What is the YINDA salt grinding mill machine?
YINDA salt grinding mill machine is also known as a salt grinder, salt mill, or salt pulverizer, etc., which is a device used to grind salt crystals into finer particles. It is commonly used in food factory and seasoning industry to make various finished food or complex seasoning products. The purpose of a salt grinding mill machine is to crush the salt crystals into smaller sizes, allowing for easier dissolution and dispersion of salt when seasoning food. Besides, In the market, normal grinding mill machines adopt SUS 304, but considering the corrosion of salt, YINDA will take food grade antibacterial and corrosion-resistant SUS 316L to make the YINDA salt grinding mill.
How to choice the YINDA salt grinding mill machine?
As we all know, according to different applications, the requests for the salt powder size will be different. Based on our rich experience and the market research result, the salt powder size request can be classified into two ranges, 20-120 mesh and 120-300 mesh. For these two ranges, we have developed different models of equipment to effectively solve the salt crushing problem.

How dose the YINDA YDWS series pin mill salt grinding mill machine work?
YINDA YDWS series pin mill salt grinding mill is used for pulverizing or grinding various materials into fine powders. The grinder consists of a rotor with closely spaced pins or blades that rotate at high speeds, impacting the material and together with the screen to reducing it in size.
Let us introduce two important parts in the YINDA YDWS series pin mill salt grinding mill for you to help you know more about this series.
- The adjustable inner filter screen
Due to the adjustable inner filter screen around the rotating blade to assist the blade to get the regular sized powder, the YINDA YDWS series pin mill salt grinding mill is also called YINDA YDWS series screen mill salt grinding mill.

YINDA YDWS series pin mill salt grinding mill with the screen
The filter screen of a salt grinding mill machine, also known as a pin mill sieve or mesh, is an essential component that helps control the particle size of the ground material. It serves as a barrier that allows only particles of a certain size to pass through while retaining larger particles within the grinding chamber. The particles that are small enough to fit through the screen are collected as the final product, while larger particles remain in the grinding chamber until they are reduced to the desired size. The filter screen is selected based on the desired particle size distribution for the specific application.
It is made of perforated metal or wire mesh with precise hole sizes. The size of the holes in the screen determines the fineness of the ground material. Smaller hole sizes result in finer particles, while larger holes produce coarser particles.
The filter screen in a pin mill grinder machine is removable and replaceable, allowing for easy cleaning and maintenance. Regular cleaning of the screen is necessary to prevent clogging and ensure optimal performance. The screen should be inspected periodically for wear and damage and replaced when necessary to maintain the desired particle size distribution.
In summary, the filter screen of a pin mill grinder machine plays a crucial role in controlling the particle size of the ground material. It allows only particles of a specific size to pass through while retaining larger particles, resulting in the desired fineness of the final product.
- The grinding discs
The grinding discs used in YINDA YDWS series pin mill salt grinding mill are typically made of stainless steel or hardened steel. These discs have a series of closely spaced pins or blades that rotate at high speeds to effectively grind or pulverize the material being fed into the mill.

YINDA YDWS series pin mill salt grinding mill two types grinding discs
During the grinding process, the material is fed into the pin mill grinder machine through a feed inlet. The rotating pins or blades strike the material, causing it to break apart and pass through the filter screen. The material of the grinding discs is chosen for its durability and resistance to wear and corrosion. Stainless steel is commonly used due to its strength and non-reactivity with many substances. Hardened steel, on the other hand, offers excellent hardness and toughness, making it suitable for grinding abrasive materials.
- Powder size is around 120-300 mesh: YINDA YDWF series ACM MILL salt grinding mill machine
In response to the changing market demand for products, many products need a finer powder to achieve results, so the YINDA ultra-micro pulverizer YDWF series ACM MILL salt grinding mill was born.
YINDA YDWF series ACM MILL salt grinding mill machine
TheYINDA YDWF series ACM mill salt grinding mill (Air Classifier Mill) is a type of grinding mill machine commonly used for grinding various materials, including salt. It is designed to combine the functions of grinding, classifying, and collecting in a single unit, the dust control system (cyclone separator, the pulse dust collector, etc) to improve the powder yield and to reduce the dust. The ACM mill utilizes a high-speed rotor with closely spaced grinding elements and an integrated air classifier to control the particle size distribution. so it is also called screen-less mill.
How dose the YINDA YDWF series ACM MILL salt grinding mill machine work?
When it comes to grinding salt in an ACM mill, the following process typically takes place:
1.Feeding: Salt is introduced into the mill through a feed chute or hopper with a screw feeding system.
2.Grinding: The high-speed rotor with grinding elements (such as pins or hammers) rotates rapidly, impacting the salt particles and reducing their size. The grinding elements and the liner of the mill chamber are usually made of stainless steel to prevent corrosion.
3.Classification: The ground salt particles are carried by the air flow generated by the rotor and enter the integrated air classifier. The classifier separates the particles based on their size, allowing only the desired fine particles to pass through while larger particles are returned to the grinding zone for further processing.
4.Collection: The fine salt particles that have passed through the classifier are collected in a separate container or bag, while the coarser particles are recirculated for further grinding.
- dust control system: the qualified superfine powder enter the cyclone separator to enter the discharge port, the dust or over micron powder enter the dust collector.
Lets show you the crushing chamber to know how it work as the screen-less mill.

The grinding chamber of an ACM (Air Classifier Mill) is an essential component where the grinding and classification of materials take place. It is designed to accommodate the grinding elements, the air classifier, and provide a controlled environment for effective particle size reduction. The exact design and construction of the grinding chamber may vary depending on the specific material and model of the ACM mill. However, here are some general characteristics:
- Shape and Size: The grinding chamber is typically cylindrical or conical in shape. The size of the chamber can vary depending on the desired capacity and throughput of the mill.
- Material: The grinding chamber is constructed using materials that are resistant to wear and corrosion. Stainless steel is commonly used due to its durability and non-reactivity with various materials being processed. The interior surface of the chamber may also have protective coatings or liners to enhance wear resistance.
- Grinding Elements: The grinding elements, such as blades, are mounted on a high-speed rotating rotor inside the grinding chamber. These elements impact and grind the material as it passes through the chamber. According to the control of the inverter to get different powder size. The design and arrangement of the grinding elements can vary depending on the specific application and desired particle size distribution.
- Air Classifier: The grinding chamber incorporates an integrated air classifier, which is responsible for controlling the particle size distribution of the ground material. The classifier separates fine particles from coarse particles and directs them with the guide ring to their respective outlets. The exact configuration and design of the air classifier can vary among different ACM mill models.
- Air Flow: The grinding chamber is designed to facilitate the passage of air or gas, which is used to convey the material and aid in the grinding and classification process. The airflow is typically generated by a fan or blower system, and it helps to transport the ground material to the collection system while controlling the particle size distribution.
