The new solution simplifies crushing operations, incorporates significant noise protection and cuts dust emissions remarkably, minimizing the impact for people living and working around construction sites.
"We developed this new solution to make it possible to run crushing operations in the most heavily regulated urban environments. Obtaining environmental permits is very tough when crushing in densely populated areas. The new Lokotrack Urban series, however, provides robust crushing power while minimizing the impact for people and communities around the site," says Jouni Hulttinen, Product Manager, Lokotrack mobile crushing plants, at Metso.
Environmental permits usually regulate the noise level caused by the crushing operations. From occupational health and safety perspective, 85 decibels is the most common level defined that requires ear protection, although even much lower levels can be disturbing for people living or working around crushing sites. With the noise-protected Lokotrack Urban LT106, the required protection distance drops up to 60% from 23-25 meters to 9-11 meters (from 75'-82' to 30'-36'). Outside this area, the sensory impact on the human ear can be even more significant.
"The test results are impressive. Naturally, we need to keep in mind that process noise is also highly dependent on other equipment used on site. The new Urban series is first of its kind that adapts to all crushing operations and actively protects the health and safety of the plant personnel and civilians," Hulttinen continues.
In addition to very low noise emissions, the Lokotrack Urban series includes a very advanced dust suppression system. The dust is funneled to stay inside the mobile crushing plant and a high-pressure water spraying system absorbs most dust particles from the air. The environmental features integrated into the mobile plant do not require any special maintenance. The crushing plant is also very easy to move from one site to another.
Disclaimer notice: Process noise is highly dependent on process parameters, such as feed material, feed size, by-pass arrangements, crusher setting and ambient temperature. Actual values may vary depending on operation conditions and other equipment used on site. Metso Minerals, Inc. accepts no additional responsibility related to the noise information provided in this example. Always follow your local occupational health and safety administration regulations.
