Pelletizing Systems for Glass Fiber Compounds

Glass fiber compounds have traditionally been produced by strand pelletizing; however, recent trend shows movement toward underwater pelletizing.

LWCP

The LWCP System concept was designed to allow the user to operate the production machine on a continuous basis and to increase output without interruptions from a defined minimum throughput up to the maximum line throughput. Start-up waste is reduced to a minimum.The multidirectional polymer diverter valve has been integrated in the pelletizing process. This polymer diverter valve includes at least one further diverting option in addition to the already-known two diverting possibilities. It permits either a very fast changeover between two product flow directions or the sequential operation of several pelletizers connected to one and the same polymer diverter valve. Because of the “online” switch over of the running system, interruptions can be largely avoided, and with the appropriate selection of the two pelletizing heads, a very wide throughput range of the production machine has become possible.

Bidirectional Polymer Diverter Valve (BiPoDV)

With the bidirectional polymer diverter valve ( Model BiPoDV), the melt is diverted sequentially into different directions. This means that, depending on the requirements of the job, the machine operator can work with two pelletizing heads that can be individually configured. The operator can prepare the machine for the next task and assemble, heat and tighten the ideal pelletizing tools under full production conditions. All connecting channels are freely accessible so the most recently used channels can be thoroughly cleaned. For product change, the polymer diverter valve housing is rotated and lifted into the new production position so melt flow is directed to the new fully prepared tool. The change of melt direction for the next production job can be readied in very little time and without tools. A lift-and-rotate mechanism makes it possible to change to a fully prepared and heated die plate at the operative machine within minutes.

Dual Canister Filter System

The dual canister filter provides extra process water filtration in high production situations where shutdowns are kept to a minimum or when processing highly filled products that create fine particulates not caught by a standard fines removal screen. The dual canister filter assembly is located after the process water pump in the tempered water system. Its purpose is to filter any fine particulates that may not have been caught in the standard water system filtration screen. Most customers requesting this feature wish to eliminate unnecessary downtime for cleaning or for extra protection when pelletizing heavily filled products that cause fine dust. This system is typically used on pellet production lines running 250 gpm (60 m³/h) or greater. The system consists of two stainless steel cylindrical housings, each containing a screen basket with 100 – 200 micron mesh bag. Valves and piping complete the system, as well as appropriate electrical controls. This filtration system can be programmed for an alarm to sound for manual filter changing or, in most cases, fully automated changing from one filter to another. One canister is in operation while the second is being prepared or ready for use.

Fines Removal Sieve (FRS)

The Gala FRS removes fine particles >0.15 mm from the process water. Clean process water prevents product contamination and the settling of fines in key system components. The curved screen and collection basin are made of stainless steel. A self-priming pump and internal piping may be used to convey process water from the dryer and over the curved screen. If the gradient is appropriate, gravity feeding will be sufficient. The process water contaminated with particles is first conducted into a holding chamber and then flows evenly over the curved screen. The fines >0.15 mm are separated and collected in a collection basin. The filtered water is recirculated.

Band Filtration (BF)

The Gala Band Filtration System (BF) is designed for the pellet production line where there are several color changes throughout the day, and for the system used for cutting a product that creates fines resulting in contamination in the process water system. The operator do not have to monitor the system, the advance of the filter media is automatically activated in order to catch all fines down to 20 µm created before the process water becomes contaminated. In most of the cases, the water does not need to be replaced as it stays perfectly clean. The fines are continuously separated from the process water and collected in a mud cart.

Continuous Band Filtration (CBF)

The Gala Continuous Band Filtration (CBF) is also designed as a retrofit for the pellet production line where there are fines created regularly on some products and operator attendance would normally be required to clean the IS drawer in the production frequently. After installation of the CBF, the operator does not have to monitor the system anymore. The advance of the filter media is continuous and does not need any activation in order to catch fines larger than 150 µm. The process water contamination is in most cases eliminated. The fines are continuously separated from the process water and collected in a mud cart.

Dynamic Fines Removal System (DFRS)

The Gala DFRS removes particles down to 0.14 mm from the process water. Clean process water avoids the contamination of the product and the settling of fines in key system components.The entire volume of process water separated from the pellets in the centrifugal dryer is conveyed by a self-priming waste water pump to a vibrating screen where it is continuously filtered. The fines are automatically separated from the circulating water and collected in a container outside the water tank. The water dripping from the container is recycled into the process. By actuating a valve, the vibrating screen can be by-passed so the process water is conveyed directly into the tank.

Water Box By-Pass

Developed by Gala to simplify the start-up phase of the underwater pelletizing process.

Multidirectional Polymer Diverter Valve (MdPoDV)

With the multidirectional polymer diverter valve (Gala Model MdPoDV), the melt is diverted sequentially into different directions during production. The MdPoDV is designed to allow a continuous operation of the production machine and to increase output without interruptions from a defined minimum throughput up to the maximum line throughput. The machine does not have to be stopped and no throughput related modifications are required, so only minimum start-up waste is generated. At least one additional diverting operation is integrated, in addition to diverting to the floor or production position, allowing faster changeover between two product flow directions or the sequential operation of multiple pelletizers connected to the same diverter valve.
