roll crusher with stable performance | fote machinery
Applied materials: coal, pebble, limestone, dolomite, granite, construction waste, pebbles, glass, cement clinker, basalt, iron ore, quartz stone, coal gangue, etc. Its advantages: high capacity, ability to handle wet, sticky feeds.
Roll crusher, as one of the most economical
and practical crushers, is designed to handle the first and second crushing of
friable minerals and stones such as coal, clay, coal gangue, limestone, slag,
cement clinkers, and shale, etc.
According to the number of rollers, the FTM
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.
Roll crusher is applied more widely than
other crushers because of its small volume and cheap price. With the adjustable
discharging system, it can be used flexibly in coarse and fine crushing processes
of the industries such as cement, chemical engineering, electricity, mining,
metallurgy, building materials, and others.
Roll crushers can adjust the wedge device
between rollers to control the feed and discharge size of the machine. Also, it
is equipped with a spring device to protect the crushing machine and avoid
shutdown caused by overload and iron passing.
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 port becomes
larger, and vice versa.
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, and vice versa.
The unique structure of rollers makes selective
crushing of the roll crushing equipment. Since minerals fed are crushed along its
internal friable crack, the finished products are uniform with the cube shape.
The minerals are crushed under the force of
rollers and machine body, and ores smaller than the gap between roller and
machine frame (of single roll crusher) or roller (of multi-roll crusher) will
pass directly without repeated crushing.
With the supporting CPU, operators can control
roll crushing machines and monitor gaps between rollers, and clean up the
crushing cavity through the central control room, which will help save energy of
30% to 50%.
The main working parts of the roller
crusher is the cylindrical rollers. The rollers are supported by the fixed and
movable bearings, and they are relatively rotating which are driven by the
motor. The materials are crushed by the friction of the rotating rollers, and
the finished products are discharged from the gap of the rollers.
The spring is used to balance the pressure
generated between the rolls. If there are non-crushed materials falling between
the two rollers, the compression spring of bearings can be pushed to make a
large gap so that non-crushed materials can be discharged immediately.
The quality of the crushers has a great impact
on its price. The high-quality equipment will cost more in terms of
workmanship, technology, materials, etc. Meanwhile, it will have a long service
life, low failure rate, and better performance, and bring more profit to

roller crusher | single/double roll crushers - jsxc mine
Roller crusher is a very old crushing equipment that appeared in 1806, and its structure is simple. It can crushers iron ore, Quartz Stone, rock gold, rock tantalum niobium ore, rock tin ore, rock tungsten ore, manganese ore, ilmenite ore, K-albite, limestone, river pebbles, copper ore, bauxite, barite, basalt, etc. Therefore the roll crusher is one of the most widely used crusher machines in the mining industry.
Rock Roll crusher is fine crusher equipment that similar to the hammer crusher. It can crush the compressive strength of less than 160 MPA of materials. Medium feed size, and adjustable discharge size. With the characteristic of low maintenance costs, low requirements for water, reliable performance, less power consumption, less dust, low noise and so on.
Stone roll crusher can be divided into single-roll, double-roll and multi-roll several types according to the number of rollers. According to the shape of the roll surface, have two kinds, smooth roll and tooth roll. The former is suitable for medium and fine crushing of medium hardness ores. While the latter is suitable for coarse and medium crushing of Brittle and soft ores.
The material falls between the two rollers through the feeding opening to squeezing and crushing. Then the finished material falls naturally. In the case of hard or no broken, the role can automatically retreat under the action of hydraulic cylinder or spring. The gap between the roller increase, and the hard or not broken material fall that can protect the machine from damage. The relative rotation of the two rollers have a certain gap, change the gap, you can control the product discharge granularity. Double-roll crusher is the use of a pair of opposite rotation of the Round Roller, four-roll crusher is the use of two pairs of opposite rotation of the Round Roller crushing operations.
3. If the feed material is not uniform along the length of the roller, the roller surface will not only wear quickly but also wear unevenly at every point. The annular groove appears will damage the normal crushing work, the particle size of a crushing product is not uniform. Therefore, in addition to the roller crusher used for coarse crushing, the medium and fine crushing roller crusher is usually equipped with a feeder machine to ensure continuous and uniform feeding. And the length of the feeder is equal to the length of the roller that makes the feed is uniform along the direction of the length of the roller.
4. Reasonable maintenance and proper operation can ensure long-term continuous work, reduce parking time. Only the normal management and daily check the normal working conditions, can prevent failure and ensure continuity of service.
(1) Pay attention to the fastening of the bolts of each component and tighten them immediately if found loose;
(2) Before the work must start the crusher, wait for the speed in normal, then feed materials. The procedure is opposite when stopping;
(3) Check the outlet regularly and remove the blockage if found;
(4) Pay attention to check the wear degree of the wearing parts, at any time pay attention to the replacement of worn parts;
(5) No overload and the electrical instruments keep under constant care;
(6) The bearing oil should be timely, and do not make the bearing oil leakage;
(7) Control the bearing temperature, the temperature rise should not be higher than the surrounding air 25 ~ 30 C;
(8) Dust and other materials should be removed from the underframe plane of the movable device to prevent the movable bearing from moving on the underframe when the roller crusher encounters unbreakable materials, which may cause serious accidents.
The roller crusher composes of a roller wheel, roller supporting bearing, pressing and adjusting device and driving device. The crushing roller is the main working mechanism of the crusher, which is composed of shaft, wheel hub and roll cover. The wearing degree of roll top has a great influence on the working efficiency of roll crusher. Only when the roll top is in good condition, the crusher can get higher production capacity. Because of the importance of roller, it is of great significance to understand the factors affecting roller wear and correct repair of roller.
(1) The material is distributed evenly as far as possible to reduce the wear degree of the ring groove, and roller skin on the surface of the roller;
(2) In the operation of the crusher, especially in the process of coarse crushing. Attent to the size of the ore blocks, to prevent the ore blocks from being too large. It will make severe vibration of the crusher, thus seriously wearing the roll skin;
(3) The selection of roller skin with good wear resistance can reduce the wear degree of roller skin and prolong the service life of Roller;
(4) the length of the feeder shall be the same as the length of the rollers to ensure uniform feeding along the length of the rollers. In addition, in order to continuously feed the ore, the speed of the feeder should be 1-3 times faster than the speed of the stick;
(5) Often check the size of the broken product and move one of the rollers along the axis for a certain period of time, the distance is about 1 / 3 of the size of the ore.
Double Roll crushers are the most common type of roll crushers. The crusher machine uses two opposite rotating rollers to crush the material. It is composed of an electric motor, support, a fixed roller, a movable roller, a safety spring, etc. With smooth and serrated surfaces. The bearings of the active rollers can move along the frame which supported by strong safety springs. The bearing will remove out and spit out the article if the feed material is very hard. The roll surface has smooth and sawtooth.
Two Roll surface is smooth that mainly play the role of extrusion grinding crushing on the material. This equipment often uses for clay, coal, clinker and limestone and other materials in the fine crushing work. The roller surface with the sawtooth of the two rollers. The machine mainly plays the role of cracking and tearing. The equipment is mainly to complete the bulk crushing of materials. The smooth surface of one roll and the sawtooth of the other roll that mainly to play the role of extrusion, bending and grinding on the material. This type of double-roller crusher mainly uses to crushing clay and coal.
