Mineral powder MP-1 and MP-2

Mineral powder is made by repeatedly grinding carbonate-containing hard mineral rocks into stone powder not exceeding 0.07 mm. The most common are stone powder and dolomite powder. The addition of surfactants or materials containing surfactants can improve the performance of the powder. The main application area of mineral powder is the production of asphalt concrete. It is an aggregate that increases the binding capacity of asphalt.

Types of mineral powder

Mineral powder is mainly divided into two categories: MP-1 and MP-2.

MP-1 mineral powder is made by fine grinding of carbonate rock minerals, and can also be active or inactive mineral powder obtained from asphalt raw materials. It is a mineral powder manufactured in accordance with the requirements of GOST R 52129 2003.

MP-2 mineral powder is a powder obtained from non-carbonate rocks or secondary industrial waste. It is a mineral powder manufactured in accordance with the requirements of GOST 14050-93 and GOST 32761-2014.

Among them, the inactive mineral powder MP-1 is the most popular among users.

The role of mineral powder

Active powder is mainly used as mineral powder for asphalt concrete mixtures. Mainly used in the manufacture of asphalt, converting bulk asphalt into a film. MP-1 powder increases the viscosity, structure, elasticity, strength, uniformity of asphalt quality and the deformation resistance of asphalt concrete roads. In order to build high-quality pavement, materials with improved physical and chemical properties are needed, improving these properties - mineral powder. When it is combined with asphalt, it forms a structured asphalt binder, which helps prevent moisture from entering the asphalt block and increases its strength and deformation resistance.

In addition to the production of asphalt concrete, mineral powder is also widely used in the manufacture of dry building mixtures, concrete and its additives, and roofing materials. In construction, it plays the role of strengthening the foundation, increasing the structural bearing capacity and preventing soil settlement.

Mineral powder grinding equipment

The main equipment for making mineral powder in asphalt concrete is a mineral powder mill, which is used to produce mineral powder.

The MQY series ball mill is one of the high-fine grinding machines widely used in the metal ore crushing and grinding industry. It is a key equipment for fine crushing after material crushing. It is suitable for grinding various hard materials in the mineral processing industry and is an important grinding equipment in the mineral processing industry. The advantages of ball mill are very prominent:

1. Energy saving and low consumption: it adopts double-row spherical roller bearings, which has low running resistance, significant energy saving effect, and can be used in both wet and dry applications.

2. High output and high efficiency: the end cover structure has large inlet and outlet diameters and large processing capacity; the steel ball is reasonably graded and has good crushing effect.

3. Wear-resistant and durable: the wearing parts are all cast with high-quality materials, the casting process is first-class, the wear resistance is good, and the use cost is effectively reduced.

4. Smooth operation: split installation, easy operation; there is no inertial impact during the crushing process, and the equipment runs smoothly.

MQY series ball mill occupies a very high position in the new high-resistant heavy industry grinding equipment. Compared with its competitors, it has very good grinding ability and is very cost-effective.
