<p>A hopper and a manufacturing method thereof. The hopper comprises a hopper body (1). The inner circumferential surface of the hopper body (1) comprises a working surface. The hopper body (1) is manufactured by using a light-metal alloy; and the working surface is covered with a wear-resistant layer. A pumping system. A hopper of the pumping system is the foregoing hopper. The hopper is light in weight, good in wear resistance, easy in repair and long in service life; the manufacturing method of the hopper is simple and saves electrolyte; and because the pumping system has the hopper, both bearing load and the maintenance cost are reduced.</p> |
