Abstract

The invention discloses a grinding and screening integrated device for recycling casting waste sand, which belongs to the technical field of casting waste sand recycling. The plate can stir the waste sand along different planes, so that the contact between the waste sand and the grinding assembly is more sufficient, so that the waste sand is more fully ground, and the grinding efficiency and effect are significantly improved, and the turning assembly and the grinding assembly pass through one Driven by a motor, it can effectively save energy and improve environmental protection performance. It is also equipped with a secondary crushing component for crushed pieces. As the turning plate stirs the waste sand, the crushing rod can squeeze the waste sand and then crush it. At the same time, multiple abrasive blocks can further squeeze and grind the waste sand, thereby further improving the grinding efficiency and effect, and after separation, the sticky particles separated from the sand particles can be automatically thrown out through the sieving hole. Adhesive coating reduces the workload of workers.

Description

technical field [0001] The invention relates to the technical field of recycling foundry waste sand, in particular to an integrated grinding and screening device for recycling foundry waste sand. Background technique [0002] Casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling and solidifying, and cleaning to obtain a casting with a predetermined shape, size and performance. Because the casting blank is almost formed, the purpose of free machining or a small amount of machining reduces the cost and reduces the production time to a certain extent. Casting is one of the basic processes of the modern device manufacturing industry. [0003] Sand casting refers to the casting method of producing castings in sand molds. Molding sand is the basic raw material for making molding sand in sand casting. In order to reduce production costs, it is necessary to recycle the used waste sand, because the surface of the sa...
