Coated sand coated sand production method, mixed anatomy experienced dry mix, cold coating method, temperature coating, thermal coating method four stages, the current production of coated sand almost all thermal laminating method. Thermal coating process is the first raw sand heated to a certain temperature, and the resin respectively, Wuluo removal of aqueous solution and calcium stearate were mixed and stirred, cooled from crushing and screening. Due to differences in formulation, blending process is different. At present, domestic species, many coated sand production line, hand-feeding of semi-automatic production lines, about 2000 to 2300, Qingdao coated sand regeneration lines, computer-controlled automatic production line also has nearly 50, to effectively improve production efficiency and product stability . In the coated sand production areas should be strengthened following two aspects: (1) hair coated sand pollution, mainly from the following aspects: ① to reduce the amount of resin and curing temperature; ② coated sand to improve the overall performance, especially ③ strengthen pollution research phenolic resin substitutes; high temperature performance;. (2) increase the regenerative capacity of coated sand coated sand coated sand production equipment package recycling has been a topic of concern for the majority of experts, the current coated sand regeneration equipment is expensive and regeneration efficiency is not high, productivity is 5 tons / hour The thermal regeneration equipment prices in the 1200-1600 yuan, coated sand regeneration cost 65-90 yuan / ton coated sand reclamation line supply, this cost can not be cast for domestic enterprises type iron-coated sand process The process is a metal mold (iron type) cladding a thin layer of coated sand lumen crude shaped (3-8mm) to form a mold coated sand regeneration, see Figure 1. It is by all means coated sand reclamation line manufacturers, such as process testing, computer simulation, experience charts, reasonable set of iron-type wall thickness and the thickness of coated sand, sand casting system and coating materials to achieve so cast complete filling and solidification cooling at a more favorable conditions to improve its internal quality and surface quality purposes coated sand reclamation line supply | Qingdao Heng (certified) | coated sand regeneration provided by Heng Machinery Co., Ltd.
