1. Brief Introduction
Double-roll crusher is for primary crusher for material. It is mainly suitable for crushing
of coke, coal, limestone, chalk, and urea and etc.
2. Mode of operation
Traditional double roll crusher is changed speed by two motors via a belt pulley, each
driving a set of rollers to work, power consumption, and the volume is bulky, vulnerability
of consumption amount is large when the roller wear the adjustment gap it shall regulate
the activities of roller and the drive motor and movable roller at the same time, the operation
is cumbersome.The equipment adopts a single motor through a speed reducing gearbox and
chain plate gear box transmission and drive two groups of rollers at the same time, so that two
groups of rollers always maintain the same speed difference in the working state, It had good
crushing effect, low electricity consumption between the fixed and movable roller system using
our patented product chain plate gear transmission mechanism, when adjusting the roller gap
could only need to adjust spring / hydraulic buffering device.
3. Structure characteristics
We can select different configuration and additional equipment according to the using
three.1 Smooth / groove surface roller
The working surface of crushing roller can choose a smooth or grooved one, smooth
roller is suitable for crushing medium-hard materials, the groove surface roller for brittle
or sticky, wet and materials
need to obtain large crushing ratio.
3.2 Mechanical / hydraulic buffer device
Movable crushing roller equipped with mechanical or hydraulic buffer device, when a
foreign body into the body the protective effect on the work roll will work, it also can
also be used to adjust the gap of the work roll, to compensate the wear consumption
of the roll skin.
three.3 Device for cutting / grinding device
When the roller skin abrasion or appear groove, pit, can directly use cutting device for
roller refurbishment without detaching roller. When change the material and heat treatment
process to improve the lifetime of roller skin. To improve hardness, cutting, using the patent
product of our company in the roller grinding device, grinding roller by quartz at the normal
speed of grinding wheel greatly reduced the labor intensity for repair. Wheel rotation and
take the knife can use electric.
three.4 The gear box transmission chain plate
The main motor through the column axis to drive the reducer, speed reducer through a
fixing roller ball coupling transmission to fix the roller series, between the fixed roller system
and movable roller chain plate system adopts gear transmission, always ensure the best
characteristic of gear meshing transmission regulation or buffer in the activities of the roll
system, strong anti impact force, roll gap adjustment is convenient, do not need to adjust
the position of motor.
three.5 Automatic lubrication system
Automatic lubrication system inject amount of grease to reduce friction and wear, and
has the sealing function for bearing according to the progressive principle.
3.6 Iron remover
The iron remover should be equipped on the feeding belt in order to ensure the continuous,
