Application of industrial filter cloth in horizontal vacuum belt filter machine for chemical refining of potash-soda feldspar powder
In the chemical industry, solid-liquid separation is a crucial step for raw material refining and product purification. Especially in the refining process of potash-soda feldspar powder ( Potash-Soda Feldspar Powder ), how to efficiently separate solid particles from process liquids directly determines product purity, production efficiency, and energy consumption. As a key core component of solid-liquid separation, industrial filter cloth in the horizontal vacuum belt filter ( Horizontal Vacuum Belt Filter , abbreviated as HVBF ) plays an irreplaceable role. Xiamen CITIUS, with over 30 years of experience in industrial filter cloth research and manufacturing, provides reliable solutions for the chemical industry.
1. Process characteristics and filtration challenges of potash-soda feldspar powder refining
Potash-soda feldspar is an important chemical raw material widely used in the production of glass, ceramics, fertilizers, and other fine chemical products. Its refining process generally involves the following steps:
- Ore crushing and grinding : Feldspar ore is crushed to a certain particle size and made into slurry;
- Chemical treatment and leaching : Impurities are dissolved and separated using acid or alkaline solutions;
- Slurry filtration and solid-liquid separation : Separation of filtrate containing valuable components and feldspar solid;
- Washing and drying : Further purification to remove impurities and residual liquids.
During this process, the slurry often has high concentration and high viscosity, with uneven particle size distribution. Some fine particles easily penetrate the filter layer causing turbid filtrate; while coarser particles tend to form a filter cake on the filter cloth surface, increasing filtration resistance. This poses the following challenges for the filter cloth:
- High filtration precision required : Effectively intercept fine particles to keep filtrate clear;
- Balance permeability and strength : Ensure liquid passes quickly through the filter cloth while resisting high slurry pressure and long-term mechanical abrasion;
- Strong chemical resistance : Maintain stable performance in acidic, alkaline, and complex chemical environments;
- Easy cleaning and regeneration : Ensure long-term cyclic use of the filter cloth and reduce operating costs.
2. Advantages of horizontal vacuum belt filter machine
Compared with traditional plate and frame filter presses or rotary vacuum filters, the horizontal vacuum belt filter machine shows obvious advantages in the chemical industry for potash-soda feldspar powder refining:
- Continuous operation
HVBF enables continuous feeding, filtering, washing, and discharging of materials, greatly improving processing capacity and suitable for large-scale mineral powder refining production. - Excellent washing effect
Materials are evenly distributed on the filter belt and can be washed multiple times by spraying, significantly reducing impurity residues in the filter cake and improving product purity. - Controllable filter cake thickness
By adjusting the fabric and vacuum zone parameters, the filter cake thickness can be precisely controlled to ensure liquid permeability and optimize solid recovery. - Strong adaptability
Suitable for high concentration and high viscosity slurry, especially for potash-soda feldspar powder with complex particle distribution in solid-liquid mixtures.
However, HVBF its efficient operation depends on the performance and quality of the filter cloth. The filter cloth is both a " filter ” and a " conveyor belt ” , whose stability and durability directly affect the equipment's working efficiency.
