Limestone powder processing plant in Mexico

• Limestone usage
  Limestone is a commonly used building material. Limestone can be directly processed into stone, be fired as quicklime and be hydrated lime after adding water. It can also be used as coating material and brick adhesive. Limestone is soft and easily weathered. Its weathering degree varies greatly with the depth of rock mass burial. The rocks with shallow burial depth or on the surface are more weathered. These rocks are flaky, which can be directly used in buildings.
  The deep buried limestone plate is thick, and its compressive strength and durability are ideal, which can be processed into decorative boards needed. According to mine topography and geological conditions, mining usually adopts open-pit mining method with top-down and horizontal steps. The mining process of limestone is generally divided into the following procedures. First, the down hole drilling machine to is used for drilling holes; then, blasting will be taken in medium deep holes. Next, we will use hydraulic excavators to load and send limestone to the crushing station.
  In this process, the role of limestone crushing station can not be ignored. As for the choice of which machine to crush, the different needs of customers should be considered.
  In modern industry, limestone is the main raw material for making cement and calcium carbide. It is an indispensable flux limestone in metallurgical industry. High quality limestone has been widely used in many fields such as paper making, rubber, paint, coating, medicine, cosmetics and so on after grinding by limestone ultra fine grinding mill.
  Mexico customer’s requirements
  Material: limestone;
  Expectant powder fineness: 2000 mesh
  Capacity: 10 t/h
  As you can see, this requirements are relatively challenge. The machine has to meet the high fineness and high capacity simultaneously.
  Applicable Limestone mill
  HGM 125 is chosen as the main equipment in the whole limestone processing plant at this time. HGM 125 can be equipped with the multi-head classifiers.
  The multi-head classifiers which are widely used in our stone pulverizers have many benefits.
  It is suitable for micron dry fine classification. More specifically, the multi-head classifier not only can classify scalable spherical, flake and needle-like particles, but also for the particles of different densities.
  1. The classification fineness can get D97=2-45 micron. The fineness can be adjusted, thus facilitating in changing different fineness products.
  2. The classification efficiency is between 60% and 80%, this especially works when processing good-mobility materials.
  3. And the multi-head classifier is equipped with horizontal classifying turbine unit in high speed and accurate vertex cutting.
  4. A closed loop is guaranteed when it is used with ball mill, vibration mill, Raymond mill and other grinding equipment.
  5. PLC automatic control system, running real-time display, is easy to be operated.
  6. Its negative pressure operation system makes that the dust emissions no more than 40mg/m3, and the noise is lower than 75dB(A) through soundproof measures.
