Processing Battery Slurries with Silverson High Shear Mixers
Silverson Machines’ latest video has been produced in response to an increasing number of their high shear mixers being specified for the processing of battery slurries. This video aims to give viewers more information on how Silverson mixers can be used for this relatively new application.
The main benefits of using a Silverson to create a battery slurry stem from the positive mixing action of the mixer. This action ensures an agglomerate-free dispersion and accelerates the solubilisation of binders, dramatically reducing mixing times and ensuring a stable end product. The precision-engineered Silverson workhead will also ensure that active ingredients and additives for conductivity are finely dispersed into the medium. This results in a homogeneous slurry with a fine, uniform particle size.

Hart’s door solutions for airports Understanding the thermal loop
Heat treatment processes are a crucial component of many manufacturing processes, but precise control of temperature requires more than just heating control. This is where the thermal loop comes into play. Thermal loop solutions have become increasingly popular for achieving improved temperature control and consistent outcomes, but what exactly does the thermal loop mean? In this article, Andy Selvy, chief system designer at industrial technology company Watlow, offers his insight.
A thermal loop is a system designed to precisely control the temperature of an object, fluid or gas. It comprises a closed loop system with vital components, such as an electrical power supply, power controller, heating element, temperature sensor and process controller. The electrical power supply furnishes the necessary energy for heating, while the power controller modulates the power output to the heating element. Subsequently, the heating element raises the material’s temperature, and the temperature sensor gauges the temperature. Ultimately, the process controller fine-tunes the power output to sustain the desired temperature for the specified duration, ensuring improved temperature control and consistent results. In some cases, a single component can play multiple roles.
For example, with high temperature coefficient of resistance (TCR) materials, it’s possible for a single component to act as both a heater and a sensor, which cuts down on the total number of components and wires needed in the system. Altogether, these parts create a system known as a thermal loop that can maintain process temperatures automatically through time.

Airports are the most intense transport links of all with the cycle of arrivals and departures creating a sometimes hectic atmosphere writes Doug Hart, chairman, Hart Door Systems. Our latest contracts were for Speedors, our high-speed door variant, for a major airport in North East England and for Aruba, one of the Lesser Antilles islands located in the Southern Caribbean Sea.
The connection between these two airports and over 40 other international airports is Hart’s airports range of specialist doors which are focused on baggage management on conveyors, fire security and high speed access controls for vehicles, baggage and people. There are two entirely separate areas in airports – passenger side and air side – both require security and access with significant systems control interface as demanded by increasing need for safety and fire protection. As a result of the increasing need for automated high security and fire separation, individually or collectively, Hart developed operating systems to be able to consider integration of doors into the building security and management systems along with standards compliance. Using these allows zones to be secured from intruders, delivering attack, threat and fire-spread prevention as well as safety for the public and even contributing to an airport’s environmental strategy through the doors’ energy saving qualities. Hart has solutions for baggage conveyor systems incorporating doors that provide security, frequent action, with high speed options that prevent smoke and fire spreading again helping airports with their green foot-print by saving energy. This unique level of product specialism for airports comes from a policy to drive door systems development and product testing that ensures the systems produced by Hart are practical and work as specified. At Jeddah’s King Abdulaziz Airport Hart completed its largest airports order by delivering 177 fire and security shutters for its new baggage conveyor system. Specifically two-hour fire seals were provided on openings in the Terminal’s firewalls. Further as the baggage conveyors passed through the firewall openings it was necessary to seal above the conveyors and also from underneath and the sides to prevent fire penetration. These implications required Hart to complete a further fire test of a completed assembly to UL standards, a World first. Conveyor doors, by their very nature, are small doors however many examples of much larger doors have been completed for instance an 11m wide door at Gatwick duty free area and 16 No. 8m wide fire doors to Baghdad airport’s Babylon terminal which demonstrate the potential size range involved. Recent contracts include Bergen Airport where Hart supplied high speed fabric doors to the baggage handling areas together with security shutters to internal areas. The baggage handling doors were supplied individually as complete assemblies pre-wired on self-supporting frames which were bolted into place on site and plugged in on site, ready to operate with necessary interface connections to conveyors etc. This method saves lots of time on site providing a very efficient installation. Other Hart current projects meanwhile, Gatwick is replacing all conveyor doors on terminals north and south. Heathrow terminal 2 following a review of security and reliability is upgrading to a Hart design to all their check in doors. Returning to my original comment about ‘control’ in airport security and safety, both are paramount and door systems play an integral part in achieving this. Working with key international players in the Airport conveyor market Hart has invested considerably in conforming with all relevant British and American standards to focus on the global sector. This unique level of product specialism for airports comes from a policy to drive door systems development and product testing that ensures the systems produced by Hart are practical and work as specified.
