The "Continuous Distillation Apparatus (Three-Component System)" requires at least two columns for the separation of binary systems with azeotropic points, such as ethanol-water and IPA-water. In this process, the first column concentrates the mixture close to the reference point composition, and in the second column, an entrainer such as benzene is added to perform dehydration distillation through three-component azeotropy. Additionally, it is possible to cut the low-boiling point from the first column, purify the main distillate in the second column, and separate high-boiling substances from the bottom of the second column. 【Features】 - Typically, three columns are required for dehydration distillation, but by returning the decanter liquid to the first column, it may be possible with only two columns. - There is no liquid leakage, and the composition remains on the shelf, allowing for intermittent operation. - Bubble cap trays can operate stably against slight variations in the feed rate compared to other gas-liquid contact devices. - Separation of low-boiling, medium-boiling, and high-boiling components is possible. *For more details, please refer to the PDF document or feel free to contact us.*

The external heat rotary kiln does not allow direct contact between the raw materials and the heating gas, resulting in minimal burning unevenness and dust generation, eliminating the need for dust collection equipment. There are two types: multi-tube and single-tube. The multi-tube type distributes the raw materials and has a thin layer height, allowing heat to be transferred more uniformly, and due to the larger ratio of heat transfer area to raw material volume, the thermal efficiency is significantly improved. It can be widely used for oxidation reactions, reduction reactions, decomposition, catalyst generation, regeneration, as well as roasting, drying, etc., in various powder and granular materials in active and inert gas atmospheres.

The fluidized bed creates a state similar to that of a fluid by blowing gas into a powder, suspending solid particles, and is used for operations such as drying, adsorption, and reactions. In conventional fluidized beds, the target for fluidization was powder particles of tens of micrometers or more. However, the "vibrating fluidized bed apparatus" can form a stable and good fluidized bed even with fine powders of several micrometers or submicron size, which were considered "difficult to fluidize," thanks to the synergistic effect of gas and vibration, while maintaining fluidization with a small amount of gas. This allows for a longer contact time between solids and gases, resulting in fewer particles being ejected. It has a wide adaptability to the shape of powders and can also be applied to wet materials. Additionally, it allows for the miniaturization or elimination of auxiliary equipment. Applications include drying, filter drying, humidification, reactions, surface modification, solvent removal, and classification, and it is particularly effective as a device for removing trace solvents contained in pharmaceutical powder raw materials. Uses include pharmaceuticals, food, resin powders, graphite, toner, ceramics, metal powders, spices, and fine chemical powders, with solvents prioritized for removal being acetone, ethanol, IPA, methanol, and pyridine. There are vertical VUA type and horizontal VHA type models available. For more details, please contact us or refer to the catalog.

The "Vibration Dryer" is a unique vibration dryer that fluidizes powder and granular materials solely through vibration and dries them using indirect heating. There are two standard types: VU type and VH type. ■ VU Type This type is suitable for batch processing of small to medium quantities when there is a wide variation in the properties of the material being processed and the amount being charged due to the progress of drying. ■ VH Type This type shows stable fluidization when the charge amount is 60-80% of the dryer’s capacity. If the amount is reduced, there is a tendency for the fluidization to deteriorate, making it suitable for medium to large-scale processing with low moisture content. It can accommodate a variety of conditions and applications, including drying of nanoparticles, drying from low to high temperatures, and drying a wide range of materials from slurries to pastes. Currently, we are offering a product catalog that summarizes the vibration dryer series. *For more details, please download the materials or contact us through our website.

Inside the MCN pot, MCN balls are used as a medium, and wet crushing, mixing, dispersion, and reactions are carried out using a vibrating mill and pot mill for experimental research. Both the MCN pot and MCN balls are made of nylon, and since they are organic materials, they will volatilize during the firing process when mixed with inorganic materials, ultimately not becoming impurities. The MCN balls contain metal balls to increase their specific gravity. The MCN ball mill uses MCN balls as a medium within a nylon body to perform wet crushing, mixing, dispersion, and reactions. Since both the body and the medium are made entirely of nylon, there is no contamination from inorganic materials. We also offer models with gearboxes. For small capacity pots, please use the pot rotation stand. We standardly offer three models: single-layer with two pots, double-layer with two pots, and double-layer with three pots.

The new type of vibration mill, OD mill, places a vibration source on one side of the grinding cylinder and a balancer on the opposite side. The circular motion of the vibration source causes the various parts of the grinding cylinder to vibrate. This movement of the grinding cylinder improves the rotational direction of the grinding media inside compared to conventional vibration mills, enhancing the grinding effect. The circulation rotation speed is approximately four times faster than that of conventional vibration mills. The frictional impact force is significant, allowing for fine grinding due to its grinding effect. Additionally, the large transfer capacity of the grinding cylinder has improved continuous operation processing capabilities. Furthermore, the vibration source is a single-axis, lightweight external type, making maintenance easy. It is a low-power, energy-saving type.

The vibration mill exhibits 10 to 20 times the efficiency compared to conventional rotary mills. This is due to the fact that in a vibration mill, the number of impacts from the balls is 50,000 times that of the rotary type, and while the impact in the rotary type is 1G, the vibration mill can achieve 6 to 14G. Features of the vibration mill include reduced grinding time, ease of micron-order fine grinding, high efficiency, compact design allowing for special grinding such as inert gas encapsulation, the ability to attach a jacket for internal cooling or heating, suitability for both dry and wet grinding, ease of handling with a small installation area, and the ability to select the lining (non-ferrous metal material) and media for the grinding chamber.

The vibration mill of Chuo Kogyo Co., Ltd. is widely used across various industries, including ceramics, metals, food, pharmaceuticals, and new materials. It is not only capable of fine grinding but also excels in medium grinding, dispersion, precise mixing, disintegration, and mechanochemical applications, among others. Its excellent performance has received high praise from various sectors. Additionally, in response to the recent trend towards finer materials, we have prepared various types of materials. The vibration mill broadly belongs to the category of ball mills; however, unlike traditional ball mills that rotate a drum (grinding cylinder) containing grinding media, the vibration mill vibrates the grinding cylinder, causing the media inside to move. A fixed unbalanced weight on the shaft generates centrifugal force through its rotation, which causes the entire spring to vibrate at high speed. This vibrational energy is transmitted to the media (balls or rods) in the grinding cylinder, resulting in intense impacts and friction between the media and the inner wall of the cylinder, as well as between the media themselves, leading to fine grinding in a short time. Consequently, the grinding force of the vibration mill is significantly greater than that of conventional rotary ball mills, with values ranging from 6 to 10G compared to 1G, achieving grinding capabilities that are 10 to 20 times greater.
