20 types of mining machinery – one article Understand the working principle
Mining machinery 1: Magnetic separator
The magnetic separator is made of ferrite material or composited with rare earth magnet steel, and the average magnetic induction intensity of the cylinder surface is 100-600mT. According to user needs, it can provide magnetic separation with different surface strengths such as downstream, semi-countercurrent, and countercurrent. It has the characteristics of simple structure, large processing capacity, convenient operation, and easy maintenance.
Mining machinery 2:High gradient magnetic separator
The high gradient magnetic separator is a kind of equipment specially designed for the selection of weak magnetic ores. It is divided into two types: dry selection strong magnetic machine and water selection strong magnetic machine. The general weak magnetic ores mainly include limonite, hematite, manganese ore, and paragenetic ore (multiple ores coexist). This weak magnetic ore is mainly composed of ferric oxide. If you want to extract ferric oxide, you need to use high-strength magnetic equipment for selection. It has the advantages of large enrichment ratio, strong adaptability to feed material degree, concentration and grade fluctuations, reliable operation, and convenient operation and maintenance.
Mining machinery 3: Jig machine
Jig machine is an energy-saving gravity separation equipment developed and improved on the basis of traditional jig machine according to the stratification law of jig bed theory. It adopts conical slide valve, reliable operation, low energy consumption, and can meet the separation needs of different media.
Mining machinery4: Shaker
Shaker is a widely used gravity separation equipment. Shaker separation uses the mechanical shaking and water flow to separate the ore particles according to density. Its characteristics are obvious banding, convenient sectioning and access.
Mining machinery 5:Fixed hanging iron remover
The hanging electromagnetic iron remover is a DC excitation iron removal device, which is used to hang above the conveyor belt to remove the stray iron in the moving bulk material. It has the characteristics of maintenance-free, strong magnetic force, long life, simple installation, easy use, and reliable operation.
Mining machinery 6:Ore washer
The ore washer feeds aggregates containing mud and stone powder from the feed port into the rotating drum, where they are continuously lifted and thrown down by the cleaning drum and washed and rinsed by the forward or reverse flushing water. The cleaned aggregates are screened and dehydrated by the drum screen at the discharge end and then discharged. It has the characteristics of long service life and long-term maintenance-free.
Mining machinery 7: Wheel sand washer
The wheel sand washer is driven by an electric motor and a reducer, which drives the impeller in the water tank to rotate continuously in the water tank, thereby stirring, turning, and washing the sand or slag particles in the water tank. Finally, the material is dehydrated in the impeller and discharged. It has the characteristics of fully enclosed oil bath transmission device, adjustable overflow weir plate, large disposal capacity, low power loss, and simple maintenance.
Mining machinery 8: Spiral sand washer
When the spiral sand washer is working, sand and gravel enter the washing tank from the feed tank to remove impurities covering the surface of sand and gravel, and are discharged from the overflow washing tank to complete the cleaning process. It has a wide range of applications and is suitable for industries such as metallurgy, building materials, and hydropower. It can clean, grade, remove impurities, and wash construction sand, road sand, and gravel sandstone.
Mining machinery 9: Bag Dust Collector
When the bag dust collector passes the dust-containing gas material through the filter material, the dust is retained on its surface, and the clean air is discharged through the gaps in the filter material. It has the characteristics of strong adaptability, easy material recycling, and reduced pollution.
Mining machinery 10: Wet Dust Collector
The wet dust collector is commonly known as the “water dust collector”. It makes the dust-containing gas and liquid in close contact, using the inertial collision of water droplets and particles or the full mixing of water and dust. It is characterized by being able to be used in high temperature, dry, flammable and explosive, and harmful gases, and has high dust removal efficiency.
Mining machinery 11: Pulse dust collector
The pulse bag dust collector, driven by the fan power, forms a negative pressure environment inside the dust collector, the dust collection pipeline and the dust collection hood, so that the dust at the dust point enters the dust collector under the action of pressure difference, and the airflow is filtered through the dust collection filter bag. The dust is trapped on the bag surface. The pulse signal is input to the pulse valve regularly through the controller.
The high-pressure wind of the compressed gas will blow the dust adhering to the filter bag surface down and collect it in the ash hopper, thereby achieving the purpose of collecting dust. The treated clean gas is discharged from the chimney through the dust collection fan. It is suitable for the purification of dust-containing gas and the recovery of materials in metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry.
Mining machinery 12: Cyclone dust collector
When the dust-containing airflow enters the dust collector from the tangential inlet, the airflow rotates in the dust collector. The dust particles in the airflow move to the outer wall under the action of centrifugal force, reach the wall surface, and fall into the ash hopper along the wall under the action of airflow and gravity to achieve the purpose of separation. It has the characteristics of simple structure, easy manufacturing and installation, convenient maintenance and management, low cost and operation cost, and small footprint.
Mining machinery 13: Hydrocyclone
Use strong centrifugal force to separate the mixture under high-speed rotation. It has simple structure, no moving parts, easy operation and supervision, small size and large processing capacity, and is suitable for processing finer materials.
Mining machinery 14: Crushing production line
Mining machinery 15: Drum dryer
The drum dryer dries the wet material and then sends it out through a belt conveyor or a screw conveyor at the discharge end. If the dust content of the tail gas needs to be further reduced, it should also be discharged after passing through a bag filter or a wet dust collector. It has the advantages of reliable operation, large operational flexibility, strong adaptability, and large processing capacity.
Mining machinery 16: Drying production line
Mining machinery 17: Classification principle
The spiral classifier uses the principle that the solid particles have different sizes and specific gravities, and therefore have different settling speeds in the liquid. Fine mineral particles float in the water and overflow, and coarse mineral particles sink to the bottom of the tank. A grading device that is pushed to the upper part by a spiral to perform mechanical grading. It can filter the powder ground in the mill, then use the spiral blades to rotate the coarse material into the mill feed port, and discharge the filtered fine material from the overflow pipe.
Mining machinery 18: Double spiral ore washer
The double spiral ore washer adopts a central structure, with spiral blades installed on the central shaft and connected to the central shaft by a reducer for operation. It is a device for mechanical grading based on the principle that the specific gravity of solid particles is different and therefore the sedimentation speed in the liquid is different. It can handle the dirt and ash on the material and wash it into clean materials. This machine has the advantages of simple structure, easy maintenance and high washing efficiency.
Mining machinery 19: Cylinder ore washer
Cylinder ore washer equipment is widely used for washing materials in sand and gravel fields, mines, building materials, transportation, chemical industry, water conservancy and hydropower, concrete mixing stations and other industries.
Mining machinery 20: Color sorter
It is a device that uses photoelectric principles to detect and separate individuals with abnormal color or infected with pests and foreign impurities from a large number of bulk products. The system has simple structure, easy assembly and low failure rate.
