Calcite is one of the common ore in nature. The grinding of this material can choose Raymond mill. This paper mainly analyzes the characteristics, performance and working principle of calcite Raymond mill.

 First, The basic nature

When the calcite Raymond mill is working, the feed size requirement is 20-30mm. If it exceeds the particle size range, it will increase the powder difficulty of the machine and reduce the production capacity. The materials which will be ground by raymond mill should meet the Mohs hardness of six or less, the humidity is below 6%, and it belongs to non-flammable and explosive ore, so that it can be processed smoothly. The production capacity of Guilin Hengda HD series high efficiency Raymond mill is between 1-60 t/h. The size of the production capacity is related to many factors, such as the nature of the processed materials, the demand for fineness of the finished products, the working conditions of the outside world and the magnitude of the voltage etc will affect the size of the production capacity. In addition, the application fields of calcite Raymond mill mainly include small and medium-sized mines, chemicals, building materials, metallurgy, refractory materials, pharmaceuticals, cement etc.

 Second, The working principle

The working principle of Raymond mill refers to the pulverization process of the material: when working, the material to be pulverized is added into the machine from the feeding hopper on the side of the hood, and the grinding roller device suspended on the main stand of the main machine is rotated vertically. The axis revolves and rotates at the same time. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring, so that the blade shovel the material to the grinding roller and the grinding ring, due to the rolling of the grinding roller to achieve the purpose of crushing materials.

Third, The characteristics

1.Low production cost

Calcite has a small footprint and a strong system. From raw material roughing to conveying to milling and final packaging, it can be used as an independent production system, and the machine’s electrical system uses centralized control to make the powder. The workshop can basically achieve unmanned operation, and the screening rate is as high as 97% compared with other milling equipment.

2.Running stabilityis better

The main gear of the calcite Raymond mill adopts a closed gear box and pulley, the transmission is stable and the operation is reliable, and the important parts of the machine are made of high-quality castings and profiles. The craftsmanship is fine and the rigorous process which ensures the durability of the whole equipment.
