011.25.520 Single row ball slewing-bearing with external gear -for Cement mixer

With the emphasis on environmental protection, the traditional casting technology has gradually developed into an advanced and enviroExternal-gear-Single-row-ball-slewing-bearing-for-sand-mixernmentally friendly casting technology. The process technology of large castings is also inseparable from advanced process equipment. Under the premise of the continuous improvement of automatic control technology, the casting process of self-hardening sand molding requires higher and higher precision of sand mixing. Sand mixing machine is to make the components of the sand evenly mixed, and make the binder effectively coated on the surface of the sand. Sand mixing machine is the main equipment of casting sand processing molding sand mixing and is also the key equipment to obtain qualified molding sand. The sand mixer uses the relative movement of the roller and the roller plate to crush the material between them by rolling and grinding. The sand mixer also mixes the material while crushing the material. It is an ideal equipment for producing free brick, lime sand brick, cement brick, firebrick, pulverized and mixed fly ash, boiler slag, tailing slag and industrial waste slag as raw materials for brick making.

Slewing ring can bear axial, radial load and tilting moment load simultaneously. It can be combined with pinion, planetary gearbox and motors…
