Abstract

The invention provides a sand making system and a control method. The sand making system comprises a material bin, a conveying device, a lifting device, a crushing device, a powder selecting device, avibration screening device and a storage metering device. The conveying device is arranged between the material bin and the lifting device and used for conveying raw materials and / or recycled materials to the lifting device. The lifting device is used for lifting sand making materials containing the raw materials and / or the recycled materials. The crushing device is used for crushing the sand making materials. The powder selecting device is used for separating the to-be-output materials from the to-be-recycled materials. The vibration screening device outputs the to-be-output materials and sends the to-be-recycled materials into the storage metering device to become the recycled materials. The storage metering device stores and meters the recycled materials and further conveys the recycled materials according to the feeding amount of the raw materials, so that the recycled materials serve as at least one part of the sand making materials and enter the lifting device again. The recycled materials are stored and metered through the storage metering device, accurate calculation of the recycled material amount is achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sand making, in particular to a sand making system and a control method. Background technique [0002] In the related art, the recycled materials in the sand making system are directly returned to the conveying device, fed through the conveying device, and participate in the cycle of the sand making system again. This circulation method leads to a decrease in the yield of the sand making system and affects the production efficiency of the sand making system. Contents of the invention [0003] The present invention aims to solve at least one of the above technical problems. [0004] Therefore, the first object of the present invention is to provide a sand making system. [0005] The second object of the present invention is to provide a control method. [0006] To achieve the first objective of the present invention, an embodiment of the present invention provides a sand making system, including a mat...
