What equipment is used to process limestone? It mainly depends on what is used for production. If it is crushed and used as roadbed stone, crushing equipment is required; if it is to pulverize, Raymond mill or other pulverizers must be used, and specific pulverizing equipment should be matched and selected according to the specific requirements of the particle size of the finished product.

INTRODUCTION OF PRODUCT                                                                                                                                                                                                                         

HCQ reinforced grinding mill.jpg            

 The HCQ series mill is a new type of milling equipment based on the R series Raymond mill. The modified product is suitable for grinding                limestone and other non-flammable and explosive materials with Mohs hardness below 7 and humidity within 6%. The fineness of the                      finished product can be adjusted arbitrarily between 39~180μm (80~400 mesh). HCQ series is an updated product of R-type mill                              (traditional Raymond mill).


  Finished product size: 38-180μm

  Production capacity: 2-13t/h

ADVANTAGES AND FEATURES                                                                                                                                                                                                                       

image.png Use the maintenance-free grinding roller assembly and a new spider-arm, the equipment has higher operating reliability and convenient maintenance.


 A new big blade is used to send a large amount of material between the grinding roller and the grinding ring for grinding.

image.png High output capacity: HCQ series is improved on the basis of the R-type grinding mill, the system is upgraded, the configuration is more reasonable, and the output capacity is higher.

image.png 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 from 80 mesh to 400 mesh.


 Large conveying capacity: The blower adopts a high-pressure centrifugal fan, and the air volume and pressure are increased, which greatly improves the pneumatic conveying capacity.

MILL STRUCTURE                                                                                                                                                                                                                                            

Structure of the HCQ is mainly composed of base, central shaft frame, grinding ring, spider-arm, grinding roller assembly, central shaft, blade holder, blade base assembly, and cover tube. The grinding ring and grinding roller are casted from wear-resistant materials, and their contact surfaces with the materials are all subjected to wear-resistant treatment.

The power unit can adopt two modes: reducer drive and double belt drive. The classifier adopts a forced turbo classifier, and the conveying and feeding system can be selected according to different materials. The collection system can be a closed-circuit collection system with double cyclones and pulse dust collector and an open-circuit system with full pulse collection. The control system can choose automatic control and remote control modes according to customer needs.


WORKING PRINCIPLE & PROCESS                                                                                                                                                                                                                 

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.



1. Crushing of raw materials

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


2. Grinding

The crushed small pieces of limestone 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.

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

2. The pulse dust collector is not a standard configuration and can be selected according to environmental protection requirements.
