Detailed Description

The Lokotrack® LT7150™ mobile VSI plant is the first choice in final stage crushing for producing high-quality cubical aggregates, road base and prime manufactured sand. The LT7150 is built around the proven Barmac® B series vertical shaft impactor featuring rock-on-rock crushing action.

 

Features

The crusher allows quick and easy operation and service, the possibility to steplessly control the product grading, and the production of superior cubical end products. The Barmac VSI's rotor accelerates the material and continuously discharges it into the crushing chamber. The particle exit velocities range between 45–70 m/s (150–230 ft/s). The crusher runs with a direct hydraulic motor, eliminating the need for V-belts. This allows tip speed to be fully adjustable from the automated control panel.

 

The LT7150 can be fed by conveyor, excavator or wheel loader thanks to the large feed hopper. The sturdy belt feeder takes the feed to the crusher. The efficient, environmentally friendly CAT® diesel engine powers the Lokotrack LT7150, meeting the latest emission requirements.

 

The market leading, user-friendly Metso IC™ process control system features complete automatic crushing process controls, single-button process start-up and advanced fault diagnostics.

 

Process overview

Lokotrack LT7150 is typically used in multistage crushing process in the third or fourth stage. Belt feeder transfers the feed material to the Barmac B7150 which reduces them to the desired size and shape. Main conveyor discharges the product in the stockpile.

 

How it works

The primary path for the feed material is through the stone lined rotor where material can be accelerated up to rotor tip speeds of 80 m/s (262 ft/s) before being discharged into the crushing chamber. Additionally, material may be cascaded into the crushing chamber, bypassing the rotor.
