INTRODUCTION OF PRODUCT                                                                                                                                                                                                                         

Lime is an important mineral resource with high utilization value. By subdividing lime, it can be divided into quicklime and hydrated lime. The processing technology of different types of lime is very different, and the utilization value will also be different. For lime manufacturers, choosing a production line equipment that can achieve efficient use of lime is an important measure to improve market and economic benefits.

The HCQ LIME STONE POWDER PULVERIZER IN THERMAL POWER PLANT is a new type of milling equipment based on the R series pendulum mill. This product is suitable for grinding dolomite 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 between 39~180μm (80~400 mesh). HCQ lime pulverizer is an updated product of R-type mill.

Finished product size: 38-180μm

Production capacity: 2-13t/h

ADVANTAGES AND FEATURES                                                                                                                                                                                                                       

 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.

 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.

 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 pulverizer in thermal power plant 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                                                                                                                                                                                                                                       

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.

QUICKLIME POWDER PRODUCTION PROCESS                                                                                                                                                                                           

1. Crushing of raw materials

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

2. Grinding

The crushed small pieces of quicklimes 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 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.
