Revolutionizing Granulation: The VJ Instruments Lab Model Rapid Mixer Granulator

Explore the VJ Instruments Lab Model Rapid Mixer Granulator in this video. Discover its robust structure, efficient mixing container, user-friendly control panel, pneumatic system, discharge port benefits, and advanced safety features, all designed to enhance productivity and granule quality in smaller trial batches.

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
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.

Special Features
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.
