The invention relates to a double-layer roller kiln for producing a lithium-ion anode material and a production technology thereof. The double-layer roller kiln and comprises an upper-layer kiln, a lower-layer kiln, roller bars, heater silicon carbide rods, air inlet systems, saggers, kiln head exhaust pipelines and kiln tail exhaust systems, wherein the roller bars are mounted inside the upper-layer kiln and the lower-layer kiln; the saggers can be operated above the roller bars; the air inlet systems are arranged below the roller bars of the upper-layer kiln; and the heater silicon carbide rods are arranged above the saggers operated on the roller bars of the upper-layer kiln and below the air inlet systems. According to the double-layer roller kiln, the anode material is produced through adopting the double-layer roller kiln device, and the parameters of the production technology are stable, so that the product consistency can be guaranteed; six rows of square saggers arranged in the 330*330 manner are operated in the kiln at each layer, and the number is five times that of a conventional single-layer four-row roller kiln sintering device; and according to the technology, the energy utilization rate is high, and the unit energy consumption is low, and is 60% of the energy consumption of the conventional single-layer four-row roller kiln sintering device.
