The demand for grinding dry materials is ubiquitous in food, chemical, pharmaceutical industries. From chili peppers and turmeric to traditional Chinese medicine, industrial customers often have vastly different requirements for grinding fineness, capacity, and temperature control. So we here recommend several powder grinder machines to you, which are universal grinders, hammer mills, air classifier mill, and cryogenic grinders. These machines can basically meet the grinding needs of most dry materials on the market.
These four grinding mills differ in many aspects, including their features, grinding effects, and applications. Below, we will provide a systematic introduction to the characteristics and applicable scenarios of each type of equipment to help you choose the right one.
Our SLU series grinder is universal grinder, it isn't truly "all-purpose," but its material adaptability covers the vast majority of dry materials.
Core Advantage: Different types of grinding discs/blades can be replaced inside the grinding chamber according to the material's characteristics, truly achieving "one machine for multiple uses."
Wide usage in the food industry: It can easily grind chili peppers, turmeric, yams, lentils, sugar, chickpeas, and more.
Cutter Types: Air-cooled hammer type, disc type, hammer type, blade type, turbine type
Fineness Control: Adjust the fineness of the finished product by changing screens with different mesh sizes (10-120 mesh).
Production Mode: Small single machines are used for batch production, while medium and large equipment are used for continuous production.
Flexible Design: Suitable for a wide range of materials.
Size: This type of equipment covers various models from small to large, catering to both small and large spaces.
Relatively Low Cost: Lower investment costs, suitable for startups and SMEs.
Our SL series and SLF series grinders can both be considered hammer mills. Hammer mills are equipped with hammer blades inside, they are particularly suitable for coarse and medium crushing of fibrous materials and spices.
SLF series: Suitable for leaves, Chinese medicinal herbs, and pharmaceutical grinding
SL series: Suitable for chili peppers, turmeric, ginger, cinnamon, etc grinding
Designed for Fibrous Materials: The hammer blades and screen work together to effectively cut fibers.
Pharmaceutical-Grade Configuration Optional: 304/316L stainless steel, meeting GMP requirements.
Controllable Output: Fineness can be adjusted by changing the screen.
Medium to High Continuous Operation: about 70-2,000kg/h
High Wear Resistance of the Hammer Blades: Special heat treatment ensures a long service life
Dust-Free Environment: Equipped with a dust collection system
ACM mill combines high-speed cutters with an air classification system, making them suitable for materials requiring high fineness (100-300 mesh or even finer). Our SLA and SLP series belong to this category.
SLA Series: High-speed blade assembly + air classification, suitable for food, chemical, and pharmaceutical materials with high fiber content or high fineness requirements. Under most cases, this machine is for 80-500mesh fine powder making use.
SLP series: The fineness of grinding is controlled by adjusting the gap between the grinding disc and the toothed ring. With the help of the air classification system, the fineness can reach 1000 mesh.
Special Design: Screenless air classification
Fineness Control: Adjustable via knob on classifying wheel speed, easy operation
Powder Quality: Narrow particle size distribution, excellent uniformity
Low Temperature Rise: Suitable for heat-sensitive materials
Working Principle: The fineness of the powder is controlled by adjusting the gap between the grinding disc and the toothed ring.
Fineness Advantage: Generally, the fineness is superior to the SLA series, but the cost is higher and the production capacity is lower.
Applicable Materials: Dried leaves, rice, Chinese herbal medicines, and other materials requiring super fine powder.
Our SLD series grinder is cryogenic grinder type, it is the ultimate solution for high-sugar and high-oil materials. Because this machine completely solves the problem of sticking and clogging for the high oil and sugar content.
Usage characteristics: Require use with liquid nitrogen, so it is essential to confirm the availability of a liquid nitrogen source near the factory beforehand.
Application scenarios: Suitable for crushing difficult-to-crush materials such as dried fruit, dates, nuts, mustard seeds, and coriander seeds.
The SLD series cryogenic grinder freezes materials to their brittleness point (typically -196℃) using liquid nitrogen, making high-sugar and high-oil materials brittle and hard. Then, high-speed blades pulverize the materials, fundamentally solving the problem of sticking and clogging.
High Quality Finished Product: Low-temperature embrittlement followed by pulverization results in high-quality powder.
Preserve Aroma and Color: Low-temperature oxidation inhibits oxidation, minimizing flavor loss.
Wide Applicability: This grinder can pulverize almost all materials, but the operating cost is high.
Above we have introduced the recommended four types of powder grinder machines, each with different grinding characteristics and application scenarios. The universal grinder offers the best value for money, with a wide range of blade changers suitable for most food, chemical, and pharmaceutical dry materials. The hammer mill is the mainstay for making medium-to-fine dry leaf, spice, and medicinal powders. The ACM mill is an expert in ultra fine powders, specifically designed for making ultra fine powders. Finally, the cryogenic grinder is specifically designed for grinding high-sugar and high-oil materials. To help you choose the right type more quickly, we have summarized the following points for your reference. Of course, you are welcome to contact Salinovate Team directly for recommendations on the specific grinder machine.
Applicable Fineness
Universal grinders and hammer mills are suitable for 10-120 mesh; other grinders offer better fineness.
Fineness Adjustment Method
Universal grinders and hammer mills adjust fineness via a screen; other models do not.
Production Efficiency
Small, batch-production machines have lower efficiency; SLP with high fineness requirements also have lower efficiency.
Raw Material Type
For low to medium oil content, consider universal grinders and hammer mills; for high fiber content, consider hammer mills and ACM mills.
Fineness Requirement
If the requirements are not high, universal grinders or hammer mills can be used; ACM mills are required.
Purchase Cost
Cryogenic grinders have the highest overall operating cost, and ACM mills are also relatively expensive.
