A double-width plate iron water mill

Abstract

The invention discloses a double-plate type iron water-powered roller. The double-plate type iron water-powered roller comprises a runner wheel framework assembly and an edge-runner pan and is characterized in that the runner wheel framework assembly comprises a hub, double plates and a rim, which are welded to form one body, wherein a hollow structure is formed between the two plates, connecting rods are circumferentially welded and distributed on the plates, a block combined wheel flange lining plate is arranged at the outer side of the rim in a fastening manner by a bolt and a nut, a spring is arranged on the bolt at the inner side of the rim in a sheathed manner and is arranged between the rim and the nut, and the edge-runner pan and the runner wheel framework assembly are made of an iron material. The double-plate type iron water-powered roller has high production efficiency, low power consumption, a low equipment fault rate and little part abrasion.

Description

technical field [0001] The invention relates to a water mill, in particular to a double-width iron water mill. Background technique [0002] At present, in the domestic quartz sand wet crushing process, there are mainly two kinds of rod mill crushing process and water milling process. Rod mill wet crushing processing technology requires large equipment investment and high production and operation costs (mainly because the mechanical efficiency of the rod mill is relatively low in general machinery). It is completed by impact and grinding. This processing method makes the consumption of steel rods larger. [0003] In the water milling process, the grinding wheels and discs are made of stone materials, and the water mills using stone materials are mainly considered from the simplicity of the iron removal process for product processing. However, with the development of quartz sand product processing technology, the development of iron removal machinery and the perfection of s...

Problems solved by technology

[0006] 3. The wear and consumption of the grinding wheel material is accompanied by the reduction in size and weight, which affects the effect of product crushing and processing. The productivity decreases with the reduction in the size and weight of the grinding wheel, and it will also affect the Changes in product particle size distribution range and uniformity of particle size

[0007] 4. For water mills made of stone materials, the wear rate of the rollers is high, the replacement is frequent, and the labor intensity of the workers is high; usually a stone roller weighs more than 2T, and it often takes up to 2 to 4 hours to replace a roller Occupies a long production auxiliary time, which will also greatly affect the effective working time of the water mill

[0008] 5. In order to meet the convenience requirements of frequent replacement of rollers during production, the manufacturing and assembly accuracy of the machinery is relatively low. The drive shaft and bearing basically have no matching accuracy requirements, and there is a large size gap between them, so the vulnerable parts in production Due to the low service life of the additional mechanical dynamic load, the frequent failure rate of the equipment is high, especially the mechanical failure rate caused by the transmission bearing mounted on the roller and the drive shaft that drives the roller to rotate. This is also the case. The main factors restricting the production application and further development of stone water mill
