Henan Zhida Hydraulic Coarse Powder Breaker

Product advantages

High grinding efficiency and low operating costs.

A. The coarse powder mill adopts the material layer grinding principle to grind materials, with low energy consumption. The power consumption of the grinding system is 20-30% lower than that of the ball mill, and the energy-saving effect is more significant with the increase of raw material moisture.

B. The grinding body has low wear and high utilization rate. Due to the lack of direct contact between metals during the operation of the coarse powder mill, the wear of its grinding body is small, with a unit product wear of generally 5-10 grams/ton, resulting in minimal metal pollution to the product.

C. The grinding roller sleeve can be flipped over for use, which is beneficial for extending its service life and reducing production costs.

Low construction and investment costs.

The coarse powder mill integrates fine crushing, drying, grinding, powder selection, and transportation, without the need for separate drying, powder selection, lifting, and other equipment. The dust containing gas from the mill can be directly collected by high concentration bag dust collectors or electric dust collectors, with a compact layout that can be arranged outdoors. The building area is about 70% of the ball milling system, and the building space is about 50-60% of the ball milling system. Therefore, the process flow of the coarse powder mill is simple, with a small footprint and space occupation, making the construction cost low.

The product quality is stable and the particle size distribution is uniform.

The material stays in the coarse powder mill for only 2-3 minutes, while it takes 15-20 minutes in the ball mill. So the chemical composition and fineness of the coarse powder mill product can be quickly determined and calibrated, and the quality is stable

Easy to operate and reliable, easy to operate and maintain.

A. Equipped with a rare lubrication station, the grinding roller bearings are lubricated with concentrated circulation of thin oil, ensuring that the bearings work under low temperature and pure oil conditions, extending their service life, and ensuring the continuous and reliable operation of the equipment operating system.

B. Equipped with automatic control devices, it can achieve remote control and is easy to operate.

C. Equipped with a limit mechanism to prevent direct contact between the roller sleeve and the grinding disc liner, it avoids destructive and violent vibrations caused by friction and collision between metals, increasing safety.

The equipment has a large drying capacity and a wide range of ground materials.

The coarse powder mill uses hot air to transport materials, and when grinding materials with high moisture content, the inlet air temperature can be controlled to achieve the required final moisture content of the product. It can dry materials with a moisture content of up to 15% in the coarse powder mill, and has a wide range of applications. Even with dry ball milling, only materials with a moisture content of 3-4% can be dried.

The equipment is environmentally friendly, with low noise, minimal dust, and a clean operating environment.

The coarse powder mill does not have direct contact between the grinding roller and the grinding disc during operation, and there is no metal impact sound of steel balls colliding with each other or the lining plate in the ball mill. Therefore, the noise is low, 20-25 decibels lower than that of the ball mill. In addition, the coarse powder mill adopts a fully sealed system, which operates under negative pressure, with no dust and a clean environment.
