Batchmaster™ III automated metering system

Batchmaster™ III automated metering system

The BatchMaster III is our third generation automated metering system for use in cultured marble and solid surface batch mixing. We have combined a new control system with the best features of our previous generation batching system and added new options like catalyst and base color metering into a single system that is the most flexible and reliable on the market.

Batchmaster III automated metering system

Application: Automated Metering and Batch Mixing of Cast Polymer and Composites and other ingredients.

The Batchmaster III Automated Metering System is used to batch mix matrix for cast polymer or composites applications – including the most popular uses for making cultured marble, cultured onyx, solid surface, or other cast polymer matrix. It is also used for a variety of composites applications.

This third-generation Batchmaster adds a new control system, and new options like a catalyst and base color metering to the best features of our previous Batchmaster II technology. The result is the fastest, most accurate, easiest to use, most flexible and most reliable batch mixing system available in the marketplace.


Use of this system will reduce your labor costs, and minimize material waste from inefficient manual mixing operations.

Key features include:

Three different metering modes – Combining the best features of weight-based and volumetric metering, the dispensing system can be used in three different metering modes – Weight Gain, Weight Loss, and Volumetric. The system will store up to 20 different cast polymer matrix formulations, and mix those with push button convenience. The system also features a completely redesigned user-friendly and convenient touch screen control panel (shown at right)Resin system: The Batchmaster III uses a rotary gear pump for the fastest most accurate metering of resin in the industry. Along with the computer controlled resin heating system the operator has the ability to meter heated resin to a desired output temperature. When the resin system is in the stand- by mode the resin is recirculated through the heat exchanger to constantly maintain control of the resin temperature. If desired, additional valving can be added to the system to recirculate and heat the resin source/day tank to a second desired temperature.

Filler System: The filler metering hopper on the Batchmaster III uses a three inch core auger that accurately dispenses the desired amount filler requested. The hopper has an integrated anti bridge system to ensure accurate metering. With the addition of a weight loss scale the filler metering system will accurately meter by weight those materials that don’t normally flow well. The Batchmaster III also has the ability to operate an optional second filler hopper. This feature will allow the user to produce matrix with multiple filler combinations. Built into the metering hopper is a level sensor that will automatically activate the optional ground hopper that will keep the metering hopper filled. This ground hopper system gives the user the ability to use a bulk filler system freeing up the task of loading individual bags of filler and reducing the accompanying paper waste. Catalyst System: The most recent improvement in the Batchmaster III. The integrated catalyst system in the Batchmaster III accurately meters the desired quantities of catalyst. The system has a six gallon reservoir that allows an operator to run all day without adding catalyst. The system while in stand-by mode is continually circulating and offers a consistent blend of catalyst with immediate and accurate delivery. The pump used in the Batchmaster III is the same pump that has been used in our continuous cast machines for years.

Base Colors: The Batchmaster III base color system utilizes our time-tested and proven base color technology found in Gruber’s other continuous casting systems. In addition, rotary gear pumps are employed to continually circulate the pigment base while in the stand-by mode, minimizing any material settling and ensuring consistent and accurate material delivery. The unit also has the ability to operate two separate base color systems.
