The invention provides a novel grinding roller shell hoisting tool. The novel grinding roller shell hoisting tool comprises a connecting block and a lifting block, the mounting opening is formed in one side of the connecting block, two mounting holes are formed in the front face of the connecting block, a fixing bolt is arranged in one of the mounting holes, a nut is in threaded connection with the position, close to the other end, of the outer portion of the fixing bolt, and a movable block is rotationally connected to the outer portion of the fixing bolt; the bottom of the movable block is fixedly connected with a first lifting hook, and the connecting bolt is mounted in the other mounting hole. According to the novel grinding roller shell hoisting tool, the three sets of first lifting hooks and the limiting hooks are matched to enable the grinding roller shell and the grinding roller shell to be clamped through the gravity of the grinding roller shell, the industrial efficiency is greatly improved, manpower and material resources are saved, and the tool has the advantages of being low in cost, convenient to install and carry and the like. The sight of a crane operator is not influenced in the use process, and safe and smooth maintenance of the coal mill is ensured.
