For fine sand recovery machines, the screen is one of the most commonly used components and an important part of the fine sand recovery operation. So what are the main functions of the screen during the operation of the fine sand recovery machine? Before that, the editor will first lead you to understand the main working principle of the fine sand recovery machine.

  Working principle of fine sand recovery machine

The sand pump delivers the sand-water mixture to the centrifugal separator. The fine sand after centrifugal classification and concentration is supplied to the linear dewatering screen through the sand settling nozzle. After dewatering through the linear dewatering screen, fine sand and water are effectively separated, and a small amount of fine sand, mud, etc. are returned to the material. The water tank is then returned to the clean water tank. When the liquid level in the cleaning tank is too high, it will be discharged through the discharge port.

   In this process, after the centrifugal separator performs solid-liquid separation, the remaining sand will enter the dewatering screen through the nozzle. The main function of the dehydration screen is to further dehydrate the separated sand, so the role of the screen at this time directly affects whether the moisture content of the sand can achieve the desired effect. It can be said that the main function of the screen is to effectively separate sand and water, ensure that the moisture content of the sand is reduced to a very low level, improve the quality of the sand, and enable water to be reused, thereby achieving the purpose of energy conservation and environmental protection.

   When purchasing a fine sand recovery machine, be sure to pay attention to the raw materials of the screen.

   Therefore, when we purchase a sand and gravel recycling machine, we must pay attention to the raw materials of the screen. It’s just that the raw materials of the screen are better and the wear resistance is higher. In a long-term and complex production environment, it can ensure the high efficiency of the equipment, thereby saving maintenance and replacement costs for users and ensuring the quality of sand recovery. At the same time, in the process of recycling sand, we must pay attention to the correct use and maintenance of the screen, and perform regular maintenance and replacement to ensure the high efficiency of the equipment.

   The screen used in the environmentally friendly fine sand recovery machine is made of polymer polyurethane material, which has self-cleaning properties, does not block holes, has high screening efficiency and long service life. Because the polyurethane elastic screen uses steel wire rope as the skeleton material, and the polymer polyurethane has high elastic modulus, high strength to absorb impact force, and high wear resistance, it has high tensile strength, and its load-bearing capacity is even higher than that of rubber mesh. 2.5 times. Its service life is 8-10 times longer than ordinary metal screens, 3 times that of stainless steel screens, and 3.9 times that of natural rubber. It is currently the most wear-resistant screen material.
