Description

Shovel blade for Raymond mill

Technical Field

The utility model relates to the technical field of shovel blades, in particular to a shovel blade for a Raymond mill.

Background

The Raymond mill is a pulverizing mill, is produced in China at present, and is suitable for various mineral powder preparation and coal powder preparation, such as fine powder processing of raw ore, gypsum ore, coal and other materials. The method is widely suitable for high-fine powder preparation processing of various materials in industries such as non-flammable and explosive mineral products, chemical industry, construction and the like with Mohs hardness not more than 7 and humidity below 6%. The main machine of the Raymond mill mainly comprises a plum blossom frame, a shovel blade, a grinding roller arranged on the plum blossom frame and a fixed grinding ring. The working process of the Raymond mill is that the plum blossom frame drives the grinding roller and the shovel blade to rotate around the main shaft, and the grinding roller swings outwards and is tightly pressed on the grinding ring due to the centrifugal effect during rotation, so that the grinding roller rotates around the main shaft and also rotates around the axis of the grinding roller, the shovel blade is positioned in front of the lower end of the grinding roller and is fixed on the plum blossom frame at a certain angle, and materials in a main machine room of the Raymond mill are shoveled up and fed into a gap between the grinding roller and the grinding ring in the rotating process of the shovel blade and the grinding roller around the main shaft to form a material layer with a certain thickness, so that the grinding purpose is achieved due to the rolling of the grinding roller.

The scraper knife has important influences on grinding efficiency, yield, power consumption and the like, the current scraper knife is generally composed of a layer of bottom plate, an inner side plate and an outer side plate, materials are lifted up through the bottom plate and thrown away, the materials move upwards and outwards along the bottom plate due to the action of rotating centrifugal force in the material throwing process, the materials are close to the outer side plate to form a too concentrated material flow, the material flow mostly impacts the grinding middle part of the grinding roller and the grinding ring, the grinding roller and the grinding ring are ground through the grinding roller and the grinding ring, the material layer is unevenly distributed, the grinding roller and the grinding ring are abnormally worn, and the grinding roller is in a waist drum shape, so that the service life of the grinding roller is influenced, and the grinding efficiency is influenced.
