——

Henan Pinyuan Technology Co., Ltd. is located in Pingqiao District, Xinyang City. It's situated at the border of Hubei, Henan, and Anhui provinces and is conveniently located near the G4 Beijing-Zhuhai high-speed, G40 Shanghai-Shaanxi high-speed, 312 National Highway, 107 National Highway, and railway freight stations. Our company offers diversified logistics options which make it easy to choose the best mode of transportation for your needs. Additionally, our factory is located near the non-metallic mining area of Shangtianti and has access to large deposits of non-metallic ore. The main minerals include perlite, bentonite, zeolite, and tuffite. Their perlite reserves rank first in Asia and second in the world with a total proven resource reserve of 867 million tons. This allows them to provide us with stable mineral sources. Our company has opened up more than 30 acres of land and has set up a sand plant and expansion plant. With the upstream and downstream industries being closed, they've enhanced the enterprise's own risk resistance. The main products include Perlite ore, cryogenic insulation Perlite, Perlite filter aid, expanded Perlite, horticultural Perlite, Perlite microsphere, and zeolite particles. Total output can reach up to 50,000 tons annually.

Production Process of Perlite


           Production Process of Perlite

The production process of perlite involves several key steps. The ore extracted from the mine is processed into sand with a certain particle size grading through mechanical crushing and vibrating screening. The expansion plant then selects and purchases the sand according to different purposes. The water content of the raw material mineral sand of perlite is generally 4-6%. To prevent the explosion of perlite, the ineffective water content should be removed before expansion. This ensures that it retains the water required for normal expansion. The production process of expanded perlite includes preheating and expansion, with extensive experiments showing that the best effect after expansion is achieved when the effective water content of expanded perlite is between 2.2 and 2.4%. Overall, these steps ensure that expanded perlite is produced safely and efficiently.

After preheating for 2-8 minutes at a temperature environment of 350-420℃, the moisture content of perlite ore sand will reach the expansion requirement. Following this, the mineral sand is evenly sprayed onto a flame with a temperature maintained at 1100-1200 ℃ through a feeding device. Due to this rapid heating, the mineral sand expands to 10-30 times its original volume and the expanded perlite particles become white or light gray. Inside, they possess a honeycomb-like structure, and a loose density of generally 40-80Kg/m3. Once separated by the cyclone separator with high-temperature gas, the expanded perlite enters the aggregate bin.
