2026 PROMAC Screening Equipment QA442

The Sandvik QA442 is the latest evolution of the Sandvik QA Series products and Sandvik Doublescreen technology. The QA442 has been developed with sustainability, productivity, and lower cost of ownership in mind. A high performing processing solution, ideal for producing massive volumes of high specification products for the mineral, aggregate and recycling industries.

The QA442 features Sandvik Doublescreen technology, it utilizes two high velocity two-deck inline screens with equal size screen decks, each providing 9 m3 / 100 sq. ft of screening area. The primary screen performs as a fines extractor, whilst the secondary screen performs as a grader. Two processes combined on one plant, offering exceptional flexibility, excellent separation, accurate grading and massive throughput.

Both primary and secondary screening angles can be adjusted independently, leading to greater material control, greater adjustability, increased accuracy and higher screening efficiencies. Each screen deck features end tension screen media using Sandvik’s unique mesh tensioning system. This means faster screen mesh tensioning and removal when you need uptime.

Features may include:

• • Hybrid “e” drive lets you choose your most economical and efficient energy source

• • World class Doublescreen design with independent screen angle adjustment for greater material control, increased accuracy, higher screening efficiencies and hydraulic screen separation for faster screen media changes

• • Featuring two 2-deck inline screens with equal size decks, each providing 9 m3 / 100 sq. ft of screening area

• • Choice of screen media to suit a range of applications including Sandvik WX media offering up to 10x longer wear life

• • Lower environmental impact due to lower running speeds, reduced fuel consumption, less operating noise and lower emissions

• • User friendly PLC control system with sequential start-stop for speed and ease of set-up
