6 VERTICAL ROLLER MILL SUPER HYBRID MILL Without taking the coarse powder of inadequate particle size out of the pulverization system, the fine powder or ultra fine powder of required particle size can be produced continuously and in a short time. Employing a dry pulverization method that eliminates necessity of water treatment, the peripheral equipment can be simplified. Applying fine ceramic to the powder contact area, the material is finely pulverized with less contamination. Using computer control of the classifier, variety of the particle size can easily be controlled. According to the size of the pulverizer, materials from the size of 3mm (for a small mill) to 10mm are efficiently pulverized. Using low power, substantial energy saving is achieved. The power loss which turns into heat is less, so the product powder is kept at low temperature (around 40 C). The Super Hybrid Mill was developed, converging the essence of powder technologies owned by Ishikawajima- Harima Heavy Industry and Nisshin Engineering. It produces ultra fine powder of sub micron size continuously and in quantity. It's an epoch-making, advanced machine having a built-in, high accurate classifier that ensures 100% collection of product particles. Specifications Super Hybrid Mill Outlook modified turbo classifier Roller Table Oil pressure cylinder Product Classification air Powder return Air Raw material The powder pulverized in the pulverizing zone of the vertical mill is thoroughly dispersed by the air flow (blown up by the air inside the mill), then carried into the classifier, where the fine powder is sent outside and the coarse powder is returned to the pulverizing zone to be pulverized again.

7 MECHANICAL PULVERIZER - SR Series MECHANICAL PULVERIZER - BM Series SUPER ROTOR BLADE MILL Pulverization of µm size which was the range of JET MILL is now possible to be executed by this system. Thanks to its mechanical system, pulverization is achieved at low cost. While pulverizing the material finely, it can prevent excessive pulverization which causes unnecessary fine particles to be produced, so the product, which has narrow size distribution is efficiently produced. The pulverization specifications which conventionally consisted of 2 steps, i.e. medium pulverization fine pulverization, are now integrated into one process. SR-25 BM-25 Since the air flows at high speed in the unit, the powder does not cling to the unit inside and the particle size of a product is quickly stabilized, which is not disrupted even in a long-run. Coupling System of Classifier TC-15/ Pulverizer SR-15 Using the cool air generator, fine pulverization of the heat sensiitive powder (such as toner, powder coating) is easily achieved. The blade mill with a unique blade structure can pulverize the material of the size up to several cm to the powder of µm. The blade mill is ideal for pulverization of food material which contains a lot of elastic and/or fiber material. The Super Rotor - an optimal solution for finely pulverizing materials such as resin. It is a blade mill capable of efficiently pulverizing material which is elastic and/or contains fibers. The powerful spiral flow originated in the narrow clearance between the fixed liner and the rotor with a unique groove shape realizes highly efficient and fine pulverization!! The Super Rotor employs a special rotor for pulverization to achieve low running cost and stable pulverization during a long running. While executing the fine pulverization, it prevents excessive pulverization to achieve very sharp distribution of the particles pulverized.

10 HIGH DENSITY PNEUMATIC CONVEYOR SUPER DENSE FLOW Because of its low speed transportation system, damage and breakage to the object transported and wear of the transportation pipe are few. In case of mixed transportation, defection and separation during transportation are also controlled. Super dense flow, vessel type Materials with high bulk density, strong adhesiveness and high moisture which were so far said difficult to carry with low pressure air transportation system are now smoothly transported. Because of the pneumatic transportation system utilizing a pressure tank, any kind of powder can be transported long way and in volume. Because it consumes less amount of air, the power to operate the facility can be less and the terminal collection/separation device can be more compact and simplified. When changing the object to be transported, the inside of the transportation pipe can be completely blown off and no contamination is left. Super dense flow, feeder type The route of piping can be freely chosen and, therefore, flexibly adjusted to the layout of the plant. Mixing the powder with compressed air and transporting it at low speed and high density, problems of breakage and damage to the object transported and wear and clogging of the piping are solved. It is useful for the powder transportation covering from small quantity to mass quantity and long distance transportation.
