May 25 2020 The bucket wheel sand washer is developed using advanced technology at home and abroad combined with the actual situation of the sand and stone industry It has three functions of cleaning dehydration and classification The sand washing effect is powerful It is widely used in finegrained industries such as metallurgy building materials hydropower etc Washing grading and

Classification of Aggregates Based on Size Aggregates are available in nature in different sizes The size of aggregate used may be related to the mix proportions type of work etc the size distribution of aggregates is called grading of aggregates Following are the classification of aggregates based on size Aggregates are classified into 2 types according to size

The production of these specialist silica sands for application in glass manufacturing requires specialist screening and classification equipment from CDE This complex process will first involve a detailed analysis of your feed material both in terms of the particle size distribution PSD and the chemical properties of your silica sand
