Improving gravel and crushed aggregates washing technology efficiency through application of high pressure washer

摘要

Removal of fine clay impurities is the most common method of mineral aggregates processing. Various washing devices operate with different effectiveness and capacities. The paper concerns the investigations of aggregate washing operations by using high-pressure washers. A comparative analysis of two types of washers, that is log washer and high pressure washer, shows that the second device operates at much higher effectiveness measured through the percentage of removal of clay impurities. The energy consumption is also more favorable for the high pressure washer.
