Production Line

Grinding mill plant is a stone production line used for grinding stone materials or other ore materials. The whole structure of grinding mill plant include the host machines, plumbing fixtures, air blower, jaw crusher, bucket elevator, hopper, electromagnetic vibrating feeder, distribution cabinets and other components.

Grinding mill production line is unit operations designed to powder or pulverize solid materials into smaller pieces. Grinding is the required process when size reduction of below 5-20 mm is needed; SBM grinding mill series reach the fineness up to 5-1500 micron.

Grinding mill plant is used in metallurgy, building materials, chemicals, mining and other mineral materials of the grinding process can be used for feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, phosphate rock, red iron oxide, quartz sand, cement clinker, activated carbon, clay, coal, gypsum, silicon carbide, refractory materials such as Mohs hardness of 8 below, humidity less than 6% of non-explosive powder processing of mineral materials.

The whole structure consist the host, analysis machine, pipe plant, blower, jaw crusher, bucket elevator, hopper, electromagnetic vibrating feeder, distribution cabinets and other components.

This grinding plant work process: a large block materials are jaw crusher to the desired size, by the elevator the material sent to the bin, and then the feeder will feed evenly into the host of quantitative continuous grinding mill E , after grinding the powder flow fan sub was taken away by the analysis of the grading machine, consistent with the fineness of the powder will flow into the large cyclone collector, were isolated and collected and then discharged through the powder tube shall be finished powder. Flow cyclone collector by the large top of the return air tube blower inhalation.

The machine is a closed loop system, the airflow, and is under negative pressure in the positive cycle of flow. In the grinding room has been ground has some moisture content of materials, grinding mill indoor heat cause changes in the gas flow rate of gas evaporation, and because the pipeline combined with office uptight seal machine and so on, outside the gas is inhaled air volume to increase the revolving air for this by adjusting the balance between the fans and the host duct to achieve the balance of air and gas into the extra bag filter, incorporated into the powder remaining sub-collection of gas down, I was purified exhaust gas.

The motor of crusher drives the belt and the grooved wheel, which connect the eccentric shaft. Through the movement of eccentric shaft, the movable jaw plate moves up and down. When movable jaw plate moves up, the angle between it and toggle plate will be enlarged, so the movable jaw plate will be close to fixed jaw plate. Then, the materials will be pressed and crushed; when movable jaw plate moves down, the angle between it and toggle plate will be reduced, movable jaw plate will moves away from fixed jaw plate due to the tension rod and springs. At this moment, the crushed materials will be discharged at discharge opening. With moving of motor and periodical movement of movable jaw plate, material will be crushed and discharged gradually, so that batch production will be reached.

Main unit of stone mill runs with the central shaft that is driven by a decelerator. The top of the shaft is connected with a quincunx stand, on which a grinding roller is installed to form a swing support. The stone mill's grinding roller not only rotates around the central axle and grinding roller, but also rotates around its own axle due to the friction. There is pallet knife system at bottom of quincunx stand. The pallet knife system is under the grinding roller. With co-rotation of pallet knife and grinding roller, pallet knife will lift the materials into the space between roller and ring to form a material layer. The materials will grinded due to centrifugal force of roller.

The classifier drives the impellers on the tray to rotate through speed adjusting motor, so that powder can be separated. The standard particles will enter cyclone collector. After being separated from the air flow, powder will be collected. Substandard particles will be thrown to the outside wall, to be separated from the air flow. Heavy powder will fall into the grinding chamber to regrind due to self gravity.
