INTRODUCTION OF PRODUCT                                                                                                                                                                                                                        

The main component of white marble is calcium carbonate, which is an important building material and has a very broad market prospect. Calcium carbonate is usually made by pulverizing, classifying and separating white stone with CaCO₃ above 90% by using Raymond mill.

PENDULUM GRINDING MACHINE is a technical update based on the R-type mill. The technical indicators of this product have been greatly improved compared with the R-type mill. It is a new type of high-efficiency and energy-saving mill product. The fineness of the finished product can be adjusted arbitrarily between 22-180μm (80-600 mesh). This product is an updated product of the R-type mill. Among them, the HC1700 large vertical pendulum mill is a large Raymond mill that has been successfully developed early in China. Its output is about 2.5 to 4 times higher than that of similar 5R equipment. It effectively increases the unit output of a single device and reduces the unit. Output and energy consumption are ideal for large-scale milling projects.

Finished product size: 22-180μm

Production capacity: 1-25t/h

ADVANTAGES AND FEATURES                                                                                                                                                                                                                       

New technology, spider-arm and pendulum grinding system. The machine has very small vibration, low noise, stable mechanical  operation and reliable performance.		The processing capacity of materials is larger and the efficiency is  higher. Under the condition that the total power of the R-type mill is  unchanged, the output is increased by more than 40% year-on-year, and the unit power consumption cost is saved by more than 30%.
The remaining air outlet of the mill is equipped with a pulse dust  collector, and its dust collection efficiency reaches 99.9%. All the  positive pressure parts of the main machine are sealed, and a  dust-free processing workshop is basically realized.		Adopting a new sealing structure design, the grinding roller device  can be filled with grease once in 300-500 hours. In addition, there is no need to remove the grinding roller device to replace the grinding  ring, which is more convenient for maintenance.

MILL STRUCTURE & WORKING PRINCIPLE                                                                                                                                                                                                   

HC1700 pendulum mill grinding mill consists of base, center shaft support, grinding ring, spider-arm, roller assembly, center shaft, lifter support, lifter support base, housing and other structures.

WORKING PRINCIPLE

Material is broken by jaw crusher firstly into required size, which are carried by bucket elevator up to storage hopper, again by feeder quantitative into host cavity for grinding, host cavity support in the plum flower rack roller device rotation around the center axis, roller under the action of centrifugal force, horizontal swing outward, so that the roller compaction of ring, roller grinding roller rotation around at the same time.

WHITE MARBLE  POWDER PRODUCTION PROCESS                                                                                                                                                                                

1. Crushing of raw materials

The large pieces of white marble are crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

2. Grinding

The crushed small pieces of white marble are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.

3. Classification

The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding.

4. The collection of finished products

The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected finished powder is sent to the finished product silo through the discharge port by the conveying device, and then is packaged by a powder tanker or an automatic baler.

Note:

1. The Models above are equiped with newly designed spider-arm structure.

2. The capacity is for limestone powder, and specification is just a reference. The actual production depends on these materials being processed.
