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.

Toothed roll crusher is widely used in coal, metallurgy, mining, chemical industry, building materials, and other industries, and it is more suitable to crush coal in large coal preparation plant and process waste. Toothed roll crusher has a high crushing capacity. The distance between the rollers can be adjusted by hydraulic pressure. The bearing of the toothed roll crusher is centralization lubrication. Whats more, it has the advantages of optimal design, high efficiency, uniform grain, and low cost.

Protective device: The motor is connected with the retarder through hydraulic coupling to avoid dynamic overload. The sensor overload protection is very reliable. If you have mining project or chemical plant, the toothed roller crusher is prepared for you in China Fote.

The toothed roll crusher is suitable for crushing raw coal in coal mines, coal preparation plants and other industries (allowing less than 30% of coal gangue in raw coal). The crusher is also used to break other brittle materials whose hardness is similar to that of raw coal.

It has the characteristics of high efficiency, long life, full sealing, low noise, and uniform granularity. The double-toothed roll crusher is equipped with a scraper to keep the groove and working surface clean. For the toothed roll crusher, the outlet-size depends on the gap between the two rollers, the size of teeth, shape of teeth, and the number.

The double-toothed roll crusher is relatively small in volume. It consists of two tooth rolls that are mounted in parallel and rotate in opposite directions. According to the crushing capacity and the size of the discharging granularity, the two crushing rolls are uniformly filled with brushing teeth.

And the double-toothed roll crusher adopts the operation way of non-circular, non-intermesh and non-uniform, which can enhance the contact face of roller teeth, and avoid material slippage and improve crushing efficiency.

When the toothed roller rotates, the teeth on the surface of the roller can bite the materials and crush them. Each roller crusher of the crushing system is driven by a separate motor. The roller crusher is generally driven by a belt, and it constitutes the deceleration system along with the reducing mechanism.

FTM double-tooth roller crusher for sand making, limestone, rock, clay crushing has a good crushing effect on wet and sticky materials. And adherence or clogging phenomenon never occurs during the work.

The silicon-aluminum raw material is an indispensable calibration material in the dry cement production process. After the mining work, the materials need to be crushed, transported and stored. and then they are sent to the raw material mill for grinding according to an appropriate ratio.

However, the silico-alumina raw materials have strong water storage capacity and high plasticity index, especially for bauxite and marlstone with water content more than 17% and plasticity index generally above 15. Because of the viscosity of materials, it can lead to blockage and arching during the process of crushing, transportation and storage, thus affecting the normal operation of the system.

In order to solve the problem of adherence and clogging of wet-adhesive materials in the crushing stage, FTM toothed roll crusher is used to break the mixture of limestone and marl. In detail, firstly, the wet and dry materials are mixed and crushed, and secondly, the wet-adhesive materials and other limestone materials with lower moisture content are mixed into the crusher. And finally, they are crushed according to an appropriate ratio.

The toothed roller crusher machine has advantages of small volume, large crushing ratio, low noise, simple structure, convenient maintenance, high productivity, uniform particle size of crushed material, low crushing rate, convenient maintenance, sensitive overload protection, safe and reliable.
