Description
Technical Field
The invention relates to the technical field of vertical mills, in particular to a durable built-in bearing type grinding roller single-double-support vertical mill capable of preventing oil leakage.
Background
The vertical mill is a grinding device integrating fine crushing, drying, grinding, powder selecting and conveying, and is widely used for grinding various solid materials and superfine grinding in industries of cement, building materials, electric power, metallurgy, chemical industry, nonmetallic ores and the like. The grinding process of the vertical mill is completed by a set of grinding devices (namely a grinding roller and a grinding disc), and materials are ground into powder between the grinding roller and the grinding disc. The grinding device is rotated by the grinding disc and correspondingly drives the grinding roller to drive, and the grinding pressure is mainly used for pressurizing the grinding disc materials by a set of hydraulic device except the dead weight of the grinding roller. The milled material contains a large amount of coarse powder, the powder is selected by a matched powder selecting machine, the powder selecting process is that the powder is selected by air flow, most of the coarse powder automatically falls on a millstone in the air flow process, the coarse powder is received and ground again, and the rest of the coarse powder is selected by the powder selecting machine to be a finished product, and the finished product is sent to a finished product storage through a dust collection and conveying system. The residence time of the material on the grinding disc is mainly determined by three factors: firstly, the grinding disc speed affecting the centrifugal force; secondly, the friction between the material and the millstone and the internal friction of the material; thirdly, the structural form and the cooperation of the grinding disc and the grinding roller determine the motion stroke mode. The third factor is the key to determine the design thought of each vertical mill manufacturer, and the different mill roll and mill form determine the mill speed and material residence time on the mill of each manufacturer. When selecting the vertical mill, the user must select a proper vertical mill according to the characteristics of the ground materials.
Working principle: the motor drives the millstone to rotate through the vertical speed reducer, the solid raw material enters the center of the millstone from the feed inlet through the air locking feeding device, is thrown to the periphery of the millstone under the action of the centrifugal force field and is repeatedly crushed by the grinding roller to be crushed. The crushed materials overflow from the edge of the millstone, the powdery materials are carried up by high-speed air flow rising from the lower part of the machine, when the rising air flow and the powdery materials pass through the powder selecting machine at the upper part of the mill, under the action of a rotor rotating rapidly, coarse powder is separated out and falls into the center of the millstone to be ground again, fine powder is discharged from the upper part of the mill along with the air flow, and the fine powder is collected in a dust collecting device to obtain the product. The granular materials which are not taken away by the air flow are returned to the feeding port of the mill through the bucket elevator of the external circulation after overflowing the millstone, and enter the mill together with the newly fed raw materials for re-grinding. For materials with higher moisture content, hot air is introduced into the mill, and wet materials are fully contacted with hot air flow in the grinding, powder selecting and flowing processes to be dried, so that the moisture requirement of the product is met.
