GX2500 New Pendulum Grinding Machine

GX2500 New Pendulum Grinding Machine

GXThe series of new swing grinding machines are mainly used in chemical industries such as glass, rubber, pesticides, ceramics, paint, phosphate fertilizer, paper, etc. The grinding hardness is below Mohs 7 and the humidity is belowLess than 6% of non flammable and explosive materials. 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 smaller parts by a jaw crusher35mmThe material is 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 on a plum blossom rack5The grinding roller device rotates around the central axis, and the grinding roller swings outward under the action of centrifugal force, thereby causing the grinding roller to press the grinding ring, and the grinding roller rotates around the grinding roller axis at the same time. 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 blown by the airflow of the blower to the classifier above the main machine for screening. Those that are too fine or too coarse still fall into the main machine for regrinding, while those that meet the specifications of 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 (the particle size of the finished product can reach up to)325The 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 chamber, 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 largest in the domestic Raymond machine 8R series, with a production capacity equivalent to that of the LM1500 vertical mill.

2. Small footprint: The equipment takes up less space, while the machines take up less space140Square meters (excluding finished product warehouse and raw material warehouse).

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 efficiency compared to a single cyclone collector10-15%Collection efficiency.

5. High classification accuracy: The classifier adopts a built-in large blade cone turbine classifier, and the finished product particle size is within80-325Adjustments within the scope have improved 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.
