In this case, batch processing is the only way. When selecting a blender for powder mixing plants, consider these eight points, which refer mainly to the case for batch processing given this is an expanding area of consideration. 1. Powder characteristics. A free-flowing powder with similar ingredient particle sizes will mix easily.
Due to the significant number of complicated variables, which are constantly altered by changes in environment and materials, powder handlers implement a variety of process designs and plant layouts. Dust conditions and the methods of control are affected by production techniques and technologies, system options and equipment choices, as …
Static electricity, also known as "triboelectricity," is created when two materials rub together. 1 This friction generates a static charge, which can have costly and even dangerous consequences in today's technology-driven world. Uncontrolled static electricity can lead to electrostatic discharge (ESD) and various associated problems, including fire …

Many commercial products are handled as powders at some point in their manufacture or during end use. As a result, efficient powder handling underpins the success of many industrial processes, from bulk …
A food product plant had been running a spray dryer and other powder handling processes for over 30 years without any fire or explosion incidents. However, between midnight and dawn on a Friday morning, a fire erupted from the powder bed in the spray dryer, which ignited the airborne dust at the discharge end of the dryer.
The main function of a bulk material handling system is to continuously transport and supply bulk materials to units in processing plants. Secondary functions include storage and blending. In a typical bulk material handling system, raw materials (such as bulk solids and powders) are received from trucks, ships or trains.
Dry powder handling machines, by their nature, are difficult to seal. The traditional method is to use either packing, air purge seals, or in-face and other mechanical seals.. With all these methods, the product contacts the sealing element and leads to accelerated wear of the sealing components and the shaft/sleeve of the machine.
In his article from February 2016, Tim Freeman of Freeman Technology Ltd. explains industrial processes rely on efficient powder handling to be successful. He also outlines the benefits of uniaxial testing, which he says " opens up new opportunities for powder processors looking to improve process efficiency and product performance."
For some historical context, when Powder & Bulk Solids published its first issue in 1983, Ronald Reagan was completing his first term as US president, and the global economy was starting to emerge …
With powder processing experience since 1883, Sturtevant, Inc. is the leading family-owned manufacturer of material processing equipment operating a full-service test lab facility to analyze material characteristics,verify particle size requirements and specify the optimal equipment for a specific application.
Wear and deflection further open clearances and leakage paths in seal technology. A larger leak path allows for more powder or slurry to leak. Process leakage causes a host of problems, including: Wasted product; Housekeeping issues, with product leaking onto floors; Slip/fall hazards; Bacterial buildup and other sanitation risks
History has proven airborne particles can be extremely hazardous, resulting in deadly explosions and fires at processing and manufacturing plants. A study done by the U.S. Chemical Safety and Hazard Investigation Board looked at 105 incidents from 2007 to 2018 where dust was involved in an explosion or fire.
The low-temperature drying process that can be achieved with a vacuum-rated blender is ideal for heat-sensitive materials prone to thermal degradation when exposed to elevated temperatures. The …
The International Powder & Bulk Solids Conference & Exhibition, also known as The Powder Show, was held April 25-27 in Rosemont, Illinois. More than 3,000 attendees and more than 350 exhibitors participated in the event, with many exhibitors commenting that traffic on the show floor seemed to be approaching that of the most …
Many dry bulk materials generate dust during handling. The unloading process should be designed to minimize dust emissions during transfer from a small or bulk bag to a downstream process. It is important that processors consider dust emissions when selecting either a bag dump station or a bulk bag unloading system.
40 Years of Dry Processing and Bulk Solids Handling: Challenges, Changes, and Successes. Bulk solids science has advanced significantly over the past half a century, yet there is much more to …
As a food or beverage processor, you'll encounter many types of bulk and powder handling situations within your manufacturing process. Our articles offer best practices as well as innovations for your bulk and powder handling needs.
The process involves atomizing a liquid slurry containing active materials, binders, and additives into fine droplets, which are rapidly dried to form spherical particles. The resulting powder exhibits controlled particle size distribution and excellent morphology, making it ideal for electrode fabrication.

More than 70% of all products contain ingredients that are handled in bulk solid form at some point during their production process. Even with all this handling, many of the most basic fundamentals of bulk solids handling remain poorly understood — largely because our STEM education typically only focuses on handling liquids and gases, and …
Industrial operations that are prone to fires and possibly explosions due to self-heating include powder drying/heating and its subsequent processing, handling, packaging, storage and transportation. Typically, powder-drying operations involve the application of heat to a solution, wet powder or slurry.

Figure 3. The smart refill concept. The middle plot of Figure 3 shows motor speed versus time. During the early portion of the gravimetric feeding phase motor speed is relatively constant since density within the metering zone of the feeder, while higher than at later times in the feeding cycle, does not vary substantially.
The powder flows from the bottom outlet of the floor hopper through a pickup adapter into the two-stage pneumatic conveying line. The first vertical section rises 90 degrees from the hopper outlet and connects to the second horizontal section. This second section runs from the silicon unloading area to the main processing area.
