Chapter 1 Installation and Use

2.1 cylinder selection

FT-100B practical tap densitometer (heap densitometer) Equipped with a 25ml, 50 ml, 100 ml, 250 ml graduated cylinder four different sizes (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 addition of silica gel pad at the bottom of the cylinder;

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

5) After installing the cylinder assembly, the guide rod assembly into the hole in the guide bearing.

Note: Do not use excessive force, damaged cylinder.

2.3 amplitude adjustment

The maximum amplitude of vibration of the instrument component to 15mm, GB GB / T 5162-2006 and ISO3953: 1993 are defined as 3mm; USP amplitude of 14mm instrument factory has been adjusted to 3mm (already added two 1mm and 1. 2mm start-up pad), the adjustment can be the Annex 1mm, 2mm or 5mm damping pad to the lower right amount of vibration components can be added.

Amplitude = total height of the vibrating pad - 1mm

Chapter II testing process

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;

6) reads and input volume;

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 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;

Press 'vibration times' button, enter the desired number of vibrations. Press 'Start' button to start the vibration, until the vibration frequency setting is complete, the instrument automatically stops the vibration. In practice, the powder volume changes do not occur in the required minimum N is the number of vibrations can be measured for the same kind of powder, in addition to specific vibration frequency usually test and acceptance have been identified (not less than N times), the vibration can 2N times for various size metal powder, vibration 3000 to achieve satisfactory results.

Adjusting the frequency of the vibration. Rotatable governor adjustment knob (lower right black knob) to select the appropriate frequency of vibration. The maximum vibration frequency of the instrument is set at 300 rev / min. In general, the vibration frequency of 100 to 300 rev / min are can.

3.1.5 read out and input volume;

If you tap on the rear surface is horizontal powder can be directly read. If you tap on the powder surface is not level, then read out the highest and lowest values, calculates their average get tapped volume. Readings, to retain an estimated value.

Press 'calculate' to complete the calculation;

After completion of the above steps, according to ρ = m / v completion density calculations.

Chapter III Maintenance

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.


Chapter IV Other Problems and Solutions


The causes of this phenomenon

To solve the problem

Vibration is not smooth

Linear bearings lack of lubrication

Adding an appropriate amount of lubricating oil

Vibrating assembly does not vibrate

Governor switch is not open

Open the governor switch

Governor tone is too low

Governor adjustment knob clockwise

Vibration times' parameter is set to 0 or completed vibration

Reset 'vibration times'
