The ferrochrome is used as additive in steel in order to produce various special steels with high strength, corrosion resistance, wear resistance, thermostability and oxidation-resistivity. Combining with cobalt, nickel, tungsten and some other elements, chrome metal is mainly used to smelt special alloy. In metallurgy, chromite is mainly used to produce ferrochrome and chrome metal. Besides, chromite also has widely applications in glass, ceramics and fireproof material and some other fields.Chromite is the necessary mineral resource for developing metallurgy, national defense, chemical and some other industries.

Even in the same lubrication state, the friction force is not the same, due to different lubrication oil type and characteristics. The experiment proved that, the friction coefficient and friction force is in decreasing along with the half dry friction, boundary friction, semiliquid friction, fluid friction order.Clean up the wearing parts of the machine, then cover the lubrication oil on the surface of them, it can change the friction state, and decrease the friction force of them.

As we know, the temperature in winter is quite low, which will greatly reduce the service life of crushers or even make the oil and water in crushers frozen, so operators should make overall check and maintenance about crushers in winter, making sure crushers do not produce any problems caused by temperature change.If we want the crushers still can work without load at 50 degrees below zero, we need firstly to know the effect of temperature change on crushers.

3) is heterogeneous and well compacted, see Figure 1.0 mm. Granite aggregate (grain size index CU = 7.1 and CC = 2.The crushed granite aggregate (GA) with fractions of 0–4 mm was used. The background is the upper and lower curves determined in accordance with the PN-EN 12620+PN-B-06265 standard for natural aggregate with fraction up to 4.

These sheets are chemically inert, flexible, elastic, reflective and are transparent to opaque [3]. These layers can be split or delaminated into large thin sheets. It has widespread industrial applications due to its physical properties such as color, density, particle shape, size, layered structure and reflection index [1,2].Mica is a plate-like structured and complex hydroaluminum silicate mineral with unique physical and chemical properties. Muscovite mica (ideally (KAl2(AlSi3O10)·(OH)2)) has also a plate-like mineral crystalline structure formed in layers.
