How Automatic Viscosity Bulk Mixing Stations Work

The process begins with 5-gallon buckets or 55-gallon drums of adhesive and solvent loaded into the cabinet. These containers are connected to fluid transfer pumps. A preset ratio of each material is then pumped into a separate mixing tank inside the cabinet. 

The materials are agitated for a predetermined time to create a homogeneous mixture that is transferred through a viscometer to measure its viscosity. Based on the target viscosity setting, additional adhesive or solvent is continuously added to the mix until the desired setpoint range is achieved.

Specs & Features

The AMI Bulk Mixing station with automatic viscosity control can be configured in several ways. A standard system capable of mixing and controlling the viscosity of two separate materials includes the following:

• Two 20 Gallon Stainless Steel Mixing Tanks
• Integrated agitator for thorough mixing

• Two 5 Gallon Material Load Stations
• Drum cover and integrated agitation for efficient loading

• Two 55 Gallon Solvent Load Stations
• Pickup tube for easy solvent dispensing

• Six Stainless Steel Body Diaphragm Pumps
• Durable and reliable pumping system

• Two 10-gallon pressure Pots for Mixed Materials
• Feed daily spray application
• Pneumatic agitators for consistent mixing
• Level sensors for automated monitoring

• Integrated Viscosity Control and Level Monitoring
• Ensures optimal material properties and prevents overflow

• Mixing Tank Vent with Flame Arrester
• Safety feature for flammable material handling

• Output Material Filter Module
• Maintains material purity and prevents contamination

• Recirculation System with Pressure Pot Integration
• Prevents materials from settling during system downtime

All the above items are common standard features. These systems typically integrate with a spray system control package. However, we can provide an individual control package for mixing and monitoring viscosity and material levels as an "offline" option.

Standard safety features include:

• 100% Exhausted Containment Cabinet
• Manual Water Fire Suppression System
• Options for Automatic Temperature Activated Water or CO2 Suppression
• Cabinet interiors are rated as a Class 1/Div 1 environment. We utilize suitable components for this specific setting.

Customization options:

• Flow Sensing
• Density Measurement
• Temperature Sensing inside the cabinet (depending on application)
• Pneumatic Lid Lifts for the Pressure Pots

Automatic Viscosity Bulk Mixing Station FAQ

• What is the maximum amount of raw and mixed materials inside the cabinet?

  The maximum amount of raw materials you can store inside the cabinet is 110 gallons of diluent and 110 gallons of base material. As for mixed materials, the cabinet can hold up to 30 gallons of two separate materials that are mixed and ready for use.

• How long does it take to mix a 20-gallon batch of material?

  The mixing time depends on the difference between the received raw material's centipoise and the mixed material's desired centipoise range. On average, it takes 1 to 2 hours to mix a 20-gallon batch of material.

• Does the system need to be connected to a spray machine, or can it be a central point for mixing materials?

  The Automatic Viscosity Bulk Mixing Stations can be integrated with one of our spray systems or used as a central mixing point for multiple systems. Customized versions with separate control packages are available. These versions enable the simultaneous mixing of multiple batches of the same materials for several systems. Both setups are practical and commonly used in various applications.
