Double-piston continuous screen changer realizes a non-stopping screen changing operation by altering two pistons with double filtering areas. During production, the polymer melt is divided into two flow channels inside the screen changer housing, then conveyed through the two filters equipped with the appropriate filter medium. This filter medium consists of screen packs supported by breaker plates. Features It can match with extruders of different design. It is applicable to process with most polymers at high output. Double-channel nonstop screen changer work alternatively, which can change the screen with minimum melt pressure fluctuating and production interrupting. Two stages air vent for the hydraulic system to eliminate bubbling in polymer flow. Superior sealing system completely eliminates polymer leakage. External safety cover gives better appearance and safe protection. It is equipped with circular、elongated or U- shaped screens, for enlarged filtration area. Benefits Eliminates line shutdown thus increasing production Leakage-free process Two breaker plates design increases filtration area compared to single breaker plate design Reduced downtime & scrap Reduced inlet pressure at extrusion die Reduced temperature variations in the melt 

At current, with further penetration of the economic globalization process, the economy in China develops swiftly and violently, the urbanization process constantly speeds up, the infrastructure construction makes great breakthroughs and all kinds of project construction like highway, railway, water conservancy projects and low-income housing have been growing vigorously, which promote the further development of the economy, but at the same time, lead to shortage of all kinds of resources such as natural sand and stone aggregates. Under such condition, the mining machinery manufacturing industry welcomes new development opportunity and the development has been unusually hot.
Influenced by these two factors that the government increases the investment and construction of low-income housing and of the development tendency of low carbon and green world, large-sized and green mining machines has become the first choice for industrial development. Based on the present situation of mining machinery industry, the mining equipment industry in our country should further deepen the reform, actively adjust the industrial and product structure, transform the economic growth method, enhance independent innovation ability and move more quickly to the research of high-end mining equipment, ore beneficiation machines, crusher equipment and key spare parts and market expansion. On the other hand, the relative companies should further improve the product quality and strengthen the service awareness and improve the comprehensive competitiveness of the whole industry. The innovative ability of the products is the most important factor determining the position of the mining companies in the global competition, especially for the mining equipment industry, it needs innovation more and develops environmentally-friendly and energy-saving mining machinery equipment.
As the professional mining machinery manufacturer in China, Zhengzhou Vipeak thinks that if the mining machinery industry wants long time of development, it should keep up with the pace of time, actively adjust and optimize the industrial structure, not only continues to produce the traditional mining machinery industrial advantages, but strives to develop knowledge and technology intensive industry and high-tech industry in order to promote the upgrading of the mining machinery industry. Our company is able to manufacture all kinds of production line such as stone crushing production line equipment, mechanical-sand manufacturing production line machines, and industrial powder making production equipment. The stone crushing production line equipment adopts new type energy-saving crushers, accessory equipment and electricity control system and provides a complete set of configuration with high cost performance. The mechanical-sand manufacturing production line machines adopts new type sand maker with high efficiency and excellent product granularity. The industrial powder making equipment is equipped with traditional Raymond mill and at the same time with new improved powder grinding configuration and advanced micro powder grinder so that it is able to all kinds of and all levels of customer needs.
Zhengzhou Vipeak Heavy Industry Machinery co.ltd,has many years' of technological power and experience accumulation of manufacturing and management of drying machines. The sand maker we researched and developed with great concentration plays an active role in the mining and ore beneficiation industry and is one of the indispensible mining crushing equipment in the mining industry. This machine has the most competitive price and the most reliable quality so that it is the top choice for the high performance crushing equipment.http://www.impactscrusher.com/ Sand Maker:http://www.impactscrusher.com/stone-crushing/Sand_Making_Machine.asp

Ferrules ensure reliable electrical connections when terminating stranded flexible wires in terminal blocks, circuit breakers or other control devices. They prevent fraying and breaking of individual wire strands. Ferrules are available uninsulated and insulated with color coded plastic sleeves for single or dual wire applications. Insulated ferrules also support the conductor, preventing breakage due to bending, wire stress and vibration. Ferrules are the preferred alternative to twisting wire strands or tinning the wire end. European Electrical Standards such as EN60204-1, and VDE 0611, specify that "Means of retaining conductor strands shall be provided when terminating conductors at devices or terminals which are not equipped with this facility. Solder shall not be used for this purpose." Conductors with tinned ends should not be terminated in compression clamps because solder will cold flow under pressure and eventually result in poor or loose connections. Because ferrules are mechanically crimped onto wire ends, it is important to use the proper crimping tool to insure an efficient connection. We have a wide range of crimping tools available to meet your ferrule and application needs. Choose from the following Altech Ferrules: Insulated Ferrules - Industry Standard Colors Insulated Ferrules - DIN Standard Colors Uninsulated Ferrules Dual Wire Insulated Ferrules Insulated Ferrule Assortment Boxes
