Commercial Powder Grinder

The working principle of commercial powder grinder is mainly based on precise mechanical mechanics design, through a series of complex and efficient mechanisms to achieve the material extrusion crushing and friction grinding. When the material is fed into the mill through the inlet, it will first encounter the high-speed rotating grinding rollers. These rollers are usually made of high-strength, wear-resistant materials, and their surfaces are specially treated to enhance the crushing and grinding effect on the materials.
Under the action of the grinding rolls, the material is strongly squeezed and crushed, and its particle size is rapidly reduced. At the same time, the friction between the grinding rollers and the material further promotes the grinding process of the material, which gradually refines it into powder. In this process, the adjustment device inside the mill plays a crucial role. By adjusting the spacing between the grinding rollers, the particle size of the powder can be precisely controlled, so as to meet the strict requirements of different industries on the fineness of the powder.
The ground material will enter the powder selecting device for further screening. Powder selecting device usually adopts advanced classification technology, which can accurately separate the powder that meets the requirements and the coarse particles. The compliant powder will be discharged smoothly through the discharge port, while the coarse particles will be re-entered into the grinding area for further processing until the required fineness is reached.
In addition, the commercial powder grinder is equipped with an advanced control system, which can monitor the machine's operating status in real time and automatically adjust the parameters as needed to ensure the stability and efficiency of the grinding process. Meanwhile, the sealing device inside the machine also effectively prevents the leakage of dust and protects the health and safety of the operators.

Through precise mechanical mechanics design and advanced control technology, the commercial powder grinder achieves efficient and precise grinding of materials, providing high quality powder products for many industries such as pharmaceutical, food, chemical and so on.

Host part: The host is the core part of the mill, mainly composed of frame, air inlet worm shell, shovel knife, grinding roller, grinding ring, cover and motor. The materials are sent to the storage hopper through the elevator, and then fed into the grinding chamber of the host evenly and continuously by the vibrating feeder. In the main machine, the grinding roller and grinding ring are the key parts, which crush the materials through rotation and extrusion.
Transmission device: The transmission device is responsible for driving the rotation of the grinding rolls, which usually consists of the main motor, gear reducer and central shaft. The power of the main motor is decelerated by the gear reducer, which drives the centre shaft and the plum blossom frame fixed on the centre shaft to rotate. The grinding roller assembly articulated and suspended on the plum blossom frame rotates around the centre shaft, while the grinding roller rotates around the grinding roller axis to ensure that the materials are crushed and ground between the grinding roller and the grinding ring.
Powder selecting device: The powder selecting device is used to screen out the powder that meets the requirements according to the particle size. The crushed powder is blown by the airflow of the blower to the separator above the main machine for separation. Particle size is too coarse still fall into the host cavity to regrind, particle size in line with the requirements of the wind flow into the cyclone collector, collected by the discharge pipe discharged that is the finished product. The precision of the powder selecting device directly affects the quality of the finished powder.
Auxiliary equipment: the auxiliary equipment of the mill includes jaw crusher, dustpan elevator, electromagnetic vibrating feeder, electric control cabinet and so on. These equipments are selected flexibly according to the site conditions, and together constitute a complete grinding production line.
Grinding roller cleaning device and suction device: the grinding roller cleaning device is used to clean the residual material on the surface of the grinding roller, preventing the accumulation of material and leading to a decline in grinding efficiency. The suction device discharges the dust and exhaust gas from the mill through negative pressure to keep the working environment clean and safe.

1. High efficiency and energy saving: commercial powder grinder usually adopts advanced grinding technology and high efficiency motors, which can achieve fast and even grinding and reduce energy consumption at the same time.
2. Adjustable fineness: the fineness of the ground powder can be easily adjusted by adjusting the gap between the grinding parts or replacing the sieves of different specifications.
3. Wide range of application: it can be used to prepare all kinds of flour, seasonings, granular drugs, pigments, paints, etc. to meet the needs of different industries.
4. Strong durability: key parts such as grinding discs and wheels are made of wear-resistant materials with long service life and low maintenance cost.
