How to solve the problem of low efficiency of concrete mixer.

　　1.粘物法：如果滚筒、托辊的局部上粘有物料，将使该处的直径增大，导致该处的胶带拉力增加，从而产生跑偏。应及时清理粘附的物料。

　　If there is an increase in the diameter of the belt on the roller, it will increase the diameter of the roller. The adhered materials should be cleaned up in time.

　　2.混凝土的任务量及其工期的考虑：以此来选用多大规格的混凝土搅拌机，同时要考虑混凝土的瞬时和平均量。

　　2. The task quantity and construction period of concrete: how large the concrete mixer should be selected, and the instantaneous and average quantity of concrete should be considered at the same time.

　　3.除日常对商品混凝土搅拌机维护保养外，当混凝土搅拌机运行一个月(二班制)后，要以操作者为主，维修工人配合，在规定的保养时间内，按混凝土搅拌机机型规定的保养内容及要求．对混凝土搅拌机进行一次一级保养。一级保养主要范围是。

　　3.
