Application of Coal Gangue Sand Making

2022-03-15

Although coal gangue is a solid waste, it has low carbon content, so its hardness is high. After being processed by a sand making machine, the size of the finished product is relatively uniform, and the compression resistance and permeability are also relatively good, and it is widely used.

 

Coal gangue sand making equipment

At present, there are two types of equipment commonly used in coal gangue sand making machines, namely HVI sand making machines and roller sand making machines.

 

HVI coal gangue sand making machine

 

HVI coal gangue sand making machine is a relatively advanced equipment in sand making equipment. It adopts the crushing methods of “stone-on-stone” and “stone-on-iron”. , the sales are very considerable;

In addition, its crushing cavity is larger, the material passing rate is increased by more than 30% compared with other sand making machines of the same specification, and the output can reach more than 500 tons per hour; and its discharge particle size can be flexibly adjusted to meet the Various sand grain size requirements of users.

 

Roller sand making machine

 

The feeding particle size of the roller sand making machine is less than 150mm, the roll gap of the abrasive roller body can be adjusted arbitrarily between 1mm and 20mm, and the discharge particle size can be controlled reliably. 110t/h;

It has simple structure, small footprint, convenient operation and maintenance, less dust and low working noise, and is a relatively environmentally friendly equipment; it is equipped with an anti-iron device. leak, and then the device operates normally.
