The structure of the rod mill
The rod mill is the center drive center discharge, both ends of the mill by the main bearings supporting four Warehouse. Diaphragm plate mill built the cylinder separated for four positions,quartz grinding machine first positions filled with grinding media steel bars, so called rod mill
1 - feeding device; 2 - cone; - main bearings; - imported hollow shaft; - grinding end caps; 6 - Cover the liner; - grinding cylinder; 8 - a position lining; 9 - a warehouse compartment plate; 10 - two positions liner; 11 - two positions compartment board; 12 - three positions liner; 13 - three positions diaphragm plate; 14 - to block the ball circle; 15 - four positions liner ; 16 - backgauge circles; 17 - export grate; 18 - spiral sleeve; 19 - Export hollow shaft; 20 - discharging device; 21 - discharge casing; 22 - reducer; 23 - motor; 24 - lubrication devices; 25 - auxiliary motor; 26 - lubricating device baseball grinding wet raw mill.
When the rotary steel bars with mill upgrade and whereabouts, the brunt of the stick between the larger particle size materials, and fine-grained material is less susceptible to shock. Therefore, the materials from warehouse uniform particle size, to improve the grinding conditions of the second compartment. Baseball mill closed, open system, but the steel bars has the effect of the closed system of classification. Steel bars for better adaptability to the raw materials of high hardness, particle size of material into the mill may be appropriate to relax, but to replace the steel bar as the ball convenience.
The mill grinding body is the main motor power 800kW of 23, to 19.2r/min speed reducer 22,sand crushing plant the discharge casing 21 and export hollow shaft 19 driven rotation. Grinding cylinder body equipped with every other board positions 9, 11 and 13, the cylinder is divided into four chambers. Transition position double-diaphragm plate between the two positions, two, three positions three, four positions are based on
Cylinder of a warehouse built by the production of high-manganese steel corrugated liner is installed within the two positions are ladder liner 10, three or four positions within the inlay puzzle produced by alloy white cast iron corrugated liner (corrugated liner) 12 and 15. Shop between the cylinder and liner layer 3mm thick plywood, and some to pad a thin rubber sheet, and the other in order to prevent materials or broken grinding media to enter the the scour cylinder between the cylinder and liner, three, four positions small ripple between the liner and cylinder filling of asbestos cement.
Four warehouses built in order to improve mill grinding efficiency, high-manganese steel system block off circle 14 and the backgauge circle 16, with bolts in the cylinder. Material at the exit of four positions with export grate 17, it is from the inside, the outer export grate composition, through the grate plate frame bolts on the end cap of the mill exports.
The end cap of the mill is welded end caps and welded into one,silica sand processing plant and the cylinder end cap inner wall of the bolt end cap liner to protect the end caps are not worn. Filling the interstitial space between the cover and liner with cement mortar.
Mill into export hollow shaft connected together with bolts and mill end caps. Imports of hollow shaft 4 built-in cone. Export hollow shaft 19 contains a spiral sleeve 18, the main protective hollow shaft without material wear, while also facilitating the flow of materials. At the gap between the bushing and hollow shaft filling with cement mortar. Cylinder at both ends of the hollow shaft mounted on two sets of main bearings 3. The main bearings with lubrication device 26, for circulating lubrication.
Feed mill material from the feed device, and by the import hollow shaft into the grinding cylinder body, by the impact of various positions in the grinding media and grinding through the discharge grate 17, through the export of the hollow shaft 19,roll crusher manufacturer the discharge casing (also known as Drive over) 21 to the discharging device 20 within the cylindrical sieve, sieve analysis, the qualified products by the conveyor into the material library.
