china mobile crusher: mobile jaw crusher station is mainly used in metallurgy, chemical industry, building materials, utilities often need to move the material processing operations, especially for highways, railways, hydropower projects and other job mobility stone. Mobile jaw crusher station is a new rock crushing equipment, mainly used in metallurgy, chemical industry, building materials, utilities often need to move the material processing operations, especially for highways, railways, hydropower projects and other job mobility stone Users can employ a variety of configurations depending on the type, size and processing raw materials and finished goods requirements. Mobile jaw crusher station greatly expands the concept field of coarse crushing operation. High-performance crusher, large crushing ratio, powerful crushing pioneer. Car motor and control box integration. With jaw crusher, cone crusher, vertical shaft impact crusher integrated feeder and shaker. Sieve belt conveyor, vibrating screen, crusher integrated vehicle installation. Car installation support, equipment, space efficient and convenient stationed. Traction steering shaft for easy transport and road venues in depth. ball mill principle: ball mill is mainly composed of a cylindrical tube, end caps, bearings and drive ring gear and other components.Cylinder: the inner diameter of 25mm-150mm loaded steel balls or steel bars, called grinding media, the charged amount of the effective volume of the cylinder of 25% - 50%. Cap: cap both ends of the cylinder, the cylinder end by means of screws and flange connected to the end cap has a central bore, called the hollow journal. Bearing: hollow shaft supported on the bearing cylinder can be rotated. Gear ring: fixed on the cylinder. chrome mining:Chromium symbol Cr, silver-white metal, is in the periodic table Ⅵ B family, chromium atomic number 24, atomic weight 51.996, body-centered cubic crystal, common valence of +3, +6, and +2. Chromium-containing minerals is very small, only 0.03% of chromium in the crust, in the form of oxides and ores. Only chrome spinel group minerals with economic value, chromite spinel minerals are chromium collectively. Chromium can be slowly dissolved in dilute hydrochloric acid, sulfuric acid, and a blue solution. Content in the crust is 0.01%, ranking the first 17. Chromium is one of the important strategic materials, because it has a hard, wear-resistant, high temperature resistance, corrosion resistance and other characteristics, in the metallurgical industry, refractory and chemical industries has been widely used. Chromium free state does not exist in nature, mainly containing chromium ore is chromite. rock grinding equipment: after the grinding operations are carried out in a ball mill simplified, the cylinder barrel with the rotation of the abrasive medium be brought to a certain height, and weight of the medium due to the whereabouts of the cylinder body is mounted on the subject medium ore violent impact; partly because of grinding media in the barrel along the cylinder axis of revolution and rotation between the grinding media and the contact area with the cylinder and produces extrusion and grinding of ore stripping force to the ore grated. Ball mill (grinding media) when the band played and the cylinder rotation Jibei rise to a certain height, the ball itself due to gravity, last fall along a certain track. Role in the area of ​​the ball by the two forces: one is the force applied to the ball from the tangential direction of rotation; one for the diameter of the ball relative to said opposite side of the force and the force of the above, this force was the result of the weight of the ball itself caused the downward slide. These two forces, the ball would constitute a pair couple, because the ball is being squeezed in the middle of the cylinder adjacent the ball, so the friction between the balls of varying sizes couple make steel When the ball with the cylinder axis movement for revolution in the region since the fall Paola, on the cylinder body of ore to produce a strong role in regional impact, the broken ore. We can say that in the cylinder body ore mill grinding stripping force is mainly affected by the impact force and effect of extrusion pressure was grated.
