Gravimetric Blenders

Our continuous gravimetric blenders are designed to provide an accurate and homogeneous blend of materials for extruder-mounted, mezzanine-mounted and central blending applications. Our high resolution weighing system allows precise low-rate additive feeding to minimize usage of costly materials.

Because gravimetric blenders control material feed by weight, they are able to rapidly compensate for variations in material bulk density. The operator enters the desired blend percentages into the operator station. Each material is contained in a separate weigh hopper with integral auger feeder. The blender’s computer continuously monitors the actual feed rate of each ingredient and periodically adjusts each feeder speed to maintain the preset blend percentages by weight. All materials then flow through a cascade mixing chamber which thoroughly

homogenizes the blend. For extruder-mounted applications, the homogeneous blend is then captured in a plug flow hopper which preserves the blend homogeneity to the extruder or other processing machine.

Benefits

Primary benefits cited for the system include: easy custom programming to meet specific requirements; new networking capabilities, both in-plant and inter- plant, the latter via internet; and 'virtually instant accessibility' for software upgrades, addition of gravimetric blenders, and frequent product changes to meet JIT manufacturing requirements.
This hardware/software package enables two-way communication between the PCs and the controllers of the builder's Weigh Scale Blenders on multiple processing machines. The system tracts material consumption by weight for each machine to provide complete plant-wide or company-wide material management.
Expanded data acquisition and downloading functions that include the ability to store up to 2000 product recipes, each of which can be identified by up to 15 alphanumeric characters. Because the system accounts for every material that passes through process machines by weight, companies can use this 'gateway' to determine part yields, isolate the reasons for 'lost' material and accurately forecast inventory requirements.
Advanced batching capabilities for the off-line pre-blending of raw materials. In addition to programmed filling of containers, the system produces customized labels with data such as time/date, weight, recipe name and percentages and individual ingredient weights.
In-plant and inter-plant communication capabilities made possible by the incorporation of transmission control protocol (TCP) and Internet protocol (IP) drivers. This includes compatibility with Ethernet (10 megabits/sec) and Fast Ethernet (100 megabits/sec) local area network (LAN) software, as well as other communication systems

Gravimetric Blenders Used in Sizing - Textile Industry

Sizing greatly influences fabric quality. Inconsistent size mix adversely affects productivity in the loom shed and leads to fabric defects. Consistently achieving homogeneous mixes in present manual system is almost impossible. But with Texcomp's Gravimetric Blender - rest assure you will always achieve the desired results.

Gravimetric Blenders Used in Sizing -Plastic Industry

Texcomp offers a range of weigh scale blenders designed to satisfy the demands of the plastic processing industry. Depending on the model, up to eight materials can be blended. Throughputs range from 200 to 5000 lbs.hr.
