Toothed roller crusher HRX 800

stationarycompactwet type

Overview
The HRX 800 sizer delivers high capacity in a compact footprint for hard rock, ore and overburden applications. Designed to accept large lump sizes, it extends the use of sizers into locations where conventional crushers cannot be installed.

• Easy maintenance
• High capacity
• Compact design

Features and benefits

• High capacity - Reduces the number of crushing or dump stations required by handling very large lump sizes and increasing crushing ratios.
• Reduce costs - Small machine envelope enables installation in mobile or underground sites where other crushers would not fit, lowering installation costs.
• Ability to crush wet, sticky materials - Frame cleaners scrape off material accumulation; effective with clay, marl and tunnel spoil.
• Efficient and cost-effective - Energy-efficient helical gear reducers, robust power transmission, automatic lubrication, extended-life picks and smart-machine monitoring for predictive maintenance.
• Minimizes water and dust ingression - Outboard bearing design with custom seals reduces ingress where water spray is used for dust suppression or washing.
• Variety of pick designs - Multiple pick options for hard, abrasive and sticky applications, developed from experience with feeder breakers and continuous miners.
• Replaceable picks - Renew-able picks on sizer shafts improve lifecycle compared with disposable solutions.
• Control product size - Adjustable removable breaker bars and pick selection allow control of product size to minimize issues at chutes, transfer points and conveyors.
• Instrumentation to increase reliability - Bearing temperature and vibration monitoring plus locked-rotor detection alarms help protect the machine from tramp metal and reduce downtime.
