F Size Introduction

The following is the introduction to F Size. FEPA-F, There are multiple standard versions for grain sizes. The European FEPA (Federation of European Producers of abrasives). Within the FEPA sizes, you can also distinguish between FEPA-P and FEPA-F. F sand is an applied particle size specification for abrasives and refractories materials. The particle size numbers are: F4, F5, F6, F7, F8, F10, F12, F14, F16, F20, F22, F24, F30, f36, F40, F46, f54, F60, F70, F80, f90, F100, F120, F150, F180, F220, F220, F230, F240, f280, F320, F320, f280, F320, F320, f280, F320, F360, F400, F600, F800, F1000, f1200. Among them, f4-f220 is called “grit size,” which is produced by screening, and f230-f1200 is called “micro powder,” which is produced by multi-purpose water separation, airflow and ultrasonic circular vibrating screen Welcome to contact us to exchange what is F Size meaning? and look forward to your information.

What is melting vs. Sintering?

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

What is your terms of payment?

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.

How about your delivery time?

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.

What is your sample policy?

We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost. 

Are you a manufacturer or trader ?

Yeah, We are the manufacturer of BFA, WFA, GC. Also,we had good business relationship with others abrasive media & refractory raw materials manufacturer . more over we have QC department which make strict inspection on goods quality, packing, so we can provide a stable and quick delivery of all the

Amount of abrasive applied:

This decision is made by knowing the type of material you will be working with. Open Coat – Here, the abrasive granules cover from 50% – 70% of the backing and are set at pre-determined spacing to reduce loading. Used on softer surface materials that tends to load or fill

Form and shape of the abrasive:

This decision is made by determining how the abrasive will be used by the individual. Abrasives are sold in forms such as sheets, large/small discs, belts, and large/small rolls. Selecting the right form is determined by whether the abrasive will be used for hand. sanding, applied to a large disc
