What are the Crusher Types?

Primary Impact Crusher

It is a crusher with a very high cubic ratio, which is generally used as a primary crusher, which enables large-sized stone types with medium hardness and low abrasiveness to be reduced in the primary impact section. By adjusting the gap between the pendulum and the pallet, the desired size of the product is obtained.

Reduced products can be obtained in smaller sizes when breaking materials with less abrasiveness and not very hard. These crushers are preferred in the primary crushing stage in crushing and screening plants. According to the design of the facility, they can be produced as mobile, fixed steel feet, fixed concrete feet, and fixed skid chassis.
The primary impact crusher consists of three basic parts. Rotor, fixed lower body and retractable upper body. The upper body is opened by turning around a joint fixed to the lower body with the help of the hydraulic mechanism, enough to expose the rotor and internal parts.
The lower body is fixed to the main chassis. The task of the lower body is to carry the rotor. In addition, the upper body, the inlet chute and the maintenance crane mechanism are mounted on the lower body.

There are two pendulum systems on the upper body that allow adjusting the product dimensions and the adjustment mechanisms connected to them. In addition, the rotor side is covered with breaking plates.

Pendulums are positioned to enable a two-stage crushing process. It is connected to the body with a fixed joint from its upper edges and its lower edges are held with adjustment studs.

The rotor is driven to generate a high amount of kinetic energy in the pallets. With this energy, very strong blows are applied to the material. With the impact of the impact, the material hits the crushing plates and the crushing process is performed. The material is reduced so that it can pass through the narrowest distance between the crushing plates connected to the first pendulum system and the rotor pallets. In this way, the material, which is reduced to a certain size in the first stage, passes to the second stage. Here, too, the same processes are repeated and the resulting product passes into the discharge chute.

Pendulum

There are two separate pendulum systems, upper and lower. In the first stage of the crushing process, the upper pendulum takes charge, and in the second stage, the lower pendulum takes charge. According to the desired product size, the pendulum opening can be adjusted easily and safely by means of hydraulic cylinders.

Palette

It has high resistance to breakage. It is rigidly mounted to the rotor body with wedges. On the one hand, it is fixed with counter pallet holders.

linings

It is made of hardox or alloy steel casting, which is very resistant to wear. They are produced in pieces, allowing them to be changed easily and are fixed to the body with the help of bolts.

Body

It has a long life, high strength and welded design. It has two basic parts called the lower and upper body. The lower body is fixed, the upper body can be opened and closed. This on-off operation is performed with hydraulic cylinders. It uses inspection caps on both sides of the body to control the adjustment process and monitor the condition of the wear parts.

Secondary Impact Crusher

It is used as a 2nd crusher in the facility.
Secondary Impact Crushers can reduce medium and high hardness materials such as limestone, dolomite, granite and basalt to asphalt and concrete aggregate size. Large size material from primary crusher can be fed directly. It provides high reduction ratio. According to the design of the facility, they can be produced as mobile, fixed steel feet, fixed concrete feet, fixed skid chassis, pre-screened or pre-fed.

It consists of three main parts. Rotor, fixed lower body and retractable upper body. The upper body is opened by turning around a joint fixed to the lower body with the help of the hydraulic mechanism, enough to expose the rotor and internal parts.
As a result of the movement given to the rotor, a high amount of kinetic energy occurs in the pallets. With this energy, very strong blows are applied to the material fed to the machine. With this impact, the material hits the crushing plates and breaks. In the first crushing stage, the material is reduced so that it can pass through the distance between the rotor pallets and the grinders. Then, in the second and third crushing stages, it is reduced enough to pass through the distance between the rotor pallets and the jaw mechanism and passes into the discharge chute.

Tertiary Crusher

It is used as a 3rd crusher in the facility.
In addition to obtaining sand thanks to its high rotor speed, it also meets the fine material ratio required by concrete plants in sand. It can also be used as a secondary crusher depending on the hardness and feeding size of the mine. It produces very fine aggregates required for asphalt and concrete production. According to the design of the facility, they can be produced as mobile, fixed steel feet, fixed concrete feet, fixed skid chassis.
From the inlet to the outlet, the distance between the pendulum liners and the rotor blades gets narrower.

Primary Jaw Crusher

It has been developed to crush materials of any hardness and is a highly preferred type of crusher thanks to its low operating costs and easy maintenance. Depending on the location of the facility, they can be produced as mobile, fixed steel feet, fixed concrete feet, and fixed skid chassis.

Although it is generally used in the primary stage, the Secondary models are also preferred in the secondary crushing process.
Jaw crushers apply high pressure to the fed material and break the stones. This mechanical pressure is provided by the elliptical movement of the movable jaw and the narrowing angle between it and the fixed jaw. The fed material is grasped by this elliptical motion and compressed between the fixed jaw and the movable jaw. High flywheel speed, optimal jaw grip angle and specially designed geometry between pitman and rear block ensure maximum control of this mechanical pressure.

Cone Crusher

cone crushers; It is designed to break hard and abrasive stream and quarry materials such as granite, basalt and andesite. It is used as a secondary and tertiary crusher.
Working principle of cone crushers; breaking the materials with the effect of compression, shearing and bending. It offers low dust and wear rates as they compress and break the material.
Thanks to the long-lasting wear parts, the crushing process is longer-lasting. Thanks to its advanced crusher chamber design, it provides high productivity with less wear on the parts. The fact that the crusher chamber is adjustable makes it possible to get the desired size of material.

Vertical Shaft Crushers

They are crushers with high sand ratio and cubicity ratio used to obtain sand and gravel by breaking all kinds of medium-sized hard and abrasive materials. The crushing process takes place by throwing the material fed by the crusher's feeding chamber to the stone lining in the crushing chamber at high speed by means of the rotor rotating at high speed. Spare parts consumption is very economical and it is a low-cost crusher type because the crusher is crushing the stone by hitting the stone.

Vertical Shaft Impact Crushers are preferred at the last stage of the crushing and screening process. It has high production capacity. It can successfully perform the task of breaking watery, moist and sticky materials. Moreover, such materials get rid of some of the water in their body with the kinetic energy that emerges when they collide with the rotor rotating at high speed.

Therefore, the resulting material is relatively drier. Thanks to these advantages, it is more demanded to be used in the production of sand, stone chips and gravel, which are required for concrete and asphalt production. According to the design of the facility, it can be produced as mobile, with fixed steel feet, with fixed skid chassis or as pre-fed.

Closed Rotor

Closed rotor type vertical shaft crushers are preferred for crushing all stone types and highly abrasive materials. The inner surfaces of the rotor are covered with a cast lining. At the outlets, there are diamonds that are highly resistant to wear and can be easily replaced.

It works with the principle of “Rock on Rock”, that is, hitting the stone against the stone. The material fed from the circular chute falls on the distributor liner in the center of the rotor, which rotates at very high speed. A very strong centrifugal force is applied to the material falling into it, thanks to the high-speed rotational movement in the rotor.

In this way, the material with a high amount of kinetic energy is transferred to the crushing chamber at very high speeds such as 60 to 80 m/sec. In this crushing chamber, it collides with the materials pouring from the waterfall windows of the upper body, and the kinetic energy it possesses is transformed into the impact force, and the size reduction process is realized.

Open Rotor

Open rotor type vertical shaft crushers are preferred for crushing light to medium abrasive materials.

There is an open top rotor and an anvil set, which is fixed at a certain angle and distance, covered with steel cast linings, instead of a stonebox around this rotor.

The fed material enters the machine via the feeding tube and falls on the distributor liner in the center of the rotor and is delivered to the crusher pallets. The pallets accelerate the material and throw it towards the anvil. The material is crushed by hitting the anvil and falls into the discharge chute.
