    A new line for the production of 7,000 m2/day monoporous ceramic tile and the extension of the existing one : FAIENCERIES ALGERIENNES ceramics confirms once again the validity of WELKO plants and technology.
    The new investment will allow a production increase of 10,000 m2/day by the installation of a very new roller kiln, WFR series, 2,830 mm wide and 126 m. long, the extension of an existing kiln, four 2,800 t. presses of the latest WK series with relevant dryers, mills for the preparation of slip, a spray-dryer, a parking system and relevant glazing lines.
    The technologic contribution that WELKO will put at disposal of the ceramic factory will be substantial and it will allow a considerable evolution in both technical and quality field of the product.
    The plant is starting to run by the end of this year.
    JALARAM (India) has chosen WELKO to update its plants.
    Among the major producers in India, Jalaram has recently widened its productive capacity and typology by installing a WK2 press of 4600 t. and 2,250 mm wide, a kiln of the new WFR series and 138 m. long, a modern parking and a special line of glazing and salt application for the production of vitrified ceramic stoneware.
    The plant, presently on a steady state, produces 6,000 m2/day of big sizes, once again pointing out how the use of WELKO technology and its new WK2 two-piston presses is a guarantee of quality and reliability in the long run.
    CERPA SL, a primary firm in the area of Castellon (Spain), has re-confirmed its trust in WELKO : the present production lines made by WELKO shall be shortly flanked by a very modern roller kiln for the production of single-fired and vitrified stoneware tiles in the different typologies and sizes.
    The kiln, 105 m. long and 2,830 mm wide, shall be equipped with the most modern control systems of temperature and motion; thanks to the recent innovations set up by the technical and product development Welko staff, the machine, already belonging to the latest kiln generation, will represent a further evolution and will be equipped with solutions able to increase versatility, efficiency and reliability.
  • 01/03/2005 - NEW HORIZONTAL 5-LEVEL DRYER:
    In its modernization program of thermic machines, WELKO has recently set up and tested a very modern thermic machine to dry pressed and extruded ceramic products in big thicknesses.
    The 5-roller-level in motion Dryer is featured by an excellent flexibility combined with a perfect control not only of the temperature but of the moisture inside the channels as well.
    The motion systems of the five levels are independent so as to change the working cycles of formats, thicknesses and sizes.
    The dryer is made up of various flanked modules (each module is 2100 mm long); each one of these modules is equipped with the following:
    N° 1 re-circulation fan
    N° 1 burner with automatic adjustment
    N° 1 adjustment thermocouple
    N° 1 series of piping for air inlet over and under the tiles
    N° 1 exhausted air suction system
    N° 1 dry air restoration.
    The last modules are provided with a cooling and heating system, allowing to control and keep the temperature of the material constant both in the case of empty spaces and of stop of the unloading line.
    The thermic capacity of the burners installed in each module ranges from 75,000 to 300,000 kCal/each according to cycles and dryer width, whereas the power of re-circulation fans ranges from 5.5 to 11.0 kW per element.
    The motion system is of the same kind as the kiln : geared, without any need for lubrication, for a traction able to handle important thicknesses and weights.
    The new and very modern WELKO plant for the production of 7,000 m2/day of vitrified stoneware ceramic tile is in course of installation at MARAZZI works in Malino, Russia.
    The plant avails itself of the latest Picasso technology, which will allow MARAZZI to assail the Russian market by a variety of products, up-to-date in the field.
    The plant is made up of : a continuous mill of 65000 l., two spray-dryers, a system of movable silos, two WK2 presses of 4600 t. in width 2250 mm., two fully equipped PICASSO Systems, two 3-channel dryers of 18.9 m., two glazing lines, a storage system, a very modern roller kiln of 113 m. and an automatic sorting department with palletizer.
    At the same time, the laboratory of TECNOGRAFICA-WELKO in Castellarano (Reggio Emilia) has already set up the development of the new products which will be the basis of PICASSO production : WELKO reveals itself to be the ideal partner being able to accompany the customer towards the best solutions of plant engineering, technology and production.
    PICASSO has been started up at Ceramica Ariana, ABK Group, in Castellarano.
    The system, made up of one WK2 2-piston 3500 t. press in width 2250 mm and one PICASSO equipped with three robots and a technologic tower for preparation and feeding of powders, has become operative.
    The first products in different sizes, including 500 x 500 mm and 600 x 600 mm, had already been introduced with a remarkable success at Rimini 2004 fair and have created the starting basis for the development of other winning product typologies on the market.
    By this investment, the Group intends to differ thanks to the huge possibilities and productive flexibility that the system permits.
    The development of the products takes constantly place in cooperation with TECNOGRAFICA WELKO, the company that has been created on purpose to give the technologic graphic support to the ceramic factories which want to differ with new graphic and aesthetic effects.
    On January 21st, 2005, new products obtained by PICASSO system have been introduced in Castellarano (RE).
    Inside the splendid castle in Castellarano, TECNOGRAFICA WELKO has presented a series of new products obtained thanks to the experience of TECNOGRAFICA and the technology of PICASSO system, worked out and set up by WELKO.
    The products have been obtained at the laboratories of Tecnografica Welko in Castellarano, where a fully-equipped PICASSO system, a WK2 press, 2-piston, 2250 mm wide, 3500 t., a single-channel dryer and a glazing line permit to develop new graphic and technical effects.
    Great has been the interest by the manufacturers and traders in the field, increasingly addressed to the search of a technology which allows, easily and with great flexibility, to get new typologies that are able to raise the product quality and to identify the producer in a market where it is more and more difficult to distinguish oneself and create one’s own image.
    Marbles, granites, natural stones, in different sizes, have been presented beside natural products, once again exalting WELKO’s and TECNOGRAFICA’s ability to acquire the clients’ trust.
  • 10/01/2005 - WELKO PRESSES ALSO POTS & PANS:
    In January 2005 successfully started production, at the Bialetti workshop - Rondine di Coccaglio (Brescia) - the first 5200 ton press in the world manufacturing aluminium pots & pans. The machine, with its 6 m structure height, represents a further evolution of the range WK and WK2, the already well tested press with single or double pistons to manufacture ceramic tiles. The presses WK and WK2 come in different models, from 1500 to 7200 tons with a free clearance between posts up to 2500 mm.
    Latest achievement, after the 6300 ton. and 7200 ton/2500 mm free clearance, the 3500 ton/2500 mm free clearance provides maximum productivity where high tonnage is not requested.
    Once more Welko confirms its capacity and willingness to provide personal customized service to its clients.
