both planetary and revolving motion, by means of gears. It has two speeds of
140 + 5 R.P.M. and 285 +10 R.P.M. With planetary motions of
approximately 62 R.P.M, +5 R.P.M. and 125 R.P.M. +/- 10 R.P.M.
Respectively. The stand of the mixer has arrangement to raise or lower the
bowl. Complete with stainless steel bowl of about six liters capacity. Suitable
for operation on 230 V, 50 cycles, Single Phase A.C, Supply.
Briquette Mould (Three Gang)
Specification:
For casting three cement briquettes at a time for the tensile strength test on cement.
Prism Mould Three Gang
Specification:
It is supplied complete with base. All parts are marked
with the identification number for correct assembly. Each
mould is individually verified in the dimensional
tolerances, hardness, squareness, flatness & roughness.
Size: 40.1 X 40 X 160 mm
Heat Of Hydration Apparatus
Specification:
This equipment is required to determine the heat of hydration of cement as
expressed in calories per gram.
The equipment comprises of the following:
1. A wide mounted double walled vacuum flask with a stop cock 38 mm &
a insulating container for the flask
2. A Beckman thermometer (Range 5° C) held tightly by the cock
stopper in such a way as to avoid accidental contact with the stirrer
blade & the reading lens. To facilitate the easy removal the cock
stopper is in two halves.
3. A constant speed stirrer (double bladed propeller type)extended to
within 38 mm from the bottom of the flask.
4. A funnel (Gooch type) with a stem of 6 mm inner dia & a body approx
25 mm long and 25 mm dia. is fitted to the cock stopper for introducing
the sample
Fully Automatic Mortor Mixer
Specification:
The mixer has been designed to mix mortars and cement
pastes primarily to the requirements of standards. The
mixing paddle has a planetary motion and is driven by a
motor with a microprocessor based speed and preset
programs to meet all listed EN and ASTM standards,
custom designed programs or manual mode. The mode
button is used for the fast selection of different programs.
The mixing paddle revolves at a rate of 140 rpm. with a
planetary motion of 62 rpm. in low speed. In high speed,
the paddle revolves at the rate of 285 rpm. with a
planetary motion of 125 rpm. An automatic sand
dispenser is supplied with the machine and the sand is
automatically discharged. Custom design allows 6
programs to be set by the operator, where the motor
speed, sand dispenser position and duration of the mix
can be set. For the mix where the motor speed is selected
as zero, the bowl can be lowered without interrupting the
rest of the program. On the display the user can see the
mix time and the machine is equipped with lamp in order
to warn the user for critical time periods.
The Automatic Programmable Mortar Mixer is supplied
complete with:
Bowl: 5 lt (approx.)
Beater
Dimensions: 300 x 555 x 610 mm
Weight (approx.): 56 kg
Power: 200 W
JOLTING APPARATUS
Specification:
The jolting apparatus consists of a rectangular table rigidly connected by two support arms to a spindle at a horizontal
distance of 800 mm from the centre of the table. There is a projecting lug with a plane face on the upper face of the
table beneath which is a stop with a rounded upper surface. The table can be raised and allowed to fall freely on the
stop by a cam which is connected to a motor and gearbox through a V-belt an pulleys. The cam
rotates at a rate of 60 Rev/Min. A stroke counter fitted with micro-switch is provided which stops
the machine after 60 Jolts. Locating pins are provided for mounting the mould compartments
on the table. The mould surmounted by the hopper can be clamped rigidly to the
table. Supplied complete with mould and hopper. Suitable for
operation on 230 Volts, Single Phase, A.C. Supply.
A Digital Preset Counter can be supplied at an extra cost.
Spares and Accessories :
