The equipment is mainly used for the compression treatment of solid radioactive nuclear waste, which can greatly reduce the volume of the barrel containing solid radioactive materials, and the high volume compression ratio and small package size can meet the requirements of efficient and economical capacity reduction of users. The pressing force of the equipment is more than 20000kN, and it integrates the functions of centering the barrel, piercing the barrel wall, sealing of the mold sleeve, compression and pressure preservation, automatic separation of the mold sleeve and pressure cake, directional discharge of waste gas liquid and centralized collection, etc., and the safety protection level of the equipment is extremely high.
