportion, but it is very important for the mill. Therefore, from the material selection, we are pursuing higher quality, so the cost of the whole machine can not increase much. But it is crucial for the quality of the whole machine.

In terms of geometric size, as long as the space position allows, choose as large as possible, and the safety factor is larger. This design concept needs to be paid attention to, especially for the design of the mill. Also pay attention to the choice of alloy materials. In the rotating part, the shaft and the sleeve parts are reasonably designed in the parts with high precision requirements, which is beneficial to reduce the manufacturing cost and ensure the manufacturing precision, and prolong the service life of the related parts, and it is more convenient to replace the parts.

3, processing accuracy is the key.

The initial use of our mechanical equipment is not much different from that of foreign equipment. However, after using it for a period of time, it has become more and more difficult to use, the precision is not up to high, and the failure rate is high. This is largely due to these mechanical parts. The shoddy, the attention to detail is not enough, the precision is not up to the requirement, and a grinding-in problem arises, so it is necessary to strictly control and control the surface finish requirements between the contact parts. At present, the processing methods are basically no problem in terms of technology and equipment. The processing equipment and processing methods of various types of grinding machines are guaranteed, so the shape and geometric size of the grinding machine can basically meet the requirements and are easy to control, but the operation level of the worker technician is still Need to be improved, which directly affects the manufacturing precision of the mill, so the surface finish of the parts needs further assurance.
