Mobile Crushing Plant

In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material. Traditional single-layer shaker table covers large area and has low capacity. The launch of double-layer shaker table solves available problems in the use of single-layer shaker table. Double-layer shaker table has the features of small footprint, large capacity and
