OPERATION OF THE VIBRATING MACHINE :



The equipment is illustrated in the General Assembly drawing. The number given against the components of themachine in the description below pertain to this General Assembly drawing.

The vibrating machine consists of a vibrator mounted on Springs to carry the cube mould (5) and a revolving eccentricshaft. By means of a balance weight beneath the base plate attached rigidly to the frame, the centre of gravity of thewhole machine, including the cube and the mould, is brought either to the centre of the eccentric shaft or within adistance of 25mm below it.

The eccentric imparts an equal circular motion to all parts of the machine and the mould, the motion being equivalent toequal vertical and horizontal simple harmonic vibrations, 90 degrees out of phase.

The minimum running speed of the machine is well above its natural frequency on its supporting springs, so that theamplitude of vibration is independent of the speed. The drive is by means of an endless belt running on a crownedpulley on the motor (7) and crowned pulley on the vibrator, one belt guard(6) is clamped on the base to cover the beltfor safety. One hopper (4) is clamped on the top of mould and one screw with handle is provided for clamping themould. The electric motor (7) is mounted on the base with the help of ant-ivibration rubber pads. The main base isprovided with leveling screws (8) with clamping nuts. Tension Spring (3) is mounted on main base to give tension tothe vibrator. The ON/OFF switch and digital timer for starting or stopping the machine is fixed on theframe of themachine.

Setting Up:

Set the machine to the firm level with the help of leveling screws(8). Set the machine for tension of belt,alignment of motor pulley andCrowned Pulley of vibrator by adjustment of holts (2), (1) and (3) to keep themould with base vertically over the springs. Remove the hopper (4) and cube mould (5) by unscrewing thenuts and clamping screw for mould. Apply grease lightly to all the four inside faces of mould and base plate.Mount the mould with base plate on the top of vibrator under the hopper (4). Tightly fit the mould andhopper with nut and side screws for mould. Hopper should not be removed until the completion of thevibration period.

Moulding andCuring of Specimens

Take standard sand of white variety 100% passing 2mm IS Sieve and 100% retained on 90 micron IS Sieve

(Ennore Sand has been standardized. Refer to IS : 650 ).

For each cube weigh cement, sand and water separately as follows:

Cement 200gStandard Sand 600gWater [P/4 +3.0]

percent of combined weight of cement and sand, where P is percentage of water required to produce apaste of standard consistency.

For determining NormalConsistency of Cement AIM-393, Vicat Apparatus is recommended. (Supplied at extra cost).



Mix weighed quantities of cement and dry sand with a Trowel AIM ± 482 for one minute. Then add the calculatedquantity of water and mix the three ingredients thoroughly until uniform color of the mixture is obtained. If uniform color is not obtained within four minutes reject the mixture. Prepare another mixture. Gauging time is very important., itshould not exceed 4 minutes. Clean appliance should be use for gauging.

Immediately after mixing, transfer the cement paste through hopper into the assembled mould placed in position on thetable of the vibration machine. Produce the mortar with poking Road 20 times in about 8 secs. To ensure elimination of

entrained air and honey combing. Place the remaining quantity of mortar in the hopper of the mould and prod again asspecified for the mortar first layer and then compact the specimen by vibration.

Start the machine and vibrate for two minutes. At the end of two minutes of vibration, remove the mould with the baseplate from the machine. Finish the top surface of the cube in the mould by smoothening the surface with the blade of atrowel and immediately keep it in humid atomosphere for 24 hours. After that period demould and submerge in clean,fresh water and leave there until taken out just prior to testing.Change the water every 7 days. Maintain the water at atemperature of 27ºC +/- 2ºC.

Testing Compressive Strength

Test the cubes for compressive strength at the end of 1 day, 3 days and 28 days ( see the table) which period shall bereckoned from the completion of vibration.

Test three cubes every time and take the average of the three as the compressive strength.

The cubes shall be tested on their sides without any packing between the cubes and the steel platens of the testingmachine. Apply the load steadily and uniformly at a rate of 350 kgf /cm2/min. The compressive strength shall becalculated from the crushing load and the average area over which the load is applied.

Routine checks and Adjustments

1) Adjust the base of the mould so that it rests vertically over the four springs. This can be done bymoving the spring (4) either upwards or downwards.

2) Check up the tension of the belt. It should be tight without slackness



3) The bed of the machine shall be horizontal. This can be done by leveling screws provided with thehelp of a spirit level.

4) The wheel of the motor and the eccentric shaft must lie in the same line and in the same plane (5)

5) Check the alignment of both the pulleys.

6) Check the motor connection before switching ON. If during the course of running, the belt isvibrating, then the following adjustments are suggested:

a) If the belt comes off towards outside, adjustment bolt (1) of the motor bed plate should betightened.

b) If the belt comes towards inside and touches the bearing disc, bolt(2) of the motor bedplace should be tightenend.

c) To get the tension in the belt, the spring (3) should be tightenend.

d) If there is whistling noise from the belt drive, then the plate carrying the spring (3) in frontof the belt should be adjusted either upwards or downwards and locked in position.

Working of Timer Setting Timer is very simple and easy to do. There are three keys in the front panel for setting the timerequired for vibration. One additional push switch for RESET is used to reset the timer only..

Maintenance:1) Keep the cube vibrating machine clean

2) Keep all the four faces of the cube mould lightly greased, and also the base plate.

3) Before operation of the machine, please lubricate eccentric shaft at the position marked arrow byremoving the oil filler plug.
