The foundry sand vibrating screen is a kind of equipment specially used to process foundry sand, and its core function is to screen and grade the sand. Through the vibration of the vibrating screen, the sand particles produce continuous rolling and jumping on the screen surface, so as to achieve the purpose of screening. This kind of equipment is widely used in the foundry industry and helps to improve the quality and production efficiency of casting products.
The foundry sand vibrating screen is usually composed of a screen box, an exciter, a shock absorption system and a transmission device. The screen box is the main working part, which is composed of a plurality of screens of different specifications, and different screens can be replaced according to needs to achieve the screening of sand of different specifications. The shaker is the key component that makes the screen box vibrate, usually using an eccentric or electromagnetic shaker, which can produce strong vibration. The shock absorption system is to reduce the vibration and noise generated by the operation of the equipment, and ensure the stability and service life of the equipment. The transmission device transmits the power to the exciter, so that it drives the screen box to vibrate.
In the working process of the casting sand vibrating screen, the sand particles enter the screen box through the feed port, and under the action of vibration, the sand particles of different specifications produce different movement trajectories on the screen screen, so as to achieve screening. The screened sand particles are discharged through the discharge port, and the sand particles of different specifications enter different collectors respectively to realize the classification and separation of the sand.
The use of foundry sand vibrating screen not only improves the quality of casting products, but also greatly improves production efficiency. It has the advantages of simple structure, convenient operation and low maintenance cost, and is one of the indispensable important equipment in the foundry industry. In the future, with the continuous development of the foundry industry, the application prospect of foundry sand vibrating screen will be broader.
