Rx4.0m/m SM-40 spiral steel silo forming machine is the forming machine for the circular steel plate storehouse (a metallic container), which we released in the market in 2005. It is a new SM-40 spiral steel silo forming machine designed on the basis of the LIPP-SM40 machine from Germany. It has all the functions that the SM40 machine has. Additionally, it is made of a high-strength alloy steel structure, which is durable and can last a long time. Compared with SM40, it is easier to install, maintain and operate. This makes it more competitive in terms of its cost and service life.

SM-40 spiral steel silo forming machine makes cylinders that can be used in the food, brewing, petroleum, medicine, water curing and more industries. The manufactured cylinders can also be used as storage facilities for wheat, soybean, corn, flour, fly ash, sewage, chemical syrup, recycled water, among others.
