Dehydration of quartz sand tailings is an important environmental protection
process in the production of quartz sand. The commonly used tailings dewatering
equipment mainly includes belt filter press and plate frame filter press. Both
have their own characteristics in terms of structure, processing capacity,
operating costs, and applicable scenarios. The specific selection comparison is
as follows:
1、 Comparison of processing ability and adaptability
Belt filter press has the characteristic of continuous processing and is
suitable for tailings dewatering operations with large processing capacity, high
moisture content, and moderate material viscosity. Its dehydration process is
stable and highly automated, making it suitable for situations with large
tailings output in quartz sand production lines. Plate and frame filter press is
suitable for processing fine particles or materials with high mud content. It
has good filter press effect and low moisture content in the mud cake, but the
processing cycle is long. It is suitable for working conditions with small
output and high requirements for mud cake degree.
2、 Comparison of Mud Discharge Effect
The plate and frame filter press is superior to the belt filter press in
terms of dewatering effect, and the degree of mud and biscuits is higher after
dewatering, which is convenient for subsequent processing or transportation.
Although the dryness of the belt filter press is slightly lower, its processing
efficiency is high and it can achieve continuous dewatering, making it suitable
for situations where the moisture content of the sludge is not extremely
required.
3、 Comparison of Equipment Maintenance and Operating Costs
The operation and maintenance of belt filter press is relatively simple, and
continuous operation reduces the frequency of manual operation. It also has low
energy consumption and economical operating costs. The plate and frame filter
press, on the other hand, has a complex structure, requires frequent replacement
of filter cloth, periodic cleaning, high manual participation, and high
operating and maintenance costs.
4、 Comparison of Automation and Control Levels
Belt filter presses are generally equipped with automatic control systems,
which are easy to operate and facilitate linkage control with the entire
production line. The automation level of the plate and frame filter press is
relatively low, and some old-fashioned equipment still requires manual
operation. Its automatic control capability depends on the specific
configuration.
5、 Suggested Applicable Scenarios
If the tailings discharge of the quartz sand production line is large and the
treatment frequency is high, it is recommended to use a belt filter press, which
has strong continuity and high efficiency, and can meet the needs of large-scale
tailings treatment. If the tailings treatment requires high dewatering dryness,
or for fine tailings with heavy mud content, it is recommended to use a plate
and frame filter press, which has strong filtering ability and is convenient for
subsequent recovery or dry stacking.
summarize
Belt filter press is suitable for quartz sand production lines with high
output, low mud content, and the need for rapid continuous dewatering, while
plate and frame filter press is suitable for processing tailings containing fine
mud or requiring high dewatering dryness, and is more suitable for processes
with small and medium output and strict mud requirements. When selecting,
comprehensive consideration should be given to factors such as actual tailings
properties, production capacity requirements, and on-site automation level.
