Sandvik QS441

2014 Sandvik QS441 Crushing Plant for sale, The QS441 is a tracked, self contained cone crusher with an on board diesel engine. Featuring the world leading CS440 Sandvik cone crusher the QS441 is capable of accepting large feed sizes and achieving exceptional throughput combined with high product quality. It is equipped with a hydroset system which provides both safety and setting adjustment functions. The automatic setting regulation system not only optimizes production, it also keeps track of liner wear, thus making it easy to plan liner changes and minimize interruptions in production. The QS441 represents the perfect combination of advanced cone crusher technology and tracked mobility. Features include -
• The chassis is constructed from heavy duty ‘I’ beam to ensure maximum
durability
• The machine is designed for ease of mobility, for rapid set up time and
transportation
• Heavy duty, hydraulically positioned feed conveyor with wear resistant
liners
• Up and over metal detector to provide ultimate cone protection from
tramp metal
• Automated variable speed feed conveyor via a level sensor to ensure
maximum production and reduction of the material
• Hydraulically driven, variable speed cooling fan for maximum efficiency
and auto reverse facility to back flush dust from the radiator
• Direct drive through a PT Tech wet clutch with ten SPC drive belts to
ensure maximum fuel efficiency and power delivery
• Fitted with four jacking legs to provide a level operating platform and
stability
• The CS440 cone has choice of three concaves and four eccentric settings
from a single bush ranging from 20mm to 36mm
• The concave and bush settings give unrivalled flexibility regarding CSS
ranges, production and material gradation
• Maximum feed size up to 450mm and capable of up to 600 tph on the
larger bush setting
• Can operate in the most hostile environments with a 50°C ambient
capability
• Superb access around the crusher for easy maintenance, especially
during liner changes
• Remote camera viewing the crushing chamber enables the operator to
set up and ensure a choke feed on the crusher from ground level
• Hydraulic driven hydraulic

The QS441 features the world-leading CS440 gyratory cone crusher from Sandvik
The “S” type can accept a feed size up to 90% larger than current standard cones allowing maximum productivity of your primary, or even run the “S” cone as a primary crusher on gravel applications.
Capable of producing large reduction ratios with minimal fines production it is ideally suited for crusher run, ballast / drainage stone or material for a tertiary crushing plant.

Unique crusher design:
-Long crushing chamber
-Very large feed opening
-Excellent reduction ratio
-Designed to be used in secondary applications
-Variable crusher speed via the engine to manipulate product gradation
-The Cone is driven through a 14” PT-Tech wet clutch (hydraulically operated)
-Oil immersed clutch plates are able to control the slippage and give a known friction and heat generation allowing for controlled engagement for a smooth start up.
-This slippage allows controlled torque limiting which protects the clutch and engine
-The PT-Tech clutch is a stand alone unit that takes the drive directly from the engine.
-Automatic proportional speed control of the feed conveyor
-Monitored by a level sensor mounted over the crushing chamber
-Ensures the cone is continually choke fed
-Camera attached to level sensor with small screen in cabinet for visual monitoring of feed material
-Display screen is located at ground level for improved operator safety
- The QS441 is powered by a Caterpillar C13 Acert Stage 3A/Tier3 or Stage 3B/Tier 4i engine developing 328kW (440hp)
