Whats the double roller crusher The Doule Roller Crusher, also known as roll crusher, toothed roll crusher, is suitable for fine crush the medium hardness rock with compressive strength 160MPa, such as ore, rock, coke, coal, clinker, ceramic raw materials, slag, refractory materials, and chemical materials. According to the number of rolls, the roll crushers can be divided into single roll crusher, double roll crusher or, four roll crusher. Double roll crusher is the most used type. We produce industrial roller crushers and laboratory uses small roll crusher. Advantages Replacement wear-resistant lining, long service life, convenient maintenance. Compact structure, lightweight, small size, for the same production capacity requirements of the crushing system, equipped with roller crusher can significantly save investment. The width of the discharge opening can be adjusted to determine the crushed material size. High reduction ratio, low vibration, dust removal, and less noise. High efficiency, low consumption, uniform granule, good granule shape. Roller crusher manufacturer JXSC, a Chinese rock crusher manufacturer, supply roll crushers global, we establish a wear parts supply system to meet customers parts replacement needs are met and reduce the downtime. Factory price, fast delivery, one year warranty, on-site installation, support roll crusher design.
Main partsBearing box, roll shell, bearing housing, adjusting rod, motor, carrier, fixed roller, movable roller and safety spring, etc. Working Principle of Double Roller CrusherThe roller of the roller crusher is supported by the spring pressure. Under normal working conditions, the spring force is sufficient to overcome the crushing force of the crushed material. By changing the number of spacers between the frame and the movable bearing, the width of the discharge port between the two rolls can be adjusted to adjust the grain size. When there is a material that cannot be broken into the crushing chamber, the spring is compressed, and the movable roller is retracted to increase the discharge opening. After the material is discharged, the movable roller is reset under the spring pressure. OperationThe main wearing part of the roller crusher is the crushing roller. Precautions as follows: Iron removal before crushing; prevent sticky mud clogging; pre-pick out the large ore rock; good lubrication condition.
Roller crusher is used for coarse crushing or tertiary crushing. Smooth roll crusher is widely used for industries of ore separating, chemical engineering, cement, refractory material, grinding material and building material, etc. Compared with other crushers, double roller crusher is more excellent in industries of refractory material and mining. In recent years, the roller crusher is widely used for crushing steel grits.
1: Mature making technology, stable performance, little noise pollution 2: Finished products: cubic shape, low acicular content, no crackings inside, fine size 3: Suitable to crush high-hardness materials, little wear and long service life 4: Small cost and fast capital return
Toothed roll crusher is more suitable to crush raw coal and coal gangue in large-sized coal mines or coal separating plants. Teeth roll crusher or double toothed roll crusher enjoys the features of small volume, large crushing ratio, low noise, simple structure, easy maintenance, high working efficiency, even product size and flexible overload protection.
High automation: Hydraulic protector, which is installed in roller crusher, can effectively protect the tooth rollers from being damaged by iron or wood. Besides, there is an automatic clearing device inside, which can automatically remove the adhering materials on wall during the rest period.
Wide application ranges: Being high-efficient, energy-conserving and environmental-friendly, roller crusher is becoming the first choice for thermal power plants. It is suitable to crush brittle materials like soft coal, lignite, coal gangue, sinter, coke, slag, shale and limestone, etc.
Large crushing ratio, energy-conserving and environmental-friendly: smooth roller crusher is more excellent in aspects like large crushing ratio, no demand toward water content in raw material, low noise and vibration, small dust, low energy consumption, small floor space and convenient maintenance.

The crushing capacity of roller crusher machine mainly depends on a pair of cylindrical rollers, which are installed horizontally on frame. Materials are crushed under the active force of rotational rollers. Therefore, we call it roller crusher.
1. Users can take the roller crusher to crush mineral ores with medium harness. Since the shape, size and array of teeth on roller surface can be changed with the property of raw material, either the secondary or tertiary crushing is easy to realize.
3. If the compressive strength of raw material is less than 160MPa, clients can take use of the smooth roll crusher. Double roll crusher has advantages like small discharging size, cheap price, strong wearable parts and reliable operation, etc.
1. If some non-crushing material enter into the space between rollers like drill bit, severe consequence will occur. Therefore, before crushing the material, smooth roller crusher should equip an device for absorbing iron and other matters.
2. If the double roll crusher works for a much longer period of time, the discharging size of finished products will be overly fine. At this time, users should adjust the discharging mouth or overhaul the whole machine.
The so-called double toothed roller crusher has discharger on its roller, which can clean tooth ace and roller surface. The applied material for teeth roller crusher are diverse. Double toothed roller crusher can crush limestone and rocks with compressive strength more than 200MPa. However, the most suitable materials for teeth roll crusher are clammy ones with water content between 25%-30% or hard material with mud inside. Since the teeth roll crusher has advantages like little dust, low noise and small floor space, etc, more and more people would like to throw olive branch to it.
