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.

How to choose copper ore beneficiation equipment

Copper ore beneficiation is a process in which copper ore is processed through crushing, grinding, flotation and other processes to extract high-grade copper minerals. In this process, mineral processing equipment is a key link. It can effectively separate metal minerals and waste rocks through physical mineral processing technology. Choosing appropriate mineral processing equipment can improve mineral processing efficiency and ore recovery rate, thereby reducing production costs. Next, let’s briefly analyze the crushing, grinding and flotation equipment needed in the copper ore beneficiation process.

Crushing equipment

Crushing technology is an important front-end process in a copper ore dressing plant. Only by crushing large pieces of copper ore to the required particle size through crushing equipment can the grinding efficiency be improved and high-grade copper minerals extracted.

When selecting crushing equipment, factors such as the hardness and crushing ratio of the ore need to be considered. Although jaw crushers, vertical shaft impact crushers, cone crushers, etc. can be used to crush copper ores, different crushing methods are suitable for copper ores of different properties. , it is necessary to choose the appropriate crushing method according to the actual situation. For example, for harder ores, you can choose to use a jaw crusher, and for medium-hard ores, you can choose to use a cone crusher or vertical shaft impact crusher.

Grinding equipment

Ore grinding technology is to roll, impact and grind the ore particles processed by the crushing equipment under high pressure, and further grind them to achieve the dissociation of copper mineral monomers, thereby facilitating the subsequent mineral processing process. Commonly used grinding equipment includes ball mills, rod mills, etc. When selecting grinding equipment, you also need to consider the hardness of the ore, grinding efficiency and other factors. For harder ores, you need to choose a ball mill that can withstand greater pressure. For heavier ores, you need to choose a ball mill that can withstand greater pressure. For soft or brittle ores, you can choose to use a rod mill; depending on the production capacity, you need to choose different specifications of ball mills or rod mills.

A brief discussion on copper mine supply and demand in 2023

As an important industrial metal, copper is not only widely used in construction, electricity, manufacturing and other fields, but also plays a key role in the global economy. With the gradual recovery of the global economy, the demand for copper is also growing. Let's briefly talk about the market focus of copper mine supply and demand in 2023.

It is understood that in the second half of 2023, global copper mine supply and demand will gradually tighten. On the one hand, the overall new output of copper mines this year is slightly lower than expected, and on the other hand, the expansion of rough refining capacity is accelerating.(stone crusher)

On the mining side, according to data from the International Copper Study Group (ICSG), global copper production is expected to reach 24 million tons in 2023, an increase of about 3% from 2022. The main growth comes from mine output in countries such as Chile and the United States. Increase, but part of the production capacity will not be realized until 2024-2025. Judging from the situation that has been announced so far, due to the decline in ore grade and increased mining difficulty in some major producing countries, it is expected that the growth rate of new investment and expansion of global copper mine production capacity will slow down by 2025. In addition, the decline in production capacity growth in traditional copper-producing areas in South America and the frequent occurrence of interference incidents are also major factors limiting future copper mine output.(Xingaonai group , Stone crusher)
