Mogensen Sizer technology for processing sand for renders and mortar rendersThe variety of premixes available on the market
for the preparation of concrete, mortar, render,
adhesives, coating compounds and related products
has steadily increased in recent years and has now
reached almost immense proportions. As a result,
the process engineering for preparation of the necessary
sand mixes must meet extreme requirements in certain
applications. The classical Mogensen Sizer technology,
which enables multiple separations of different
basic materials in a minimum of space is successfully
used for modern sand processing in the futuristic
mixing tower at Saint-Gobain Weber-Beamix in Eindhoven. |

Glass RecyclingGlass is used widely as a high quality, inert packaging
material. A large percentage of the raw materials
used consists of recycled glass. This paper describes
the development and adaption of sorting and screening
systems to meet the ever growing requirements. |

Optical Sorting of Quartz Gravel to Reduce the Iron ContentSilicon producers need coarse-grained quartz with
a minimum content of metallic impurities for optimal
charging of their smelters. This report describes
how the automatic sorting of quartz gravel in the
size range 30–100 mm by colour and brightness signifi
cantly lowered the content of impurities. |

Coarse Separation of Moist and Impure Raw MaterialsThe coarse separation of moist and impure raw materials,
even at coarse cut-points, regularly causes problems
such as screen clogging or blinding caused by extreme
material bed formation. At a quarry in Puerto Rico,
a Mogensen Vibratory Bar Sizer is used to screen
off the unusable waste material. Thanks to its special
design, based on vibrating bars fixed at one end,
this sizer operates without clogging and without
any reduction in capacity even in changing weather
conditions. |

Glass Recycling with Mogensen Sorting and Screening SystemsGlass is used widely as a high-quality, inert packaging
material. A large percentage of the raw materials
used in glass production consists of recycled glass.
The recycling quota for refuse glass exceeds 90
%. To achieve such a high quota, a sophisticated
sorting system combined with efficient equipment
for pre-sizing is essential. This paper describes
the development and adaption of Mogensen sorting
and screening systems to meet the ever growing requirements
of established and new applications, particularly
in the recycling of refuse glass. |

Fine Screening of Sanding Dust Machining stages such as sawing, cutting, or sanding
in the production of derived timber materials result
in considerable quantities of fine wood dust. Besides
fine particles, this dust contains fibrous components
and chips. For effective thermal utilization, the
dust must be sized on a screen prior to burning.
At the Eiweiler facility of Glunz AG, a screening
system centring around a Mogensen Sizer 2000 has
been in operation for some time now. The direct
excitation of the screen by means of rapping bars
ensures blindingfree screening despite the difficult-to-screen
feed material. |

Classifying Extremely Difficult-to-Screen Lava Stone The high inherent moisture of volcanic cinder
Ð particularly in the fines range Ð has so far hindered
optimum classification of this material. At the
Andernacher Lavakontor Works at Nickenich, which
belongs to the German company Rheinischen Provinzial-Basalt-
und Lavawerke GmbH (RPBL), a new fines screening
plant incorporating the innovative Mogensen Sizer
2000 has now been operating for some time in the
preparation facility. In combination with screen
deck heating, alternately rapping bars prevent pegging
and blinding of the screening surface Ð even when
processing feed materials with particularly high
moisture contents, to ensure successful classification. |

Optoelectronic Separation in Feldspar Processing at Maffei SardaFor feldspar processing at its Orani plant in Sardinia,
Maffei Sarda uses two MikroSort optoelectronic separating
devices. Feldspar impurities of unacceptable colour
are removed in order to obtain the whiteness demanded
by the ceramics industry. The upgrading of the separating
devices with a new colour tracking system has further
improved their operating performance. |

The Use of a Mogensen Sizer and MikroSort Optoelectronic System in Aluminium ProductionDuring the two-stage process for the production
of aluminium from bauxite, sizing and separation
equipment is used in the different process stages.
This paper takes the German aluminium producer Corus
in Voerde as a case study to describe the successful
application of a Mogensen Sizer and MikroSort optoelectronic
system. |

The 4th Generation Mogensen SizersThe reliability and availability for operation
of a screening machine depend crucially on the use
of proven components. Consequently, the standardization
of individual assembly groups has been established
corporate philosophy at Mogensen since its founding
in 1968 to the present day. Special, tailored solutions
in dynamic mechanical engineering systems, however,
are always the product of a go-it-alone design approach
and as such are associated with a high risk of machine
breakdown. The new, redesigned version of the Mogensen
SC Long Deck Sizer is now replacing the SL Sizer
marketed over the last ten years. The operation
of this screening machine and the Sizer operating
principle have not been changed. At the same time,
a new type of sizer, the SG, has been developed,
which with its circular-motion vibration is particularly
suitable for sizing difficult-to-screen products. |
