Characteristics of pulverized coal particles are made of different sizes, irregularly shaped powder particles composed generally pulverized coal particle diameter range 0-1000um, most of the particles 20-50um; pulverized combustible substances, dangerous goods B fire, dust with explosive, fire point between 300 ℃ ~ 500 ℃, the lower explosive limit concentration 34 g / m ~ 47g / m (average dust particle size: 5μm ~ 10μm).
Pulverized Coal material crushing and grinding Processing Plants used the machines as follows:
Primary crusher: jaw crusher,PEW Series jaw crusher
Secondary crushing machine: Impact crusher and hydraulic cone crusher
Mill: MTW Series Trapezium Grinding Mill
Accessories: Belt conveyors
Pulverized Coal production line process Intruduction:
- dressing, large pieces of material from the crusher as primary crusher, a common primary crusher jaw crusher, the European version of the jaw crusher.
- The material after primary crushing, turn-by-crusher or hydraulic cone crusher for secondary crusher.
- After the material as well as the secondary crusher after the transfer of materials have to meet the requirements for grinding mill grinding, substandard materials are wandering around twelve conveyor belt crushing process until there is compliance with the requirements of another mill They were milling.
- The final production of the finished material, by the appropriate local party store custody.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
