Whereas in 2005 there were more than 80 active brick plants on the Algerian market (total annual production up to 7 mill. t), by 2017 there were already active 180 plants with a production of over 25 mill. t/year. Some of these plants that are in operation today have been designed for a clay brick production capacity up to 700 000 t per year. In addition, there are as many as 30 plants which are either still at the planning stage or under construction. More than half of these new plants have been supplied and installed by Talleres Felipe Verdés S.A. with the support of its subsidiary Verdés Al-Djazair, which provides after-sales service and supplies duly imported spare parts in the local currency, making the Spanish brand one of the leading providers of preparation and moulding production lines, both for the traditional wet and dry methods of production.
EURL Moulin Ouled
Talleres Felipe Verdés S.A. has recently set up a new plant, EURL Moulin Ouled Maalah in Mostaganem, with a nominal capacity of 270 000 t/year, or 794 t/day, based on a rate of 91 t/h for the preparation line with two working shifts, and 69 t/h for the moulding line based on three working shifts.
The preparation line has been designed for the semi-wet method, with one of the first pre-grinding installations in Algeria. This consists of a 118 DT primary crusher with a capacity of 150 t/h followed by open air storage with a storage volume of approximately 12 000 m³.
The clay is received by a box feeder that supplies a secondary grinder: a disintegrator model 127C, Ø 1 000 x 1 000 mm, with a capacity of 100 t/h. After that the clay is conveyed to a third grinder, a next-generation Optima 1 000B roller mill with a 3.5 to 4 mm gap. The clay and sand are then discharged into a 046 C double-shaft mixer to be either mixed or delivered to the storage facility.
A DRAVH 14.7/65/1200 reclaimer model collects the homogenized clay, which is then conveyed by means of a box feeder to the shaping area, to a second 046 C double-shaft mixer, and after that to an Optima 1200B roller mill with a gap from 1.5 to 1.2 mm.
The Magna 675/50 extruder with conical augers, in 26 % to 28 % chromium alloy, has a production capacity of 69 t/h, and works at a pressure of 20 to 22 bar, and with approximately 20 % clay body moisture content, which facilitates operation, saves time and of course the cost of drying.
The EURL Moulin Ouled Maalah has been in operation since the beginning of December 2017.
Over the next few months, other plants built by Talleres Felipe Verdés S.A. are set to be commissioned:
A plant in Laghouat (Briqueterie Moderne Amouri Laghouat, or BMAL for short) with a capacity of 700 000 t per year
As part of an upgrade of a plant in Djelfa (Progec MAC II), a second hammer mill, an automated storage facility and a second preparation line are being installed to double the current production from 140 000 t to 280 000 t per year
A new plant on the west coast of the country (Briqueterie Tamazoura), with a capacity of 280 000 t per year
Besides all this recent productive activity in the Algerian heavy clay market, Verdés also supplied several machines to, for example, France, Belgium, Malaysia, Saudi Arabia, the Russian Federation, and Colombia in 2017.
