Diatomaceous earth is developed through the fossilized remains of diatoms, which are small, aquatic organisms. The skeletons are made up of silica, which is a natural substance. It is said to accumulate the fine sediments of rivers, lakes, streams, and oceans.
How does Diatomaceous Earth work?
Diatomaceous earth can cause insects to dry out and die by absorbing the fats and oils contained from the material. The sharp edges speed up the process and will remain effective for as long as the material is dry.
Process of How Diatomaceous Earth is made
Step 1: The process and mining of diatomite is a process that is requires precision and delicacy. It requires extensive facilities as well as top-quality equipment to help reduce the amount of material. To help reduce costs, the diatomite material is often mined in an open pit as well as surface mines. However, some processes use specific extraction methods used underground for diatomaceous extract.
Step 2: In surface mining, the overburden which is a thick layer of earth that is removed. Once the thick layer is completely removed, the purest form of the diatomite strata will become immediately exposed. The diatomite material will then be cut from the bed with the help of high scrapers and stockpiled. Due to the soft and fragile material of the diatomite, it does not need to be reduced to a blast.
Step 3: Once the material completes the stockpiled process, it is then hauled to the next processing plant, which is for crushing the material, drying, milling as well as calcining. While the pieces may be as wide as a vehicle, once the material goes into the crusher, the ending pieces will finish in the size of a tiny pea pod. Even when the material reaches the small size, the material will still carry enough moisture.
Step 4: Drying the ore requires a large amount of heat will be applied to the metal in flash dryers. The ore will then be gently milled to preserve the overall structure, which is crucial to make the ore 100% pure. This step is vital as once even the smallest amount of foreign materials enter, the performance of the material will substantially downgrade. The impurities will be removed through a few sets of traps and operators. However, the quality will decrease.
Step 5: For more applications, the ore will then be calcined in a large rotary kiln then to agglomerate then diatoms and produce to the desired grade through a high energy process. The ore will be heated in temperatures that reach well over 1,800 degrees Fahrenheit.
Step 6: To complete the process, the material will be packages and set to retail.
