China's top-grade CNC machine tools have achieved remarkable innovation
The Double Cone Vacuum Dryer is a batchwise dryer which handles powder product. As the dryer works in low temperature and high vacuum, it can yield high quality product. It is very suitable for heat-sensitive product.
Double Cone Rotary Vacuum Dryer is suitable for drying of materials which cannot resist high temperature, material which are easily oxidized, volatile materials which should be retrieved, materials which are strong irritants and poisonous in nature.
Double Cone Rotary Vacuum Dryer is completely jacketed, and heat transfer fluid (either hot water or oil, steam or vapor) is circulated throughout the jacket. The unique conical shape assures direct contact between the material and the heated surface so that heat is transferred rapidly by conduction.

At present, China's high-end CNC machine tools have achieved remarkable results in independent innovation and accelerated the industrialization of independent innovation achievements. It has been ranked as the world's largest machine tool consumer for 11 consecutive years, among which, metal processing machine tool consumption accounts for 45% of the global market. According to statistics, the production value of the 28 major machine tool producing countries and regions in the world was 93.2 billion U.S. dollars in 2012, and China accounted for about 30%, ranking first.
In the research and development of heavy-duty, super-heavy duty CNC machine tools, the successful development of high-end CNC machine tools, such as heavy-duty gantry five-axis linkage compound machine tools and ultra-heavy duty CNC horizontal boring lathes, has met the international advanced level and has met the requirements of aerospace, power generation equipment, and automobiles. Focused areas are focused on the processing needs of large parts; high-speed precision CNC lathes, machining centers and other products are widely used in automotive, aerospace, electronics, military and other industries, and have driven many SMEs equipment upgrades and industrial upgrading.
Jinan No.2 Machine Tool Group Co., Ltd. presses products have been fully entered into the United States General Motors Corporation, was hailed by foreign customers as "one of the world's three major stamping equipment manufacturers"; Beijing First Machine Tool Plant gantry milling and milling products have been exported to South Korea Heavy duty machine tool products of Wuhan Heavy Machine Tool Co., Ltd. have been exported to the United Kingdom, Japan, France, South Korea and so on.
In spite of this, the current CNC machine tools still have some problems that restrict the development of the industry. Wu Bolin said that in recent years, the continuous increase in imports of machine tool parts shows that the domestic machine tool parts can not meet the requirements of the host industry. Although the domestic market share of domestic machine tools has increased significantly, but the high-end economic CNC machine tools, core functional components In the domestic market share is still very low, foreign companies account for about 85% of China's high-end machine tool market share.
"The situation where most of China's CNC machine tools relied on imports has not been changed." Wu Bolin said that although there are currently some products that domestic companies can produce, the product manufacturing power is limited, and the use of imported CNC systems and functional components leads to high product prices. Competitiveness. Relative to the higher level of development of the whole machine, China's numerical control system and key functional components lag behind. If these in-depth technical problems are not resolved, the cost and price of domestic CNC machine tools will not be able to go down, and the accuracy, reliability, and technological advancement of the products will not go up.
In this regard, the key task of CNC machine tool companies is to accelerate the transformation of economic development methods, vigorously implement technological innovation, promote product structure adjustment, avoid blindly expanding low-grade, ordinary product production, accelerate the upgrading of economical CNC machine tools, and focus on the development of high-end CNC Machine tools and production lines. Enterprises should speed up R&D and master the core technologies of several high-end numerical control systems and key functional components. In order to raise the level of industrialization, enterprises must not only form a sufficiently advanced production level, but also have a certain amount of manufacturing capacity.
As the dryer rotates, the rapid and thorough intermixing of the entire batch brings every particle in contact, time and again, with the heated surface for more rapid heat conduction. This permits high speed drying without raising the drying temperature to the danger-point of the material being processed.
The most important effect of this thorough blending and is maintaining uniform temperature throughout the batch. This prevents re-condensation because there are no cold spots, and it contributes to the speed of drying and elimination of caking.
Finally, a high vacuum is maintained to draw off the moisture under these ideal conditions of material in motion.
Easy to keep clean - the interior of the dryer consists only of the smooth side walls through which the heat is transferred to the product. The thorough mixing and blending action is obtained by the unique shape of the drying compartment. Intersections of cylinders and truncated cones are obtuse angles, so no material is trapped. There are no internal scrapers, ploughs, scoops or vanes to trap and hold material while it cakes or prevents uniform warming and drying. The dryer may be easily cleaned for minimum process delay during change of products or of colors.
