NJ-160 type cement paste mixer

NJ-160 cement paste mixer will be standards for cement and water are mixed and stirred into a homogeneous paste test for determination of cement normal consistency, setting time and production stability test blocks available. Cement paste mixer is related to universities and research institutes laboratories cement production plant, construction units, quality supervision and other essential equipment [Description] NJ-160 type cement paste mixer technical parameters 1, stirring Yeh Kung turn slow : 62 ± 5r / min 2, stirring Yeh Kung turn fast: 125 ± 10r / min 3, stirring blade rotation Slow: 140 ± 5r / min 4, stirring blade rotation block speed: 258 ± 10r / min 5, motor power: Fast : 370 W, Slow: 170W 6, cement paste mixer stirring blade width: 111mm 7, stirring blade and vane shaft connecting thread M16 × 1 8, pot wall thickness: 1mm 9, the gap between the leaf and the pot: 2mm 10, stirring the pot capacity: 2.5L 11, power supply, power: 380V 50HZ 370W 12, Dimensions: 472 × 280 × 466mm 13, cement slurry mixer Weight: ≈45kg NJ-160 type cement paste mixer Practice 1, with cement paste mixers stirring, stirring the pot and stirred the leaves with a damp cloth first. 2, the mixing water into the mixing pot, then carefully weighed 500g cement is added in at 5s ~ 10s, preventing water and cement spill. 3, stirring the pot on the first seat pan mixer, stirring raised position, switch the blender on slow speed for 120s, stop mix 15s, the leaves and the pot wall of slurry scraping the pot in the middle, followed by high-speed stirring 120s stop. 4. After mixing, mixing well immediately insert the cement paste is placed on the glass substrate tryout, and with a knife inserted pound, shaking gently several times to scrape off excess paste, smooth out quickly The tryout and bottom over the Vicat, the center of the sample set in the pole test, reducing test bar until the cement paste surface contact, tighten the screws 1s ~ 2s, suddenly relaxed, so test bar sink cement paste the sink or in the trial arm stop release test bar test bar from the 30s when recording from the floor, lift the test bar, immediately wipe. The entire operation should be completed within 1.5min After stirring to test bar sink and paste from the bottom 6mm ± 1 when a standard cement paste consistency of paste, its mixing water for cement standard consistency water (ρ), by cement mass%.
