Advanced Design Concept of Fote Roll Crushers

Roll crusher and double roll crusher is driven by the belt conveyor of the electric motor, and through a pair of middle reduction gear rolls, the fixed roll will rotate; and relying on a pair of long gears on the other side of the fixed roll, the movable roll is driven to move, and the two rolls will move in a relative motion in order to squeeze the materials.

Since the local governments all over the country start to concentrate on the mining industry and the mining machinery manufacturing industry, there is no doubt that the roll crusher will have a bright future for further development. However, in most areas in China, there are a lot of macadam plants and sand making production lines with simple equipment configuration and lagging production technology. Although the application of the roll crusher has made contribution to these enterprises, the disadvantages of the traditional roll crusher like unstable performance and high energy consumption still are confusing most manufacturers.

Especially for the mining industry, the roll crusher is applied to directly break raw coal through the steps of iron removal and impurity removal without cleaning the waste rocks. The crushed materials are all in good shape and proper size and the over crushing problem is completely avoided. The roll crusher is designed with simplified coal preparation technique which reduces the investment capital and the production cost.

In addition, we all know that the global mineral resources are reducing as time goes by, so all machinery enterprises need to try to improve the handling efficiency of the mining and processing steps combining the premise of realizing the sustainable development of all kinds of metal and non-metal minerals. Under this circumstance, machinery manufacturers have to be strict with the products they are producing.

Камень является неиссякаемыми природными богатствами

Дробление ударом в молотковых дробилках обеспечивает большой эффект измельчения, чем дробление раздавливанием других типах дробилок, например в щековых или конусных. Степень дробления в ней во много раз выше (доходит до 20-30), а удельный расход энергии на дробление ниже, чем в дробилках, работающих на других способах дробления. Они отличаются высокой производительностью, приходящейся на единицу массы, более компактны.

Молотковые дробилки экономичны, стоимость их на единицу производительности в 1,5-2 и в 3,5-5,5 раза ниже, чем валковых и щековых дробилок, а масса соответственно в 4 и в 4,5-5 раз меньше. В молотковых дробилках гораздо ниже установленная мощность электродвигателя. Они пригодны для крупного, среднего и мелкого дробления самых различных материалов, поэтому могут применяться в пищевой промышленности для измельчения хрупких материалов (сахар, соль) и для измельчения растительного сырья. К достоинствам можно отнести и простоту конструкции.

Молотковые и роторные дробилки по способу действия усилий относятся к ударным. Разрушение кусков дробильного материала в них осуществляется преимущественно путём удара движущимися рабочими органами.

В молотковых дробилках такие удары наносятся по материалу молотками, шарнирно подвешенными на вращающемся с большой скоростью роторе. Сила удара обуславливается скоростью и массой молотка.

По чему разделить минеральные частицы столом

Обогащение на столах – это процесс разделения минеральных частиц по плотности в тонком слое воды, текущей по слабонаклонной плоскости, совершающей возвратно-поступательное движение в горизонтальной плоскости в направлении, перпендикулярном направлению движения воды.

Дека концентрационного стола, применяемого на отечественных золотоизвлекательных предприятиях, обычно выполнена в виде трапеции или параллелограмма и имеет регулируемый поперечный наклон. На поверхности деки закрепляются продольные планки. Высота каждой планки уменьшается по длине ее в направлении к разгрузочной стороне стола. Вдоль длинной верхней стороны деки укреплены загрузочная коробка и распределительный желоб для воды. Во время работы вода равномерным потоком течет поперек всей деки. Обогащаемый материал в виде пульпы подается в загрузочную коробку и через щель у днища коробки вытекает на плоскость деки. Минеральные частицы, поступившие на стол, подвергаются воздействию сил, сообщаемых приводом, смывному действию воды, текущей тонким слоем по уклону поперек деки, и силы тяжести. Под действием силы тяжести частицы оседают на поверхности деки и под влиянием сотрясений деки в межрифлевом пространстве происходит расслоение материала.

Исходный продукт в виде водной суспензии подаётся на концентрационный стол, и течёт тонким слоем поперёк наклонной рифленой поверхности деки. С помощью дифференциального привода дек придается возвратно-поступательное перемещение в продольном направлении. Под действием силы тяжести частицы большой плотности оседают на поверхности деки.
