High-strength powder chemical industry grading screen
The vibrating screen divides the broken materials with different particle sizes through a single or multi-layer sieve surface with uniformly distributed holes for many times, and divides them into several different levels to become sieving. The particles larger than the sieve opening remain on the screen surface and are called the oversieve of the sieve surface. The particles smaller than the sieve opening pass through the sieve opening and are called the undersieve of the sieve surface. The actual screening process is: after a large number of broken materials with different particle sizes and mixed thicknesses enter the screen surface, only a part of the particles are in contact with the screen surface. Due to the vibration of the screen box, the material layer on the screen is loosened, so that large particles exist. The gap is further enlarged, and small particles take the opportunity to pass through the gap and transfer to the lower layer or transporter. Because the gap between small particles is small and large particles cannot pass through, the original chaotically arranged particles are separated, that is, they are stratified according to particle size, forming an arrangement rule with small particles on the bottom and coarse particles on the top. For the fine particles that reach the screen surface, those smaller than the sieve hole can pass through the screen, and finally realize the separation of coarse and fine particles and complete the screening process.
The characteristics of high-strength powder chemical industry classification screen:
1. Low energy consumption, low noise
2. High screening accuracy, large capacity and simple structure.
3. Fully enclosed structure, good sealing, prevent dust from overflowing, automatic discharge
4. The main parts of the rotary vibrating screen are welded together with copper plates and cross-sections (the parts are connected by bolts). The overall rigidity is good, solid and reliable.
5. Unique screen structure design (single screen, double hoops, mother-in-one type), convenient and quick to change the screen (only 3 to 5 minutes); can extend the service life of the screen, thereby reducing the cost of screen consumables; in addition, this This design can use various screens (nylon, stainless steel woven mesh, PP material).
6. The machine is exquisitely designed and easy to assemble; one person can operate the machine.
