Specifying ribbon blender mixer
The multi-purpose ribbon blender mixer
The classic ribbon blender mixer is a familiar sight in production floors across the food & beverage, chemical, pharmaceutical, plastic, agricultural and other industries. Due to its versatility and economy, the ribbon blender is often the best choice for most mainstream blending applications.
Engineers tasked with procuring a new blender must recognize the different features and options that are available to optimize efficiency with respect to a specific application. Customizing the multi-purpose ribbon mixer blender to meet your own process needs does not have to entail drastic costs. A simple but comprehensive review of key process details helps guarantee that your equipment is not underspecified or over-engineered.
Some blender selection and specification considerations
•The desired batch volume determines the size of the blender but product bulk density determines if a standard or heavy-duty model is required. Industry-wide, most standard ribbon blenders can typically handle bulk densities of around 600 kg/m3. More robust blenders are available for denser products. If you are producing different blends in one blender, factor in the lowest and highest densities to calculate the right blender capacity and motor size. Keep in mind that optimal mixing in a ribbon blender requires enough batch material – equivalent to at least 30-40% of the rated volumetric capacity.
•Material of construction on the wetted parts must be compatible with all raw materials that will be processed in the blender. This includes the trough, cover, agitator, discharge valve as well as the spray bar and safety grating, if any. Internal surfaces must be well-polished and each weld should be radiused to prevent material buildup.
• The most reliable drive design for a ribbon blender is a one-piece motor reducer or gearmotor. This direct drive arrangement is cleaner and more compact compared to antiquated chain and belt drives. It also reduces noise in the plant and eliminates maintenance headaches. Gearmotors are designed to work well with electronic inverters which provide enhanced speed control, overload protection and adjustable starting torques.
• The ribbon agitator can be supplied with an interchangeable paddle-style agitator which is recommended for gentler blending of fragile applications.
• To reduce dusting, use clamps to secure the gasketed cover and a dust-tight knife gate discharge valve (or a ball valve if you also need the blender to be liquid-tight).
• Install lantern rings on the packing gland when handling fine or abrasive powders. Maintaining a slight positive pressure of air during blending will prevent particles from penetrating the ribbon blender’s stuffing box and wearing the shaft.
• Testing is very useful in confirming blend quality and batch times. Ask your blender manufacturer about testing services or rental/trial programs. The latter is an excellent resource that allows you to put new ideas for process improvements to the ultimate test – in actual production.
