Riddhi Mixer Granulator is designed to meet special needs of tablet manufacturing
technology. This is achieved by reducing processing time, more homogenous mixing,
Uniformity of Granule size and above all maintaining improved hygiene compliant to GMP
Machine will be complete with Mixing Bowl, Mixing Blades, Granulator, Pneumatic
Discharge, Motor, Gear Box, Operating Panel and the Control Panel.
The Mixing Bowl is cylindrical with a large diameter and flat base. The Top portion of the
bowl is conical in shape to assist circulation of cohesive powders. The Bowl is fabricated
from S.S. 316 Quality Stainless Steel with all internal and external surfaces polished to
Pneumatically Openable (except RMG 50 & 100LTRS) type lid consists of charging hole,
air filter and special type silicon gasket.
Mixing blade consisting of two Nos. full and two Nos. half blades specially designed for
intense mixing. The angles of the blades are such that half blades lift the material and full
blade pushes the material. Continuous action of this with the different ingredient
immensely mixes thoroughly with homogeneously. Mixing blade assembly is mounted on
main shaft with separate bearing housing which fully eliminate any chance of cross
contamination of product with any lubricants. The upper portion of the housing contains
specially designed Teflon seal along with air purging facility. Lower stage housing contains
bearing alongwith oil seals that make it completely leak proof.
The bearing housing of the main shaft connected to gearbox by means of heavy-duty chain coupling. Chopper
blade assembly consists of a separate baring housing coupled to motor by means of flexible coupling, with
Teflon impregnated gland packing and air seals.
A high speed Granulator is inserted horizontally through the wall of the bowl to assist
blending of powder and to break the lumps of the products in to granules of required sizes.
These lumps are formed while wet mixing.
Machine has a side discharge outlet with pneumatically operated. The discharge valve is
exactly matching the profile of the intervene bowl with perfect sealing arrangement.
Pneumatic cylinder housing is specially designed with swivel type arrangement, which
helps for easy cleaning. Safety interlocks are provided to discharge valve as well as top lid
with limit switches.
Rigid Machine base frame made from M.S. Square pipe is designed to accommodate the
mixing bowl and the control panel. The motor V belt drive and reduction gear are also
housed in the frame. The machine base is totally enclosed and removable flush type S.S
give access to motor gearbox and belt drive inside and machine base. Removable S.S. Cover
finished mirroring finish on all side of the machine base frame. Inside of the M.S. base
frame duly epoxy painted to avoid any rusting. The bottom of the base frame duly covered
with M.S. Sheet. So that any oil or dust from belt should not fall on the floor.
ELECTRIC CONTROL PANEL
All the main Circuit like Switchgears, Relays, and MCBs etc. will be contained in a S.S.
Panel box and kept in Non Flame Proof area.
SAMS make Process Unit with programmable digital timer, auto mode indicating
lapsed/balance time etc.
An Operating Panel mounted near the mixing bowl for the easy operation in the case of
NON FLP MOTOR. In FLP only Flame Proof Operating unit provided near the Bowl with
auto manual switch, Emergency stop and push buttons for main motor, chopper motor
Discharge valve open and close, ammeter for main motor and chopper motor.
The machine is supplied with duly required pneumatic systems of FESTO/CAMOZZI Make.
The customer has to ensure, supply of oil free compressed air, also free from any other
possible impurity, which may contaminate the product. Air filter and Air water separator
are also provided with the machine. Pressure regulator is provided to regulate the desired
air pressure. The systems is suitable to accept an Input air pressure of 7kg/cm2 to be
terminated at " " BSP" terminal. Air lubricator is provided to lubricate solenoid valves and
pneumatic cylinders is incorporated in the system.
A Pressure Switch is incorporated in the Pneumatic circuit to ensure that unless required
minim air pressure is available in the system the machine cannot be started. And once the
machine starts and if drop below pre-set the value the machine stops immediately. In case
the Flame Proof Machine the pressure Switch is fitted in main panel. All M.S. parts will be
cladded with SS 304Q sheet and all SS parts will be polished to smooth surface.
STANDARD PROCESSING DURATION :
