GX2150 New Pendulum Grinding Machine

GX2150 New Pendulum Grinding Machine

GX series new swing typeflour millMainly used for grinding non flammable and explosive materials with a hardness below Mohs 7 and a humidity below 6% in chemical industries such as glass, rubber, pesticides, ceramics, paint, phosphate fertilizers, and papermaking. Such as talc, barite, calcite, limestone, manganese ore, iron ore, chromium ore, quartz, gypsum, bentonite, bauxite, kaolin, etc.

working principle

The material is crushed into materials smaller than 35mm by a jaw crusher, lifted to the storage hopper by a bucket elevator, and then quantitatively fed into the main chamber for grinding by a belt feeder. The main chamber is supported by five plum blossom racksgrinding rollerThe device rotates around the central axis, and the grinding roller swings outward under the action of centrifugal force, thereby pressing the grinding roller tightlyGrinding ringThe grinding roller rotates around its axis simultaneously. The material lifted by the rotating shovel is thrown between the grinding roller and the grinding ring, achieving crushing and grinding due to the rolling of the grinding roller. The ground powder is drummedfanThe airflow is blown to the classifier above the main machine for screening. Those that are too fine or too coarse still fall into the main machine for re grinding, while those that meet the specifications for fineness flow into the double cyclone collector with the wind. After collection, they are discharged through the powder outlet pipe to obtain the finished product (with a particle size of up to 325 mesh). The purified airflow flows into the blower through the pipeline at the upper end of the large cyclone collector, and the air path is circulating. Except for the positive pressure from the blower to the grinding room, the airflow in the other pipelines flows under negative pressure, and the indoor hygiene conditions are good. Due to the moisture contained in the material evaporating into gas during grinding, the gas leaked into the air ducts at the flange joints, feed ports, and other locations in the pipeline increases the air volume in the circulating air path. These increased air volumes are guided to the residual air dust collector through the residual air duct between the blower and the host. The powder carried in with the airflow is collected by the residual air dust collector and discharged into the atmosphere through the bag of the residual air dust collector.

Main technical parameters

Main technical features

1. High output and low energy consumption: This machine is currently the second largest in the domestic Raymond machine 8R series, with a production capacity equivalent to that of the LM1400 vertical mill.

2. Small footprint: The equipment occupies a small area, with the machine occupying 140 square meters (excluding finished product and raw material warehouses).

3. Large conveying capacity: The blower adopts a professional manufacturer's integral high-pressure centrifugal fan, connected to circulating water cooling, easy installation, stable performance improvement, and doubled air pressure, greatly improving the pneumatic conveying capacity.

4. High collection efficiency: The cyclone collector adopts a parallel dual cyclone collector, which improves the collection efficiency by 10-15% compared to a single cyclone.

5. High classification accuracy: The classifier adopts a built-in large blade cone turbine classifier, and the particle size of the finished product can be adjusted freely within 80-325 mesh, which improves the classification accuracy and airflow area.

6. Large material shovel: Using a super large shovel blade to feed the maximum amount of material into the grinding roller and grinding ring for grinding.

7. Energy saving and environmental protection: The exhaust outlet is equipped with a bag filter, which has high collection efficiency and is environmentally friendly and hygienic in the workshop.

8. Improvement of reducer: The reducer adopts German Flender reducer technology, with high output torque, stable and reliable. The bearings are lubricated by force, and the cooling system adopts a water-cooled cooling system. The oil cleaning filter is easy to disassemble and clean.
