Air Cushion Headbox for Paper Making Machinery

Product Description The headbox is a key part of modern paper machines. Its structure and properties are decisive for the formation of the paper and the quality of the paper. Can effectively disperse fibers. The high turbulence headbox produces high-intensity micro-motion, which effectively disperses the fibers, prevents fiber precipitation and re-flocculation, and effectively increases the strength of the sheet. Distribute the paper stock evenly along the paper machine. (Determining the horizontal quantitative distribution of the web) The shotcrete is stable, ensuring that the pulp speed is coordinated with the web speed. (Determining the longitudinal quantitative distribution of the web) Product Parameters   There are three main types of headbox, open type, air cushion type and hydraulic type, each has its own advantage.FormFeaturesScope of applicationOpen typeThe pulp level in the box is used to control the speed of the online pulp (pulp speed), usually by adjusting the height of the weir in the boxGenerally used in low and medium speed paper machinesAir cushion typeUse compressed air to adjust the air pressure above the pulp surface in the box to adjust the speed of the online pulp (that is, the pulp position does not change, and the air cushion pressure head is changed to obtain an appropriate pulp pressure head)More widely used in paper machines with higher speeds 2. It is also used for some medium-speed paper machinesHydraulic full flow typeThe headbox is filled during the pulp flow process Use the slurry pressure of the flushing pump, the slurry position of the high-level box or the air pressure of the air cushion stabilized head box to adjust the speed of the pulp on the Internet 3. It cannot absorb the pulsation of pulp, so it is necessary to set up a pulse attenuation device in the pulp feeding system (such as an air cushion stabilized headbox) 4. The full-flow headbox with special structure can be used as a multi-layer headboxIt is applied to the papermaking machine with sandwich screen or the new type fourdrinier paper machine or cylinder paper machine with higher speedHydraulic Full flow air cushion combined typeOn the basis of the general full-flow headbox, an air cushion stabilization chamber and overflow device are added to stabilize the pulp pressure in the box, eliminate pulsation and eliminate foamIt is applied to the papermaking machine with sandwich net and the fourdrinier paper machine with higher speedHydraulic Multi-layer hydraulicAlong the Z direction (vertical direction) of the headbox, divide the propeller and rectifier unit of the headbox into several independent units (generally divided into 2-3 units), each unit has its own slurry feeding systemAt present this kind of headbox is only used for sandwich paper machineDetailed PhotosPolishing effectFinished productCompany ProfileJiangsu Leizhan Paper TechWe are a China Based engineering company and machinery supplier committed to offer complate solution and provide high-cost-performance equipments related to stock preparation and paper-making industry.For years,we have insisted on taking customer's value as our center and having strict quality-control and innovation in the whole process.With advantage technology and excellent equipment,we provide one-stop service from consultation,process design and optimization,manufacture,installation,commissing and personnel training and so on.At the same time,we can supply all kinds of stock preparation and paper making equipment and accessories.Besides,we can custom design according to customers' requirements.Our products have reliable quality and superior performance and have been exported to Poland,Greece,Turkey,Iran,India,Packistan,Bangladesh,Thailand,Indonesia,Philippines,Malaysia,Vietnam,Mexico,Guatemala,Costa Rica,Columbia,Egypt etc.We have established long-term cooperation relationship with many paper mills and agent.Honesty,cooperation and win-win are important to us.We insisted on serve our customers with high quality products,sincere service and good reputation.We are appreciated for the long-term trust and favor from our customers.Hope we can cooperate sincerely and make progress together with our new and old customer.Customer's satisfaction is our goal !   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
