Crushing machine is my factory's main product, sub-standard cone crusher, short head type, generally used for medium and fine crushing on. Standard, generally used for two broken, ie broken. Short head type is generally used for fine crushing, that finally broke. Symons cone crusher has four cavity. Ie special coarse, coarse, medium, fine type. The principle is to look into the selection of particle size and particle size of the discharge decision into Liaoduo large, coarse particle size, choose special coarse or coarse type, and vice versa with medium and fine type. When calculating feed size, with open side by multiplying the maximum feed size 0.85 feed as an alternative basis for the size, and the average size of the product is divided by the maximum feed crushing ratio. Symons cone crusher standard type used for open loop, short head type is used for closed loop.
Recently, the State in order to support the localization trend crusher, crushing machinery to promote - the development of cone crusher, issued a "deep exploration work on the promotion of guidance" to promote China's solid mineral exploration to deep expansion. Showing mining machinery and equipment will be faced with a new round of industry demand, indicating that mining machinery and equipment stocks industry boom is expected to continue rising and continued.
In addition, with the economic development in recent years, become the pillars of heavy industry, the government in order to support the development of the crusher industry to help them smoothly through the financial crisis, the provisions of the Ministry of Finance for large off-highway dump truck and its key components and raw materials import tax policy adjustments. On imported core components of import duties and import VAT to implement front-end retreat for enterprise development and production of new products and innovation capacity building.
From this we can see that the cone crusher impact on the market, how much relief now use mechanized mining industry, particularly in the application of crushing equipment is very important, you can see how the crusher market big.
