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 Double Roll Crushers are used for crushing of friable and brittle materials like Coal, Coke, Sinter (hot and cold), Clay, Earth, Slag, Chalk, Soft Limestone etc. Due to cutting action of the teeth, crushing of material takes place mostly due to shear and not by pressing. Therefore fines generation is bare minimum.

Crushing takes place due to two rolls running in to each other and crushing the material caught in the valley of the rolls. One roll is fixed, while other one is adjustable & spring mounted, permitting un-crushable material to pass through.

Toothed rings are mounted on the heavy fabricated hub and the rings are kept, in position by holding bolts. These rings are made of wear-resistant steel, like Manganese Steel, or any other hardened steel depending upon the application.

Peripheral speed of rolls is kept between 3m-5m/sec and therefore up to 800 diameter roll crushers are driven, directly by V-belts. However, roll crushers above 800 mm diameter are provided with gear box/geared motor to keep the peripheral speed between specified limits of 3 m/ sec to 5 m/sec.

Gap Adjustment system is such, that during operation, gap can be adjusted along with the spring force. There are two spindles located one inside the other in such a way, that inner spindle tightens or losens the springs, while outer one changes the position of the roll.

We, at M/s. Rullitech Engineers are one of the leading manufacturers of Crushing like Stone Coal Crusher, Jaw Crusher, Reversible Impactor, Horizontal Shaft Impactor, Screening, Apron Feeder and Bulk Material Handling equipment.

Williams is an industry-leading roll crusher manufacturer and designer for high-quality roll crushers with desirable benefits such as high throughput capacity, minimal maintenance requirements, low cost per ton operation, and more. Learn more about our heavy-duty roll crushers below or contact our sales engineers to talk about your application needs.

A combination of impact, shear, and compression are the forces necessary to perform the crushing and size reduction in a Williams roll crusher. The material enters the roll crusher machine and is impacted by the roll as it rotates. Then, as the material is pulled between a crushing plate or rolls, shear and compression forces act upon the material. The rolls act as flywheels, contributing to smooth operation and efficient use of power. Roll crushing surfaces operate at a fixed distance apart, as opposed to the continually changing distances in a jaw or cone crusher. This creates a more consistent product size.Roll crushers are low in profile and relatively easy to install. They can be fed with a minimum of headroom, or even choke fed. Adjustments are simple andinternal parts are readily accessible.

Typical feed materials for Williams Roll Crushers include: bauxite, cement clinker, chalk, cinders, clay, coal, glass, gypsum, limestone, burnt lime, rock salt, sandstone, shale, sulfur ore, sea shells, and sewer sludge clinker. Single Roll Crushers, sometimes called lump breakers, can also be used for breaking frozen or agglomerated materials.

Williams Roll Crushers are used in a variety of industries such as, mining recycling, and power industries. Interested in learning more about the Williams Roll Crushers for your specific industry and application? Contact our sales engineers!

Choosing between a single roll crusher and double roll crusher depends upon the type of feed material, feed size, product size desired, and consistency of both feed and product. Both single and double roll crushers operate most efficiently with dry, friable materials. However, single roll machines have been widely and successfully used for the reduction of moist clays. They also have been long used as primary and secondary coal crushers, both at mine sites and power plants, where a minimum of fines is desired.

Williams single roll crushers reduce via a combination of impact, shear, and compression. The rolls are always toothed in patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities and are particularly well suited to be used as lump breakers.

Double roll crushers reduce primarily through compression, although some shear is obtained with toothed rolls. Rolls for these crushers come in combinations of smooth, corrugated, and toothed designs. Double Roll Crushers produce a finer product at lower reduction ratios and capacities.

Oversized, heat-treated, alloy steel shafts plus self-aligning, roller-type bearings assure long life and maximum use of power. Jackshafts for control of roller speed are standard on double roll crushers, optional on larger Single Roll Crushers.

Heavy-duty compression springs permit movement of floating roll to pass tramp metal and other uncrushables, avoiding overload and damage. Smaller Single Roll Crushers are equipped with a shear pin release.

Faces Tooth patterns and corrugations to fit feed material; abrasion-resistant alloy; easily replaceable. Ash Crushers have additional features including dust-tight design and sealed cover plates for breaker plate access.

Williams Single Roll Crushers are also available in a 15 inch (381mm) diameter dust-tight version for applications such where it would be expensive to have dust collection air. Already well known for rugged construction, low profile, high reduction ratio, and economical cost, Williams Dust-Tight Ash Single Roll Crushers also have easy access to the rotor for maintenance. These dust-tight roll crushers are perfect for applications such as crushing ash, limestone, coal, or glass.
