High Quality Coated Sand Production Line

Coated sand and sand roasting engineering part

shakeout of castings :

the cast part and the sand box disc which are cast are sent to the annular hanging cabinet at the vibrating crusher at the roasting wire by a forklift for a period of time , the casting is put into a storage box to be filled with a fork truck fork after being cooled for a period of time , the sand box disc is connected with the crane block by an iron chain , the two ends of the sand box plate are connected with the iron chain by the iron chain , the two ends of the sand box plate are conveniently connected with the iron chain , and the hoisting good sand box disc can be horizontally turned over by manual operation , thus greatly reducing the labor degree and the diffusion of dust .

Old sand roasting :

the invention relates to a spiral feeder which is used for quantitatively and accurately feeding sand in a king roasting furnace .

2.2 Film - coated sand - covered work part

Film coating process :

The invention relates to an automatic process and equipment for sand - coated sand , which comprises the following steps : firstly , three sand bins are arranged below three ports of an original sand No.1 hopper and a No.3 iron sand hopper , three pneumatic switches are designed ;

the cooling section

the sand - coated sand after sand discharging of the sand mixing machine is firstly crushed by a vibration crushing sieve and then enters into a first passage for cooling , the vibration is boiled and cooled , then enters a second passage for cooling , and the water cooling roller is lengthened , and then reaches the reserve sand bin after the hoisting machine is lifted .
