Step 1: Drying Process

The drying process plays a crucial role in obtaining finely powdered henna leaves. Utilizing a YDHF series hot air tray drying oven machine ensures efficient drying while preserving the natural properties of the leaves.

Structure: The YDHF series oven features a tray system that allows uniform heat distribution, preventing uneven drying and preserving the vibrant color and medicinal properties of the henna leaves. It also has a simple structure: the stainless steel 304 frame, the tray, the baking car, the fan, the electric control box.

Working Principle: Hot air circulation within the oven removes moisture from the leaves without compromising their quality. This controlled drying process ensures that the leaves are ready for the next stage of grinding.

Features:

stable temperature control
automatic timer setting
durable construction to withstand continuous use.
various application, such as chemical, pharmacy, food industry, etc.
Various heating methods for your option to fit your local energy standard. such as electric heating, steam heating, hot water heating, etc.

Step 2: Grinding Process

Achieving an ultra-fine powder requires precision in the grinding process. Depending on the capacity, two types of grinding machines are recommended:

Small Capacity Grinding: 10-100kg/h, 100-200 mesh

For small-scale operations, the YINDA YDZFJ series henna leaves grinding machine herbal pulverizer is ideal.

Structure: The YINDA YDZFJ series henna leaves grinding machine herbal pulverizer consists of a grinding chamber, cyclone assembly, and a collection chamber for the finely ground powder.

Working Principle: The henna leaves being feed into the grind chamber through the upper feeder, is pulverized by high-speed running blades. The fineness of the finished products is regulated via the distance adjustment of grading wheel and grading plate. The highspeed running fans will lead those pulverized material from grinding chamber to discharge gate via negative pressure while whose unpulverized remained in the chamber. The dust from grinding is filtered and recycled via the cloth bag or filter of the dust absorption box.

Features:

Compact design, small footprint and easy to transfer.
ease of operation, one button control the system.
Stainless steel 304 with inner and outside polishing treatment which is easy to clean and to maintain.
Low project cost and low energy consumption.
No sieve, good for long time high speed grinding.
Various applications: such as chemical, pharmacy, food industry, etc.
High Capacity Grinding: 100-1000kg/h, 100-320 mesh

Large-scale production benefits from the YINDA YDWF series Henna leaves grinding machine ACM MILL.

YDWF series Henna leaves grinding machine ACM MILL

Structure: YINDA YDWF series henna leaves grinding machine ACM Mill consists of the air classifier milling part, the cyclone dust free system, the centrifugal fan, and the electric control box. It features an advanced air classifying mill with a dynamic air classifier to achieve ultra-fine particle sizes.

Working Principle: The henna leaves are introduced into the grinding chamber, where they undergo multiple impact and classification processes, resulting in a highly refined powder. The superfine powder and dust will be absorbed into the dust collector by the cyclone dust free systm which is meet the high quality environmental requirement.

Features:

Air Classification System: The ACM Mill incorporates an advanced air classification system that separates and classifies particles based on their size and density. This ensures precise control over the final particle size distribution.
Impact Milling Technology: The ACM Mill uses impact milling, where high-speed hammers or pins strike the material, breaking it into smaller particles. This technology is effective in reducing the particle size to achieve ultra-fine powders.
Versatility: YINDA YDWF series henna leaves grinding machine ACM Millsare versatile and can handle a wide range of materials, making them suitable for various industries. They can process materials with different hardness levels and particle sizes.
High Production Capacity: The YINDA YDWF series henna leaves grinding machine ACM Mil is designed for high-capacity production, making it suitable for industrial-scale applications. It can handle large quantities of material efficiently, contributing to increased productivity.
Precise Particle Size Control: The mill provides precise control over the particle size distribution, allowing for customization based on specific application requirements. This feature is crucial in industries where uniform particle size is essential.
Customization Options: Manufacturers often provide customization options for ACM Mills to meet specific processing needs. This may include variations in size, power, and additional features tailored to the user’s requirements.

Step 3: The optimal Auxiliary Equipment

During the high-speed grinding process, the temperature in the crushing chamber will be around 50-60 degrees, considering henna leaves are sensitive to the temperature, we recommend the cooling chiller as the optimal auxiliary equipment to work together with the grinding machine, to cool down the temperature into -5-10 degree which will prevents the loss of essential oils and preserves the color and medicinal properties of the henna powder.
