| QJ241 mobile jaw crusher  Sandvik launched the new and innovative designed QJ241 tracked jaw crusher. Purposely redesigned in order to accommodate the emissions-compliant engines in accordance with the new 2011 Stage 3B / Tier 4i Engine Legislation, Sandvik decided to also take this opportunity to redevelop and upgrade its best selling compact jaw crusher to create one of the most technologically advanced tracked crushers in the market. The upgraded model incorporates the class leading characteristics of its predecessor, the QJ240, such as the high performing powerful 1000 x 650 mm jaw with hydraulic CSS setting, reversible jaw for relieving blockages, automatic central lubrication system for reducing maintenance time, dust suppression, overband magnet and side conveyor but now includes many additional outstanding features as standard which will set it apart from the competition.One of the most advanced benefits to the customer is the addition of a raise and lower facility on the main conveyor. The conveyor can be raised and lowered for transport and will give increased clearance on the main conveyor for removal of rebar which will make it the ideal choice for recycling applications. It has also been extended to give an increased discharge height enabling enhanced stockpiling capabilities. New features: • A new hydraulic control system which will allow greater efficiency and ease of access and maintenance as all controls are located at ground level • Level sensor fitted to the jaw inlet to optimize feed rate into the crusher • Improved load control system for the feeder drive to ensure continuous, uninterrupted crushing • Speed wheel fitted to the main conveyor to stop the feeder avoiding the need to dig out a heavily loaded conveyor • Hydraulically driven cooling fan with auto reverse to back flush dust from the radiator • Enhanced fuel economy for lower cost of ownership and a reduction in emissions by upto 45% for a reduced carbon footprint • Capable of operating in the most hostile environments with a 50°C ambient temperature without any oil changes The upgraded model has been redesigned with ease of operation in mind. Operators will find the machine much more user-friendly as it has a full PLC control system with colour screen for visual data output and greater access around both sides of the powerpack for easier maintenance and service. The diesel tank and smaller hydraulic tank have inspection covers and have been relocated to the front platform of the machine for improved access and the pipe work is now fabricated from steel to give a maintenance-free sealing solution and better heat dissipation. Its heavy duty tracked chassis now driven by proportional remote control and hydraulically folding hopper enable a quick-set up time and although purpose designed for the recycling industry, the QJ241 is equally productive in quarrying applications. write your comments about the article :: © 2012 Construction News :: home page |
