It is commonly used to crush granular materials and pulverize them into powder, mainly used in the fields of medicine, agriculture, and food production. Small pulverizers with hammers, also known as hammer mills, are another common type of small pulverizer. It uses high-speed rotary hammers to impact and crush materials, which are then screened into powder. Due to its versatility and adaptability, the hammer pulverizer is widely used in various industries, such as food processing, chemical, and pharmaceutical industries.

Grinding is the main method of grinding. It uses two toothed disks to crush materials. The powder size can be adjusted by changing the distance between the two grinding discs. The pin mill is a small pulverizer that uses high-speed rotating hammers to hit materials and break them apart. It is widely used for grinding various materials, such as food, spices, and chemicals. The colloid mill works by shearing or cutting the material, which results in size reduction. This type of pulverizer is suitable for reducing the size of food products like peanut butter and mayonnaise. Cage mills, also known as multi-row cage mills, are another type of pulverizer that reduces the size of the material by striking it with cage-like hammers. The cage mills are versatile and can be used to crush coal, stone, and other materials used in the construction industry.

Aside from the aforementioned, there are other types of pulverizers, such as rolls mills, which are used to crush materials between two rolls or cylinders. They are ideal for coal, brick, and clay. Turbo mills use multiple blades to create high speed and air flow. They are ideal for chemicals, food, and pharmaceutical industries. Another type of pulverizer is the ultrafine pulverizer, which is used to crush materials to a very fine size. The machine is suitable for use in the chemical, pharmaceutical, and food industries.

How to choose small pulverizers

When selecting a small pulverizer, there are many factors to consider. Some of the most important include the intended material, the required output, and the space available for the device. The material the pulverizer will process will largely determine the type of pulverizer needed. For instance, some materials will require a hammer mill, while others will require a disc mill. For instance, a customer looking for a small wood pulverizer should go for a hammer mill because it works well with materials like wood. On the other hand, a customer in need of a small food pulverizer should consider a disc mill, which works well with food materials.

Another crucial factor to consider is the required output. This includes factors like the desired particle size and the capacity of the pulverizer. Some customers may prioritize the production capacity over the desired particle size. In this case, they should go for a machine that can handle large amounts of material. Also, they should look for models with adjustable screens and hammers. Such models give them the flexibility to fine-tune the machine to suit their desired particle size.

Customers shopping for a small machine should also consider the model's size and power requirements. Small models are easy to set up and cost less to power and run compared to large machines. With proper use, a small pulverizer can serve for many years without the need for frequent repairs. However, they should ensure that the pulverizer is a suitable fit for its intended application and production needs.

Finally, it is important to consider the available budget and any specific features or specifications required.
