Foundation framework of roll mill

Abstract

The invention relates to a foundation framework of a roll mill. The foundation framework is used for connecting the roll mill and a civil engineering foundation; the roll mill comprises a millstone and a milling roll; the foundation framework comprises a reducer foundation underframe, at least two upright foundation underframes and a motor foundation underframe; the upright foundation underframes are uniformly arranged around the reducer foundation underframe; and the motor foundation underframe is arranged between any two adjacent upright foundation underframes. Compared with the prior art, the foundation framework of the roll mill has the advantages of simple structure, easiness in manufacturing, low production cost, convenience in installation and the like.

Description

technical field [0001] The invention relates to a basic frame, in particular to a basic frame of a roller mill. Background technique [0002] The remarkable features of high efficiency and energy saving of roller mills have gradually been recognized and promoted by the majority of users. At present, they have been widely used in grinding system operations in metallurgy, mining, energy, building materials and other industries, especially in the building materials industry. The mill has become the dominant system for cement raw meal, clinker and raw coal grinding. [0003] The structure of the roller mill adopts a vertical layout, that is, the overall center line of the equipment and the ground foundation are in a vertical state, and the appearance is a tower structure. The entire equipment is vertically located on the ground foundation. The role of the ground foundation, the static load and dynamic load of the mill are transmitted to the ground foundation through the foundat...

AI Technical Summary

Problems solved by technology

There are many roller mills with different specifications and structures in the world today, and the basic frame structures included in them are different. The relevant documents also disclose the structure and characteristics of the basic frames equipped with various roller mills, but this type Due to the unreasonable structural design of the frame or its limitations, especially after the mill is enlarged, the foundation of the equipment will vibrate too much during the operation of the mill, causing abnormal subsidence and cracking of the foundation and chain damage to peripheral equipment. , affecting the normal operation of the entire production line. Secondly, due to the design of the foundation frame structure, its processing and production are too difficult and costly, and the construction difficulty and cost of the corresponding civil engineering foundation are also too high.

These factors have seriously restricted the development trend of large-scale mills and brought about an increase in the investment cost of the entire production line.
