Applied material: coal, pebble, perlite, limestone, dolomite, etc. Its outstanding features: high crushing capacity, hadraulic pressure used to adjust the distance between the rollers, and the centralization lubrication on the brearing.
The toothed roller crusher is generally used for the medium and fine crushing for brittle and medium-hard ores, and the size of the crushed product is usually not less than 20mm. Because of its simple structure, easy maintenance, and low price, it is popular to aggregate and coal ores suppliers.
A double toothed crusher with less volume is composed of two toothed rollers which is installed in parallel and rotates in opposite directions. The two-toothed rollers adopt non-meshing and non-constant speed operation to strengthen the degree of occlusion, which ideally prevents the material from slipping thus improving the crushing efficiency.
Generally speaking, materials are crushed in three stages in a double toothed roller crusher. The material enters the crushing chamber by the impact force of the deep tooth gear for the first crushing. The large-block material is cut by the teeth to complete the second crushing, and then being squeezed when they enter the toothed rollers to complete for the third crushing. Finally, the crushed material is discharged from the outlet with the rotation of the toothed roller.
1. The company makes further improvement in the aspects of feed particle size, rotor diameter, rotor channel, etc., so that this series of products can adjust the corresponding rotor structure and the corresponding speed according to different materials and feed grain levels to cooperate, and can achieve higher production volume and higher fineness modulus.
In recent years, with the transformation and upgrading of the coal industry, the requirements for coal development efficiency and environmental protection are increasing day by day. In the field of coal chemical industry, the requirements for product particle size are extremely strict, and generally the particle size is between 25 mm and 70 mm.
If the particle size is too large, the crusher chamber will be blocked, and downstream processing cannot be carried out. The toothed roll crusher is currently used in coal crushing because of its large processing capacity, low fine powder producing rate.
The crusher teeth are composed of big and small tooth phase interval, which can effectively improve the meshing capacity gear roller with the ensure of ideal particle size. Strong meshing capacity can improve the equipment processing capacity, reduce the tooth roller wear, prolong the tooth plate service life.
The connection between tooth plate and tooth roller base is made by screw fastening block, which not only guarantees the connection strength, but also has good interchangeability and replaceability.
Carbon bainite wear - resistant cast steel is used as the material of the tooth plate. The wear resistance of this material is about 40% higher than that of 40Cr surface-welded wear resistant layer. In addition, the whole tooth roller structure, including tooth plate, tooth roller seat, thread fastening block makes strength and hardness of each component more balanced and reasonable.
Besides, the motor is equipped with an electric heating system, and the hydraulic coupler and reducer are made of low temperature synthetic oil which ensures the transmission system smooth operation in the low temperature even with minus 30 .
The Indian customers coal mine adopts the single-bucket truck with semi-continuous mining process, and the raw coal has large grain size, gangue with great hardness. In the original production line, he firstly crushed the material to less than 300mm, then crushed them to less than 70mm by a ring hammer crusher. The crushed material with 70mm was transported to the coal storage bunker by conveyor belt for screening to final products of 25 ~ 70mm.
Technical improvement is urgently needed in order to reduce the operation cost and labor intensity of workers, and ensure the normal operation of the production system. So, the user finally chose Fote toothed roll crusher to replace the original ring hammer crusher.
After the double toothed roller crusher is put into use, the equipment runs stably, and the output particle size of the product has been improved obviously. The comparison shows that there is a 18.2% difference between the qualified products before and after the equipment replacement, which greatly increases the output of the qualified products and creates great economic benefits for the enterprise.

Based on the high quality and complete after-sales service, our products have been exported to more than 120 countries and regions. Fote Machinery has been the choice of more than 200,000 customers.
The main structure of the wheel gearing is composed of fixed roll, movable roll, drive shaft, machine box, chassis, cover piece, and long gear cover. The motive power of the machine comes from the V-belt pulley of the electromotor, and a pair of middle reduction gear will make the fixed roll rotate, and then a pair of long gear drive on the other side of the fixed roll will drive the movable roll, and the two rolls perform relative movement to squeeze the materials.
Advantages: This product becomes the first choice of the heat-engine plant to replace import crushing equipment due to its advantages of high efficiency, energy conservancy, and environment protection.
