Large capacity vertical Raymond grinding limestone power processed plant

What equipment is used to process limestone? The specific grinding equipment needs to be matched and selected according to the specific requirements of the particle size of the finished product. The ore crushing and grinding process is the most critical process of mineral processing in the mine, and the crushing and grinding process is also one of the important technologies for mineral processing.

INTRODUCTION OF PRODUCT                                                                                                                                                                                                                         

Large capacity vertical Raymond grinding limestone power processed plant. Considering the properties of limestone raw materials, the material strength of limestone itself is not very high, and the hardness is medium, so jaw crushing can be used for the initial breaking link. For the crushed limestone powder processing, different types of limestone mills can be selected according to the requirements of the fineness of the finished product. Guilin Hongcheng specializes in providing a complete set of solutions for limestone milling, and is a professional limestone milling solution expert. HC vertical pendulum mill is mainly suitable for producing 80-400 mesh limestone powder. The fineness can be adjusted between 38-180μm. HC large pendulum mill, the capacity can reach 90T/h.


ADVANTAGES AND FEATURES                                                                                                                                                                                                                       

image.pngNew type of spide-arm featured in compact structure. It can be maintained

without disassembly, which save the maintenance time.


Adopt maintenance-free oil seal technology, screw seal and skeleton oil sealmulti-layer barrier, limited to prevent dust from entering, can achieve add lubri-cating oil per 500~800 hours, reduce the maintenance cost.


Unique high chromium alloy material technology, the use time is nearly 3

times of the industry standard.


Forced turbine classification technology. The particle size of finished products can be adjusted infinitely between 80~400 mesh.


Off-line pulse dust collection system, dust collection rate up to 99.9%.

MILL STRUCTURE & WORKING PRINCIPLE                                                                                                                                                                                                   

HC grinding mill consists of mill system, classifying system, screening, collecting system and other components. The mill system adopts the structure of integral casting base, which can be used as shock absorbing foundation. The classifying system adopts mandatory turbine classifier structure and the collecting system adopts pulse collection.


Power processing system technological process: raw material will be transport to semi-open shed by special vehicle, and then be shoveled into the crusher to be crushed into particles smaller than 40mm. The material particles will be raised to the storage hopper by the elevator and then be evenly sent to the main mill for grinding by feeder. The qualified fine powder will be classified and blew to the pulse dust collector as product and finally discharged from the dust collector. The product will be transported to powder storage. HC super large grinding mill has really high capacity so the product cannot be packed by hand-filling, the packing job is supposed to be done after the power be sent to storage tank.

LIMESTONE POWDER PRODUCTION PROCESS                                                                                                                                                                                           

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.
