QS-type air screening machine is a fine powder with a network of high-precision screening and screening equipment, widely used in chemical, food, paper, metallurgy, building materials, rubber, talcum powder, zinc powder, starch, coal fly ash, Sieve flour and other powdered herbs using graded, continuous screening for the fineness in the range of 80-500 mesh powder material good, the screen can be arbitrarily replaced. Use features: The product high screening frequency, large output, fineness accurate, no oversized mixed-level phenomenon, screen stand pretend not load. Long service life. Use a wide range of fineness. Fully enclosed structure no dust. Noise and low energy consumption, continuous operation and easy maintenance. Technical parameters: Model QS-600 QS-1000 QS-1500 QS-1800 air flow (m3 / h) 400 1000 1600 2200 mesh size (mesh / inch) 80-500 feed size (mesh) screen machine power 40-60 (KW) 3 7.5 11 15 spindle speed (rpm) 960 960 680 500 screening machine outside diameter (mm) diameter 600,100,015,001,800 full height (mm) 1200 1600 2200 2900 Effective screen surface (m2) 1.2 2.0 2.8 3.6 Third, the principle air screen with flexible feed dispersion process using a high speed air flow as a carrier, high-speed air in the sealed state was boiling atomizing the powder was shaped floating up in the settlement of a negative pressure state through a sieve particles meet the requirements of the production process net to complete the screening process grading powder materials. Fourth, work characteristics: 1, easy screen installation and removal fast and 2, the device easy to install the machine without basic equipment can move freely according to production needs, adjust the position of the main and auxiliary machinery. 3, no environmental pollution
