What is a jaw crusher?
A jaw crusher consists of two fixed and movable jaws, with the stones placed between these two jaws. The movable jaw, by moving back and forth towards the fixed jaw, puts the stone under intense pressure, and the crushing process is carried out based on the application of mechanical pressure. By reducing the distance between the two jaws, the stones are broken into smaller pieces and exit the outlet of the machine. The jaw crusher is suitable for crushing very hard and resistant stones.Technical specifications:

- Crushing very hard rocks
- Preparing feed for secondary crushers
- Use in sand and gravel production lines
- Crushing iron, copper, lead and zinc ores
- Use in road construction and civil engineering industries
- Use in mineral processing plants
What is a Hydrocone Crusher?
A Hydrocone crusher is one of the most widely used cone crushers used in secondary and tertiary crushing stages. This device crushes rocks in a controlled manner with a conical system and uniform pressure between the mantle and the concave. The presence of a hydraulic system in the Hydrocone allows precise adjustment of the outlet opening, increases the safety of the device, and prevents damage from the entry of hard or uncrushed materials.
Technical specifications:
Machine size: 36, 45, 55, 66 inches
Production capacity: 50 to 500 tons per hour
Maximum input size: 60 to 300 mm
Output size: 6 to 40 mm
Electromotor power: 75 to 250 kW
Main shaft speed: 300 to 600 rpm
Mantle and concave material: Wear-resistant manganese steel
Opening adjustment system: Hydraulic
Machine weight: 10 to 40 tons
Lubrication type: Automatic
Applications:
- Secondary crushing of mineral rocks
- Tertiary crushing for precise granulation
- Standard sand and gravel production
- Used in hard and semi-hard rock quarries
- Used in mineral processing lines
- Suitable for asphalt and concrete plants
- Used in road construction and civil engineering projects
What is a Cobit crusher?
Cobit crushers are mostly used in the secondary crushing stage. This device works on the basis of an impact system, and after entering the crushing chamber, the stones are hit by the hammers mounted on the rotor at high speed and crushed by the anvil plates. The structure of the Cobit includes the rotor, hammers, anvils, body and outlet adjustment system, which ensures fast crushing and the final product has a suitable and uniform shape.
Technical specifications:
Production capacity: 50 to 300 tons per hour
Maximum input size: 100 to 300 mm
Output size: 0 to 40 mm
Electromotor power: 75 to 200 kW
Rotor speed: 500 to 1000 rpm
Number of hammers: 4 to 6
Hammer material: Manganese steel or wear-resistant alloy
Machine weight: 5 to 25 tons
Output opening adjustment type: Mechanical or hydraulic
Applications:
- Secondary crushing of minerals
- Crushing soft and semi-hard rocks
- Production of asphalt materials
- Use in sand and gravel production lines
- Production of cubic materials
- Application in road construction projects
- Use in concrete and asphalt plants

FAQ about the difference between a jaw crusher, a hydrocone and a qubit
1. How adjustable is the output size of the Hydrocone and Cobit crusher?
The outlet size of the hydrocone is usually between 6 and 40 mm and the cubit is between 0 and 40 mm and can be adjusted with a hydraulic or mechanical system.
2. For the production of building materials and asphalt, is a Kubit crusher better or a hydrocone or jaw crusher?
For the production of asphalt and concrete materials, the Kubit crusher is the best option, for standard sand and gravel, the Hydrocone crusher is suitable, and the jaw crusher is more suitable for the primary crushing of rocks.
3. What is the maintenance and depreciation cost of jaw crushers, hydrocones, and kubits?
The jaw crusher has the lowest depreciation and maintenance cost, the hydrocone has the average and the cubit has the highest cost and depreciation due to the use of hammers and impact system.
4. Does Novin Sand Maker provide spare parts and after-sales service for jaw crushers, hydrocones, and cobits?
Yes, in addition to selling machines, Novin Masesaz supplies spare parts and after-sales service for all stone crushers and provides purchasing advice.
