of sieving and our approach to it

How can I find the correct spare part for an MLT Cuccolini vibrating sieve?

To identify the correct spare part, it is essential to provide the machine serial number. Every MLT Cuccolini vibrating sieve is configured according to the specific application, the material being processed, the installation context, and any applicable industry standards. The serial number allows us to trace the machine’s original configuration and ensure the supply of perfectly compatible components, helping to maintain performance, reliability, and long-term service life.

A compatible spare part may fit the machine dimensionally, but it does not necessarily guarantee the same performance, durability, or quality standards as an original component. Furthermore, the use of non-original parts may affect machine performance and should be carefully evaluated with regard to safety, certification, and warranty requirements.

To provide an accurate quotation, we require the machine serial number, the material being processed, the process throughput, and the mesh opening of the installed sieving mesh(es). Photos and videos of the installation are also highly valuable, as they allow MLT Cuccolini’s technical team to assess the actual operating conditions and recommend the most suitable solution.

MLT Cuccolini can evaluate the performance of vibrating sieve manufactured by other companies and offers sieve mesh refurbishment services for most circular sieves available on the market. Service procedures and costs are assessed on a case-by-case basis according to the specific application requirements.

Proper preventive maintenance includes regular inspection of the sieving meshes, checking the vibrating components, tightening structural fasteners, cleaning the machine, and replacing worn parts. Routine maintenance helps maintain high process performance while reducing the risk of unexpected downtime. Maintenance spares sets are available on request.

The service life of a sieving mesh depends on several factors, including the material being processed, product abrasiveness, throughput, operating conditions, and the type of mesh used. Correct machine configuration, together with regular maintenance of both the sieve and the mesh support rings, can significantly extend mesh life.

A sieving mesh should be replaced when signs of wear, deformation, damage, or a gradual reduction in separation efficiency become evident. Regular inspections help prevent product quality issues and minimize the risk of unplanned production downtime.

Sieving efficiency can be improved by optimizing several factors, including mesh selection, sieve configuration, mesh cleaning systems, and product feeding methods. A technical process analysis allows the most effective solutions to be identified in order to increase productivity and improve separation quality.

Mesh blinding can result from the characteristics of the processed material, product moisture, irregular particle shapes, or a suboptimal machine configuration. The use of deblending systems such as rubber balls, multifrequency or ultrasonic technology, or other dedicated solutions can help maintain high screening efficiency.

In many cases, it is possible to modify or upgrade an existing machine to meet new production requirements. However, every modification must be carefully evaluated to ensure that machine performance, safety requirements, and compliance with applicable regulations are maintained.

Yes. MLT Cuccolini provides sieving test services to evaluate the actual behaviour of the product and identify the most effective machine configuration. Tests can be carried out at our facilities or, in specific cases, directly at the customer’s plant.

MLT Cuccolini designs and manufactures solutions that comply with ATEX Directives for applications involving potentially explosive atmospheres. To identify the most suitable solution, it is important to define the hazardous area classification and the applicable regulatory requirements from the earliest stages of the project, together with all application details.

Yes. MLT Cuccolini’s Aftermarket Division provides specialized technical support both remotely and on-site. Services include maintenance, troubleshooting, process optimization, the supply of original spare parts, training, and technical consulting.

Delivery times depend on the required machine configuration and component availability. Standard spare parts and consumables are generally available with short lead times, while complete machines require dedicated production scheduling. For many standardized configurations, production can typically be completed within 3–4 weeks from order confirmation.

Yes. In addition to vibrating sieves, MLT Cuccolini supplies complete turnkey sieving systems, including product feeding, process handling, and dedicated solutions for special applications. For specific process requirements, controlled inerting systems can also be integrated using proprietary software for the management of gases such as nitrogen or argon.
