就目前市面上的制砂設(shè)備來說,VSI系列的制砂機(jī)還算是比較新型的,跟傳統(tǒng)制砂設(shè)備相比,它能節(jié)能50%,同功率下,產(chǎn)量提升30%左右。它可以把各種巖石、砂石,河卵石破碎制成附和各種粒度的建筑用砂,其成品砂質(zhì)粒度均勻、耐壓強(qiáng)度高,遠(yuǎn)比天然砂、普通錘式打砂機(jī)生產(chǎn)的砂更符合建筑要求,提高建筑質(zhì)量。

2、工作原理
VSI制砂機(jī)的破碎工作原理,可分為‘石打石’和‘石打鐵’兩種,主要流程細(xì)節(jié)如下:
當(dāng)物料進(jìn)入進(jìn)料斗,經(jīng)中心進(jìn)料孔進(jìn)入,經(jīng)高速轉(zhuǎn)動后拋出;
拋出的物料,先與反彈后自由下落的一部分物料進(jìn)行撞擊破碎,這就是所謂的‘石打石’模式;
撞擊后,拋出物料與下落物料一起沖擊到周圍的渦流腔內(nèi)的渦狀料襯上(或反擊塊上)破碎,這就是所謂的‘石打鐵’模式;
物料與反擊塊撞擊,先反彈至破碎腔頂部,后自由落下,與從葉輪流道發(fā)射出來的物料撞擊形成連續(xù)的物料幕,如此又是一輪‘石打石’、‘石打鐵’模式;
最后,破碎的物料經(jīng)由下部排料口排出;
下面是一組動圖,很好的詮釋了VSI制砂機(jī)的工作原理(模式):
3、應(yīng)用場景
VSI制砂機(jī)主要用于各種石料(如:石灰石、花崗巖、鵝卵石/河卵石、大理石、青石等)的破碎制砂生產(chǎn)線上,下面是一組VSI制砂機(jī)現(xiàn)場的使用場景(sanyyo實(shí)拍):
山友重工VSI制砂機(jī)系列產(chǎn)品的主要優(yōu)勢特點(diǎn)有:
處理量大、產(chǎn)量高——與同等功率下的傳統(tǒng)設(shè)備相比,產(chǎn)量提高30%定。
Large processing capacity, high yield – production capacity is 30 more than traditional equipment at same power
易損件消耗低——單電機(jī)設(shè)計(jì)用電能耗更低,凹形旁通料槽設(shè)計(jì)的“石打石”原理,更合理的破碎腔物料撞擊角度設(shè)計(jì),與耐磨件的摩擦少,延長了耗材的使用壽命,比傳統(tǒng)設(shè)備運(yùn)行費(fèi)用低30%。
Less consumption of wearing parts – less power energy consumption because of the single motor configuration. Stone- to- stone principle is used in designing bypass chute along the concave.
The design of a more reasonable material impact angle within the crushing chamber reduced the abrasion between stone and wearing parts, thence extend the service life of the wearing parts. Its operation cost is 30% lower than traditional equipment.
產(chǎn)品粒形優(yōu)異——產(chǎn)品屬自然碎裂,呈立方體,粒形好、級配合理、細(xì)度模數(shù)可調(diào),特別適合人工制砂和石料整形。實(shí)踐證明比其他傳統(tǒng)設(shè)備制砂、整形效果提高30%以上。
Better shape of end product—material is fragmented naturally. Crushed products is in cube with fine shape. The graduation is reasonable and fineness modulus is adjustable. It is especially suitable for artificial sand and sand shaping. Practice has proved that the shaping effect improved over 30% than traditional sand making equipment.
液壓裝置、易于維護(hù)——配套的液壓開蓋裝置,使破碎腔內(nèi)部件檢修拆換方便、快捷。
Hydraulic device, easier maintenance—Hydraulic system installed for opening cover of the machine makes it easier and quicker for checking, maintaining and changing wear parts inside the crushing chamber.
稀油潤滑、自動保養(yǎng)——配備獨(dú)立稀油潤滑站,雙油泵互補(bǔ)保證供油,無油流、無油壓時(shí)自動停機(jī); 油液冷卻及加熱裝置確保軸承潤滑始終處于最佳狀態(tài)。從而徹底解決軸承發(fā)熱等問題,使主軸軸承保持恒溫,延長維護(hù)周期和使用壽命。
Lubricated with thin oil, maintain automatically—Independent thin oil lubrication station is installed. Design of dual oil pump ensures the complementary oil supply with each other. Machine stops automatically in case of no oil flow or pressure. Cooling and heating equipment for oil guarantees the best condition of the lubrication of the bearing all the time. It thus completely solved the heating problem of the bearing, keeps the spindle bearing at constant temperature, and finally prolongs the maintenance cycle and service life.
國際品質(zhì)保證——新技術(shù)工藝,機(jī)器核心零部件均選用著名品牌。
International quality guarantee—New technology, all core components are with imported famous international brand.
注重環(huán)?!O(shè)備工作噪音小、無污染。
Environmental protection—little noise and no pollution when working.
