Hydraulic Roll Crusher

What is Hydraulic Roll Crusher?

Double Roll Crushers are extensively utilized in the mining industry due to their numerous benefits, including high throughput, compact design, low power consumption, capability to process wet and sticky materials, and ability to produce cubical products with minimal fines generation. The dimensions of the roll diameters and widths are determined by the feed size, desired product size, and required capacity.
In the material and grinding system, it can generally increase the output by 30%-40% and reduce the total energy consumption by 20%-30%. 

What Is Hydraulic Roll Crusher Used For?

Typically positioned after primary or secondary crushers, Double Roll Crushers are employed for secondary and tertiary size reduction of a wide range of minerals, such as run-of-mine (ROM) coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, and other wet or sticky feeds.

Hydraulic Roll Crusher Structure Feature

A roll crusher is a crusher that uses Double rolls rotating in opposite directions to break materials. It is mainly composed of roller assembly, roller support bearing, pressure regulating device and driving device. Suitable for feed size less than 80mm, finished product size 50μm-20mm fine crushing process. For example, broken pebbles and construction waste are made into artificial sand, fine crushed iron ore, quartz stone in mines, broken raw materials in the ceramic industry, in the coal industry, after removing iron and impurities can be broken directly. It is suitable for crushing rough and brittle bulk materials with large feed particle size and adjustable discharge particle size.

Working Principle of Hydraulic Roll Crusher

Introduction to the Double Roller sand making machine The double roller sand making machine has special advantages in function compared with the traditional crusher. It uses two motors to drive two pairs of rollers to squeeze and grind the materials. Fine crushing operations where the crushing degree of the rollers is less than 80mm and the finished product particle size is required to be 50 mesh-20mm. Double rollers are used as support, and then the core equipment is fixed on them, and the crushing task is completed under the driving of the motor. At the same time, it also uses double rollers. The motor works together, so its working efficiency is very high, so the output and capacity can meet actual needs. Users are very popular in the process of purchasing this equipment.

Advantageous features of Hydraulic Roll Crusher

• It adopts heavy-duty thickened roller skin, advanced materials, reasonable structure, wear resistance and impact resistance, and cooperates with automatic lubrication device to greatly extend the life of parts;
• The equipment is equipped with an automatic control system, has a compact structure, stable operation, high efficiency and energy saving. Compared with other crushing systems with the same performance, it can significantly reduce investment and use costs, which has great advantages;
• Through hydraulic adjustment, the roller skin gap can maintain stable operation between 1-40mm;
• Equipped with overload protection, when unbreakable objects enter between the rollers, the rollers will automatically avoid and return to the set gap.

Hydraulic Roll Crusher FAQ

Q: What materials can a hydraulic roll crusher handle?
A: It is designed for hard and abrasive materials such as limestone, dolomite, granite, basalt, iron ore, quartz, and coal. It can handle feed sizes up to 50mm and reduce them to 1-5mm in one pass.

2. Q: How does a hydraulic roll crusher differ from a normal roll crusher?
A: The main difference is the hydraulic adjustment system. It automatically adjusts the roll gap when uncrushable objects (like metal or rock bolts) enter the machine. This prevents roll damage and reduces downtime. Normal roll crushers require manual adjustment.

3. Q: Can I adjust the output particle size?
A: Yes. You can easily adjust the output size by changing the hydraulic roll gap. The gap can be set from 1mm to 20mm. This gives you full control over your final product specification.

4. Q: How much maintenance does a hydraulic roll crusher need?
A: Very low maintenance. The hydraulic system protects the rolls from damage. The roll surfaces are made of wear-resistant alloy or can be fitted with replacement wear plates. You only need to check hydraulic oil levels weekly and replace wear parts every 6-12 months depending on your production volume.

5. Q: What is the capacity of a hydraulic roll crusher?
A: Capacities range from 5 to 300 tons per hour, depending on the model and material. For example, a small model (Φ400×250) handles 5-10 t/h, while a large model (Φ1000×800) handles up to 300 t/h. Contact us with your material type and required output for a specific recommendation.
