The invention relates to an alumina conveying system and method, including directly conveying alumina to the hopper of a bucket type hoister from chute and hoisting the alumina to top of alumina bin by the bucket type hoister. The invention conveys alumina by utilizing a bucket type hoister instead of a pneumatic hoisting device initially in alumina production, thus greatly reducing power consumption of hoisting alumina vertically; besides a travelling apron is spared, conveying link is reduced, and horizontal conveying power consumption is reduced; and dynamic conveying is changed into static conveying, thus greatly reducing abrasion in conveying process. Practice shows that power is reduced to 75kW from original 185kWx2 under the conditions that conveying capacity is 300t/h and material is hoisted to the top of alumina bin by utilizing a steel wire adhesive tape bucket type hoister instead of a pneumatic hoisting device.
