For the paper industry, nozzles play an extremely important role in the paper making process. Nozzles are mainly used for cleaning in the paper making process. The quality of the cleaning effect determines the quality of the paper. But the importance of nozzles is often overlooked by production site personnel. In many paper companies, many workers do not really realize this. A small nozzle can often solve many problems. However, improper selection may lead to paper defects, such as wrinkling, curling, and fringing. Incorrect use of the nozzle can also cause other problems:
1) Poor cleaning effect will affect the service life of felt, forming wire and roller
2) Poor spray coverage and overlap can affect paper quality
3) Using improper nozzles leads to more water and chemical waste
4) Cause unnecessary downtime for maintenance and increase operation and maintenance costs
Leader Spray Co is not only a supplier of high-end high-precision nozzle products, but also committed to providing targeted spray solutions to solve problems for customers. In the papermaking process, we can provide customers with good consulting services and professional solutions.
Leader Spray Co now offers three types of multi-disc stripping nozzles: threaded connection, quick screw connection and self-cleaning. Through the optimized material, precise angle, large flow channel and high impact force design, it ensures that it is not easy to block and corrodes during use, and achieves the slurry peeling effect that is satisfactory to customers.
With densely distributed coverage and relatively long range, it can meet the cleaning requirements of tanks or slurry tanks of various sizes.
Paper edge cutting
The main body is available in brass or 316L stainless steel, and the inlay is available in 316L stainless steel, carbide, ceramic, ruby or sapphire. The performance of the trimming water needle directly affects the quality of paper products and is one of the key links in the papermaking process. The precision of the water needle and the level of wear resistance have a great impact on the quality of paper production and workshop work efficiency.
High pressure felt/forming wire cleaning
The cleaning effect of the wire part is the key that cannot be ignored in the papermaking process. Most of the paper defects in the process have a great relationship with the cleaning effect of the wire part. The selection of high-quality nozzle products has a significant effect on the cleaning effect and production efficiency. The common pressure for wire cleaning is 25 – 30bar, and for high-speed paper machines, it is generally used in conjunction with an oscillating device.
Dry net cleaning / thread thread cutting
The quality of drying net cleaning is directly related to the surface quality of paper products. Due to the particularity of the location of the dryer, extremely high pressure is required for cleaning, which places extremely high demands on the performance of the nozzles. Carbide or sapphire is generally used.
Low pressure spray and lubrication
Fan nozzles are generally used, and the pressure is mostly 3-5 bar. Whether the model is selected correctly or not has a direct impact on water consumption and blockage. The correct selection of nozzles has a significant effect on water saving, energy saving and spraying effect.
Starch and chemical spray
Chemical spraying occupies a large space in the production cost of papermaking. Reasonable selection of nozzles has a significant effect on improving production efficiency and reducing cost consumption.
Paper towel humidifier
In the production process of tissue paper, a lot of dust is generated, which will have adverse effects on production quality and human health. Eliminating dust has a positive effect on environmental protection and health. At this stage, spray dust removal is the most cost-effective way. Medler has extensive application experience and application cases in the field of spray dust reduction, and provides customers with the optimal configuration of dust reduction solutions and services.
