Embodiment Construction

[0020] Below in conjunction with accompanying drawing, technical scheme of the present invention will be further described:

[0021] The swing arm type powerful mill of the present invention takes the ring roller mill as an example, and its milling host includes a host shell 1, a host upper cover 6, a host base 3, a main shaft 2, a grinding roller device and a grinding ring 12, and the host shell 1 The upper and lower openings of the main engine are respectively connected and installed with the main engine upper cover 6 and the main engine base 3 through flanges. The main engine main shaft 2 is vertically placed on the central axis of the main engine shell 1. The bearing positions 7 and 4 are respectively supported and installed, and the upper and lower bearing positions 7 and 4 are respectively arranged at the center of the upper cover 6 of the main machine and the base 3 of the main machine. The outer conical surface of the grinding ring 12 is fixedly installed after coopera...

Abstract

The invention discloses an oscillating arm type strong grinding mill. A grinding roller device and a grinding ring of a host grinding mill are arranged in a host grinding mill shell; the grinding roller device is installed on a host spindle; the grinding roller device comprises grinding roller racks, oscillating arms, grinding rollers, grinding roller shafts, grinding roller shaft pushing racks and thrust mechanisms; the inner ends of the oscillating arms are hinged in grinding roller rack ring slots; the outer ends of the oscillating arms extend out of the grinding roller racks; the grinding roller shafts are arranged on the ring slot holes of the oscillating arm extending ends; the upper ends and the lower ends of the grinding roller shafts are arranged in radial slots arranged on the top and the bottom of the ring slot in a sliding fit mode; the grinding roller shaft pushing racks for pushing the grinding roller shafts are arranged in oscillating arm ring slots in a sliding mode; the thrust mechanisms for generating radial thrust to the grinding roller shaft pushing racks are arranged on the bottoms of the oscillating arm ring slots; and the grinding rollers are arranged in the grinding roller shaft pushing racks and are installed on the grinding roller shafts by bearings. According to the oscillating arm type strong grinding mill disclosed by the invention, the thrust mechanisms are adopted to apply additional thrust on the grinding rollers in addition to centrifugal force, and grinding force on the material by the grinding rollers is increased so as to obtain better crushing effect and improve the yield.

Description

(1) Technical field: [0001] The invention relates to a powder processing equipment, in particular to a swing arm type powerful pulverizer. (2) Background technology: [0002] The pulverizer is a commonly used equipment for mineral powder crushing in my country, and it is widely used. [0003] Powder processing is divided into coarse powder, fine powder and ultrafine powder processing. For example, the processing of 60 mesh or 400 mesh coarse powder or fine powder can be processed by Raymond machine, but higher mesh powder should be collected ( 500 mesh to 3000 mesh or even higher), if the Raymond machine is still used for processing, the prominent problems such as processing time, efficiency, vibration and noise of the Raymond machine will be difficult to solve. Therefore, if you want to obtain finer or ultrafine powder, you need other structural types of mills, namely ring roller mills. [0004] Whether it is a Raymond machine or a ring roller mill, the crushing mechanism...
