Core equipment configuration of quartz sand dry production line
Dry process technology has significant advantages in water scarce areas or
water sensitive processing scenarios. Shanlu Heavy Industry provides a complete
set of dry production line equipment from crushing, screening, magnetic
separation to grading and packaging, suitable for the production of products
with strict requirements for moisture content such as sheet sand, glass sand,
casting sand, etc. The finished products can be directly stored or enter
downstream processes without drying.
Taking the typical dry processing process route as an example: the raw ore is
roughly crushed to below 30mm by a jaw crusher, and then sent to a ZSL vertical
sand making machine for fine crushing and shaping by a belt conveyor. The ZSL
vertical sand making machine designed by Shanlu Heavy Industry adopts the
principle of stone crushing. The material obtains kinetic energy under the
action of high-speed rotating impellers and collides with the lining plate or
material layer for crushing. The particle size of the equipment can be
controlled within the range of 0.5-5mm, and the finished sand particles are
cubic in shape with a needle like proportion of less than 8%. The crushed
material is sent to the YBF square swing screen for precise classification
through a bucket elevator. The screening machine adopts planar rotary motion,
and the number of layers on the screening surface can be configured as 2-4
according to demand. The screening efficiency is stable at over 95%, and
multiple specifications of products such as 20-40 mesh, 40-70 mesh, and 70-140
mesh can be separated at once. The coarse particles on the sieve are returned to
the sand making machine for further crushing, and the fine powder on the sieve
is collected before entering the next process.
Dry iron removal is required for graded sand materials of various
specifications. Shanlu Heavy Industry is equipped with CXT dry permanent magnet
drum magnetic separator in the production line for preliminary iron removal. The
device uses rare earth neodymium iron boron magnetic material, and the magnetic
field strength on the surface of the drum can reach 4000Gs. After the sand is
evenly distributed, it enters the magnetic field area of the drum, and the
magnetic particles are adsorbed on the surface of the drum and discharged with
the rotation of the drum to the non-magnetic area. The non-magnetic sand
naturally falls down and is collected. After CXT magnetic separation, the
removal rate of strong magnetic iron impurities in sand can reach over 90%. For
products with higher requirements, Shandong Heavy Industry can add CXG high
field permanent magnet roller magnetic separators for deep iron removal after
CXT. The magnetic field strength of the roller table of this equipment can reach
over 12000Gs, suitable for the separation of weak magnetic impurities in fine
particles in dry powder, and can further reduce the Fe ₂ O Ⅲ content to below
80ppm. RCYD permanent magnet suspension iron remover can also be configured in
the production line, installed above each belt conveyor, as a protective iron
remover during the conveying process, to remove mixed iron filings, bolts and
other mechanical iron, and protect the safe operation of downstream
equipment.
For scenarios that require micro powder grade products, Shanlu Heavy Industry
can configure MQX dry fine powder ball mill for fine grinding, and obtain narrow
particle size products within the range of D90=10-45 μ m through QF vertical
airflow classifier after discharge. The graded micro powder is further subjected
to deep iron removal by an electromagnetic dry powder magnetic separator, which
has an adjustable magnetic field strength of up to 18000 Gs and is suitable for
powder purification in the range of 10-100 microns.
In terms of dust removal on the production line, Shanlu Heavy Industry is
equipped with pulse bag dust collectors to centrally collect dust at various
dust points, with emission concentrations below 30mg/m ³, meeting environmental
protection requirements. The collected dust can be incorporated into fine powder
products to achieve resource utilization.
Shanlu Heavy Industry is located in Shandong and has over 20 years of
experience in designing and manufacturing mining machinery. Its products cover a
full range of categories including crushing, screening, magnetic separation,
grading, dust removal, and packaging. Shanlu Heavy Industry can provide
customized services from single machine selection to whole line integration
based on customer's raw sand characteristics, finished product particle size,
and purity requirements.
In terms of equipment details, the ZSL sand making machine hammer head is
made of high chromium wear-resistant alloy casting, which extends the service
life by 50% compared to ordinary steel; YBF swing screen mesh tensioning device
achieves rapid screen replacement with short downtime; CXT magnetic separator
drum is coated with a stainless steel wear-resistant layer to prevent wear and
tear; The magnetic roller of CXG magnetic separator adopts rare earth permanent
magnet material, which does not demagnetize; The pulse bag filter bag is made of
laminated polyester needle punched felt, which has low emission concentration
and long filter bag life. These designs reduce the daily operating costs for
customers.
