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
