INTRODUCTION OF PRODUCT                                                                                                                        

Artificial granite is mainly used for interior walls and floors. In the past, there were many production methods of block stone on the market. The development of artificial stone manufacturing is one of the fundamental ways to comprehensively utilize waste stone. HLMX series superfine artificial stone mill grinder machine is the way to turn waste into treasure. HLMX series superfine artificial stone mill grinder machine adopts dynamic and static combined classifier, and the product fineness can be adjusted between 7μm~45μm. Using a secondary classification system, the fineness can be as high as 3μm. High efficiency, high yield, environmental protection and energy saving are the characteristics of our products.

Finished product size: 3-45 μm

The production capacity is 4-40t/h

ADVANTAGES AND FEATURES                                                                                                                      

Grinding powder high efficiency, energy saving. Specially designed roller sleeve and liner grinding curve, high grinding efficiency; The output of single machine is up to 40t/h. Off-peak electricity is available. Energy saving 30%-50% compared with ordinary mill

Product quality is stable and excellent. The material bed milling principle adopted by the HLMX series mills effectively reduces the repetitive milling rate, and the finished product contains less iron and has high whiteness and purity. In the process of grinding, the added value of the product can be improved by adding a small amount of grinding AIDS without affecting the quality of the finished product.

Easy maintenance and low operating cost. The grinding roller can be turned out of the mill with a hydraulic device to replace the roller sleeve liner. The roller sleeve can be turned over and used. HLMX series mills can be started without load. The grinding roller and the grinding disc liner are made of special materials and have a long service life.

High reliability. The roller limit device is used to avoid the severe vibration caused by the material interruption during the working time of the mill; the new type of roller sealing device is adopted to effectively reduce the oxygen content in the mill and the explosion suppression performance is better.

The comprehensive investment cost is low. Set crushing, drying, grinding, conveying in one of the technological process is simple, the number of equipment is only 50% of the ball mill. It can outdoor layout, and construction cost is low.

Environmental protection. The whole HLMX vertical mill system has low vibration and low noise.

The whole system is sealed and operates under full negative pressure without dust overflow

High degree of automation. Adopt PLC automatic control system, and can realize remote control, reduce labor cost.

MILL STRUCTURE                                                                                                                                            

The complete system of HLMX series superfine calcium carbonate vertical grinding mill is mainly composed of main machine, feeder, classifier, blower, piping device, storage hopper, electric control system, collection system, etc.

WORKING PRINCIPLE                                                                                                                                      

The motor drives the reducer to drive the grinding disc to rotate. The material to be grinded is sent to the center of the rotating grinding disc by the locking air feeding equipment. Under the action of centrifugal force, the material moves to the periphery of the grinding disc and enters the grinding roller table. Under the action of grinding roller pressure, the material is crushed by extrusion, grinding and shearing. 

When iron and other sundries mixed with materials move to the edge of the grinding disc, they cannot be blown by the wind due to their own weight and 

fall into the lower cavity of the mill and are scraped into the slag discharge mouth by the scraper for discharge

SECONDARY CLASSIFYING SYSTEM

The secondary classification system consists of superfine classifier, fan, dust collector, hopper, screw conveyor, pipe and other equipment. The ultrafine classifier is its core equipment. HLMX series superfine vertical mill is equipped with secondary air separation grading system, high powder efficiency, can effectively separate coarse powder and fine powder, separation fineness can be up to 3 μm, can achieve a vertical mill production of different specifications of products, but also fast and stable production of the same fineness of products.

FEATURES OF THE SECONDARY CLASSIFYING SYSTEM

High classification efficiency: the classifier and fan adopt frequency conversion speed regulation control. By adjusting the speed of the classifier and fan impeller, the fineness of finished products with different specifications can be obtained quickly, and the classification efficiency is high.

Classifier: An efficient and energy - saving classifier. Single rotor and multi – rotor can be used, fineness can be adjusted.

Big range of product fineness: Fine particles of vertical grinding materials can be separated, and the fineness range of separation is from 3um to 45um.

ARTIFICIAL GRANITE POWDER PRODUCTION PROCESS                                                                          

1. Crushing of raw materials

Large pieces of marble and calcium carbonate are crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

2. Grinding

The crushed marble and calcium carbonate pieces 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 then returned to the host 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 by the conveying device through the discharge port, and then is packaged by a powder tanker or an automatic baler.
