The crusher replacement is inevitable, it will be an opportunity for development of crusher. But also give us a wake-up call, to improve the process of crushing machine, the machine service life improve, imminent. The increase in market demand, crushing equipment upgrading, brought crusher export market investment opportunities and increase the crusher enterprise diversification of investment opportunities. So crusher enter to the international market has become an inevitable trend.

It can Apply to the middle and small-broken bits-break materials of mines and iron ore with the Knoop number hardness f=mine 5-16's,such as sums rock, non-ferrous metal ore, granite,limestone, quartzite, sand-rock, cobblestone etc.SBM CS cone crusher with with high-efficiency and single cylinder hydraulic pressure applies to metal mine, metallurgical, chemical , building, cement and sandstone industry etc.

1. orthe like, an upwardly truncated centrally open frusto-conical mantle of a material having the general characteristics of manganese steel with a normally open outer crushing surface and a symmetrically arranged inner surface constructed to define with the crusher head a space for backing material having a normal maximum upper level, the upper edge of the mantle having -a peripheral surface constructed to be engaged by a locking device arranged to apply a downward axial thrust against the mantle to hold it in place on the head, and at least two backing material receiving apertures at the upper end of the mantle inclined to the mantle axis opening through the mantles inner surface well up in the space but below and related to the maximum upper level such that, during pouring, the backing material will not riseabove its maximum upper level. For use in a gyratory crusher.

The method to test the flux can affect the results and these parameters ideally need to be similar. Often the preferred choice is SARM 7B, which is a Merensky Reef sample derived from the South African Bushveld Complex and which is a platinum bearing ore.The real test of a flux is the ability to get a known value on a reference sample.

It was calcined in static air at 850 °C for 3 h to form calcined dolomite.6 g of K2CO3 was dissolved in 50 mL of deionized water, while 10, 15 and 20 wt% K/D loadings require 7.The coarse aggregate of dolomite was ground and sieved to reduce its particle size to less than 24 µm. The paste was later dried in an oven for 24 h at 110 °C and calcined in static air at 850 °C for 3 h using a vacuum furnace.3, 11. The calcined catalyst was kept in an enclosed container to prevent moisture absorption. For the potassium oxide (K2O)-doped dolomite catalysts, it was prepared by liquefying potassium carbonate (K2CO3) in distilled water and pouring 50 g of ground dolomite into the solution. The catalyst was labelled as 5, 10, 15 and 20 wt% K/D.0 and 14.6 g of K2CO3, respectively. The solution was stirred for 90 min to ensure total uniformity. For a 5 wt% K/D K2O loading, 3.

The prevailing minerals are oligoclase (70–90%), K-feldspar (3–5%), quartz (5–20%), muscovite (2–3%), and biotite (1–2%). The quality of the feldspar raw material has been evaluated as Ž85NaCa40 [46].The Ždánov pegmatite feldspar deposit (Figure 1) is situated between Ždánov and Pařezov villages. It consists of a coarse-grained mushroom-shaped pegmatite body hosted in leucocratic quartz diorite near the contact with gabbroid rocks.
