The DoDoShark Cast Iron Claw-Type Grinder is a robust mechanical grinding machine featuring a high-strength cast iron housing, forged T-type tooth claws, and (on selected models) a high-hardness alloy stationary toothed disc for enhanced durability and performance. It is specially designed for dry grinding of medium-to-low hardness and fibrous materials. It is suitable for fine processing of grains, Chinese herbal medicines, feed ingredients, and chemical raw materials. Grinding fineness is controlled by interchangeable screens, ranging from 10 to 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.
The principal machine and fan are made of thickened cast iron, with a service life of over 10 years
Supports 12 hours of continuous operation without shutdown
Annual main shaft failure rate below 0.02% (less than 2 units per 10,000)
With optimized air duct and tooth disc design, the output can be increased by up to 2 times under the same energy consumption.
Supports multiple feeding methods, including self-suction, bucket elevator, and screw conveyor feeding.
Corn, soybean meal, wheat, fish bones, etc.
Beans, mixed grains, dried tubers,etc.
Pepper, chili, Sichuan pepper, dried tangerine peel, cumin, fennel, cinnamon, etc.
Notoginseng, Astragalus, Andrographis paniculata, pearl, and various medicinal herbs.
Talc powder, rare earth materials, clay, bamboo charcoal, gypsum, calcium metal, and other low-hardness minerals.
