How To Order?	Can You Supply Sample For Test ?
1: Plese tell us the detailed technical parameters you needed	Yes, the sample is free.
2: Then we choose the exact type diatomite filter aid .
3: Pls tell us the packing requirements,quantityand other request.	When Will Make A Delivery?
4：Then we answer these questions and give a best offer.	Delivery time - Stock order: 3 days after receipt of the full payment.- Other order: 15 days after of the deposit.

What Are Your Core Advantage?
1. Source factory, own mine, stable supply of core raw materials for 30 years.
2, The new self-developed low temperature washing storage process, lower product density, longer filtration cycle; The whiteness of the filler higher, the particle size of the product is more uniform, and the vortex value is less.
3. The only large enterprise in China that uses natural gas as a heat source for production, we always take environmental protection as our own responsibility and are committed to achieving sustainable development while protecting the environment.

What Is Your Capacity?
The production capacity of our current diatomaceous earth filter aid is 60,000 tons/year, the production capacity diatomaceous earth filler is 2.5 tons/year, the production capacity of natural diatomaceous earth constant temperature drying product is 15,000 tons/year, the total production capacity of 90,000 tons/year.
