Research and Development of a New Laboratory Mill

Abstract

This paper studies a new mill, which is developed particularly for the laboratory scale, with respect to the problems of low efficiency and bad adaptability of mills commonly used in laboratories. The paper briefly introduces the machinery construction, working principle, performance characteristics and grinding test methods. The main shaft of the mill is driven to rotate by the motor drive variable-speed system (speed control system), it could be equipped with cylinders of different volumes, the working speed and grinding intensity are adjustable; running cycle time is automatically controlled and adjustable, which eliminate the adverse effects caused by manual control errors. The results show that this machine could change the dosage scale of test materials in a large range, facilitate the grinding materials tests of different ores and different scales, and greatly improve the test efficiency and equipment’s adaptability.
