Dryer Cylinder The main series dryer cylinder we produced as followed:diamater from 800mm to 4000mm,face length from 1450mm to 10000mm,the material cast iron is from HT200 to HT300,ductile cast iron is from QT400 to QT600,hardness is from HB180 to HB240,the most heaviest cast iron finished production we made is 50 tons,now we could finish 20000 tons production.using the world renown pig-iron as material and mix lots of kind alloy element,we can make lots of kind grey iron

Open type headbox Design description: The distributor of the headbox consists of rectangular tapered inlet header for feeding pulp and step diffuser for distributing pulp. The evener device has two rectifier rolls in different drilling rate, of which the speed is adjustable. The articulated top lip with a micro-adjustor is used as nozzle system. The micro-adjustor has dial indicator for displaying and accurate gearbox for adjusting. The top slice is adjusted by manual worm

Hydraulic headbox Hydraulic headbox works without any air cushion. The advantages are below: 1)Headbox body, evener, and turbulent generator are made of stainless steel 2)Micro-adjustor of intelligent dilution to obtain superior CD basis weight profile 3)The parts touching stock are electrochemically polished 4)Suitable for higher operating speed of paper machine: 350-1000m/min 5)Easy for operation and maintenance

Headbox is the key of paper machine and its function is supplying uniform and steady pulp flow to paper machine wire part. Different pulp, different machine speed, different flow the design of headbox is different. So when choose headbox, please pay more attention. Our company design and produce headbox according to the informaiton of our customers’ paper making machine, calculate and design with the help of computer. Thus our headbox can meet customers’ requirements and

Cylinder Mould Usage: paper making, or thicking for pulp Structure type: welding sheet-rounded, perforated sheet with rods, suction, or vacuum Material available: CI,copper, or SS Dia.available: Ф1000,Ф1250,Ф1500,Ф1800,Ф2000 Face length available: 1000－5000mm

Paper Making Cylinder Mould Technical parameters: Different usage type: Paper making cylinder mould, concentrate cylinder mould. Different structure type: Common, air exhause, vacuum.
