HOW IT WORKS
- Technical Specification
- Safety Features
VJ Instruments has Introduced the Rapid Mixer Granulator, a revolutionary machine , adapted to handle smaller trial batches for Granulator. Our new Granulator offers multiple processing providing both flexibility and cost benefits.
General Structure & Mountings
Mounting frame is made out of mild steel & SS304 and M.S. parts cladded or covered with SS304, in which drive assembly is mounted at the bottom. This frame is covered with SS304 sheet. Mixing bowl is mounted at the top of this frame. Mounting platform is covered with SS304 covers from all sides. Staircase & railings are not required in 10 Lit.
Mixing container (bowl), in which contact parts are made out of SS316 quality material. It comprises a flat base with a lower vertical cylindrical wall section and an upper conical section. A conical bowl is the natural shape for difficult materials. Light dusty powders do not float unmixed on the surface of the circulating vortex. Wet granulations do not stick to the walls, but discharge cleanly from the bowl with no product loss. Specially designed bowl is provided with lid which is having a vent, view and charging ports. Main impeller’s drive shaft is mounted directly on output shaft of the worm reduction gear box. The seal housing at main stirrer’s drive shaft may be flushed with cleaning water, which is then drained away from the machine through built in drain tubes. A high speed granulator is inserted horizontally through wall of bowl to assist blending of powder and to break the product to the granules of the required size. The seal housing at drive shaft of granulator also flushed with cleaning water, which is then drained away from the machine through built in drain tubes.
The discharge port is mounted horizontally in to the bowl with vertical downward opening. This discharge port is operated by pneumatic cylinder in . A discharge valve, which is built horizontally in to the wall of the bowl and is operated from the operator's control panel in bowl. A T/C clamping system gives unrestricted access into the chute for easy cleaning. All internal and external surfaces of the discharge valve are of polished stainless steel and very easy to clean. The design of discharge port will be flush type, which flush with inner surface of the container. Due to this design no pocket will develop at the discharge port.
Control Panel and Pneumatic system
The operating panel will be mounted on platform and is provided with following controls, in
electrically controlled panel.
• Three/Single phase indicating lights.
• Variable speed of Impeller motor & Slow & Fast speed of Chopper motor.
• Pneumatic/Manual controls for the opening and closing of the discharge port.
• Ammeters for both motors (Optional).
• Main panel provided with pressure switch control for proper functioning of machine at
desired air pressure.
• The system Consist of moisture & Oil separator with regulator, pressure gauge, air
regulator, solenoid valve and required pipes and pipe fittings.
• Homogeneous binder distribution.
• Short batch time and reduce cleaning time.
• Maximise cleaning effectiveness.
• Inbuilt Air Purging system/Manual
• Air purge sealing system for Impeller shaft and Chopper shaft. (Dry oil free air will be
provide by customer up to machine)
• All product contact parts are made out of SS 316 & polished to the mirror finish.
• A high-speed chopper is inserted horizontally through wall of bowl to assist blending of
powder and to break the product to the granules of required size.
• A high speed chopper is inserted horizontally through wall of bowl to assist blending of
powder and to break the product to the granules of un-even size. (Wet Granules).
• Chopper motor is provided with a removable stainless steel shroud, which covers the motor
and simplify cleaning.
• All moving part of the machine are totally enclosed to eliminate accident.
• The machine can-not be started unless and until the mixer cover is properly closed.
• Flush wall type discharge valve eliminates pockets at the port of discharge valve.
• Pneumatically operated (non-rotating type) material discharge valve for 5Kg containers.
• Castor wheel mounted mobile unit for easy handling (Optional).
• Top cover with facility of light glass, sight glass and air filter .
• Stainless steel air receiver.
• Air filter for compressed air.
• Granulator with U shape & knife edge blades
• Binder spraying facility with Tank facilitated with Stirrer & Spray Nozzle (Optional).
• A.C. Frequency drive for variable speed of Chopper.
• Manual/PLC based power panel & touch screen based operating panel.
|Electrical services||As per country requirement|
|Temperature Controller||Ambient to 80 C|
|Spray Gun||SS316 - 1mm bore|
*Capacities mentioned above depend on samples used and may vary accordingly.
- Enclosed moving parts.
- Machine will not start with open lid.
- Machine will not start with open discharge valve from T/C clamping.
- Rapid Mixer Granulator is designed to achieve excellent mixing and consistent granules at
lower operating cost along with higher productivity. Better mixing and closed control of
granule size leads to faster tableting speeds with improved quality and least rejections.
