Gypsum industry news

Mexico: Gabriel Pérez Kohler has been appointed as the general manager of Knauf Mexico. Kohler is a graduate of the University of Texas and was previously the general manager at Strategic Media. He holds 18 years of experience in the construction industry in Mexico, including a number of jobs and projects for business growth in the country of Black & Decker, Sherwin Williams and USG amongst other companies.

Colombia/Mexico: Mexican gypsum wallboard producers including USG Mexico and Abasteco Maxima (Abamax) will have to pay anti-dumping duties on imports to Colombia following an investigation by the Committee on Trade Practices. USG Mexico will be required to pay a 25% tariff, Abamax will have to a pay a 7.15% tariff and all other importers will face a 42.86% tariff, according to the Sentido Común website. The government will implement the tariffs over the next two years and will then reassess the situation.

US: Sensortech Systems is looking for client companies to run extended trials of its new Kiln Jam Detector KJD-7000. Part of the trial will be to test the functionality of the sensor and, over a period of some months, check reliability and stability. Another part is to receive input from users as to what features need to be incorporated, particularly in the software design.

The company says that its new radio frequency (RF) gypsum wallboard jam detector product offers a saving compared to previous sensors. The RF sensor requires no maintenance and is unaffected by siloxane build-up or other debris. The Kiln Jam Detector KJD-7000 uses a custom-designed coaxial cable able to withstand the high operating temperatures.

The sensor itself follows the design of open-frame planar sensors used for moisture measurement. The outer frame is formed from 16ga stainless steel; ceramic insulators isolate a stainless-steel centre electrode to which the high temperature cable is attached. The electronics unit is located outside the dryer at each deck level. An on-board 32-bit ARM-Based micro-controller processes signals from up to three sensors and networks via RS-485 to a dedicated programmable logic controller (PLC).

The system software is set to trigger an alarm when either no product is detected over the sensor for a pre-defined time interval, a blockage upstream, or if a failure to detect gaps between boards over a pre-defined time is recognised. All sensors in an array are node addressable on an RS-485 network. If an anomaly occurs at any sensor, the exact position will be known including which deck and its position on the deck (left, right, centre).

Sensortech will be displaying its new kiln sensor at the Global Gypsum Conference & Exhibition taking place in Krakow, Poland on 25 – 26 October 2017.

Oman: Hilal bin Mohammed al-Busaidi, the chief executive officer (CEO) of the Public Authority for Mining (PAM), predicts that Oman is set to become the largest exporter of gypsum by the end of 2017. Its gypsum exports are expected to exceed 10Mt in 2018 from 4.6Mt in 2016, according to the Oman News Agency. So far the country has exported 6.1Mt in the first nine months of 2017.

PAM says that Oman has 1Bnt of reserves of gypsum. These are concentrated in the southern part of the country and in some northern regions notably in Al Shuwaimiyah, Thumrait, Sadah, Ghaba and Buraimi. The principal export markets for the product are India, Japan, Taiwan, Indonesia, Vietnam and Bangladesh.
