K-TEK’s Laser technology provides a solid and cutting edge solution to a challenging problem for a Montana coal mine. The customer wanted to automate its coal loading process in its coal barn storage facility, but the 700 ft. long x 100 ft. wide facility presented difficulty in overseeing and controlling the coal filling process and inventory stock take. A tripper car with dual chutes moving on an overhead rail structure facilitates the coal feed. While an operator manually controls the entire coal loading process, the dusty enclosed environment and large coal barn proved to be challenging for the operator’s ability to effectively and accurately control the process. K-TEK’s LM80 and LM200 Laser Transmitters were selected by the customer to automate the coal loading process and to provide real time system feedback for continuous stock measurement. In order to achieve continuous level measurement, K-TEK implemented an array of laser transmitters that were sufficiently spaced for inventory accuracy distance between them. At the same time, the LM200 Laser Level Transmitters, which are set to measure distance, continuously measures the position of the tripper car. The LM80 Laser Level Transmitters mounted on the traveling tripper chutes monitor the real time level fill while the tripper is in position for the coal dump. Solution: 1. Sixteen (16) LM80 Laser Transmitters were installed at 40 ft. intervals on the roof walkway to cover the entire length of the coal barn providing complete coverage of the 700 ft. long facility with acceptable coal volume accuracy and level information available 24/7.
