Replacement parts for sand mixers are important part of foundry equipments. The mixing machines are exposed to a lot of wear and tear and looking for best maintenance options is quite a practical thing to do. Buying new mixers is not possible always because of the cost factor involved. Moreover, it is not an intelligent approach to waste away the whole equipment when few replacements can make up for the damage. Proper functioning is the only expectation from the mixing machines and thus some vendors make money by simply providing replacement parts for the machines that are instrumental in the making of a huge building.
Some of the major parts of sand mixers are plows, paddles, sideliners, wheels, bowls, sprue cutters, Digger frames and bottoms. All these parts are meant to provide desired smoothness to the building material. The quality of the look of the building depends upon the quality of the material and that is surely achieved by mixing equipments. The co-ordinated working of these parts is essential for the maximum output delivery by these mixers.
1. Plows and paddles as replacement parts for sand mixers: Plows go through a lot of wear and tear. Tungsten is the material used for making these plows. It is easy to maintain and has long life. The design of the plows is conceived on the basis of the shape and size of the mixing machine and can be customized as per the machine specifications. Plows are also ceramic –faced. Ceramic is able to resist erosion and friction.
Paddles are the parts that are mostly carbide-tipped. Carbide imparts long-lasting quality to paddles. Sintered tungsten material is employed to endure durability. Paddles are the portions that are exposed to maximum wear and tear. Hence, stout material like Tungsten is relevant for use.
2. Bowls and bottoms as replacement parts for sand mixers: Abrasion-resistance is the main requirement for bottoms. Material to be mixed is supposed to have edgy ends that may eat up the surface they come in contact with. Hence, hot-rolled steel bottoms do not require frequent replacement and the low maintenance for
this metal is also assured.
Similarly, bowls employ the use of hard nickel and Gray Iron. The latter is meant for small-scale foundries. Ni-Hard has higher fitting ability than the cast iron bowls and is around five times more durable than the iron bowls. Thus, frequent replacement is totally out of question with Nickel. Completely mechanized set-up matches with the Ni-hard material.
3. Wheels, sideliners, cutters and frames are the other replacement parts for sand mixers: These are the other essential parts that belong to the replacement parts for sale. Polyurethane is the ideal material for wheels. Worn down wheel regains the original size and shape if polyurethane is the material employed for making the wheels. Switching to new wheel can easily be delayed by using this material.
Polyurethane is the favorite choice for sideliners too. The sideliners made of this material last longer than the rubber liners. Sprue cutters need to stand a lot of abrasion. Hence, tungsten carbide is the popular material used for making these cutters.
Cleanliness and uniformity is perfectly achieved while making sprue holes with the carbide cutters. Frames are meant to reduce the pressure on the elevator transport belts. Making smooth ways for buckets to collect the scrape from the walls is the main function of frames. Thus, tungsten carbide serves as the best alternative for replacing worn parts.
The makers of sand mixer equipments conduct extensive research to land upon the improved alternatives to the existing materials. Ability to stand abrasion, wear and erosion are the basic qualities that are worked upon to develop sand mixer parts. The other feature of the material is its availability. Since the sand mixing equipments are high in demand, replacement parts for sand mixers should also be available in abundance.
