Working Principle of Air Flow Sieving Machine

Air flow sieving machine to abandon the traditional principle of gravity operation, in a closed state using high-speed air flow as a carrier, so that the full diffusion of powder particles with enough kinetic energy to the sieve mesh, to achieve the purpose of rapid classification. As the shape of the horizontal so it is also called horizontal vibro screen machine.
The mesh shape is cylindrical, placed in the body, the material through the screw conveyor system, and air mixing, atomization into the cylinder. Through the cylinder within the wind wheel blades so that the material at the same time by the centrifugal force and cyclonic propulsion, which nearly the material jet through the network, discharged from the fine material discharge, can not be over the net material along the cylinder wall from the coarse material discharge port.The airflow screen has the advantages of large output, high efficiency, non-stick network, not blocking the mesh and fine fineness.

What Are the Components of Air Flow Sieving Machine

The components of air flow sieving machine include a base frame, a motor, a crank, a connecting rod, a variety of sieve nets with varying mesh sizes, and supporting meshes. The machine also has a sieve, which is the more technical part of the machine and is commonly made of stainless steel woven wire mesh. The sieve is held in place by a screen frame, which is a circular metal ring. The machine also has a skirt, which allows the sieves to stack without tipping over.

The working principle of the sieving machine involves a vertical vibration motor as the vibration source. The motor drives the upper vibrating plate to vibrate, transmitting the vibration to the screen frame. The material particles smaller than the aperture of the screen are sieved to the lower screen frame, separating materials of different particle sizes and determining the particle size composition of the material. This allows for effective filtering, grading, and screening of materials.

Sieving machines are important devices used in various industries and trades. They are used to perform accurate analysis of raw materials, additives, and supplies to achieve proper results and produce perfect products. These machines can analyze various materials, such as sands, soils, construction materials, food, and chemical products. The sieving machines need to cover various ranges of mesh sizes to accommodate different materials. They can support both dry sieving and wet sieving processes.

In sieving machines, the material is separated through a wire-mesh, with smaller particles passing through different mesh widths than larger particles. Analyzing sieves with different sizes and mesh ranges are used to provide optimized solutions for sieving different materials. It is important to clean the sieves properly to avoid contamination and ensure accurate results. Some sieving machines perform three-dimensional sieving movements to save time and improve repeatability of results.
