Chute feeder is a kind of feeding equipment which is earlier used in storage trough and it is suitable for the short-distance transport of metallic and non-metallic materials.
Spiral chute separator is the best equipment for mining and ore beneficiation. It is a kind of ideal equipment for mining sand.
In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.
This series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.
The disk grain making machine is suitable for the mixing ball equipment of the nutrient content is 10-30%.
Chinaware ball mill is mainly used for the mixing and grinding of materials, and the fineness of the final products is even, thus saving motive power. It can be used in both dry grinding and wet grinding.
Effect ofMillSpeed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. Themillwas rotated at 50, 62, 75 and 90% of thecriticalspeed. Six lifter bars of rectangular cross-section were used at equal spacing.
