Cylinder and trough-type washing machine is ferrous and nonferrous metallurgy, mining, iron and steel, metallurgy, chemicals, building materials used to wash ore, stone and large-scale mining equipment, the larger is its capability to meet the high productivity cleaning ore, stone ideal equipment requirements of enterprises. Spiral washing machine, spiral stone washing machine by means of a different proportion of solid particles and thus different sedimentation velocity in the liquid principle, mechanical grading equipment washing. FG series washing machine used in metallurgy, building materials, utilities and other industries washing, grading, cleaning and other operations, spiral washing machine for washing job size and coarse-grained materials. Spiral washing machine by means of a different proportion of solid particles and thus different sedimentation velocity in the liquid principle, mechanical grading equipment washing. Spiral washing machine is to use the buoyancy of the water, the separation of dust and impurities in the sand. After the flights of agitation, to water treatment to remove impurities, improve transportation purposes. And in the promotion process, we have also been mixing work. Stir sand is reached, no fine, coarse sand of the points. Spiral washing machine having a spiral body length, sealing system, simple structure, strong processing capability, and easy maintenance. Sand water content, low clay content. Widely used in a variety of ore mining industries. Commonly used washing equipment includes: 1. Water Wash griddle. Washing method for washable ore use water cannons on a fixed bar screen flush. 2. barrel washing machine. It includes a cylindrical sieve and a cylindrical scrubbing machines. High speed cylindrical sieve, sieve cylinder wall safe longitudinal Yang plate, annular baffle and high pressure water jet equipment in order to improve the ability of granular, for washable ore. 3. cylinder scrubbing machines. Front and rear cylinder into two sections, the front section without holes for soaking and granular ore, the rear section has holes for debris separation. 4. trough washing machine. Commonly used in hard to wash ore, with a strong scrubbing action. The ore pre-soaked, disposed in the high pressure water jet washing process, the vibration is applied, adding a small amount of agent (e.g. 1% concentration of NaOH), etc., can improve the washing efficiency. Washing efficiency have a greater impact on the dressing. Henan Chen billion environmental Engineering Technology Co., Ltd.
