Depending on the number of rolls, roll crushers are classified into single-roller type and double-roller type, while according to the smoothness of the rollers, they are classified into single-roller type or hobbing type. Double-toothed roller crushers are commonly used in mineral processing plants. The crushing ratio is 3~15, and the particle size must not exceed 25mm.
DESCRIPTION
Roller Crusher, Double Roller Crusher, Toothed Roll Crusher, Double toothed roll crusher
Double toothed roll crusher is essential equipment in small stone factories and it is a commonly used type of roller crusher. Because of its simple structure, easy maintenance, and low price, it is popular to aggregate and coal ore suppliers.
According to the number of rollers, the roll crushers can be divided into three types: single roll crusher, double-roll crusher, and multi-roll crusher. And the most common one is double-roll crusher.
According to the surface of rolls, it can be divided into smooth roll crusher and toothed roll crusher. (The following roll crusher refers to “smooth roll crusher”.)
Double toothed roll crusher is suitable for crushing various types of ores, used as secondary or tertiary crushing machinery. It is widely used in construction, metallurgy, building materials, water conservancy, electricity, refractory, and other industrial sectors.
Double toothed roller crusher is generally used for crushing medium-hard rocks with compressive strength of less than 200 Mpa, such as limestone, phosphate, basalt, granite, river pebbles, iron ore, gold ore, copper ore, lead-zinc ore, nickel ore, asphalt, bricks, cement, and other materials.
Double toothed roller crusher is a new type of equipment recommended by major coal plants for crushing raw coal, coke, lignite, and activated carbon. It crushes the coal by squeezing the double toothed rollers and easily removes the materials adhering to the rollers.
The roller crusher has dual functions of pre-screening and crushing. Small and medium-sized materials in the coal mine are directly leaked from the gap between the toothed rollers to avoid reprocessing. The phenomenon of over-crushing is improved.
The toothed roller crusher is very useful for crushing clay, cohesive materials, or rocks mixed with soil with water content up to 30%, such as kaolin, bentonite, montmorillonite, etc.
Because equipped with a scraper and adjustable discharge size, it can keep the groove and working surface clean. For wet and viscous materials, it can easily complete the crushing operation without sticking or clogging.
The double roller crusher is equipped with a discharge regulating device. The crushing gear is operated by a hydraulic system, which is used to adjust the space between tooth rollers, more convenient and fast operation.
According to the actual production requirements, the users can adjust the size of the discharge by adjusting the top bolt of the wedge-shaped device. The particle size of the crushed product can reach 2-10 mm, to meet the need of different users.
A double toothed roll crusher with less volume is composed of two toothed rollers, which are installed in parallel and rotated 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.
Toothed roll crusher has good applicability and plays an important role in open-pit mining, especially in open-pit coal production. Four reasons for open-pit ore crushing:
