S-Tron metal detectors remove both ferrous and nonferrous metals from pneumatically conveyed solids and feature a positive speed control that automatically measures metal particle speeds and adjusts reject timing and duration to minimize loss of good product. Pinch valves prevent pressure loss during discharge. These detectors use high-frequency, triple-coil detection for high sensitivity and have product-effect compensation and EMFI filters to further cut product waste. They are engineered for easy installation and work on both vacuum and pressure systems. High-speed reaction times allow for a compact, space-saving design.

The APEX 500 high-performance metal detector improves metal detection sensitivity by up to 20% over the previous generation of products. Utilizing new patent-pending multicoil technology, the system increases the effect of the magnetic field in the aperture by more than 1.5 times, enabling the detector to target and amplify signals from much smaller pieces of metal. The platform also incorporates a new shielding technique that reduces the unwanted effects from hard-to-handle, wet, or conductive products. The combination of these two design innovations, along with new digital signal–processing software, allows customers to achieve high sensitivity levels.

Particulate Processing Consultancy Service
Malvern offers a new consultancy service designed specifically to meet the requirements of the process industries. The service is aimed at helping manufacturers better understand and optimize particulate processing operations. The five-day consultancy package is built around Malvern’s Insitec Voyager, a fully automated, mobile on-line particle size analyzer that is installed at the client’s site and is fully supported throughout by a Malvern process specialist. A typical program involves installation and optimization of sampling, measurement of the current status of the process, running defined test programs, and the generation of comprehensive reports. The goals are to find the best parameters for process control and to test sensitivity to process change. There is an option to rent or buy the Insitec Voyager system after completion of the study.

The Model 141 hammer mill reduces friable and fibrous materials into uniform particle sizes ranging from 20 to 300 mesh. Centrifugal force causes pivoting hammers to stand at 90° to the rotating shaft, throwing material against breaker-plate ridges in the feed section and then against perforated bed screens through which sized material exits. The shaft, integral hammer disks, disk pins, and hammers are driven by a 75-hp motor at 1800 to 4000 rpm, achieving hammer-tip speeds of 8700 to 19,500 ft/min, even under heavy loads. This feature reduces a broad variety of solid material into particles at high rates. The mill can pulverize wood scraps, process grain, break down impact-resistant housings, destroy ammunition shells, pulverize newspaper, separate rubber from cord fiber, and reduce the size of a variety of other chemical, plastic, rubber, and agricultural products.

Explosion Venting Device
Designed to protect powder and bulk solids procesing plants and personnel from explosions and flames, the IQR system contains a mesh lining that absorbs heat from flames and hot gases. The mesh acts as a heat sink that interrupts the explosion in midstream while absorbing pressure waves and dust that would normally be ejected by extremely hot and powerful vented explosions. The contained and quenched explosion from the IQR system is reduced to harmless water vapor and traces of smoke. The device can be used both indoors and outdoors whenever the impact of a vented explosion must be avoided because of space or safety issues.

Designed for high-volume dry-processing applications, the heavy-duty GravityFlowHD metal detector is compact and easy to operate, and has a high-speed reject system that minimizes product loss. The unit detects ferrous, nonferrous, and stainless-steel contaminants in bulk powdered products. Constructed of stainless steel with a user-friendly, washdown-rated control panel, it enables simplified operation and maintains a stringent inspection standard. The system also offers simple in-line testing and performance validation. Access and retrieval ports are supplied on the inlet and outlet pipes. Line personnel simply drop a standard test sample embedded with a metallic test ball into the product flow. Removable stainless-steel grids that are mounted on the accept and reject ports allow the sample to be easily recovered. The detector automatically calls for performance checks when required and issues a Test Overdue warning if the test is not promptly completed. Once the test is successfully completed, the detector reverts to normal operation.
