2PF Series Double Roll Classifier Crusher Working Principle
Material entry: The material to be crushed enters the crushing chamber of the crusher through the feeding device.
Screening: The two rolls rotate relative to each other, and the teeth on the rolls are interlaced with each other, so they firstly screen the materials. Materials that meet the required size will pass through the gap between the teeth and enter the discharge chute directly; while the large materials will be left on the rolls for further crushing.
Crushing process: Large materials are subjected to the action of the teeth of the rollers, including rupture, shear, stretching and so on. The high speed rotation of the rollers produces strong extrusion and shear force, so that the large materials are gradually broken into smaller particles.
Discharge material: The material which has been crushed to a suitable size is finally discharged from the discharge opening, completing the whole crushing process.
During the whole working process, 2PF series double-toothed roll classifying crusher realises high efficient crushing and classifying of materials through the special tooth design and the rotating movement of the toothed rolls, which can crush the materials into the required particle size with good over-crushing rate and crushing efficiency.
Advantages of double toothed roll classifier crusher
一. High crushing efficiency
1.Unique crushing principle: Using the strong squeezing force and shear force generated by the two relatively rotating rolls, it can quickly and effectively crush large materials into smaller particles. Even for materials with high hardness, the crushing operation can be completed in a short time.
2.Continuous crushing process: after the material enters the crushing chamber, after screening, the large materials are continuously crushed, and the qualified size materials are discharged in time, the whole process is smooth and efficient, which greatly improves the production efficiency.
二. Precise particle size control
1.Special tooth design: the shape and arrangement of the teeth on the roll are carefully designed to accurately classify and crush the materials. According to different production requirements, the spacing and tooth shape of the roll can be adjusted to control the size of the crushed material and ensure the uniformity of the product size.
2.Stable grading effect: through the screening effect, it can accurately screen out the materials that meet the required particle size, avoid excessive crushing and ensure the stability of product quality.
三. Strong adaptability
1.Adaptable to a wide range of materials: Whether it is hard ore, brittle materials, or viscous materials, double roll crusher can be better adapted to different types of materials with a wide range of applicability.
2.Adapt to different working conditions: it can operate stably in various harsh working environments, such as high temperature, high humidity, high dust and other environments, which can meet the needs of different industries and production sites.
四. Stable and reliable operation
1.Sturdy structural design: high strength materials are used to manufacture the body and rollers, which have good abrasion resistance and impact resistance, and can withstand long-term high-intensity operation without being easily damaged.
2.Advanced transmission system: equipped with high-quality transmission devices to ensure smooth and reliable rotation of the rollers, reduce vibration and noise of the equipment, and improve the operational stability and service life of the equipment.
五. Energy saving and environmental protection
1.Low energy consumption: compared with other types of crushers,the 2PF series double-toothed roller grading crusher consumes less energy in the crushing process.Its efficient crushing principle and reasonable structural design make the equipment make full use of energy and reduce energy consumption during operation.
2.Low noise: the equipment produces less noise during operation, which reduces the noise pollution to the working environment and neighbouring residents.
3.Reduced dust emission: In the crushing process, through the reasonable sealing design and dust removal device, it can effectively reduce the emission of dust, in line with the requirements of environmental protection.

The following are some common problems and solutions of 2PF series double-Toothed roll classifier crusher:
Abnormal operation of equipment
Unusual rattling sound appears in the crusher:
Reason: There may be non-crushing materials entering the crushing chamber, loose or broken internal parts.
Solution: Clean up the crushing chamber, check and tighten the loose parts, replace the broken parts.
Bearing temperature is too high:
Reason: Generally the lubricant is not working properly (such as insufficient lubricant, dirty) or the bearing is damaged.
Solution: add oil or change oil according to the situation, if the bearing is damaged, replace the bearing.
Equipment vibration:
Reason: the crusher and the motor are installed on different axes, the feed block is too big or uneven, the bearing seat or the ground nut is loose, the tooth cap and the tooth seat are loosely connected.
Solution: Correct and adjust the installation position of the crusher and motor; control the feeding block and ensure uniform feeding; tighten the bearing seat or ground nut; tighten the tooth cap and tooth seat.
Crushing effect problems
Reduced output:
Reason: the tooth cap is worn or the gap between the tooth roll and comb plate, base crushing anvil is too large.
Solution: Repair or replace the tooth cap, replace the comb plate, crushing anvil plate and adjust the gap.
Discharge size does not meet the requirements: it may be caused by the wear of the teeth of the rollers, changes in the distance between the rollers or damage to the internal structure of the crushing chamber. It is necessary to check the condition of the rollers, adjust the spacing or repair the damaged internal structure.
Roller wear is too fast:
Reason: The hardness of the material is beyond the processing range of the equipment, the material of the rollers is not suitable, the feeding method is not correct (e.g. centralised feeding).
Solution: Ensure that the hardness of the material is within the range of the equipment, choose the appropriate wear-resistant material of the rollers, improve the feeding method, so that the material is evenly distributed on the rollers.
Leakage of material at the seal: aging, damage or improper installation of seals will lead to leakage. Replace the damaged seals in time and install them correctly to ensure the sealing effect.
Electrical failure: such as motor failure, control system failure. It is necessary to check the running condition of the motor, the electrical circuit and the parameters and components of the control system, find out the fault points and repair or replace them.
