SPECIFICATIONS OF “THE BOMBAY ENGINEERING WORKS” RAPID MIXER
1) MIXING BOWL
& COVER: S.S. 304 bowl design in three sections
i.e Flat bottom, Cylindrical mid portion and conical top
portion for efficient mixing operation & provided
with counter balanced lid. Lid provided with vents, view
ports & charging openings.
IMPELLER & DRIVE: The main impeller consists
of dual speed 750/1500 synchronous dual HP TEFC motor,
coupled through a belt drive to a worm reduction gearbox
with chain coupling. The impeller is designed to provide
mixing at the bottom and at the centre of the bowl and
is driven through a specially designed bearing housing
that facilities inside wash facility for quick change
over and also prevents leakage of powder from bottom entry
and leads to longer life of gear box.
CHOPPER: The chopper drive consists of dual
HP Dual speed (1440/2800 synchronous speed) TEFC MOTOR.
The motor shaft is of S.S. and the chopper has specially
designed 4 blade S.S. Impeller. The shaft is integral
with the motor. The assembly mounted horizontally into
DISCHARGE PORT: The discharge port is mounted
horizontally into the bowl with vertical downward opening.
The opening is operated by pneumatic cylinder and discharged
can be regulated for required opening.
MOUNTING: A sturdy M.S. channel frame is used
to house the drive assemblyat the bottom. The bowl is
mounted on the top. A S.S. staircase and railings are
provided for the platform. The platform is half covered
with S.S, dimpled plates. For safe movement of operater
and the area under the bowl is covered with S.S.
The entire body is covered from the sides by suitable
NOTE: For RMG 25,
Which is a lab model working platform, staircase and railing
is not provided. The operator can ascess the machine from
the ground level of the machine. Also the entire mounting
is covered with S.S
CONTROL PANEL: The control panel is mounted
on platform and is provided with
Actuators for ON/OFF , slow , fast operation.
Auto / manual controls.
Ammeter/ voltmeter for both motors.
Controls for discharge opening / closig.
Air regulator & Pressure guage & air filter.
Optionally a PLC based control Panel can be Provided.
MAIN PANEL: Main panel consisits of all prewired
connections and it has only to be connected to the electrical
supply. The circuits consists of MCCB and the relay. Wires
coming our of the connections are numbered for easy recognition.
Air purged shaft seals eliminating powder entering
Built in cleaning system for both shaft seals.
Layouts to suit indicidual requirements possible.
Machine can be provided with loading & unloading
units to form an assembly line & reduce material
handling (Optional feature)Machine can be provided
with loading & unloading units to form an assembly
line & reduce material handling (Optional feature)
Fenner taper lock pulley on main drive to reduce
vibration and better transmission efficiency.
Main Bearing Housing provided with 3 nos Oil Seals
and sleeve to minimize powder leakages / corss contamination.
Chopper motor with built in S.S. shaft to eliminate
roller, bearings and reduce maintainence.
Main panel provided with pressure switch control
for proper functioning of the machine at desired presure
of air only to prevent powder entry into impeller
and eliminates jamming of impellers.
Circuit provided with interlock contactors so that
chopper cannot operate directly , independently.
Discharge plunger provided with 3 position solenoid
valve to open and close at desired levels, thereby
regulating the discharge and preventing discharge
of large lumps.
Pneumatic circuit provided with non return valve
and water inlet./ outlet connections for facilitate
washing of the main impeller asembly without dismantling,
to facilitate faster change over.
Locking arrangement for motor to eliminate accidently
starting with open lid.
Enclosed movinf parts.
PNEUMATIC SYSTEM: The pneumatic systems requires
air pressure of 3 to 5 Kgs/sq cm. It is used for Operating
the discharge valve(opening & closing) Air purging
of chopper drive and main impeller drive to prevent cross
contamination. The system consists of an air filter pressure
guage a 2 way solenoid valve (for discharge valve) and
other pipes ferules & pneumatic fittings.
