The DoDoShark 304 Stainless Steel Tooth-Claw Grinder is a mechanical grinding machine constructed from 304 stainless steel components, including the housing, T-type tooth claws, hexagonal teeth, rotating disc, stationary disc, and screen mesh. It is specially designed for food and chemical materials, offering excellent corrosion resistance and rust prevention, and is suitable for both dry and wet processing applications (such as powders and paste-type materials). It is suitable for the fine processing of grains, moisture-containing foods, traditional Chinese medicinal materials, and chemical raw materials.The particle size can be controlled by interchangeable screen meshes, with an adjustable fineness range of 10–150 mesh. The grinder utilizes the high-speed relative motion between the rotating and stationary toothed discs to generate strong shearing, impact, and grinding forces, ensuring efficient material pulverization.
The roller crusher driven by a steam engine first appeared in 1806, with a history of approximately 200 years.
DoDoShark grinder products have undergone over 20 years of development.
DoDoShark’s engineering team includes several experienced engineers with decades of expertise in the grinder industry.
Through continuous innovation, we are revitalizing this traditional industry.
DoDoShark has carried out dozens of product optimizations, particularly in the areas of overall equipment sealing performance, durability, extended service life of screen mesh consumables, gas pipeline sealing reliability, and dust-free workshop processing solutions.
Fully supports self-suction feeding.
Fully supports dust-free production for a clean working environment.
Annual main shaft failure rate below 0.02%
Supports 12-hour continuous operation with a 5x efficiency increase.
Principal machine service life exceeds 10 years
Optimized air ducts and grinding structures increase output by up to 4x at equivalent energy consumption

Grinding Results
Material Processing: Low output, small batch scenarios using bag collection. Processing: Converting fresh, high-moisture raw materials into paste. Liquid Processing: e.g., soybean milk.
Material Processing: High output, continuous operation using cyclone collection. Moist Material Grinding: e.g., processing soaked rice into rice flour. The powder can be delivered to the specified location and height. Generally requires a supplementary dust collection system.
