Satrind has recently supplied a solution suitable to handle industrial waste (such as drums, bins, contaminated rags, oil filters) to produce alternative fuel for a cement kiln.
The customer is a large Turkish company, specialised in waste collection and treatment, that has entered in a joint-venture agreement with a Turkish cement company, which produces alternative fuel from waste.

To satisfy the final customer’s requirements the plant must guarantee the required output material size to be burned into the kiln.
The plant has a capacity of 6tph and is composed by a primary shredding stage with 2R20/220, Satrind’s two-shaft shredder, and by a secondary shredding stage with 3R15/320, Satrind’s three-shaft shredder with selection screen.

The material to be treated is loaded by a crane into the feeding hopper of the first shredder fitted with an hydraulic ram to press the material on the blades. The output material falls into a screw conveyor designed to separate the liquid from the solid. Solid material is then discharged onto a conveyor belt with a magnetic separator to extract the metal parts. Next, the waste is processed by the 3R15/320 three-shaft shredder with selection screen to obtain uniform output material size (40mm x 40mm). Another screw conveyor and conveyor belt with magnetic separator are positioned after the second shredder and can discharge directly into a pit.
The shredded material is transported from the pit to a storage centre by a conveyor belt where the material, is stocked ready to be burned as alternative fuel into the kilns.

There are a lot of reasons for identifying products in processing and logistics.

Traditionally, most markings have been used for product control and tracking. Introducing manufacture standards according to DIN ISO 9000 required new methods regarding quality management and identification. But these are not the only reasons to advance permanent marking. There is a growing demand for unique and durable product identification to secure property rights, to protect plagiarism or to provide a basis for a possibly occurring product liability.

The decision on which technique is finally used mainly depends on whether the marking requires to be durable or not.

Whilst marking techniques like label printing, inkjet coding or tampon printing are known as temporary identification methods, laser marking becomes more and more established among the durable, industrial product identification methods.

Laser marking provides fast, precise markings with excellent reading results on a wide range of materials and without any mechanical action. The highly focused, invisible infrared laser light generates a great energy transfer that causes physical and chemical interactions at the work piece surface. Reaction can be strong enough to cause the evaporisation of the material and thus an engraving or cut.

The lasers enable to mark fonts, graphics and standardized codes in the intensity needed. Markings can be realized on materials that tend to change color in oxidation without damaging the surface. This feature is used for marking products with high demands on surface, mainly for marking stainless steels in the field of biomechanics and the manufacture of medical instruments.

One other significant advantage is that laser marking does work without consumables. This avoids cost- intensive downtimes and related to this production failures. Laser systems are always integrated into production processes with large throughput and high demand on availability.

cab is using diode pumped Ytterbium Fiber Laser systems FL10 and FL20. Highest beam quality and pulse peak power allow markings on a wide range of materials like steel, aluminium, precious metals and plastics.
