Description
1.Application.
Limestone grinding machine has rolling mechanical properties such as rolling, grinding and impact. It is widely used in talc, calcite, calcium carbonate, dolomite, potassium feldspar, bentonite, kaolin, graphite, carbon and other Mohs hardness 7 Ultra-fine pulverization of various non-metallic minerals below the grade and humidity of 6% is a super-fine pulverizing equipment that is truly efficient, energy-saving and especially suitable for deep processing of non-metallic minerals.
2.Limestone grinding machine advantages.
Large crushing ratio and high energy efficiency:
The non-metallic ore pellets having a feed size of <10 mm are processed to a fine powder of <10 μm (the pass rate is 97%), and the fine powder of 3 μm accounts for about 40%, and the specific surface area is large. It has the advantages of high-efficiency and low-cost production of powder by high-speed impact pulverizer, and product fineness close to jet mill.
Dust collection by full pulse dust collection system:
Environmental protection efficiency is up to 99.9%, which effectively guarantees the dust-free operation of the workshop. Complete cleaning: The pulse dust collection system adopts pulse-jet type cleaning method, which uses compressed air to clean each filter bag separately, and the cleaning kinetic energy is higher and more thorough, thus preventing the long-term backlog of powder, and the powder is on the filter bag for a long time. Retention caused by the filter bag.
Forced Turbine Grading System:
The particle size is uniform and fine, and the fineness of the finished product can be easily adjusted between 0.04mm (400 mesh) and 0.005mm (2500 mesh). Different fineness products are better adapted to market demand and improve the competitiveness of enterprises.
Low wear, vibration reduction and compact structure:
The grinding wheel and the grinding ring are made of special wear-resistant steel, and the service life is improved. The main base is made of integral casting structure, which not only ensures structural strength, but also has good shock absorption performance.
