GX1720A New Pendulum Grinding Machine

GX1720A 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: The output is equivalent to the output of 6 4R3216 grinding mills, and the energy consumption is 3/4 of the energy consumption of 6 4R3216 grinding mills.

2. Small footprint: The equipment occupies an area of 150 square meters. On the premise of the same output and particle size, occupying less than one-third of the area of 6 4R3216 units (with a single unit area of 56 square meters) can save factory space and infrastructure investment.

3. Large conveying capacity: The blower adopts a high-pressure centrifugal fan, which increases the air volume and 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 finished particle size can be adjusted freely within 80-400 mesh.

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 conservation and environmental protection:The Yufengkou is equipped with a pulse dust collector, which has a collection efficiency of up to 99.9% and is environmentally friendly and hygienic in the workshop.
