Sandvik QA335 Tracked 3-Deck Screening Plant

The Sandvik QA335 is a self-propelled, fully tracked triple-deck screening plant designed to sort crushed aggregate and sand into three product fractions simultaneously, enabling a complete crushing and screening circuit without a separate fixed screen structure. Driven by a CAT C7.1 engine producing 168 kW (225 hp), the QA335 mounts a 5.5 × 1.5 m triple-deck inclined screen that delivers material separation across three product belts plus an oversize return or stockpile conveyor. The plant's compact tracked footprint and four-way splitting capability make it the mobile screening complement to the QJ341 jaw crusher and QH441 cone crusher, creating a complete three-machine mobile crushing and screening train capable of producing three specification-sized products from raw quarry feed.

The QA335's screening box uses triple-shaft exciter mechanism to generate a high-energy circular motion across the full screen deck width, achieving high separation efficiency in both dry and slightly damp aggregate — a key consideration in Saudi Arabia's coastal quarry sites near Jizan, Yanbu, and Jeddah where coastal humidity can add moisture to aggregate stockpiles. The screen media selection covers wire mesh, polyurethane panels, and rubber screen modules to match each Saudi aggregate specification and rock type, and the hydraulic tensioning system allows screen panel changes to be completed rapidly during planned production stops. Side tensioning rails lock the panels securely during the intense vibration of high-throughput screening.

Saudi Arabia's expanding aggregate market is driven not only by volume demand for crushed stone but by specification compliance requirements that have tightened considerably since SASO updated its aggregate standard in line with international concrete and asphalt norms. Producing three simultaneously specification-compliant fractions — typically 0–5 mm fines, 10 mm single-size, and 20 mm single-size, with oversize returning to the tertiary cone — from a single tracked screen dramatically reduces the number of stockpile handling and re-screening steps at Saudi quarry sites. Saudi Readymix Concrete Company, LafargeHolcim Saudi Arabia, and the independent quarry operators supplying Riyadh's Ring Road construction require consistent aggregate grading curves that the QA335's triple-deck precision delivers.

Razz Middle East provides QA335 systems for sale and hire across Saudi Arabia, with technical support covering screen media selection and sizing, vibration analysis, and deck angle optimisation for the specific aggregate gradations required by each Saudi customer's concrete or asphalt specification. Our engineers advise on complete mobile crushing and screening train configurations combining the QJ341 jaw, QH441 or QH332 cone, and QA335 screen to meet production targets and product specifications for each Saudi project application.
