new kind of energy-saving cement grinding equipment mill roller press
Product Introduction
Also called extrusion mill roller press, roller mill, is a new kind
of energy-saving cement grinding equipment, replace the high energy
consumption, low efficiency of ball mill grinding system, and
reduce the steel consumption and noise function, apply to the
new plant construction, also can be used in old factory technical
renovation, make the ball mill system yields by 30-50%, after
extrusion, the material feeding bread in 0.08 mm thin material
accounts for 20-35%, accounted for 65-85% less than 2 mm, the
internal structure of small particles, filled with many tiny crack
because of extrusion, and greatly improve ease of grinding. The
roll surface is hot surfacing, and the maintenance of wear
resistant layer is more convenient.
Working principle
Roller press is designed according to the principle of material bed grinding, its main characteristics are: high pressure, full speed, full material, material bed crushing. The roller press consists of two extruding rollers which rotate synchronously in the opposite direction, one is the fixed roller and the other is the movable roller. The material is fed from the top of the two rollers, which is continuously carried between the rollers by the extrusion roller. Under the high pressure of 100-150mpa, the compacted cake is discharged from the bottom of the machine. The discharged cake contains a certain proportion of fine finished products. In the interior of non-finished particles, a large number of cracks were generated, which improved the material's wearability, and greatly reduced the energy consumption of grinding in the further crushing process. The material through grinding roller is mainly divided into three stages: full material density, lamination and crushing, agglomerating and discharging stage.
Structural Features
Roller press consists of frame, two roller system, transmission
device, torque support, roller cover, feeding device, hydraulic
(pressurization) system, main bearing lubrication system, dry oil
lubrication system, electrical system and other parts.
(1) increasing production: in grinding roller machine installed in
the system, the high voltage load by double roller diameter is
passed to the grinding material layer, the interaction between the
most energy is used in the material extrusion, sound energy and
heat energy produced by the friction material can be converted into
material deformation, the deformation, tearing, crushing, can give
full play to the potential power to make the grinding equipment,
increase production of up to 50-100%, the total energy consumption
can be reduced by 20% - 30%, improved the production efficiency of
the whole system.
(2) reduce power consumption: grind materials with roller press.
Not only the particle size of the material is greatly reduced, but
the bond function index is also significantly reduced, which
greatly improves the grinding condition of the subsequent mill and
significantly reduces the unit power consumption of the whole
grinding system. The total power consumption of the grinding system
can be significantly reduced. Compared with the traditional
grinding method, the energy saving is 25-50%, and the annual
electricity saving benefit is considerable.
(3) saving investment: compared with tube mill, roller mill with
the same production capacity is simple in structure, small in size,
light in weight and small in space, which can save civil
construction investment and facilitate the transformation of the
original grinding system. In addition, the operation and
maintenance of roller press is also very simple.
(4) good working environment: the material is continuously and
stably crushed in the extrusion roller cover, and the harmful dust
is not easy to be diffused. At the same time, because there is
almost no impact, the noise of the roller is much lower than that
of the tube mill.
(5) easy to develop: the traditional tube mill is restricted by
processing, transportation, heat treatment and other conditions,
and the upsizing of tube mill is greatly restricted. The grinding
system of matching roller press solves the problem well. So that
the grinding system to large - scale development into a reality.
