The vibrating screen is a screening equipment widely used in industries such as coal, electricity, metallurgy, building materials, and chemical engineering. The vibrating screen uses a vibrating motor as the vibration source, causing the material to be thrown up on the screen and move forward in a straight line. The material evenly enters the feeding port of the screening machine through the feeder, and various specifications of screens are produced through multi-layer screens. The feeding and unloading are discharged from their respective outlets. Linear vibrating screen (linear screen) has the advantages of stability and reliability, low consumption, low noise, long service life, stable vibration mode, and high screening efficiency. It is a new type of high-efficiency screening equipment widely used in industries such as mining, coal, smelting, and building materials Refractory materials, light industry, chemical industry, and other industries. The elliptical sieve has the advantages of high efficiency, high screening accuracy, and wide applicability. Suitable for solvent and cold sintered ore screening in the metallurgical industry, ore grading in the mining industry, and grading, dehydration, and demetrification in the coal industry.
