Limestone Pendulum Roller Grinding Mill delivered to Egypt Customer within 30 Days

This Egypt customer had come to China several times to source limestone pendulum roller grinding mill. But the quality he sourced before is not very good, and cause some trouble during production. This time, after careful and detailed comparison and check, they decided to source from our company.

The material they plan to grind:

1. Raw Material: Calcium carbonate
2. Feeding-in size:20-500mm
3. Fineness: 200mesh; 400mesh
4. Output: 15T/H

We recommend HK1500 limestone pendulum roller grinding mill to this Egypt Customer. And the HK1500 limestone Pendulum Roller Grinding Mill includes the following parts: jaw crusher, elevator, belt feeder, hopper, grinding mill, classifier, reducer, cyclone collector, pipes, dust collector, blower, electric control cabinet.

This working principle in the grinding house: The four rotational rollers hung on the spider arm on the shaft of the main unit go around the rings tightly because of the centrifugal force. The raw material lifted up between the rollers and rings is ground into powder.

Working Principle of Limestone Pendulum Roller Grinding Mill System:

The crushed raw material (less than 20mm or 30mm or 40mm) will be loaded into the elevator and then to the feeding hopper. Conveyor will deliver the crushed raw material into the roller grinding mill grinding chamber. Driven by the reducer and transmission shaft, the spider arm, roller assembly and shovels can rotate. In the grinding mill chamber, the roller on the roller assembly will also move centrifugally and the crushed raw material can be ground into powder between roller and ring.

The ground powder will go up through the classifier with help of high-pressure blower. And the coarse powder that cannot go through the classifier falls down to the grinding chamber, which will be reground between roller and ring. The qualified powder will be collected in the cyclone or in the pulse jet collector.

Improved Performance of Limestone Pendulum Roller Grinding Mill

Roller and Ring are made higher and the shovel is made larger to increase the grinding contact surface and grinding force to increase output.

Improved Reducer: the newly-designed reducer rotation can be adjusted according to customer’s requirement to increase output.

Improved Classifier: the turbine wheel use big blade to increase the fineness control, classifying precision and air volume passing area.

Bigger size cyclone to increase collecting efficiency.

High-pressure blower: air pressure can be increased to make air conveying capacity
