Diabase is a basic epigenetic intrusive rock, its main mineral components are pyroxene and basic plagioclase, and also a small amount of olivine, biotite, quartz, apatite, magnetite, ilmenite, etc. According to the different secondary minerals, it can be further divided into olive diabase, quartz diabase, etc. After the diabase is milled and processed, it can be used for chemical viscose powder, as well as the lining of various equipment and the manufacturing of various parts and joints. With the progress of people's exploration of processing methods, diabase will play a huge role in industrial production and urbanization construction in the future, with broad prospects.

Diabase grinding process

The diabase grinding process is generally divided into diabase coarse powder processing (0-3MM), fine powder processing (20 mesh-400 mesh), and ultra-fine powder processing of diabase (400 mesh-3250 mesh) three types.

Stage 1: Broken
The diabase bulk material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

Stage 2: Grinding
The crushed diabase material is sent to the silo by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the vibrating feeder for grinding.

Raymond mill and YGM high pressure mill are generally used for fine powder processing; CLUM ultra-fine vertical mill and HGM ring roller micro-powder mill are generally used for superfine powder processing; European-style coarse powder mill is used for coarse powder processing.

Stage 3: Grading
The pulverized material is classified by the powder separator, and the unqualified powder is classified by the powder separator and then returned to the main engine for re-grinding.

Stage 4: Gathering Powder
The powder that meets the fineness enters the dust collector through the pipeline with the airflow 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 is uniformly packed by a powder tanker or an automatic baler.

Diabase Ultrafine Vertical Mill

CLUM series ultra-fine vertical mill is a professional equipment in the ultra-fine milling industry that integrates ultra-fine grinding, grading and conveying. Its technical parameters, mechanical properties and finished powder quality can meet the needs of customers.

 

Using the principle of material layer grinding, the material stays in the mill for a short time, with less repeated grinding, less iron content, and high whiteness and clarity of the finished product. The grinding curve of the specially designed roller sleeve and lining plate can be ground to 650 mesh at one time, and can be selected to 3250 mesh through secondary powder selection.

 

Equipped with mechanical and electronic limit devices to avoid damaging shocks and vibrations. Adopt PLC/DCS automatic control of grinding roller pressure control mode, the control is accurate, and no manual operation is required. Equipped with a grinding roller lubrication station, which can not only fully lubricate but also prevent oil leakage.

Using the principle of multi-round powder selection, all rotors are variable frequency speed regulation, and the fineness of the finished product can be achieved within the selected range. The equipment is energy-saving and the technology is reliable. Stable quality and high reproducibility during multi-variety production.

The grinding roller is not in direct contact with the grinding disc, with less wear and longer life. The grinding roller can be turned out for maintenance, which is convenient and quick, and reduces the loss of downtime. Small vibration, low noise, good overall sealing, no dust spillage, clean and environmentally friendly.
