Introduction of the types of screens for placer gold washing equipment

There are many kinds of gold placer gold panning equipment screens on the market, so what kind of screen should be chosen, and what material is more durable? Let GoldMaster introduce the durability and characteristics of various screens. The common screens of cylinder sieves are as follows:

   The first one is ordinary metal screen: the durability of ordinary iron screen is poor, and the diameter of the screen hole can be customized. It is recommended that you generally not choose this screen when ordering.

   The second type is the iron plate punching type: the iron plate punching type mentioned here is used for the cylindrical sieve, and the punching is laser punching. The diameter of the sieve hole can be customized, and the sieve hole can be customized as a bell mouth. The horn hole is not easy to be blocked, and the top and bottom of the screen hole are in the shape of a horn. The top is small and the bottom is big, so that there will be no problem of small stones and the like getting stuck on the screen. This kind of screen is mostly used in small gold panning equipment, and is suitable for single-layer sieves, such as small gold panning vehicles.

   The third type is polyurethane rod screen: polyurethane rod screen is mostly used on the cylinder screen of large-scale gold panning equipment, and the screen has two or more layers. Polyurethane bar screen has high screening efficiency. The screen surface has self-cleaning performance, no hole blocking, and high screening efficiency. This kind of screen is lighter in weight than metal screen, which can reduce production energy consumption, so it can meet the requirements of large-scale development of screen machines. This kind of sieve is not popular in the market, so the gold panning equipment matched with this kind of sieve is relatively rare. Due to the strong water permeability of polyurethane, the large screen hole cone angle, its elasticity and its good relaxation performance, it can effectively avoid hole blocking under dynamic conditions. Polyurethane rod screen is suitable for screening and grading of wet fine-grained materials, so it can effectively prevent the adhesion of wet fine-grained materials.

   The fourth is the welded screen: the welded screen is made of manganese steel, because it is welded, and the mesh size is larger. It is made of manganese steel wire through precision butt welding, which is not out of shape, wear-resistant, non-slip and corrosion-resistant. It can be used for cylinder screen and vibrating screen.

   The fifth type is high-manganese steel screen: this screen uses high-quality high-carbon steel, manganese steel, and high-speed wire as raw materials. It is characterized by wear resistance, high temperature resistance, high toughness, shock resistance, tensile resistance, and high screening rate. This kind of cylindrical sieve and screen mesh is more durable, and the screen holes can be customized. The screen is a high-strength special screen containing manganese. It is stronger and more durable than ordinary screens.

In order to save the loss and maintenance time of the machine, GoldMaster has made reasonable improvements to the screen of the sand screening machine. By cutting the entire screen into pieces for installation, it is not only faster in installation time but also easy to replace. It is also very convenient. For some places with serious wear and tear, you can strengthen the strength of the screen and replace it with a better screen. This not only saves the time for replacement, but also greatly reduces the loss of the screen. The usual maintenance work should also be in place, observe the wear of the screen after get off work, replace and repair the screen that is about to be broken, and prevent the material from falling into the finished product due to serious damage after starting up again. pile up.
