Gold Gravity Concentration Equipment
The STL water-jacketed Gold Concentrator is a kind of gravity separation equipment. It was developed by Changchun Gold Research Institute Co., Ltd. in 1985 and entered the market. At present, it has been used in many domestic and foreign companies. It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.
The main indicators of this series of equipment basically reach the level of similar international products (such as Nielsen gold selectors, etc.). Compared with similar equipment at home and abroad, this series of equipment has the advantages of high cost performance, easy operation, and low maintenance costs.

ZF thruster uses Ecoshield paint to extend life
It is reported that ZF Marine Krimpen applied Subsea Industries' Ecoshield reinforced coatings to its azimuth propeller nozzles and underwater parts for inland waterway operations.
The Dutch-based ZF Marine Krimpen is a division of the German ZF Group. Currently, ZF Marine Krimpen is using Ecoshield coatings on propellers for several US customers to reduce wear and tear in brown water such as the Mississippi River.
ZF Marine hopes to improve the protection of the underwater part of the propeller and to prevent damage caused by cavitation corrosion caused by intrinsic waterways, especially the common waste, sand and silt of the Mississippi River.
ZF Marine offers a choice of Ecoshield propellers as an option to demonstrate that the coating is a very good solution for extending the life of tugboats and pusher propellers operating in shallow water. The coating not only does not cause propeller damage, but also reduces maintenance and operating costs. These advantages are not only reflected in the tugboat, but also in the port tugs and passenger ships.
