Inert gas protection airflow pulverization classifier (nitrogen protection powder equipment), a special pulverization classification apparatus for manufacturing production is customized for various material requirements. Inert gas protection special airflow pulverization grading machine has: full closed circuit design, nitrogen protection isolate oxygen, high pulverized grading precision, uniform particle size distribution, and high yield.
Airflow classifier and cyclone trap, pulse dust collector, air blower, and control cabinets form a set of hierarchical systems.
The material is moved by the new grading machine inlet with the rise airflow at high speed to the fractionation area under the fan pumping force, and the powder of the gas solids two-phase fluid will be mixed under the power of the hierarchical turbine generated by high speed rotation. Separate according to the size of the particle size, the fine particles required by the particle size are separated by the dividing wheel blade gap into the cyclone separator or the dust collector collection, and the material entrained portion of the material entrained portion that does not meet the particle size is partially in the action of the centrifugal force and the mounting wall. The wall drops to the secondary tuyere, the strong isolated by the secondary wind, separating the thick particles, and the fine particles rises to the secondary grade of the fractionation area, and the crude particles fall to the unloading port.
The airflow classifier is novel, originating from the advanced turbocharging structure of Germany, combined grade, collected, control integrated design; advanced grading structure can achieve ideal particle size, product particle size Adjusting between 2 ~ 150μm; the structure of the new generation of graded impellers and the grading flow field design, the grading wheel can choose a variety of wear-resistant materials production; more suitable for crude material separation, increase efficiency than 15 to 30% of ordinary new grade machine; system closed Running, equipped with advanced pulse dust removal, no dust leakage of production line, low noise, clean production process.
Airflow classification machine is high automation, the control cabinet contains each control, detection, protective electric parts, easy to operate, easy to understand; multi-purpose design, can be used with new grade machine, crusher, airflow pulverizer, ball mill, modification The machine is used in series, producing the particle size distribution concentration, ultrafine finished particle size; mainly used in the production process of metal mineralization, the ore is granularized according to the settlement speed of the ore product particles. The airflow classifier is composed of a transmission, a spiral (left or right) sink, a lifting device, a lower mount, and a feed opening.
The airflow classification machine is tilted, and the inclination size is determined according to the device configuration in the process flow. The transmission drives the spiral to rotate in the groove, and the abrasive slurry is from the side.The feed feed port enters the slot, then a slurry settling zone is formed at the lower end of the groove, and its surface area and volume are determined in the sink tilting angle size and overflow metric. The low-speed rotary spiral can be a mixture, and the ore tissue is stirred, light, fine particles suspended above to form overflow, overflow from the end surface of the water tank, flow into the next mineral order; the heavy particles are sinking the bottom formation of the groove Sand, is transported from the spiral to the discharge port.
Since the reform and opening up, China has adhered to the basic national policy of opening up to the outside world, open the national door to engage in the construction, and gradually form an external open pattern in all-round multi-level wide fields. The relevant leaders of the state have also said: "Comprehensive development of the world's development trend, economic globalization is the trend of the era of irreversible." Shandong Alpa Powder Technology Co., Ltd. As a professional powder equipment manufacturing enterprise, the Dongfeng of the policy is formed. Sales network throughout the world, with a number of overseas companies, products are exported to Australia, South Africa, Indonesia, Arab, Thailand and other regions.
