Background technique
Sand mixer is a kind of equipment that sand casting uses, the effect of sand mixer be to enter in mulling machine drum body it is new,
The auxiliary materials such as old sand grain, binder, bentonite and curing agent are stirred, so that sand particle surface be made equably to coat swelling
Native film.It is blended in the time in certain, sand mixer is blended out the molding sand for meeting technique requirement；The Cast sand aeration being blended out simultaneously is not
Agglomeration, to meet the needs of casting and molding.
Increasing to the demand of molding sand with the development of modern style technology, this proposes the equipment for being blended molding sand
Increasingly higher demands.Before the last century 80's, sand mixer mainly uses simpson mill, muller formula mulling
Machine due to its muller roll and kneading action, the molding sand quality being blended is preferable, but the mixed grind time of simpson mill compared with
It is long, cause mulling efficiency lower；Requirement of the simpson mill to power is high, and energy consumption is larger；In addition, simpson mill rolls
Molding sand out influences the quality of molding sand, therefore, simpson mill is gradually washed in a pan by market often with many sand beans or stiff beans
It eliminates.In recent years, rotator mixed sand machine becomes the leading products in sand mixer market.Rotator mixed sand machine is revolved using the high speed of rotor
Turn, so that the bulk sand material of condensation is blended and is uniformly mixed, stiff beans greatly reduce, and it is loose handy to mix the molding sand.But due to
The principle of rotator mixed sand machine mulling is stirring and smashes, and is not rolled and kneading action, therefore, Quality of Mixing Sand is general.It is existing
Sand mixer inside situations such as being easy to appear long-pending sand, scab, there are mulling dead angle, product sand time longer sand lump is hardened, it is more difficult to
It is blended again, once fallen off and be mixed into molding sand, often results in casting wasted product.Therefore it is high to be badly in need of a kind of Quality of Mixing Sand, eliminates mixed
The sand mixer at sand dead angle.
