Sorting line for recycling of cullet
Compound of the line
Case study
Principal types of challenges
- demanding application due to high level of abrasion of the material being processed (cullet)
- big quantity being processed (up to 10 tons/hour)
- necessity to separate both magnetic and also non-magnetic metal adulterants in a relatively small fraction (35 mm maximum).
Solution provided by SOLLAU s.r.o. company: a coherent system of separators in an antiabrasive design (vibrating feeder reinforced with abrasion-resistant sheet metal of Hardox type, fully stainless MBZ 406 N 800 magnetic drum, ECS-C 800 separator for non-ferrous metals with a thickened conveyor belt) has been delivered. The line made by our company has not only managed a demanding task in an excellent way but also the ratio ´price/performance´ is highly appraciated by the client.

This line is designed exclusively to remove metallic contaminants — both ferromagnetic and non-ferromagnetic — from crushed glass waste intended for recycling. It does not sort glass by colour or type. The input material consists of crushed glass with a fraction of up to 35 mm with a high content of metallic impurities, such as metal fragments, caps and other contaminants originating from packaging or industrial waste.
The line processes up to 10,000 kg of material per hour. It is designed for a relatively small fraction of up to 35 mm, capturing ferromagnetic particles from a size of 0.5 mm. The high capacity combined with the small fraction size and extreme abrasiveness of the material placed completely different design requirements compared to lines for plastics.
Crushed glass is one of the most abrasive materials in recycling — standard structural materials would wear out quickly in contact with it. For this reason, the vibratory feeder is reinforced with Hardox wear-resistant plates, the MBZ magnetic drum is made entirely of stainless steel, and the ECS separator's conveyor belt is reinforced. Every contact surface with the material is dimensioned for operation in these conditions.
The eddy current separator ECS-C 800 with a concentrically mounted rotor for a belt width of 800 mm separates non-ferromagnetic metals — aluminium, copper and other non-ferrous metals — from the stream of crushed glass. It operates on the principle of eddy currents, which expel non-magnetic metal particles from the material flow. The reinforced conveyor belt is a design adaptation for extremely abrasive glass, which would quickly damage a standard belt.
The magnetic drum cover shell comes into direct contact with the abrasive material and gradually wears out during intensive operation. The design solution allows it to be replaced without the need to dismantle the entire drum or replace the magnetic core — significantly reducing maintenance costs and shortening equipment downtime. The magnetic core itself is covered by a 5-year warranty.
We design and manufacture every separation line to order according to the specific type of material, its granulometry and the required capacity. We also implement lines for sorting municipal waste, plastic waste and other materials — we always adapt the equipment configuration to the specific application.
The delivery covers the entire process — from site survey, design and custom manufacturing through assembly, commissioning and operator training to authorised service throughout the lifetime of the equipment. We provide a 5-year warranty on the magnetic core of the MBZ separation drum. Before placing an order, we offer free testing of your material with a guaranteed turnaround time of three days.
