BALL CLAY is often a variety of Kaolinite, like china-clay. It differs from china-clay in getting high plasticity and less refractoriness. In chemical composition, ball and china clays don’t differ greatly except that the former contains a larger proportion of silica. It has derived its name from the practice of removing it within the form of ball-like lumps from the clay pits in the UK.
The key utility of ball clay is its plasticity and it is mixed with non-plastic or less plastic clays to create them ecquire the requisite plasticity. The high plasticity of ball clay is attributed to the reality that it’s fine-grained and consists of a tiny level of montmorillonite. Over 85% in the particle sizes present in ball clay are of one micron or less in diameter. It can be light to white in colour and on firing may perhaps range from white buff. Pyrometric cone equivalent to ball clay hardly ever exceeds 33. shredders used stone crusher
Usually the following proportions (weight percent) of ball clay are typically utilized invarious varieties of ceramics composition:
1. Vitreous sanitary-ware ten to 40
2. Hotel china-ware six to 15
three. Floor and wall tiles 12 to 35
four. Spark plug porcelain 10 to 35
5. Semi-vitreous white ware 20 to 45
six. Saggar bodies ten to 25
7. Glass melting-pot bodies 15 to 20
The wide use of ball clay is primarily as a result of its contribution of workability, plasticity and strength to the bodies in drying. Ball clay, however, also imparts high-drying shrinkage which is accompanied by a tendency towards warping, cracking and from time to time even dunting. This undesirable property is balanced by the addition of grog. sand washing machine south africa
Ball clay crusher: jaw crusher
Jaw crusher adopts the electric motor as the power. The eccentric shaft is revolved by an electric motor by means of v-belts. It causes the swing jaw following the preconcerted path to crush the Ball Clay. Thus the Ball Clay will probably be crushed in the crushing chamber that is composed from the stationary jaw plate, swing jaw plate along with the liner plate. The asndalusite is discharged from the lower portion of machine that’s what you wish.
Ball clay crusher: impact crusher
Impact crusher use impact power to crush ball clay. When the impact crusher functions, the motor drives the rotor rotate in the impact crusher with high speed. When the ball clay get into the area which the hammers effect, under the impact function from the hammer at a high speed, the ball clay are thrown to the impact device above the rotor continuously. silica making process
And then the ball clay are rebounded from the impact liner towards the area where the hammers effects for getting recrushed, then discharged from the discharge port. Users can adjust the space in between Impact Rack and Rotor Support, and then get for the expected size.
