The HÄNDLE roller crusher series. Roller crushers render cloddy raw materials meterable and pre-pare them for effective further processing in downstream equip-ment. Size reduction is achieved by application of pressure and shear forces between two slowly rotating rollers equipped with one-piece toothed disks or individually replaceable knives.
When crushing tough materials, you need a rolls crusher that gets the job done efficiently. Essa® Rolls Crushers – plain or toothed rolls.
Due to the low crushing ration, the thyssenkrupp Double-Roll-Crusher is producing a product size ditribution with less content of fines and therefore it is the most suitable …
The rolls return to the selected piece sizing program for continual operation. Combining a twin tooth rotor design and a single deck pre-screen allow fines to pass through either before the material reaches the chamber or by falling between the crushing rolls without being further crushed.
Hydraulic double-roll crusher is a kind of double-roll crusher. It is named because its main crushing part is composed of two rollers. The roller crusher is simple in structure and can be used for medium and fine crushing of medium-hard and soft ores. The roller crusher has many advantages such as finer crushing particles, larger capacity, simple …

Crushing rolls might, logically, include roll crushers of the sledging type, the name, by popular usage, is restricted to the double-roll machine (with either smooth or corrugated …
DOVE Roll Crusher also referred to as Double Roller Crusher, or Twin Roll Crusher is highly efficient crushing machine, used in certain applications for primary, secondary …
The (double) roller crusher is equipped with two crushing rollers. According to the granularity required by the user, the roller surface is divided into two types: flat roller surface and surfacing roller surface. Fine crushing operations of 1-10mm are required.
A double roll crusher consists of two rolls. Crushing takes place between two cylindrical rolls with each rotating about a concentric horizontal shaft in opposite directions. This is the most common of all roll crushers. Grinding machines are used for reducing crushed particles into their smallest functional sizes.
The Double roller crusher is a piece of equipment specifically designed to crush ceramic materials. Ceramics, a brittle material commonly used for crafts and building materials like porcelain and bricks, are efficiently processed by this crusher. Two motors drive two pairs of rollers that squeeze and grind the materials. In recycling ceramic waste, residual …
The roller crusher is also called double roll crusher. For roller sand making machine, it uses two motors to drive two pairs of roller shafts to squeeze and grind the material. The roller crusher is suitable for crushing brittle block materials in cement, chemical industry, electric power, mine, metallurgy, building materials, refractories ...
Roll crushers are comprised of two steel cylinders (Fig. 5.24 ). The coal is crushed as it passes between the cylinders. This type of crusher is useful when preparing samples with a minimum of fines generation.
Each Double Roll Crusher is selected and engineered for its specific application, thus roll elements and tooth patterns are selected based on the customer's unique applications and designed to produce a cubical product with minimal fines.
The roller crushers are used for moist and sticky materials. Generally the machines have to be rigid enough to crush also hard inclusions. As the reduction ratio is only about 5:1 a 2-stage crushing is required in most applications. Fast running type crushers like hammer and impact crushers are the simplest and cheapest solution, whenever the ...
The paper presents results of extensive investigations exploring the influences of compressive strength, roll peripheral speed, feed particle size distribution, and single large oversized lumps on throughput of a toothed double roll crusher. A pilot-scale crushing plant in a quarry was deployed to test the crusher with limestone, andesite, …
Binder+Co Double roll crusher. An optimum grain size of 10 to 50 mm is crucial for sensor-based sorting of cullet since a higher content of fines (0-10 mm) would have an …
Double Roller Crushers are Roller Crushers that are widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, and 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, and so on.
Selecting the proper Roll Crusher for an application depends on many factors. When selecting the proper Roll Crusher for an application, you must fully consider all the components of the …
Double roll crusher is a relatively old crushing equipment. After numerous upgrades and transformations, the manufacturing process is more mature. The equipment has a simple structure and less over-crushing. The tooth shape, size and arrangement on the roller surface can be changed according to the nature of the material. It can be used for …
Roll crushers come in different configurations depending on the crushed material and the required output size. Some standard roll crushers include single-roll, double-roll, and …
They have a uniform particle size and high compressive strength. These align more with construction requirements. Therefore, it is popular in mining, metallurgy, building materials, and mineral processing. It is also adopted in sand making, ceramics, and other material fine-crushing fields.
Mechanized crushing has existed for 150 years. Despite the fine differences between the equipment, at the end, they all have the same objective: to reduce the size of rocks - and, of course, to supply the market with products as varied as gravel for construction or iron ore for the steel sector. For these distinctive needs, different types of …
Single roller crushers consist of a single cylindrical roller that operates horizontally. The roller revolves at low speed and breaks the incoming material against the surface of the roller. Depending on the type of roller crusher, the roller may have a smooth, corrugated, or toothed surface to facilitate the crushing process.
