Limestone crushing plant design,Limestone crushing equipment

[shjy2010]

The design of a stone crushing production line is usually decided by several factors:

1) raw materials to be crushed
2) The hardness, percentage of Si, moisture percentage of the raw materials
3) The average size of the raw materials before entering into the crushing system
4）Requested product sizes, percentage of the sizes, and their usage
5) hour capacity of the crushing line
 
For the Limestone crushing production lines: 30-50tph, 50-80tph, 80-120tph, 120-200tph, 200-300tph, 300-400tph, 400-500tph, we here recommend three proposals:
Proposal 1: vibrating feeder +primary jaw crusher +impact crusher +vibrating screen +belt conveying system +control system
Proposal 2: vibrating feeder +primary jaw crusher +fineness jaw crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system
Proposal 3: vibrating feeder +primary jaw crusher +Compound cone crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system
In the above proposals, the main difference is the secondary crusher: using impact crusher (hammer crushing principle), or using fineness jaw crusher(plate pressing principle), or Compound cone crusher(plate pressing principle).
 
If the local market has not request of the stone shape, users prefer to use fineness jaw crusher, or Compound cone crusher as the secondary crusher. Because for high hardness stones, the quick wear parts cost of fineness crusher/cone crusher is lower than that of impact crusher.
 
For jaw crusher and compound cone crusher, the working principle is plate pressing, so the percentage of stones with flaky shape, internal cracks is high.
 
For impact crusher, it has the functions of crushing and shaping, can make very good cubic shape; the stone materials are mainly used for highway, water conservancy, airport, civil construction etc. The market prices of stones made by impact crusher is higher than that by fineness jaw crusher or compound cone crusher; the quick wear parts cost of impact crusher is also high for high hardness stones.
 
If the market has request for the stone shape, and the users want to reduce the quick wear parts cost. Here we recommend firstly use primary jaw crusher + fineness jaw crusher/compound cone crusher as the primary and secondary crushers, take the impact crusher as the tertiary crusher to shaping the stones. This proposal has been adopted by many users, and proved to be workable.

Raymond Mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. It can produce powder from more than 280 kinds of non-flammable and non-explosive mineral materials with Mohs hardness below 7 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc. The final size is between 613micron and 440 micron(0.613mm—0.044mm).
    Raymond Mill  has almost several tens of years history, and the Shanghai BINQ Raymond mill has the same age with the first one all over the world.Currently, the most popular Raymond mill in the leading position are on the basis of Newell Company and occupies 70% market share. Raymond mill’s production and the development has closely related to the development of scrap industry.
This series raymond mill adopts domestic and foreign advanced structure of the same plants; its structure is getting perfect day by day. For low consumption, low investment, environment friendly, small occupation area, and more efficient than ball mill. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. So if roller and ring are damaged, it will not affect the fineness of final products. Life of tear and wear parts will be long. he set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.
Vertical roller mill is one advanced mill, adopting top technology domesic and abroad, and based on many years’ mill experiences. It can crush, dry, grind, and classify the materials.

The BINQ Symons Cone Crusher is a high-performance models optimized and improved on the basis of Symons Cone Crusher. the symons cone crusher is widely used for secondary and fine crushing in the fields of mining, building materials, metallurgies and so on. The Symons Cone Crusher  can crush materials with middle and high hardness, such as, metal ore, basalt, granite, limestone, cobblestone, sandstone and so on.
S Series Cone Crusher Structure Features
1. Multi-crushing chamber: Symons Cone Crusher  has a special design with three types of chambers; as to the differnet situation ,users can choose the crushing chamber which can ensure high effiency,evenly size ,long service life ,and the evenly abrasion of the mantle.
2. Dry oil seals dust :Unique structure to seal dust ,the reliable sealing extended the lubricants’repalcement cycle and the service life of the spare parts .
3. High crusher power:The key components made of the special materials speed up the crushing cavity’s working process.
4. High production: Long crush arms and the long compact distance reduce the load of the sliding berarings ,gears and rack.
Vertical roller mill:Specialized for the high production of superfine pyrophyllite powder making in glass fiber industry
Specialized for the high production of gangue powder making in coal industry
Specialized for the high production of various of chemical raw material powder making in the chemical industry.
It is a necessary equipment for the high production of mineral powder in the non-mental mine industry and large scale powder making in many other industries.
Large scale power mill designed specially to solve problems of low capacity and high consumption of industry mills
