Because wall putty is so widely used, numerous Paint Manufacturers have started making it. With a market value of more than Rs 3,000 crores, it is already a mature market.
As you very well know, wall putty serves as a protective base for pricey paints on interior and exterior walls. In order to smooth out surface flaws like cracks, it is also used to level the surfaces of walls. One major aspect that will increase the need for wall putty in the near future is the tremendous growth in infrastructure development projects, coupled with residential and commercial developments, in both developed and emerging regions.

Putty Manufacturing Process:
White cement and dolomite are the basic components of putty in the right amounts. Typically, the ratio of white cement to dolomite in a formula is 1:4. For instance, 5 Tonnes of Putty will contain various minor materials in addition to 1 Tonne of White Cement (BD – 1100 Kg/m3) and 4 Tonnes of Dolomite (BD – 950 Kg/m3).
The fundamental manufacturing process is broken down into four steps:
- Unloading and storing raw materials
- Ingredient weighing or batching
- Transmission of raw materials to charging hoppers
- blending and combining
1) Unloading and storing raw materials
The sizes of raw materials typically range from tiny bags weighing 25 kg and 50 kg to large bags weighing 1000 kg. These bags must be unloaded and the raw materials must be fed into the conveying system using bag slitting equipment for small bags and an electric hoist & bag massager system for large bags.
The amount of raw materials can be chosen based on the final outcome. White cement and dolomite are the first raw materials to be moved into storage silos in bulk. Pneumatic conveying systems are preferred for transporting the material to silos because they are reliable, inexpensive, and easy to operate and maintain. The amount of raw materials we wish to stock in these silos will determine their capacity. Typically, it could take anywhere from 3 to 6 days. Cones must be fluidized in order to prevent raw materials from becoming jammed inside the silo. Furthermore, bin activators are also employed as an extra measure of safety.
2] Ingredient weighing and batching:
To guarantee premium quality Putty powder, the ingredients should be mixed in specific proportions (given by formula). As a result, a hopper with weighing cells must be installed beneath the storage silos. Screw conveyors should be used to transport raw materials from the silo to the weigh hopper. Once the correct amount of material is in the weighing hopper, it will be dosed to the charge hopper via the conveying line via rotary airlock valves.
3] Transmission of raw materials to charging hoppers:
The raw material must now be transported to the required charge hoppers. Diverters in the conveying line are used to choose the charge hoppers. The blender batch cycle time determines the conveying capacity. Conveying air is estimated and a blower is chosen based on the capacity requirement and distance. The average carrying air velocity is between 25 and 30 meters per second.
4] Blending and combining:
After being charged in a charge hopper, the material is dosed in a blender/mixer through a screw conveyor. The average blender mixing time ranges from 15 to 30 minutes. The material is subsequently transported to a packing machine and packed. The finished good is subsequently moved to the finished good storage room.
A PLC panel can be used to control all system activities.
The system measures the precision of various raw materials blended in the ingredients using PLC programming, resulting in a superior-quality Putty powder. As a result, it reduces labor effort while simultaneously polluting the environment. As a result, it’s a win-win situation for everyone.
We hope that this article has given you a better understanding of the Putty production process and how the lean phase pneumatic conveying system makes the entire Putty manufacturing process easier and more automated.
