Dredging machine series: It is the battlefield, river dredging professional machinery (can also be used for river improvement), and its reliable performance, easy maintenance, long service life, minimal cost, heavy workload (500-1000 cubic meters per day) many advantages such as, digging through the sand filter after the separation of sandy pure, without impurities, is ideal for construction operations of precast concrete with sand. Rail-Shatti check equipment: with the sand mining machinery is iron extracted from the river the ideal equipment, can also get sand, iron sand two products, the next dug a depth of 3-20 m Pumping Barge Series: loading capacity of 10-40 cubic meters of sediment depth of 2-18 m pumping. Production of 20-60 cubic meters per hour, with 1110, 295, or 495-type diesel engine. Sand sieve Series: battlefield sieve sand professional mechanical, simple structure, the work load is heavy, durable, producing low-cost, easy maintenance and many other advantages, re-processing of sand, sand, gravel, automatic separation of impurities is the construction of precast concrete manufacturers ideal sand.
