One Overview

Sieve analysis of negative pressure meter Is a novel powder fineness Sieve Tester , It is satisfied GB1345-91The test method for fineness of cement new standard dry sieve method requires special instruments, used in cement production and cement fineness test control. The instrument has Screening High speed, high precision, revival and other advantages, is widely used in cement quality inspection stations, cement plants, research institutes and tertiary institutions for cement physical performance test lab ,Powder fineness test in other industries are also available.

Two Technical parameters

Third, the principle of FYS-150 cement fineness suction sieve analysis instrument Using air as screening of power media work Shi, whole system keep negative pressure state, screen network in of stay measuring fine powder material in rotating of Jet mouth spray out of air role Xia is flow state-like, and with air with movement, which grain diameter is less than screen network aperture of fine particles by air led through screen network was pumping go, and grain diameter is greater than screen network hole of rough particles is left in screen network in to reached screening of purpose. If screening system with a small cyclone dust collection canister, you can sieve fine particles from the gas stream by collecting, collection rate can reach above 90 ℅, so as to reduce the number of cleaning the vacuum cleaner.

Four, instructions for use

(1) Instruments placed on a level surface, opened the back door to check that all parts are properly installed.

(2) Weighing of cement materials 25gInto try and cover the screen within the screen cover, and then start the equipment, stop remove the specimen screening sieve residue objects into the balance range, sieve analysis results are obtained.

(3) Operators must adjust work pressure -4000~-6000Pa Range. Instruments in the 2min Automatic stop

(4) After each use, brush Test sieves Network on both sides gently brush clear, and put screen network on with light, check screen hole Hou put test screen save in dry container or plastic bags within Dang test screen jam Shi, can will its anti-reset in screen seat Shang, cover Shang screen cover anti-sucking, again with brush brush clear, if screen network jam serious, can first will test screen put in water in the soaking a time again scrub.

(5) If the cement powder in bottle full of the dust, dust collection bottle should be pulled down from the cyclone reload after the evacuation.

(6) The vacuum cleaner should pay attention to cleaning on a regular basis in order to keep the dust collection bag clean
