The large-scale horizontal screw discharge sedimentation centrifuge developed by Chongqing Jiangbei Machinery Co., Ltd. is D7NC. It has been trial-tested by empty vehicles recently. The technical indicators have fully met the design requirements, marking China's largest horizontal spiral centrifuge. Successfully developed.
The machine is developed according to the requirements of the PVC resin market for large-volume centrifuges. It is the largest size bedroom centrifuge in China. Compared with D6NC and D5MC centrifuges, the D7NC centrifuge is more reasonable in design and more suitable for users. The need for scale production.
According to statistics, in 2005 China's demand for PVC resin reached 8 million tons, while the domestic century production capacity was only 6.5 million tons. It is estimated that by 2010, China's demand for PVC resin will reach 12 million tons, so the demand for horizontal screw centrifuge products with large specifications and large processing capacity will increase greatly in the PVC market.
Flexible Flap Disc
Flexible Flap Disc is suitable for polishing of stainless steel, metal, metallurgy, automobile, wood, marble and other industries. It is especially suitable for the processing of stainless steel and can replace the resin-shaped grinding wheel. It has strong elasticity, high tensile and bending strength, good self-sharpening, high grinding rate, and low noise. It is suitable for welding seams in the box. Polishing of the edges.

According to the type of abrasive particles: ceramic alumina VS zirconium corundum VS alumina
According to the type of abrasive selected, the flap disc can be divided into three types: ceramic alumina, zirconium corundum and alumina.
Because ceramic alumina itself has many crystals, it has good self-sharpening, relatively neat edges, good heat dissipation, and long service life. Therefore, ceramic alumina louvers are mainly used for the grinding of stainless steel, aluminum and other hard metals.
Zirconium corundum itself is a polycrystalline crystal, with fast cutting speed, good self-sharpening, and strong resistance to high pressure and high temperature. Therefore, zirconium corundum louver blades have strong cutting ability and long service life.
Alumina: single crystal, the cutting ability begins to decline at the beginning of grinding, and the abrasive grains are not easy to break, so the alumina flap disc is suitable for the processing of common metals.
