When it comes to perlite, I believe that many of my friends are not familiar with it or even understand what perlite is. But if there are people who like to grow flowers at home, they must know that the flower pots are often sprinkled with some white pebbles, which are mainly used to transform the soil and help plants produce. Let's take a look at the characteristics and uses of perlite and how the perlite processing equipment Raymond mill helps its application in industry.

 

What is perlite?

Perlite is a kind of volcanic acid lava, a vitreous rock formed by rapid cooling, and is a white granular material with a honeycomb structure. Perlite mines include perlite, obsidian and turpentine. The principle of perlite is that perlite ore is crushed to form ore sand with a certain particle size. After preheating and roasting, rapid heating, the water in the ore is vaporized, and it expands inside the softened vitreous ore to form a porous structure with a volume expansion of 10-30 times of non-metallic minerals.
   

The characteristics of perlite

Perlite is brittle, expands when heated, but does not shrink when cold. It has pearl luster and grease luster, has special arc-shaped cracks, and is fire-resistant.

 

Use of perlite

Perlite can be made into perlite products, which have the properties of light weight, low thermal conductivity, strong sound absorption, no corrosion, no burning, acid-base, non-toxic and tasteless, etc. It is a high-efficiency and ultra-light heat preservation, heat insulation, Sound insulation and decorative materials.

1. Construction field
Closed-cell perlite is the key material for making moisturizing mortar, which is widely used for moisturizing the interior and exterior walls of buildings. Due to the characteristics of perlite, it can be used for concrete aggregates; lightweight, thermal insulation, thermal insulation sound-absorbing panels; fireproof roofing and lightweight antifreeze, shockproof, fireproof, radiation-proof and other high-rise building engineering walls filler, mortar and other building materials.

2. Chemical field
For filter aids and fillers. The processed products can be used to make molecular sieves, filters, detergents; used for brewing, making fruit juices, beverages, syrups, sugar, vinegar and other food processing and manufacturing industries to filter fine particles, algae, bacteria, etc.; purify various liquids; chemical industry Detoxification in plastics, spray paint industry, purification of waste oil, petroleum dewaxing, fractionation of alkanes, hydrocarbons; as filler in pigment enamel, glaze, plastic, resin and rubber industry; catalyst in chemical reaction, and oil well grouting mixture.

3. Horticulture
Perlite can modify soil, regulate soil compaction, prevent crop lodging, control fertilizer efficiency and fertility, and act as a diluent and carrier for pesticides and herbicides.

4. In the beverage, beer, and pharmaceutical industries, closed-cell perlite can be used as filter ceramics, filter aids, etc.

5. In the chemical industry and furnace manufacturing industry, the closed-cell perlite can be used for heat preservation of heat pipes, heat insulation products of furnaces and kilns, and moisture preservation products.

6. In the military industry, closed-cell perlite can replace expensive glass beads in flotation.

7. In the fire protection industry, closed-cell perlite can be used to manufacture various fire-fighting appliances.

 

Application of Raymond Mill for Perlite Mineral Processing Equipment

CLIRIK perlite mill has obvious advantages in performance characteristics, scientific and reasonable structure, and is widely used in the field of perlite grinding with advanced milling technology. Raymond mill is a common equipment for perlite processing. The fineness of the finished product can be adjusted between 80-400 mesh. The output is 30%-40% higher than the traditional mill, and the energy consumption is also greatly reduced.
Number of grinding rollers: 3-5

Feed size: 30 mm

Finished product output: 1-25t/h

Product fineness: 0.022-0.18 mm

Scope of application: This mill can be widely used in metallurgy, chemical rubber, paint, plastic, pigment, ink, building materials, medicine, food and other processing fields.

Application materials: High-yield and efficient processing of non-metallic minerals such as bauxite, titanium dioxide, ilmenite, phosphate rock, clay, graphite, calcium carbonate, barite, calcite, gypsum, dolomite, potassium feldspar, etc. The fineness adjustment is convenient and the operation is simple.

Grinding characteristics: The mill effectively increases the unit output of a single equipment and reduces the energy consumption per unit of output. It has the technical advantages of wide application, simple operation, convenient maintenance, stable performance, high efficiency and environmental protection, and high cost performance, and has a broad market prospect.
