GS Coated Sand Production Line for Sales

Film mulching process: With reference to the automatic process and equipment of coated sand, the production line of coated sand designed by our company is first designed to design three pneumatic switches at the bottom of the original sand bucket No. 1 and No. 2 and the third iron sand bucket, respectively. According to the process, the raw sand and the iron sand needed to be dropped in the bottom of the electronic weighing system are used. The iron sand is slightly farther away from the electronic weighing, so the screw feeder is used to place the iron sand in the electronic scale. It takes 20s to add the raw sand and iron sand to the secondary process of the drum heating furnace quickly after the electronic proportioning of the raw sand and iron sand, and the sand of the drum heating furnace is added by 2min30s. It takes 20s to unload the sand into the mixer at the right heating temperature, and the drum is in reverse state, and when the sand is unloaded, the drum stops from the reverse state to turn back, and then the second heating begins. The sand under the mixer begins to add resin after 15 s. The resin is electrically called the lower resin weighing bucket pneumatic door to open and close after adding. The two resin storage hops above the resin (which need not be matched with one resin hopper) are added to the resin needed by the electronic weighing inner phase separately through the screw feeder. After the resin weighing is finished, the screw feeder stops, and the resin electronic weighing starting door is opened. Put it into the weighing hopper and wait for the next signal, mix the 50-70S aftercare product, when the signal is passed to the metering pump (time metering) and add a certain quantity, then mix the 40-60S and add the calcium powder, After receiving the signal, the calcium powder is opened by the air valve of the reserve bucket that is poured by the screw feed material above the sand mixer, and then closed after discharge. Screw feeders are added to the calcium powder storage bucket (time metering) again, waiting for the next addition. 5 s after the bottom blast cooler opens 10-30s to unload the sand, after unloading the sand (15 s), the mixer pneumatic door closes, and so on, and so on. Synthetically because each company craft different season is different we may according to your company need craft to write the relative procedure in this does not do one elaboration here forgets the understanding. Cooling part After unloading the sand mixer, the coated sand is first crushed by vibrating crushing screen, then into the first cooling line after the hoist, then into the second cooling channel, then into the second cooling, lengthening the water cooling drum, and then to the hoist hoist to reach the reserve sand bin.
