A brief introduction to roll crusher

Roll crusher is a kind of early crushing equipment that appeared in 1806. After many upgrades and modifications of Fote Heavy Machinery, the manufacturing process of the roller crusher has become more mature.

At present, the FTM roller crusher has reached the international level in all aspects and become one of the most popular products in the industry.

Because of its simple and compact structure, reliable operation and low dust pollution, roll crusher is still used in industries such as coal dressing, metallurgy, cement, glass, ceramics, and small ore beneficiation plants, etc.

Usually, roll crusher can be divided into three models according to the number of rolls: single roll crusher, double roll crusher and multi-roller crusher.

Double roll crusher: The two rolls rotate in opposite directions, and the ore enters between the two rolls. Due to the frictional force, the ore is brought into the crushing space between the two rolls and is crushed by being squeezed.

Single roll crusher: Its working principle is similar to that of double roll crusher. In addition to pressure and crushing force, it also uses shear force to crush, and its crushing chamber is broken longer than two rolls. For some special materials (sponge titanium, coke) is effective in crushing.

Applied areas

Roll crusher is widely applied in cement, chemical engineering, electricity, mining, metallurgy, building materials, and others for coarse and medium crushing.

It has high crushing efficiency and adjustable particle size which can crush materials under the compressive strength of 160 MPa. Pebble, ore, construction waste, glass, cement clinker, granite, basalt, iron ore, quartz, and some metals can be perfectly crushed by roll crusher.

The roll crusher also has a good crushing effect in coal industries. After removing the iron and impurities from the raw coal, it can be crushed by roll crusher directly. And the finished product has a uniform particle size and low over-grinding rate.

Roll crusher is very helpful to simplify the coal dressing process and save the investors’ costs of investment and production.

Advantages of roll crusher

Advantages of roll crusher

1. Low noise pollution and reliable performance

The roll crusher has a strong production capacity and reliable performance. The technology adopted can help reduce noise pollution, so that achieves environmental protection.

2. High crushing efficiency and large capacity

The finished product is cubic with good grain shape. And there is less needle-like product, improving the quality and efficiency of production, and reducing over-grinding rate and cost.

3. Long service life of wearing parts

The surface of roll is very wear-resistant. All the wearing parts are made of materials with advanced techniques and wear resistance, which can crush hard ores.

4. Adjustable discharging size

The discharging size can be changed by adjusting the wedge and gasket between the rolls.

5. Wide range of applications

Roll crusher can be applied for fine crushing of rocks with high or medium hardness in the industries such as beneficiation, chemical engineering, cement, refractory materials, abrasive materials and building materials, etc.

Working principle of roll crusher

Working principle of roll crusher

Working principle of roll crusher

The main working parts of the roller crusher is the cylindrical rollers. The rollers are supported by the fixed bearings and movable bearings, and they are relatively rotating which are driven by the motor. The material is crushed by the friction of the rotating rollers, and the crushed material is discharged from the gap of the rollers.

The spring is used to balance the pressure generated between the rolls. If there is a non-crushed material falling between the two rolls, the compression spring of bearings can be pushed to make a large gap so that non-crushed material can fall down.

After the non-crushed material passes, the spring can help recover the gap between the rolls to the original size and the roll crusher continues to work.

The adjustment of discharging size

A wedge or gasket adjustment device is equipped between the rollers. And there is an adjustable bolt at the top of the wedge device.

When the adjustable bolt pulls the wedge upward, the wedge pushes the movable roller away from the fixed wheel, then the gap between the two rollers becomes larger, and the discharge size becomes larger, too.

When the wedge is downward, the gap between the two rollers becomes smaller under the action of the compression spring, and the discharge size becomes smaller, too.

The gasket device adjusts the size of the discharge by increasing or decreasing the thickness of the gasket. When the gasket is added, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge size becomes smaller.

Analysis of the roll crusher for sale

The price of roll crusher is influenced by the following factors:

1. Quality

The quality of the crusher has an impact on its price. The high-quality equipment will cost more in terms of workmanship, technology, materials, etc. Mean while, it will have a long service life, low failure rate and better performance, and bring more profit for investors.

2. Model

The different models of the equipment has different prices. The larger model has the higher output and the more expensive price; the smaller model has the lower output and the cheaper price.

3. Factory

There are many factories of roller crushers. The differences in the scale of the factory, production processes, and management methods have created differences in the price of equipment.

Generally, factories with larger scales are more mature, and the production process is more advanced and the workmanship will effectively reduce waste.

At the same time, if they adopt independent research and development and direct sales form, the price of the crusher will be cheaper than others.
