目前,在我国一般小型建筑工地,JZC350砼搅拌机已成为小型移动式搅拌砼的主要机种之一。双锥型搅拌筒的搅拌特点是物料轴向前后串动和自落搅拌强烈。所以,它所搅拌的砼质量较自落式鼓筒型机为好,但同时双锥型搅拌筒的内壁磨损也较利害。如何针对磨损情况作一些必要的改进以延长搅拌筒的使用寿命是一个值得研究的课题。本文从双锥型搅拌筒内砼物料的运动状况着手,对 JZC350搅拌筒的磨损情况进行一些 At present, in China’s general small-scale construction sites, the JZC350 mixer has become one of the main types of small mobile mixers. The mixing characteristics of the double-cone type mixing drum is that the material is strongly stirred in the axial direction and in the front and rear. Therefore, the quality of the crucibles it stirs is better than that of the self-dropping drum machine, but at the same time, the inner wall of the double-cone mixing drum is also more susceptible to wear. How to make some necessary improvements to the wear condition to extend the service life of the mixing drum is a subject worthy of study. This article starts with the movement of the material in the double-taper type mixing drum and performs some wear on the JZC350 mixing drum.
