Material introduction

Graphite is an allotrope of carbon, which is gray-black, opaque solid, and graphite powder can be obtained after grinding. Graphite powder is soft, black-gray, greasy, chemically stable at room temperature, insoluble in water, dilute acid, dilute alkali and organic solvents; graphite powder has high-quality high temperature resistance, good electrical and thermal conductivity, plasticity, lubrication It can be used in the manufacturing process of refractory, electrical conductivity, metallurgy and other fields.

Graphite grinding process

Graphite grinding process is generally divided into three types: graphite coarse powder processing (0-3MM), fine powder processing (20 mesh-400 mesh), and graphite ultra-fine powder deep processing (400 mesh-3250 mesh).

Phase 1: Broken

The bulk graphite material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

Second Stage: Grinding

The crushed graphite small pieces are sent to the silo by the elevator, and then evenly and quantitatively sent to the grinding chamber of the mill by the vibrating feeder for grinding.
Generally, CLRM Raymond mill and YGM high-pressure mill are used for fine powder processing; CLUM ultra-fine vertical mill and HGM ring roller micro-powder mill are generally used for ultra-fine powder processing; European-style coarse powder mill is used for coarse powder processing.

Stage Three: Grading

The ground materials are classified by the powder classifier, and the unqualified powder is classified by the classifier and returned to the main machine for re-grinding.

The fourth stage: collecting powder

The fineness powder enters the dust collector with the airflow through the pipeline for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then uniformly packed by a powder tanker or an automatic baler.

CLRM Graphite Raymond Mill

In addition to the grinding of graphite, the graphite mill can also be used for barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement , phosphate rock, gypsum, glass, insulation materials and other non-flammable and explosive minerals, chemicals, construction and other industries with a Mohs hardness not greater than 9.3 and a humidity below 6% for high-fine powder processing of more than 280 materials, The particle size of the finished product can be adjusted arbitrarily within the range of 80-325 mesh, and some materials can reach 600 mesh.

Working principle of phosphate rock mill

When the graphite mill is working, the materials to be crushed are fed into the machine from the hopper on the side of the machine casing, relying on the grinding roller device suspended on the plum blossom frame of the main machine, it revolves around the vertical axis, and at the same time it rotates itself, due to the rotation Under the action of centrifugal force, the grinding roller swings outwards and presses tightly on the grinding ring, so that the spatula scoops up the material and sends it between the grinding roller and the grinding ring, and the purpose of crushing the material is achieved due to the rolling and rolling of the grinding roller.

Graphite Mill Production Line

Graphite pulverizer is mainly composed of main machine, blower, ultra-fine analysis machine, finished product cyclone powder accumulator, bag dust collector and connecting air duct pipe, etc. It is used for material grinding work. In addition, according to the needs of users, it can be equipped with auxiliary equipment such as bucket elevators, storage bins, electric control cabinets, powder feeders, and jaw crushers, which are used in various production lines.

1. The graphite mill has good wear resistance, reliable operation and high efficiency.

2. The graphite mill adopts a high-pressure spring, and its pressure can reach about 1400KG.

3. The overlapping multi-pole sealed grinding device of the graphite mill has good sealing performance and the dust removal effect fully meets the national dust emission standards.

4. In the case of the same output and fineness, the price of graphite mill is only one-eighth of that of jet mill, and the scope of application is also larger.
