Combined machine base applied to large Raymond mill

Abstract

The invention discloses a combined machine base applied to a large Raymond mill. The combined machine base applied to the large Raymond mill comprises a machine base body fixed to a concrete foundation and a mill ring arranged in the machine base body. A mill air inlet passage is arranged outside the machine base body, the longitudinal section of the concrete foundation is approximately of a U shape, the lateral wall of the concrete foundation is of a step structure, and the main machine base body with the mill ring inside is fixedly arranged on the bottom wall of the concrete foundation. The inner edges of reinforcing plates with the outer edges fixed to the step surface of the lateral wall of the concrete foundation are fixedly connected with the lateral wall of the main machine base body. A traditional integrated machine base for the Raymond mill is divided into the main machine base body and the reinforcing plates fixedly connected with the side of the main machine base body, so that the problems of over-width and overweight of the Raymond mill during production and conveying are resolved. The concrete foundation fixedly provided with the machine base is prefabricated into a foundation with the air passage. When the specification of the Raymond mill is increased, the problems that a volute is too large in size and can not be conveyed easily are resolved. Besides, the main machine base body, the reinforcing plates and the concrete foundation are firmly connected into a whole through foundation bolts fixed in grouting holes, and the rigidity of the machine base of the Raymond mill is increased.

Description

technical field [0001] The invention relates to a Raymond mill, in particular to a combined base for a large Raymond mill. Background technique [0002] When Raymond mill is used as a small mill (the inner diameter of the grinding ring is up to 2.3 meters), compared with the vertical mill of the same type, it has an irreplaceable advantage in terms of output and energy consumption per unit of product, and it is still used in the world today. widely used everywhere. [0003] The existing Raymond mill is mainly composed of fan, main machine, powder classifier, powder collector, pipeline and other components. Although the system is similar to the vertical mill, the overall development is obviously behind the vertical mill, especially the large-scale Raymond mill, which lags behind the vertical mill in terms of stand-alone output, grinding function, system control, and maintenance. The most prominent one is the low output of a single machine. The output of Raymond Mill in prod...

AI Technical Summary

Problems solved by technology

With the increase of the type of Raymond mill, the total thickness L of the grinding ring and the machine base increases sharply, resulting in the over-width and overweight of the overall machine base in the casting, processing, transportation and other links, and the increase of the total thickness also hinders the The structural design of the volute, that is, when the size increases sharply, it will lead to a super-volume volute (such as Figure 5 Shown) Difficult to transport

Therefore, the structure of the existing machine base has formed a short board that limits the development of large-scale Raymond mills
