The stirring system of VKM-5 Twin-shaft differential vertical kneader consists of mixing kettle, solid paddle and hollow paddle. The inner wall of the mixing kettle is a hollow thermal insulation layer, which is filled with 30 ℃ constant temperature water provided by the water supply system. The hollow paddle and the solid paddle are vertically installed.

Industrial solid waste not only pollutes the environment but also causes huge waste of resources, which is one of the important issues concerned by the comprehensive utilization of resources and environmental protection in the world. Therefore, large enterprises finally explore recycling technology through the successful application of cold briquette technology in solid waste recycling.

The large briquette machine consists of transmission motor, synchronous gear reducer, preloading device, main machine device,hydraulic system, belt conveyor and electronic control. Among them, the synchronous structure adopted by the transmission system makes the main engine transmission realize good design,manufacture, use and maintenance. The hydraulic device adopts the structure of small cylinder body and large tension force, thus realizing the purpose of reducing the quality of the whole machine and reducing the consumption of steel. The ball pressing roller adopts a combined structure, which realizes that vulnerable spare parts can be replaced on site, thus reducing the loss caused by the shutdown of the production line.

Forced conveying device with mixing function is one of the important equipment in plastic extrusion production line. The device adopts a screw with left and right rotation, driven by a deceleration motor. The materials at both ends of the screw are simultaneously transported to the middle of the screw by utilizing the conveying mechanism of the screw thread. When the materials transported in the left and right directions merge in the middle of the screw, some materials are forcibly transported to the processing equipment through the material conveying port which is in the middle of the mixing bin. Thus realizing the forced conveying function of the materials.
