Chapter 2 Installation and Use

Loosen the cup holder, the cup by a fixing nut (silicon pads) over the center hole, and the base can be fixed!

Note: Do not shake the measuring cup is fixed as long as you can!

2.1 cylinder selection

FZS4-4 Tap density tester is equipped with a 25ml, 100 ml, two different sizes of cylinders (see annex). In order to improve the accuracy of testing, please be measured based on the weight of powder (m) and bulk density (ρ) Select the appropriate cylinder.

Cylinder volume (cm3)

Powder Weight (g)

Bulk density (g / cm3)















NOTE: To improve the measurement accuracy, choose a small cylinder volume.

2.2 cylinder installation

Depending on the selected cylinder, according to the following steps to complete the installation of the cylinder:

1) will be supporting polyurethane gasket from the cylinder slowly set into the upper portion of the cylinder;

2) The upper bracket aluminum cylinder slowly set into the upper portion of the cylinder;

3) The lower bracket with aluminum cylinder upper guide bar bracket slowly tightened and firmly fixed.


Note: Do not use excessive force, damaged cylinder.

2.3 amplitude adjustment

The maximum amplitude of vibration components of the instrument of 3mm, GB GB / T 5162-2006 and ISO3953: 1993 are defined as 3mm; instrument factory amplitude has been adjusted to 3mm.

Test Procedure 3.1 sample

1) cleaning cylinder;

2) drying the sample;

3) Enter the sample was weighed and weight;

4) All samples loaded cylinder;

5) Complete vibration;

3.1.1 Cleaning the cylinder;

With a test tube brush to clean the cylinder wall, or flush it with solvent, such as acetone. If solvent is used, it should be thoroughly dried before use cylinder.

3.1.2 dry sample;

Typically, the powder should reception state experiment. In some cases, a dry powder, if the powder is susceptible to oxidation, drying should be carried out in a vacuum or inert gas. If the powder contains volatile substances, can not be dried. E.g. can not be dried, can be directly experiment.

3.1.3 Sample Weight;

He said the proper amount of sample to be tested was measured on a precision balance its weight

All the samples were loaded into the cylinder;

The sample was loaded cylinder assembly cylinder all, pay attention to the surface of the powder is level. Cylinder assembly into vibration mechanism.

3.1.4 complete vibration;

Enter the number of vibrations on the counter panel required. Press 'Start' button to start the vibration, the vibration frequency until the set is complete, the instrument automatically stops the vibration. In practice, the powder does not recur minimum volume required to change the vibration frequency N can be determined. For similar powder, in addition to specific vibration frequency usually test and acceptance have been identified (not less than N times), the vibration 2N times can be. For the metal powder of various size, the vibration can be achieved by 3000 satisfactory results.

3.1.5 read out and input volume;

If you tap on the surface after the powder is horizontal, direct reading. If you tap on the rear surface of the powder is not horizontal, then read out the highest and lowest values, calculates their average. And through the relevant formula to calculate the test result!


1, Supply voltage should be between 200V ~ 240V, when the power supply voltage instability, or when there are glitches, should be equipped with precision purifying AC power supply.

2, This equipment should be placed smooth, firm and avoid vibration, percussion, to prevent slipping.

3, In the handling or movement, attention should be gently, and can not hit the instrument.

4, When cleaning the surface of the instrument can be used wet towel dipped in detergent wring wipe the liquid can not flow into or spill into the interior of the instrument.

5, Do not turn off power to the system instantly after opening each time opening and closing time interval should be greater than five seconds.

6, Always check protective earth cable, etc., to ensure that all parts of the system are in good ground state.

7, Vibration components belong to the moving parts of the linear bearing spilled into the powder, please clean with a brush regularly adding an appropriate amount to the linear bearing lubricants.
