To be successful in today's global markets, manufacturers must constantly reevaluate their materials, equipment and supplies to ensure that they're using the most effective products available. Incorporating a new material or technology can often give companies a much-needed competitive edge by increasing throughput, improving a product's appearance and/or overall quality, reducing energy consumption or labor costs, or providing a combination of these and other benefits. Following are some highlights of products that have been introduced over the past 12-24 months specifically for the ceramic, glass, brick/structural clay and related industries.


Borates for Brick and Roofing Tile

U.S. Borax Inc.

This company has developed Evansite(r), a microfine sodium pentaborate in a sugar suspension that is specifically designed to meet the heavy clay industry's economic and technical needs. The sugar prevents the borate from migrating to the surface during drying, and it transforms sodium pentaborate's high solubility from a disadvantage to an advantage by allowing the borate to dissolve in the relatively low moisture content of the clay body. This ensures optimum distribution in the body and even vitrification. Once the clay body is dried, the sugar is burned off during firing, and the borate can begin fluxing. The new borate can help heavy clay manufacturers save fuel by allowing a 50-degree reduction in firing temperature. Other benefits include improved durability, compressive strength, abrasion resistance, leaching resistance and reduced porosity. Additionally, manufacturers can make more efficient use of other raw materials by adding the new borate to their batch.

Injection Molding Compounds

Tosoh Corp.

New compounds from this company are designed

to simplify high-pressure injection molding. Each compound is composed

of high-purity zirconia powders and a proprietary binder formulation (approx-imately 50 vol %) developed for the intended dewaxing environment. The company adds its proprietary binder to the powders and homogeneously mixes the formulation. The resulting taffy-like mixture is dried and pelletized to produce the injection molding compound that is delivered to the ceramic manufacturer. The company is also willing to share its experience in using the compounds with its customers, and to partner with ceramic manufacturers to develop formulations based on materials other than zirconia.

Horizontal Mixing Equipment

American Process Systems, Member Eirich Group

The new Fluidizing Paddle Blender is designed to mix five times faster than a ribbon blender and fluidize powders quickly and efficiently. The blender reportedly provides homogenous mixes independent of a large range of particle size, shape or density; less degradation than ribbon blenders; easy clean-out; efficient liquid addition; high mix efficiencies with a low coefficient of variation; and high throughput rates with low horsepower. Little heat is generated due to friction, and the blender's single U-shaped vessel and rotor design minimizes operating costs. Units are available in carbon steel, stainless steel and sanitary construction for a variety of solids-to-solid and solids-to-liquid blending applications. The company has also introduced a new ergonomically friendly Elevation Station(r), which allows mixing and blending equipment (such as the Fluidizing Paddle Blender) to be loaded and discharged at floor level, thereby eliminating the need for stairs and mezzanines.

Polymer Impellers

Norstone, Inc.

The NORBLADE impellers, which were originally cast from polyurethane for use in abrasive water-based slurries and coatings, are now available in a multitude of polymer options, including anti-static polyethylene, nylon, polypropylene and PTFE, for use in all types of systems. These impellers can replace steel impellers to reduce metal contamination and the safety hazard created by the blade wearing to a razor sharp edge. According to the company, the polymer blades are easier to change because they are lighter in weight and can't be put on backwards, and they have proven to outlast steel more than 10 times in most systems. Productivity is reportedly increased due to the polymer blades' higher axial flow capabilities, which also keep the batch cooler. The blades also feature excellent pumping properties, which enable powders to be incorporated at a much faster rate than with standard dispersing blades.

Fast Firing Brick Kiln


A new fast firing system is designed to offer brick manufacturers both high production rates and a favorable return on investment. Faster firing cycles reportedly equate to a smaller kiln and dryer and an overall smaller building footprint, which, in turn, reduces the capital cost for the system. Additionally, the system offers optimal heat exchange for the ware, which results in lower fuel consumption, improved temperature uniformity, and greater control of size and other physical properties. An open ware-loading configuration greatly enhances the ease and speed of drying due to greater recirculation of hot gases around each brick. And since each layer is only two-brick high, the firing cycle can be achieved with less breakage, no kiln marking and minimal defective product. Another reported benefit is that the fast cycles minimize the lead time for sales and provide faster product quality feedback. It has also been proven in lab tests that faster firing cycles reduce fluoride emissions. In a commercial-scale plant, this can eliminate the costly addition of a scrubber.

Temperature and Roller Monitoring Systems

Sacmi Forni

This Sacmi Group company has introduced two new systems to control temperature and roller damage in roller kilns. IRIDE (InfraRed Intelligent Device) consists of an optical pyrometric scanner, which acquires the surface temperature of ceramic pieces as they move through the kiln, along with dedicated software on the kiln's computer that processes the data. The acquired information is used to obtain a precise reference temperature for zone-relevant control and adjustment devices. The patented SPINMARK roller monitoring system immediately informs personnel of any roller breakages when special components (installed inside a non-magnetic metal tube located under the free-spinning end of the rollers) detect the absence of roller rotation. SPINMARK can be applied along the full length of the kiln or in critical zones only, providing an overview of the situation that can be viewed from both the main control panel and smaller panels located along the kiln.



High-Resolution Laser Dilatometer

Linseis, Inc.

The new Laser Dilatometer Pico - Series 0.3 nm reportedly offers resolutions up to a factor of 33.33 higher than the resolutions provided

by conventional push-rod dilatometers. This is beneficial in applications where extremely small expansions take place that are difficult

to measure with conventional push-rod instruments. According to the company, the new dilatometer is based on the interference measurement technique and uses modern computer calibrations, which enables it to provide much higher accuracies-around 0.25% up to 30 nm, compared to the typical 1% up to 100 nm achieved with conventional push-rod dilatometers. Additionally, unlike conventional systems that require infinite adjustments and/or calibration with a reference sample to ensure repeatable analyses, the laser dilatometer relies on an absolute measurement principle. As a result, the accuracy and repeatability of the measurements are not affected by external test conditions.

Particle Size Distribution Analyzer

Particle Sizing Systems

The AccuSizer 780 uses a technique called Single Particle Optical Sizing (SPOS) to measure high-resolution/ high-sensitivity particle size distributions in a range of applications. The SPOS technique makes use of light obscuration to count and size particles one at a time, thereby providing a high level of detail about the distribution being analyzed. When coupled with an appropriate fluidics system (such as the AccuSizer's proprietary Autodilution method), SPOS can accurately characterize highly concentrated dispersions for mean diameter, range and counts. It can also provide a quantitative measure of oversized or aggregated particles even when present at parts per million (ppm) concentrations. In abrasive analysis applications, the technique can be used to evaluate filters that remove abrasive particles that will scratch a surface, and it can also monitor shifts in particle size distribution due to usage and allow a process engineer to determine whether an abrasive has to be changed out.

Water Sorption Analyzer

Quantachrome Instruments

The Hydrosorb-HT water sorption analyzer features an analysis temperature range of 12 to 85°C. Both the HT (high temperature) and standard model (12 to 47°C range) have been equipped with a new two-speed stirred thermostatted bath for better temperature stability, and an indicating thermal sensor for improved operator feedback. The Hydrosorb series of water sorption analyzers reportedly brings a historically slow analysis (days, even weeks) up to speed (overnight, maybe just a few hours) through its combination of intelligent operating algorithms and accurate vapor pressure measurement. Its rugged design has done away with the need for microbalances, so the Hydrosorb is equally at home in industrial labs and academia.
