Equipment introduction:
The Clay Fired Brick Ultra-fine Crushing Double-Roller Machine from Shandong Qingmai is a high-performance crushing device specifically designed for the brick and ceramic industries. It can further crush raw materials, whether dry or wet, to a particle size of 0.5~1.0mm, meeting the requirements of various products for raw material characteristics. The equipment adopts advanced European technology combined with Chinese manufacturing processes, ensuring its efficiency and reliability.
This is a professional equipment designed for soft raw materials crushing in ceramic, building materials, refractory materials industry and others, it has following features:
1. Two rollers differential operation.
2. Roller gap allowance is up to 2.0mm.
3. The extrusion force can be adjusted within the pressure limit range, subjecting to the material condition.
4. The solid steel structure ensures the safe and stable operation of the equipment to the greatest extent.
5. The roller are fixed on the bearing of a customized center calibration device, ensuring the center adjustment of the equipment.
6. One shaft has two supporting frames, which is flexible to be adjusted and fixed based on gap range, the other is adjusted by two hydraulic pistons and is equipped with an accumulator.
7. By using fixed internal support, the parallelism of the roller gap and the roller can be strictly guaranteed.
8. Equipped with a scrapper and adopts hydraulic control, easy to remove or replace the roller
9. Has sturdy and heavy base support
10. Lathe installed on the frame for periodically treatment of the roller.  

Equipment Specification

Equipment Characteristics：
(1) Ultra-fine Crushing Capability: The minimum roller gap can reach 0.8mm, with a powder fineness that can achieve 0.5mm.
(2) Adjustable Roller Gap: The roller gap can be adjusted at any time within the range of 0.8~2.0mm.
(3) Roller Differential Speed Function: By adjusting the speed difference of the rollers, the powdering effect can be improved.
(4) Various Auxiliary Devices: Equipped with roller grinding devices, energy storage protection devices, pneumatic mud scraping devices, and electrical control safety systems.
(5) High Hardness Roll Rings: The hardness of the roll rings can reach above HRC60.

Equipment Advantages：
(1) High Crushing Efficiency: The equipment can efficiently crush raw materials to the desired particle size, meeting the requirements of subsequent processes.
(2) Strong Adaptability: It has strong adaptability to sticky and wet materials and is not prone to blockages.
(3) Low Energy Consumption:  The equipment operates with low energy consumption, helping to reduce production costs.
(4) Convenient Maintenance: The design allows for the replacement of roll rings without disassembling the bearing housing, facilitating equipment maintenance.
(5) Environmental Performance: Low noise and minimal dust emissions during operation, meeting environmental requirements.

Equipment Structure:
(1) Roller System：The two counter-rotating rollers are the core components of the equipment, responsible for shearing and compressive crushing of the raw materials.
(2) Drive System：Equipped with high-efficiency motors and reducers to provide stable power output to the rollers.
(3) Adjustment Device：Used to adjust the spacing between the rollers to control the crushing size.
(4) Frame：A robust steel frame ensures the stability of the equipment during operation.
(5) Hydraulic Protection System：When hard objects such as metal pass through the rollers in the mud, the hydraulic protection system will elastically retract the rollers under the action of the overload thrust force, protecting the roll skin.
(6) Pneumatic Mud Scraping Device：It continuously lightly adheres to the surface of the roll skin, scraping off the clay on the roll ring surface to ensure a smooth and flat roll skin surface.
