Wet grinding is a grinding process used to produce a powder or paste from a solid using a liquid such as water. It can also be used in an abrasive process to reshape hard objects. There are numerous items that can be processed in this way, including grains and minerals. These techniques are used for domestic and industrial tasks. When used in industrial settings, a wet technique is often more cost effective than dry grinding.
Wet grinding is a process that has been around for a long time. The process has already been done using the mechanical energy of the stones. Nowadays, there are machines available that make the job much easier.
Electric wet grinders come in many sizes. Some are small enough to be used on a home kitchen counter. Others are large enough for commercial use in industrial facilities.
These machines generally involve wheels or balls that are used to grind materials as liquid is fed into the mix. This often results in a muddy type of mixture. Depending on the end use of the materials, they may need to be dried before use.
Electric grinders are often used in kitchens to reduce food for consistency when making sauces or sauces. Many people in India use wet milling to produce pastes and other products such as garam masala and chutney, which are popular ingredients in their dishes.
Wet grinding is often preferred by those in industrial settings because the process can have several advantages. It consumes less energy than dry grinding. This means that more material can be crushed using significantly less energy.
This process also provides an economical means of producing fine granules. Dry grinding is generally not comparable. Attempting to produce fine particle sizes using a dry grinding technique can be energy intensive and therefore expensive. Even when this is done, the particles may not be as small as they would be if a wet process were used.
When dry grinding is done, a large amount of dust is often generated. This often requires investing in special equipment to capture or control this dust. With wet grinding, this type of investment is usually not necessary.
The liquid involved in the grinding process can also make it a better option. When items such as metal are ground, especially using a dry method, a great deal of heat can be generated. If a liquid is present, such as in wet grinding, it can act as a coolant that can protect the worker, the machine, and the material being processed.
