Grinding Stone Introduction

Al2O3 alumina is the starting material of aluminium production, both of metallic aluminium and aluminium oxide. It is porous an has a large reactive surface.

Firstly, We make sure the quality before the goods to be packed, if clients get the item with Substandard products, We have warranty for our clients,we will ship out the new replacements.

fused aluminum oxide products do not have a known shelf life. As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely

Yes, Sample cost below 5 kgs can be refunded when bulk order confirmed,But freight cost for more than 1kg don’t be refunded.

If you take a (1) inch space and add wires to it, the number of openings within the 1″ space is defined as mesh. For example, if the 1″ space has ten openings for particles to fall through, then that sieve would be called a 10 mesh sieve. Typical sieve

When processing minerals in a furnace, materials can either be melted or sintered.  When materials are melted during the production process the minerals go from a solid state, to a liquid state, then is re-solidified during the cooling process creating uniformity in the chemistry throughout the entire batch. The sinerting process

Yes. According to NIOSH, Brown Aluminum Oxide could be a viable substitute for consumers looking for safer alternative materials to high crystalline silica content abrasive products.

T/T 30% as deposit, and 70% before delivery. We’ll show you the photos of the products and packages .before you pay the balance.

Generally, it will take 30 to 60 days after receiving your advance payment. The specific delivery time depends .on the items and the quantity of your order.

This decision is made by the type of abrasive you have selected or the type of process you will be performing. Glue – A straight animal hide glue that is used to adhere the abrasive particles to the backing. Referred to as “Glue Bond”. Resin – A synthetic resin that

Commonly referred to as “grit”, this number designation is determined by the amount of abrasive mineral that can pass through a mesh screen with specific size openings. Therefore, a 40 grit abrasive particle will pass through a mesh screen that has 40 openings in one linear inch. Consequently, the higher
