砌块和其它混凝土制品的原材料配合比准确与否,直接关系到能否满足制品成型的工艺要求和制品质量。而配合比又主要取决于混凝土混合搅拌之前的配料称量。由于配料称量的误差往往较大和骨料的匀质性较差,配料过程中靠固定用水量或目测给水的方法,是难以保证制品成型所要求的混合料和易性和稠度的。为此,我们研制了混凝土搅拌机自动加水装置,经3个多月的生产使用,取得了较好的效果,并于不久前通过了鉴定。一、水分控制仪的工作原理近几年来,部分砌块生产厂家从国外引进的砌块生产线,都带有自动加水装置的强制式搅拌机,其工作原 The accuracy of the mix ratio of raw materials for blocks and other concrete products is directly related to whether it can meet the process requirements and product quality of product molding. The mix ratio depends on the weight of the ingredients before the concrete is mixed and stirred. Because the errors in the weighing of the ingredients are often large and the homogeneity of the aggregates is poor, the method of fixing the amount of water or visually measuring the water supply during the batching process is difficult to ensure the required mixability and consistency of the products. To this end, we have developed a concrete mixer automatic water device, after more than three months of production use, achieved good results, and passed the appraisal not long ago. First, the working principle of the moisture control instrument In recent years, some block manufacturers imported from abroad, the block production line, all with automatic water device forced mixer, its original work
