Features

A major aggregate producer in Ireland, Roadstone Provinces Ltd employs one of its five Lokotrack® LT1415™ impact crusher plants at the Bunratty Quarry. The LT1415 offers the largest feed opening in its weight class, which is especially benefical for high-performance quarry operation. Efficient scalping, high crushing power, robust construction and full on-site mobility make the LT1415 the world's favourite high-performing impact crusher. The LT1415's typical production equals 600 mtph (660 stph) of 0–120 mm (0–4 23⁄32”) primary crushed limestone.

The LT1415 is equipped with a pan feeder and vibrating grizzly. For scalping sticky feed materials, a roller grizzly is also available. The LT1415 can be equipped with a two-deck 5.6 m2 (6.7 yd2) screen with the possibility of recirculating oversize material from one or two decks.

The Lokotrack LT1415 power transmission is a combination of direct, hydraulic and electric drives. The Lokotrack® LT1415E™ with electric power transmission offers the possibility to use electric power either from the external grid, or generated by the on-board diesel generating set.

 

Benefits

  • High production
  • Full mobility
  • Proven and reliable

Process overview

LT1415 is used in primary crushing stage. It is typically loaded with an excavator or wheel loader. Vibrating feeder transfers the oversize blocks to the impactor which reduces them to the desired size. Undersize material drops through the grizzly directly on to the main conveyor which discharges the primary product further in the crushing process. Optionally fine gradations can be directed to the side conveyor. Screen module in open or closed circuit is also available for the process.


 



How it works

Lokotrack LT1415 is track mounted fully mobile impactor plant. It can be moved flexibly in different locations at the site. The Lokotrack LT1415 power transmission is a combination of direct, hydraulic and electric drives. The Lokotrack® LT1415E™ with electric power transmission offers the possibility to use electric power either from the external grid, or generated by the on-board diesel generating set.

Lokotrack LT1415 is equipped with a pan feeder and vibrating grizzly scalper. For sticky material a roller grizzly is also available.  capable of handling the stickiest feed materials. Additionally, the LT1415 can be equipped with the optional highly efficient two-deck screen and product conveyors. This enables production of one or two calibrated end products. When equipped with the circulation conveyor, the screen oversize fractions can be returned to the crusher.
