The company had already purchased its first Lokotrack®, the LT1110™ impact crusher, several years ago. Thanks to their positive experience of the Lokotrack, it was not long before they purchased another, the LT106™ jaw crusher and LT1110S™ impact crusher equipped with a screen, in 2016.
“We are very satisfied with the availability of our Lokotracks. Not only are they always ready to operate, they are easy to transport and maintain. Spare parts are always available at short notice, even for our 14-year-old system,” notes Frank Theune, head of operations at the Schwarzenhasel quarry.
Throughput constantly exceeds 200 t/h
The LT1110S has been in use since Spring 2016. It crushes limestone with a particulate size of 0–400 mm, which is extracted without blasting using a bagger. In a closed circuit with 35–40 mm closed side setting, it produces over 200 t/h 0–45 mm. The oversize is about 15% of the crusher output. This goes back into the crusher via the oversize return belt.
The end product of the LT1110S is classified as needed into various grains, such as 0–2 mm, 0–22 mm, 1–32 mm, 1–45 mm or 6–22 mm using a separate mobile screen. The customers for these products are located at a distance of up to 50 km from the surrounding area of Bebra.
At the Schwarzenhasel quarry, the LT1110S runs up to 16 hours a day and produces around 180,000 tons a year. The fuel consumption of the impact crusher with screen module and oversize return belt is so small that the tank capacity of 500 L is enough for daily production with two shifts without the need for fuel stops.
Extended warranty to protect operations
Beisheim has concluded an extended two-year warranty with Fischer-Jung for the LT1110S. Regular maintenance work, including oil changes and wear part replacement, is performed by Fischer-Jung.
