On the roller crusher, the crushed material will fall between the two rollers through the feeding port, and the finished material will fall down naturally.

In case of hard or unbreakable materials, the roller of roller crusher can automatically retreat by the action of hydraulic cylinder or spring, so as to increase the gap between rollers, and drop the hard or unbreakable materials, so as to protect the machine from damage. There is a certain gap between the two opposite rotating rollers. Changing the gap can control the maximum discharge particle size of the product.

The double roll crusher uses a pair of opposite rotating round rolls, while the four roll crusher uses two pairs of opposite rotating round rolls for crushing operation.

Concrete mixing station is a kind of building material manufacturing equipment which mixes sand, lime, cinder and other raw materials to make concrete. Since it was put into use, it has been playing an important role in China's building materials industry.
Jiuda machinery introduces its main performance features as follows:
1. Widely used performance: the concrete mixing station is mainly divided into four parts: sand and gravel feeding, powder feeding, water and admixture feeding, transmission mixing and storage. The whole equipment is cast with integral steel structure. High quality H-beam not only has a beautiful appearance, but also enhances the overall structural strength of the concrete mixing station. The equipment is easy to install and has various forms, which can be used in various fields It can meet the needs of different projects

2. Good mixing performance: the double horizontal shaft forced mixing machine is widely used in the concrete mixing station, which can not only make the mixer strong, but also achieve good mixing effect for the concrete with dry hardness, plasticity, fluidity and various proportions, with even mixing and high mixing efficiency.

3. Good environmental protection function: the new concrete mixing station equipment has good environmental protection performance. During the operation of the machine, the powder operation is carried out in the full blocking system, and the powder tank adopts high-efficiency dust collector and other methods, which greatly reduces the pollution of dust to the environment. At the same time, the exhaust and discharge equipment of the pneumatic system of the concrete mixing station are all equipped with noise elimination devices The noise pollution is effectively reduced.
