FT-106 ordinary abrasive bulk density tester Instructions
FT-106 ordinary abrasive bulk density tester is in accordance with international standards ISO9136: 1989 (Determination of bulk density of coarse grains) and industry standard JB / T7984.2-1999 (Ordinary coarse grit abrasive Determination of bulk density) of the relevant technical requirements development and production of special detection equipment, suitable for detecting manufacturing bonded abrasives and coated abrasives bulk density of coarse particles of abrasive materials, but also for the detection of other granular materials bulk density of its detection methods and results and international common The detection method has complete versatility.
1. Working Principle
The abrasive test load funnel, open the drain valve, abrasive natural port along the funnel and into the measuring cylinder fall, and will fall into the measuring cylinder abrasive Calibrating the balance Weigh Calibrating the measuring cylinder abrasive quality, and then divided by the volume measuring cylinder, can be measured bulk density of abrasive measured.
2. The main technical parameters
2.1. Measurement error: ≤ ± 0.02g / cm3 .
2.2. Measuring cylinder volume: 200 ± 0.5cm3 .
2.3. Dimensions: 230mm (long) * 250mm (wide) * 425mm (high) .
3.1. The instrument should be installed in a stable work surface.
3.2. The adjustment of three levels of adjustment screw on the chassis so that the chassis is level.
3.3. Adjust the height adjustment screw, so that the distance from the end face of the lower end surface of the measuring tube funnel maintained in a predetermined range (76 ± 1mm) within.
3.4. Adjust the height adjustment screw, change the direction of the funnel, so that the center line of the funnel and measuring cylinder coincide.
3.5. After the installation is complete, the instrument should avoid strenuous vibration.
4. Measure the calibration tube
4.1. Weigh the dry measuring cylinder and a flat glass (blade) of the total mass.
4.2. The measuring cylinder filled with distilled water, carefully scraped off with a scraper measuring cylinder at the top of distilled water, measured at the top of the blade against the cylinder. When the glass blade in place, wipe dry excess distilled water, called total quality.
4.3 calculated measuring cylinder volume:
V = M 0/ P H2O
Where: V - measuring cylinder volume, unit: cm3;
M0 - Distilled water quality, unit: g;
P H2O- Distilled water density in a certain temperature range, unit: g / cm3.
4.4 factory measuring cylinder volume has been calibrated (see specific data verification certificate).
4.5. The measuring cylinder volume should not exceed one year calibration cycle.
5. Measurement Methods
5.1 Sample Preparation: The test sample placed in an oven at 1100 C and dried at a temperature of 1 hour, cooled to room temperature before measurement.
5.2 250mL beaker filled with an abrasive test. Close the hopper discharge port and export center measuring cylinder is placed. The abrasive is poured into the funnel, open the discharge valve of the funnel abrasive free fall until all streams finished, This process should avoid vibration.
5.3 scrape with a ruler measuring tube has excess abrasive, when the scraper ruler and measuring about 45 barrels catchy plane0 Angle, perpendicular scratch four times. This process should prevent compaction measuring cylinder abrasive, avoid vibrations and then weigh bucket measuring quality abrasives.
5.4 Bulk density is calculated as follows:
Where: P ap - Bulk density of the sample to be tested, unit: g / cm3;
m1 - Quality measuring cylinder abrasive, unit: g;
V- measuring cylinder volume, unit: cm3.
5.5. A sample measurement should be repeated three times, the arithmetic average of the three measurements as a result of the test sample bulk density values.
5.6. The results of the same operator using the same instrument repeated measurements, the error should not exceed ± 0.02g / cm3.
