reliable toothed roll crusher | fote machinery

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.

automatic double roll crusher

Double roll crusher is mainly used for the crushing of medium or lower-hardness mines and rocks with medium or lower rigidity in mine selection, chemicals, cement and building materials industrial production. Roll crusher machine has a theoretical maximum reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher, the absolute smallest size one could expect from the crusher is 1/2 inch. Toothed roller crusher will only crush material down to a minimum particle size of about 10 Mesh (2 mm). Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Roll crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary crushers, reducing the ROM coal. Usually, these crushers will have teeth or raised forms on the face of the roll. (Roll crushers used for minerals and metal ores have smooth faced rolls.)

Tooth Roll Crusher is widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, metallurgy and so on. It can crush materials in middle hardness such as rocks, ore, coke, lump coal, slag, mineral slag, cement clinker, fireproof materials, etc.

Toothed Roll Crusher is worked by making two toothed roll rotate oppositely under the action of two pulleys on two sides of crusher, which driven by one motor or some motors. Thus the materials reaching the required size fall and discharged automatically, while the ones larger than two toothed rollers still left to be crushed until they reach the required size.A roll crusher using compression to crush, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times of the gap dimension. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.

toothed roll crusher for coal preparation plant - ftm machinery

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.

Hotis was a rakshasa initially found pretending to be a dwarf named Hosim, themanager of the Velvet Cabaret in Vasselheim. Half of Vox Machina, as well as Thorbir Falbek and Kashaw Vesh, were contracted to hunt him in "Trial of the Take: Part 3" (1x20).He was slain, with Vax'ildan's killing blow accompanied by a taunt. Hotis eventually revived[8] and later tracked down Vax in Whitestone. As an NPC, Hotis was played by Matthew Mercer.

In Vasselheim, Hotisas "Hosim"had finely-groomed brown hair that fell to his back in two braided ponytails. His beard was very long and capped with a gold ring that caused the end to poof out. He wore heavy makeup; his cheeks were rosy and his eyes were adorned with eyeliner.[9]

Keyleth, Vax'ildan, and Tiberius began their contract for the Slayer's Take along with a driven and mysterious young cleric named Kashaw and a hardened dwarf by the name of Thorbir. The group's mission was to track down and kill Hotis, who was preying on wealthy travelers within the city.

The Slayer's Take trialists chased Hotis down into the catacombs through a tunnel in his room.After losing track of the rakshasa, they fell into the sewers and faced their first obstacle: an otyugh.Although it was a tough opponent, the trialists prevailed, with Keyleth's Blight spell finishing off the creature.Continuing their chase after Hotis, they came upon two undead creatures that possessed Vax and Keyleth, who then turned against the rest of the party until Kashaw drove the spirits out of his allies' bodies. The trialists rested at an acid lake and immediately felt better after eating a Heroes' Feast.When they had crossed partway over the lake on the Carpet of Flying, antimagic glyphs along the walls activated; the carpet and its passengers fell from the air. Several of the party members took significant acid damage and the carpet lost its enchantment before all of the trialists finally reached the other side. As they entered the final room, they heard a soft, silky voiceHotis.

Hotis's disembodied voice, true to the rakshasa's devilish origins, began tempting the trialists away from their mission. On an uncharacteristic natural 20 Insight (Wisdom) check, Thorbir realized they were being tricked and gave the command to attack. With a higher initiative, Hotis started by charming Tiberius, but failed utterly when his magic was countered. Vax flung three daggers at him, the first two missing but the third hitting him in the shoulder for moderate damage.

A shield guardian appeared, and Kashaw cast Sacred Flame at it, but the guardian remained unaffected.The guardian then shot a Fireball that engulfed Kash and Thorbir (who rolled a natural 1) for heavy damage, also dealing splash damage to Tiberius and Keyleth.Vax, however, dodged the spell.Keyleth cast Faerie Fire, which failed against Hotis, so she transformed into her saber-toothed tiger form, Minxie.Tiberius used magic to slow the guardian, but Hotis was once again unaffected.Thorbir attacked the guardian with a series of attacks, damaging it with three successful strikes. Hotis turned to Vax and cast a spell, telepathically controlling the rogue, who then eviscerated Kash before regaining control of himself.

The shield guardian struck back against Thorbir, dealing low damage to him.Meanwhile, Keyleth (as Minxie) mauled the rakshasha for minor damage, and Thorbir slammed the shield guardian several more times.Keyleth repeated her first attack, but Hotis seemed to make the shield guardian take damage instead of himself, and then he began flying.Vax snuck up on the rakshasa and pierced him with a dagger.Although the hit was significant, it was lessened by the shield guardian once again taking damage. Kash manifested a mace out of magical energy and struck Hotis, while Vax was punched by the shield guardian. Keyleth attacked the shield guardian, hitting on two of her attacks and knocking it prone.Tiberius erected an obelisk of stone, crushing the shield guardian, but the agile rakshasa once again dodged out of the way.Hotis taunted them all, promising to hurt their loved ones while beginning to manifest a portal for his escape. Tiberius instantly used Counterspell to prevent the rakshasa's escape. Vax finished off Hotis with a well-aimed dagger.

By impersonating Shaun Gilmore, Hotis gifted Vax with a cursed Robe of Flaying in order to trick him into removing his protective gear and weapons, and invited him to take a walk to an isolated balcony of Castle Whitestone, where Hotis stabbed a surprised Vax.[10]

After a battle in which Vax fell unconscious but was healed by Scanlan, Vox Machina managed to kill Hotis again, with Pike dealing the killing blow with a powerful Flame Strike. Hotis's body violently and painfully exploded into pieces as he swore to return.[11]

Discussing Hotis with Allura Vysoren and Gilmore, the party decided that Hotis's return for vengeance on Vax and Pike is a looming threat that must be proactively addressed. Allura revealed that slaying rakshasas on their home plane will permanently destroy them, so Pike remained in Whitestone to locate Hotis's essence and plan his demise while the rest of Vox Machina pursued more of the Vestiges of the Divergence.[12]

After Vox Machina made their way to the City of Dis, Keyleth scried upon Hotis to try and determine his location. She saw thatin a prison below the cityHotis was in a small, fleshy egg-like form, still in the torturous process of reforming and very vulnerable.

Vox Machina arrived in the room where Hotis was still reforming. He was writhing in a fleshy, egg-like shape, suspended by muscly tendrils. Grog walked forward, raised his hammer, and effortlessly pulverized him, ending his life once and for all.

laboratory-scale validation of a dem model of a toothed double-roll crusher and numerical studies - sciencedirect

A DEM model of a toothed double-roll crusher was established based on bonded particle model.Validation in terms of product size distribution was conducted for three groups of tests.The effects of rotation speed and structure of rolls on the crushing process were investigated.The breakage mechanism of the particle was discussed based on fracture dynamics.

A discrete element method (DEM) model of the crushing process of a toothed double-roll crusher (TDRC) is established using the bonded particle model. DEM results and experimental data are compared quantitatively and a relatively good agreement is observed. The effects of rotation speed and structure of crushing rolls on the performance of TDRC are investigated numerically. The results show that when the rolls' speed is relatively high, the nipping condition would be improved, and more cracks could be created to release the increasing strain energy, generating more fractions of small sizes in the products. But, when rolls' speed exceeds 150rpm, the crushing performance would not be significantly improved. A reasonable working gap and better nipping behaviour are obtained using the spiral-tooth-roll or the staggered-tooth-roll. The validated DEM model could be applied to gain a fundamental understanding of the crushing mechanisms of TDRC.
