METHOD OF COMPACTING COAL MASS IN SEAMS OF ALUMINIUM CELL BOTTOM

摘要

use: a lump coal mass in the hem u043fu043eu0434u0438u043du044b aluminium electrolytic cells in their manufacture or overhaul. self: you u043fu0440u043eu0438u0437u0432u043eu0434u00a0u0442 coal mass to a height of 100 to 200 mm and u0443u043fu043bu043eu0442u043du00a0u044eu0442 through vibration tool at a frequency variation within 2000 to 9000 a / c with the accumulated pressure of not less than 1.2 kgf / cm.this leads to improve the quality of the seam and the efficiency of the process.
