As we all know, roll crusher is very important in crushing, just like . Roll
crusher can be classified into Double roll crusher, four-roller crusher and
toothed roller crusher.
1. The double roll crusher
This series of double
roll crusher mainly consists of roller, and roll wheel support bearing, pressure
and adjusting device and actuating device.
Adjustment of discharging grain
size: there is wedge or gasket adjusting device between the two rolls.
Adjustment bolts are on the top of the wedge device. When the adjustment bolts
pull the wedge block up, the wedge block make movable roll leave fixed pulley so
that the interval between two rolls is larger and the discharging grain size is
larger. When the wedge block is down, under the role of retainer spring, the
movable roll will come near the fixed pulley so that the interval between two
rolls is smaller and the discharging grain size is smaller. Gasket adjusting
device can adjust the discharging grain size by increasing or decreasing the
number of gaskets or thickness. When the gaskets are added, the interval between
two rolls is larger and when the gaskets are reduced, the interval between two
rolls is smaller and the discharging grain size is smaller.
2. The toothed
roll crusher
Toothed roll crusher features high crushing ability. The
distance limited type hydraulic coupler combines the electromotor and speed
reducer to prevent power overload. Sensor features overload protection, which is
safe and reliable. The intervals between toothed rollers are adjusted by
hydraulic pressure. Toothed roll bearings are lubricated concentratedly. The
tooth shape is optimization design. Pull and shear do chosen crushing. The
toothed roller crusher features high efficiency and low energy consumption and
it can produce the uniform grains. The toothed roller crushers are classified
into two series, double toothed roller crusher and four toothed roller crusher.
Double toothed roller crusher is mechanical spring type (2PCM) and this type
crusher can be equipped with thick teeth roller or medium teeth roller
respectively, according to the material properties and requirements. Four
toothed roller crusher is the combination of two sets of double toothed roller
crushers.
