Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand screening, in particular to a quartz sand screening device. Background Art

[0002] A quartz sand screening device is a crucial piece of equipment used to separate quartz sand into different particle sizes. Its operating principle is to utilize the vibration generated by a vibrating motor, which is transmitted through a screen box to the screen mesh, causing the mesh to vibrate periodically. This creates a dynamic particle flow on the screen surface, with smaller quartz sand particles passing through the mesh holes and into the underside, while larger particles remain on the screen surface, thus achieving material screening. High efficiency: Quartz sand can be quickly graded into several grades with varying particle size distributions, improving production efficiency. Its sophisticated and durable design allows for screening of any powder or mucus, while the mesh size is easily changed, simple to operate, and convenient to clean. High screening accuracy: Adjusting the mesh size allows for precise grading of quartz sand. Quartz sand screening devices are widely used for grading or sorting powders and small and medium-sized materials in industries such as metallurgical powders, chemicals, grain, pharmaceuticals, fertilizers, abrasives, ceramics, coal, refractories, and building materials. It is especially suitable for screening various dry powdery or granular materials with a particle size of 0.074-5mm, a water content of less than 7%, and no stickiness.
