Diatomaceous Earth is a soft powder formed from the fossilized remains of diatoms (a type of hard shelled algae). Its unique in couple of ways-
It has a very high silica content (which is used to build hair, skin and nails)
It is very hard (Hardness of 7 on Mohs scale)
.
The FDA classifies Diatomaceous Earth (food grade) as generally recognized as safe and is commonly used in things like toothpaste, as an anti caking aid, for clarifying beer or wine, or to eliminate pests naturally.
Diatomaceous earths unique structure makes it a great natural way to kill insects and pests (including intestinal), gently cleanse the digestive system, and improve hair, skin, nails, and teeth.
The strong negative charge of diatomaceous earth means that it naturally attaches to and removes from the body things like: chemicals, viruses, bacteria, heavy metals and even radiation.
Its sharp\ strong structure allows it to puncture the exoskeleton of insects on a microscopic level, causing them to dehydrate and die (while humans and animals are left completely unharmed).
Diatomaceous earth (DE) is recognized as safe for human and animal use, and food grade DE is considered safe for human consumption, even during pregnancy and nursing.
Uses for Diatomaceous Earth
At our house, we use DE regularly to help avoid parasites, to get rid of pests like ants or fleas, and to help improve hair, skin and nails. I also personally know people who have used diatomaceous earth .

Arc Plate Net Shell Support
Keywords: Net Shell Support, Stainless Steel Support, Steel Supports Price
Introduction of Arc Plate Net Shell Support
Supporting of soft rock tunnel excavation has been one of the key technical problems which affects the further development of coal industry production and construction of our country . Deep mine ground pressure intensity is high, under the condition of mining influence and impact ground pressure and strata control is especially difficult, thus support system is more and more strengthened, such as the need to reduce the frame from u-shape set, strengthen the link rod, and even to use U36 steel;spray the anchor net supporting to reinforced by steel arch, or and anchor rope combined support, surrounding rock grouting, etc; Although this can achieve certain supporting effect, but support cost is very high. Therefore, China coal group design to create a new type of flat net shell components, the main supporting characteristics of arc plate net shell components summed up as: "while digging, while supported edge, "before soft to hard", enough stiffness, process simple,low price."
Characteristics of Arc Plate Net Shell Support
1,"While digging, while supported edge",timely support
Arc Plate Net Shell Support can use waste rock filling, grey package after wall, concrete precast slab, such as filling, network frame and the tunnel contour quickly close to stick, while digging, timely support, so that on the one hand can make the support resistance of support was able to play in time, to timely reinforce the surrounding rock and to work under the stress state in three; On the other hand, have the effect of slow pressure, pressure, lead to the uniform support along the perimeter stress, is in good working condition.
2,Arc Plate Net Shell Support has enough "rigidity"
3,"Just moderately soft, before soft to hard".
Arc Plate Net Shell Support force has a complex ingredients: expansion and creep of rock mass, reduce the strength of long, crushing of rock mass adhesion coefficient reduced values, etc., all show the macroscopic displacement of rock mass and any rigid support to prevent displacement will be entirely itself in disadvantage. Therefore, the stability of the laneway to end support, work together to complete of the surrounding rock. Reticulated shell scaffold, while under high in-situ stress reaction in surrounding rock, making convergence of surrounding rock in supporting under the control of convergence, by stent supported edge, the edge of broken rock mass convergence pressure unceasingly, forming a stable bearing ring, together with stents to assume the role of in-situ stress.
The scalability of Arc Plate Net Shell Support comes from two aspects:
(1) the contact of the spatial grid steel supports and surrounding rock itself has certain yielding;
(2) the junctions between the reticulated shell scaffold piece and piece of wood plate.
The Rotary Melting Furnace is a very flexible and universal equipment used for recycling many non-ferrous metals. It is the major lead production technology used in India and many other countries for Secondary Lead Production. A lead production system based on this technology has certain distinct characteristics such as:
•Equipment scalable for installing higher capacities
•Recovers all lead in one production cycle
•Plates & powder from scrap battery as well as slag from Mini Blast Furnace can be used as raw material
•Requires addition of certain consumables
•Can be fired with various fuels
•Generates high Pollution both as Flue Gases & Fugitive Emissions
Description of Rotary Furnace
It is a Rotary kiln in the form of a metallic cylinder with conical sides on both ends. Mild steel plate is used for construction of this shell and its thickness varies depending upon the capacity of the equipment. This shell is rotated on its own axis at 1-2 rpm. For this purposes tyres (also called riding rings) are fitted on the shell. These are fabricated from MS squares or flats, machined for a smooth finish. These tyres ride on steel rollers which are again machined finely. These rollers are fitted on a robust MS structural frame and driven by a gear & motor arrangement. The shell is lined inside with insulation and fire bricks of suitable Alumina content.
Conical ends of the furnace are open on both sides. The furnace is charged with Raw material along with additives from the front end. This side is provided with a movable door on which a burner is mounted. The burner can be a conventional one or a fully automatic one depending upon the fuel used. At the other end, an exhaust block lined with refractory bricks is provided. A tapping hole is provided in the center of the shell from where molten metal & slag are discharged. Flue gases generated are sucked from the exhaust block side of the furnace.
A typical 3.0 TpB Rotary Furnace has the following standard sizes & specifications :
•Outside dimensions of the Rotary
•Shell dia : 2075mm
•Shell length : 2500mm
•Total length : 4500mm
•Charging dia : 450mm
•Exhaust side dia : 450mm
•Refractory thickness : 200mm
•Fuel : Furnace Oil
•Burner : Model 4 A Make: Wesman with complete assembly
•FD Fan capacity : 550 cmh at 44mm of WG
•Gear Box in drive : 8”, 1:40 Ratio
•Motor in drive : 15.0 HP x 960 RPM
•Structure used for base : ISMC 250 x 80
Advantages
•Recovers 100% lead in the first operation.
•Slag produced is lead free.
•Equipment can be scaled up for higher production capacities.
Disadvantages
•Many chemicals are required for operation.
•High power consumption.
•Difficult to produce low Antimony lead suitable for soft lead purposes.
•Fugitive Emissions need to be captured in addition to flue gases.
•Need skilled operators and careful maintenance.
