4WhatsAppAir bubbles are blown into the sand bed to make it swirl around. Filtered water then flows through the filter bed in the opposite direction. The polluted matter is released and flows away along with the rinse water. The filtration process can then resume. The yield of a sand filter is determined by two sand filter functions, namely surface filtration and depth filtration. Surface filtration
WhatsApp· Introduction: Milling is the cutting operation that removes metal by feeding the work against a rotating, cutter having single or multiple cutting edges. Flat or curved surfaces of many shapes can be machined by milling with good finish and accuracy. A milling machine may also be used for drilling, slotting, making a circular profile and gear cutting by having suitable attachments.

WhatsAppThe sand casting process also called as sand mold casting. It is a common method for metal casting. Almost 70% of metal casting of product follow by sand casting process. The bonding agent (clay) is mixed with the sand. The mixture is moisturized with water for develop strength and plasticity of clay to make mold. The pattern prepare for required shape of product. which pattern made of wood or
WhatsAppThe working principle of noodle machine is that the flour is extruded by the relative rotation of the roll to form the noodles, and then sliced by the cutting knife of the front machine head to form noodles. The shape of noodles depends on the specifications of the cutting knife. All models can be equipped with different specifications of the cutting knife, so a machine can be made into
WhatsAppWe can use sand to filter water; it works like an abrasive. We can use sand to give a grip to our painting or wall art by combining 2 cups of paint with a ¾ cup of sand. People make sandpaper by gluing sand to a paper. While bunging metal, we can mix sand with clay binder for frameworks used in the foundries. Sand can be used for cleaning up oil leak or any spill by dredging sand on that
WhatsAppThis sucks in sand at a constant rate, via Bernoulli''s Principle, like an aspiration setup in a chemistry class. Find a bucket of sand for the hose to rest in. Find some good method to keep the hose submerged in sand, like ducttaping the hose to the side of the bucket so that it''s always pointed downwards. We just tipped the bucket so the sand was in a huge pile on one side, and stuck the
WhatsAppWorking Principle of Sand Making Machine. Materials falls into the fast rotating impellers from the top of machine and crushes with the material distributed around the impeller under the effect of centrifugal force. After the impact with each other, the material is crushed between impeller and cabinet and then discharged from the bottom.
