Structural Composition
Crushing System: The core is a combined structure of a movable gear disc and a fixed gear disc. The movable gear disc rotates at a high speed with the main shaft (rotational speed 3800r/min) and forms a staggered tooth set with the fixed gear disc, achieving material crushing through impact and shearing actions. The crushing chamber is made of all stainless steel, with precision polishing treatment on both inner and outer walls, no dead corners, easy to clean, and compliant with GMP standards. Some models are equipped with a water circulation cooling device, which can avoid the damage to heat-sensitive materials (such as pharmaceuticals, food) caused by high temperatures during the crushing process.
Classification and Collection System: The bottom of the crushing chamber is equipped with a replaceable screen. The fineness of the finished product is controlled by selecting screens with different apertures of 60-120 meshes. Coarse materials will continue to be crushed in the crushing chamber until they meet the particle size requirements. It is equipped with a collection bag and a material collection box. The finished product automatically enters the collection bag through centrifugal force to achieve rapid collection.
Dust Removal System: Composed of a dust suction fan (power 0.75-1.1kw), a dust suction box and a bag filter, it can efficiently filter the dust generated during the crushing process, avoid flying pollution, and improve the material recovery rate.
Transmission and Control System: The main motor power is 5.5kw (7.5kw for some models), which drives the main shaft to drive the movable gear disc to operate. The electric control box can adjust the feeding speed and motor load to prevent stuffy cars. Some derivative models (such as ZCW-30B) are equipped with touch screen intelligent control, supporting low-temperature refrigeration (-25℃ to 0℃) and precise parameter setting.
Working Principle
Feeding stage: Brittle materials with a particle size of ≤10mm enter the crushing chamber through the feed hopper, and quantitative feeding is achieved by means of slight vibration of the equipment.
Crushing stage: The high-speed rotating movable gear disc and the fixed gear disc form a strong shearing and impact area. The materials are crushed by mechanical force between the gear sets, and the mutual collision between materials further improves the crushing effect.
Classification and collection stage: Materials that meet the fineness requirements enter the collection bag through the screen, while coarse materials remain in the crushing chamber for further processing; dust is filtered and collected by the dust suction system to achieve dust-free operation.

Features
Strong compliance: All parts in contact with materials are made of stainless steel, and the fully enclosed structure prevents cross-contamination, meeting the GMP standards of the pharmaceutical and food industries.
Flexible and adjustable: The crushing fineness can be quickly adjusted by replacing the screen to adapt to the needs of different industries; some models support dry, wet crushing and low-temperature operations, and can handle fibrous and high-toughness materials (such as Chinese medicinal materials and spore powder).
Efficient and energy-saving: The crushing efficiency is over 99%, with a maximum output of 300kg per hour. The motor load is controllable, and the operating cost is low.
Easy maintenance: The structure is simple with low failure rate, there is no material accumulation in the crushing chamber, and cleaning and screen replacement are convenient.
Application fields
Pharmaceutical industry: Used for crushing traditional Chinese medicinal materials (such as Ganoderma lucidum, hawthorn) and pharmaceutical excipients, as well as cell wall breaking (such as spore powder with a wall-breaking rate ≥ 95%), to ensure the release of active ingredients.
Food industry: Processes brittle materials such as powdered sugar, essence, and nuts, avoiding high-temperature damage to nutrients and meeting food safety standards.
Chemical and pesticide industry: Crushes pigments, additives, pesticide technical materials, etc., to ensure the uniformity and stability of materials.
Scientific research field: Small models (such as the laboratory-grade ZCW-30B) are suitable for ultra-fine crushing of precious medicinal materials and biological samples, supporting multi-variety and small-batch experiments.
