The utility model provides a modified phenolic resin production system, includes main reation kettle, and main reation kettle connects feeding part, and main reation kettle still connects the condenser, and the vacuum dehydration part is connected to the condenser, main reation kettle lower part discharge gate johning knot mascerating machine, it is crushing that the cubic solid -state modified phenolic resin who obtains after the flaker processing goes into rubbing crusher, and the phenol -formaldehyde resin after smashing carries income packagine machine, and the basin is still connected to the flaker, carries for the flaker after the refrigerator cooling from the cooling water that the basin was exported. The flaker of this production system has improved liquid resin solidified speed greatly under the cooling water effect, the rubbing crusher who is connected with the flaker smashes the hard resin, has not only guaranteed the homogeneity of crushing back resin particles degree size, and has accelerated crushing speed, the metering device who is connected with phenol elevated tank and formaldehyde elevated tank has guaranteed that the raw materials adds the accuracy, has promoted the synthetic resin quality, this production system has production efficiency height, advantage that product quality is good.
