Pressurized self-balancing ultra-large roller mill

Abstract

The invention discloses a pressurized self-balancing grinding machine with ultra-large rolls. The pressurized self-balancing grinding machine comprises a seat and a grinding ring arranged on the seat, wherein a grinding roll component is arranged in the grinding ring; the grinding roll component is driven to work through a central rotor arranged at the central position of the seat; the grinding roll component is composed of an inner grinding roll and an outer grinding roll in a sleeving manner; a rotary bearing is arranged between the combined surfaces of the inner grinding roll and the outer grinding roll; a shaft hole is horizontally formed in a central rotor located in a central hole of the inner grinding roll; the two ends of a rotary shaft arranged in the shaft hole in a penetrating manner extend to the sidewall of the inner grinding roll; and inner grinding roll thrust devices are arranged in blind holes which are symmetrically formed in central rotors located at an upper position and a lower position of the rotary shaft in a staggered manner respectively. The pressurized self-balancing grinding machine disclosed by the invention is ingenious and reasonable in structure, and gets rid of the design limit that the size of the grinding roll component of the grinding machine cannot be greater than 1 / 2 of the diameter of the grinding ring; the diameter of the grinding roll component theoretically can be close to the dimension of the inner diameter of the grinding ring; and compared with the traditional structure, the grinding roll component with an ultra-large structure is capable of achieving much engaging-in of materials, high in efficiency, and high in yield.

Description

technical field [0001] The invention relates to a ring roller mill or a Raymond mill, in particular to a pressurized self-balancing ultra-large roller mill. Background technique [0002] Currently commonly used mills include suspension roller mills (or called Raymond mills) and ring roller mills (or called three-ring mills). The main structure of the suspension roller mill is as follows: figure 1 As shown, it includes a machine base 1-1, a grinding ring 1-2 installed on the machine base 1-1, a rolling device with grinding rollers 1-3 arranged in the main machine, and a working shaft 1 located at the center of the main machine -4 Turn and drive the grinding roller 1-3 of the rolling device to press against the grinding ring, and roll the material between the grinding ring 1-2 and the grinding roller 1-3. From figure 1 It can be seen from the figure that the diameter of the grinding rollers 1-3 on the rolling device cannot exceed 1 / 2 of the diameter of the grinding ring due...

AI Technical Summary

Problems solved by technology

The ring roller mill of this traditional structure has a simple structure, the grinding roller is empty on the shaft, and there is no bearing component. Due to friction, impact, etc., the grinding roller on the upper surface will produce huge noise in actual production
