DMN : Dust Lock is ATEX Approved & Flameproof

The Netherlands -- The DL dust airlock from DMN-Westinghouse has been ATEX approved and optional available flameproof up to 3 bar. The ATEX approval is awarded for protective system / equipment up to 3 bar, Dust class 2 marking Ex II D / 1D/2GD, as well as for equipment marking Ex II 1D/2GD.

The DMN-Westinghouse DL (Dust Lock) is of a dedicated design for filter applications and is conforming to ATEX Directive 94/9/EC. The standard valve is pressure shock resistant up to 10 bar g pressure. Recently the DL was also tested and approved flameproof up to 3 bar. Both the standard version and the ATEX 3 bar flameproof version can be delivered ex stock.

The universal flanges on both sides of the valve are suitable for both round and square counter flanges and are drilled to PN 10. The angle of the inlet down to the rotor has been kept as steep as possible, to reduce the chance of bridging. The outlet from the valve is round, so that you can discharge into either a round or square connection.

The DL valve has a very large inlet and a direct drive, providing ample torque to drive the rotor, which has replaceable and adjustable polyurethane blades. An optional steel fixed bladed rotor is also available.

The standard drive is a Nord helical geared motor, type SK01-F-71L/4, 0.37 kW, IP 55, isol. F, giving 27 rpm at 50 Hz and 32.4 rpm at 60 Hz. Suitable for 230/400V 50 Hz and 278/480V 60 Hz. The standard model is suitable for handling products up to a temperature of 70 °C and a maximum pressure differential of 0.5 bar.

Uzwil, Switzerland -- The Buhler Technology Group has been awarded a contract from Saudi Arabia for the supply of a large grain mill. The total worth of this turnkey order based on state-of-the-art grain milling technology is CHF 40 million.

The Grain Silo Flour Mills Organization (GSFMO) has awarded the Buhler Group a contract for the supply of a large-scale installation. The new grain milling facility will be built near Al Madinah, one of the pilgrim sites in Saudi Arabia. The contract worth a total of CHF 40 million includes – beside the buildings – the entire electrical installation, mechanical equipment, and control system plus installation and start-up.

The building construction worth CHF 10 million has been entrusted to an outside subcontractor, whereas all the other items of the contract will be supplied by Buhler itself. The milling installation will have a processing capacity of 600 metric tons a day. Other plant sections include a grain storage silo, a precleaning system, a finished products storage system, three bagging lines, and a product loadout section. The plant is scheduled to start operation within about two years. This is a great challenge for a turnkey project.

The Saudi population is growing at an annual rate of about four percent, and Saudi Arabia is covering its food supply requirements by growing high-quality wheat (two million metric tons per year). Large fields of wheat are under cultivation in the middle of the desert. The necessary water is in some cases pumped from a depth of several hundred meters onto the fields to irrigate the crops.

The grinding process also requires large volumes of water to ensure that the grain and later on the flour will not dry out. An Airwash system specially developed for hot regions humidifies the process air. The offices and building sections housing the electrical equipment must be air-conditioned in view of the high outdoor temperatures, which may reach 50 degrees Celsius. On the other hand, the installation work is normally carried out at these high temperatures.

Buhler is a global technology group and system partner for the supply of plant, equipment, and process expertise in the fields of Food Processing, Chemical Engineering, and Die Casting, with a global payroll of over 6000 and annual sales (turnover) of 1.5 billion Swiss francs.

Mr. Bundalli wants coating for screw conveyors:

We are working on a project where we will have collection screws under our proprietary "Moving Hole" feeder to convey poultry litter fuel. Abrasion resistant coatings on the screw is specified. "Unideg" lining compound made in the UK is suggested.

We would like feedback from anyone with first hand experience or expertise in abrasion resistant coatings for screws. An alternative coating I have come across is Belzona - again made in the UK.

We have tested wall friction for this coating, which is very low against biomass. According to product literature, this coating provides good erosion/corrosion protection. Anyone with experience or expertise on this coating?

Mr. Fradd wants to redesign his storage bins:

BACKGROUND: We have 2 cylindrical storage bins each of 250 t capacity that feeds raw zinc oxide powder out through the bottom cone which holds up at times & includes lumps, at times can be a moist rubble type product (reclaimed and "dried" from thickener tanks and sumps).

The online process raw fume product feeds into one of either bins 24/7 and is about 85 degrees C. Fume mix is also fed into the same bin as mentioned above and can include EAF fines, boiler ash etc. Compressed air ( and probably wet) can be blown in at right angles on the bin side to aid in removing hang ups.

MORE RECENT: We've always had bin activators that oscillate the cone on the bin discharge to run fume into a VFI controlled discharge screw (signal back by a weighfeeder belt) and due to all the recent "poor bin flows" we have been experiencing we are about to retro fit, redesign, do away with but fix the problem.

We air sparge from a door at the bottom too but this pressurizes the bin, flood feeds, buries weighfeeder etc.

Got any ideas how to modernize? I've heard about live bottoms, mass flow bins in part but are there options (more modern) that may even do away with the bins altogether?  Sorry for the long spiel.
