In the stone and earth industry, raw materials are processed efficiently and gently by crushing, screening and washing. These steps ensure optimum material quality and tailor the end product to the respective requirements.

Simatec elliptical screening machines are characterized above all by their high screening quality. Their fields of application are wet and dry screening. The separation cuts are preferably in the fine or medium grain segment.

• independently adjustable parameters
• mechanically synchronized exciter shafts
• sharper separation cut / higher screening quality
• approx. 20 - 30 % higher screening capacity with the same
• screening area compared to other vibrating systems
• simpler maintenance and cleaning work
• lower installation height

Simatec linear screening machines are primarily found in post-washing and dewatering processes. For the classical dewatering of the product, these are used as single deck screening machines, with rising deck, as well as rear wall dewatering windows. Side drainage windows are optionally available as an additional drainage stage.

As an additional post-wash, after a first washing stage, an efficient spray is installed in the task area.

Two-deck screening machines are used for gravel or mixed gravel and sand dewatering. The upper deck is used, among other things, as a protective deck or for rough grain classification.

Simatec circular vibratory screens are often installed as pre-separators or relief screens at the beginning of the engineering process. The circular motion coupled with the inclination gives the material the necessary impulse and ensures that the risk of plugging remains low.

However, Simatec circular vibratory screens are also used in classical screening for classifying medium to rough grained bulk materials up to a size of approx. 150 mm.

They are mainly used in dry screening and still occasionally in wet screening. The optimum screening angle, which is indispensable for the transport of the material, is between 10° and 20°.
