Common problem

How many tons of clay sand treatment line is needed for the automatic horizontal casting molding production line


黏土砂砂处理线主要作用是回收利用造型线的旧砂,通过落砂—破碎—筛分的等步骤处理后混合搭配新砂,重新为造型线造型主机提供射砂用砂。正常运行生产中全自动水平造型线单主机需配备25吨的黏土砂砂处理生产线,即主机联动不停机不下芯的情况下,以510mm x 610mm的砂箱尺寸造型机,每小时的黏土砂消耗量为8吨左右。

The main function of the clay sand processing line is to recycle the old sand of the molding line, mix and match the new sand through the steps of sand falling, crushing and sieving, and provide sand for shooting for the molding machine of the molding line again. In normal operation, the automatic horizontal molding line needs to be equipped with a 25 ton clay sand processing production line for a single main machine, that is, when the main machine is linked without stopping or dropping the core, with a 510mm x 610mm sand box size molding machine, the clay sand consumption per hour is about 8 tons


The single machine equipment of clay sand processing line mainly includes vibration sand remover at the end of molding line, advanced magnetic separation, sand return belt, crusher, roller screen, hexagonal screen, boiling cooling bed, pulse dust remover, bucket elevator, right angle screen, used sand silo, high-speed rotor sand mixer and stock bin, etc., so as to realize integration, standardization and automation of the whole line, improve sand mixing efficiency and save labor At the same time, the dirty, disordered and poor working environment of the foundry was improved, which met the requirements of environmental protection policies.


如若工厂厂房空间高度或企业资金受限制,使用“摆地摊”的形式单以造型机代替手工造型,也可搭配简易的砂处理线,但鉴于以往的现场使用情况来看,简易砂处理线主要存在的问题在于无法处理旧砂长期反复利用中积累的粉尘,特别是以下覆膜砂泥芯较多的铸件生产,需定期往旧砂中掺入新砂保证型砂的透气性,并且在旧砂的混砂过程中人工对于水分以及原料的搭配不容易掌控,因此我们建议针对于铸件要求较高,光洁度要求较高的应当配合标准的黏土砂砂处理线。(上图为两台550mm X 650mm/460mm的全自动造型机使用设计的30吨黏土砂砂处理生产线

If the space height of factory buildings or enterprise funds are limited, the form of "floor stand" can be used to replace the manual molding by molding machine alone, or it can be matched with simple sand treatment line. However, in view of the previous field use, the main problem of simple sand treatment line is that it can not deal with the dust accumulated in the long-term repeated use of used sand, especially the following casting with more coated sand cores In the production of parts, it is necessary to regularly add new sand into the old sand to ensure the permeability of molding sand, and in the process of sand mixing of old sand, it is not easy to control the matching of water and raw materials. Therefore, we suggest that the clay sand treatment line with high casting requirements and high finish requirements should be matched with the standard. (the above figure shows the 30 ton clay sand treatment production line designed by two 550mm x 650mm / 460mm automatic molding machines)
