CRUSHER

"When I visited POSCO in Korea from OUTOTEC in Germany in 2011, I saw our roll crusher delivered to the POSCO sintering plant and came to our manufacturing plant. And after the test, I made a contract the next day and delivered a roll cutter to KALAGADI SINTER PLANT in South Africa.
It was the excitement of our technology that approached with impact in that short time. How global is OUTOTEC? Those cunning people said OK at once. The pro knows the real thing, as long as it's durable and guaranteed."

What is Crusher?

It is a mechanical device that crushes ores and other solid raw materials to an appropriate size. It is used for the purpose of reducing the size of material or changing its shape.
Depending on the strength of the gemstone, the type of crusher depends on the size of the target particle.
In addition, a crusher with a more rigid structure is required to achieve high production rates.

CRUSHER is classified into various types according to the size of crushed material.

  • COARSE CRUSHER        : Crusher to crush the largest crusher.

  • SECONDARY CRUSHER : crusher to crush the thin parts

  • PULVERIZER                    : CRUSHER to grind raw material with diameter less than 1cm into 0.07mm size powder

Application

It is widely used in general industries such as mining, road and railway construction, and construction. It is a machine used to crush limestone, granite, iron ore, copper ore to 200 ~ 350mm.

● Steel mill: Raw material crushing equipment, slag processing equipment, limestone crushing equipment, etc.
● Power Plant: Limestone Crushing Plant, Raw Material Crushing Plant
● Chemical facility: Raw material crushing facility
● Aggregate: Primary crushing facility after collecting aggregate
● Limestone Plant: Limestone Crushing Equipment
● Mine: primary crushing facility after rock mining

Advantages

  • Boasts high CAPACITY for the price

  • Simple structure and easy maintenance

  • Shock-absorbing hydraulic system that can block foreign substances such as iron pieces

  • Low noise and dust generation

  • Can meet various customer requirements such as outlet size

  • Can break up more quickly

  • LINER is made of special steel, which has high wear resistance and symmetrical fabrication.

  • Applying roller bearings reduces power and maintenance costs.

How it works

  • The shape of the opening suitable for blunt rubbish

  • wo plates facing each other at a constant angle.

  • One is fixed and the other one is reciprocating with the upper or lower side as a supporting point.

  • The material to be ground is put between plates and compressed and crushed.

HAMMER CRUSHER

Hammer crusher 1

Application

Hammer crusher is not only used in mining, road & railway construction, metallurgy, cement , ceramic industries, but also the most common stone grinding equipment. It is designed to grind soft or medium ore and used as secondary grinders. The moisture content of the raw material is less than 10-15% so that the material is not blocked during the grinding process.

그림1.png

Advantages

  • Strong impact compression crushing movement has high crushing efficiency

  • Simple structure and small size make space utilization easy

  • Easy operation and easy maintenance

  • Low energy consumption

  • Replacing the working parts of the grinder (hammer, grate) is frequent but economical

  • Wear resistance is strong by applying LINER cast with special steel

  • HAMMER is made symmetrically, so if one side wears out, it can be used on the other side, reducing the cost

  • Secondary crusher 

  • Hammering ore from above around the axis of rotation                           and smashing it in the air

  • Double impact due to impact plate

  • Reflected mass is broken by the next hammer

Application

Roll crusher is one of the most widely used grinders in many industries, such as coal, salt, clay, bauxite, limestone and mining. It is designed as a secondary grinder of brittle minerals. It is mainly used in the treatment of wet sticky feeds. Single roll crusher are used to grind frozen or agglomerated materials.

Depending on the size of the ore, there is a flat type and a spike type. The flat roll type is applied when crushing raw materials with small particle size, and the spike type is applied when primary crushing raw materials with large particle size.

Advantages

  • Large capacity processing

  • Simple structure and stable

  • High crushing efficiency and low amount of fine powder

  • Easy maintenance and low maintenance costs

그림1.png

How it works

  • Secondary crusher

  • Used to crush the rock again

  • Size determined by roll perimeter and length

  • Cylindrical rolls made of two steels are fixed on different horizontal axes and adjust the roll spacing according to the size of the aggregate

Application

Impact crusher is used in the transportation infrastructure industry such as mining, highway, railway construction. It is designed as secondary grinder to crush hard gravel such as limestone, calcite, granite, gypsum and concrete.
There is no limit to the location of the grinding work, which is used to grind materials on site, which reduces the cost of transportation.

Advantages

  • Simple operation and easy maintenance

  • Stable performance

  • Effective for saving energy

  • Wear parts (liners) are easy to replace

  • Special wear steel casts LINER and STRIKING BLADE to provide high wear resistance and long replacement cycle

  • Sealing is good and there is no foreign substance inflow

How it works

  • Secondary crusher

  • Impacted and shattered with speedy stones

  • Beat the ore from above with a rod while floating in the air, throwing the material onto the crash board and crushing it

  • Repeat until material breaks down to required size and exits outlet

Application

Rod mill is widely used in mining, chemical industry, powder metallurgy, glass and other grinding industries. It is mainly designed to grind products such as coal and coke evenly. When used for coarse grinding, it has higher throughput than ball mill, and the product's input size is 15 ~ 25mm and 1 ~ 3mm after grinding. Both wet and dry grinding is possible. In order to increase the grinding efficiency and lower the grinding cost, the multi-stage grinding method is adopted. It is also used as the primary fine grinding machine.

Advantages

  • Produce in stable condition by selecting milling time

  • Milling under various conditions depending on the material of the rod inside the cylinder.

  • Installation in a narrow place

  • Maintenance cost is low

How it works

  • Rotary Cylindrical Round Bar Grinders

  • Insert rotate and materials to be crushed

  • Aggregate less than 25mm to less than 5mm

  • Rods are raised or collapsed in rotating drums and crush by force
