Introduction to Roller Crusher
The double-roller crusher is also called the double-roller sand making machine and double-roller crusher. It is suitable for crushing medium-hard materials in the industrial sectors of cement, chemical industry, electric power, metallurgy, building materials, refractory materials, etc. The double-roller crusher such as limestone, slag , Coke, coal and other materials in the crushing and fine crushing operations. The roller sand making machine has reliable operation, simple maintenance, low operating cost, and adjustable discharge granularity. The roller crusher is a machine that uses the friction force of the roller surface to bite the material into the crushing area, so that it can be crushed by crushing or splitting. When used for coarse crushing or to increase the crushing ratio, teeth or grooves are often made on the roller surface to increase the splitting effect.
Performance Advantages
Can be designed and manufactured according to the hardness of the material
It is used to crush special solid materials. It can be designed and manufactured according to the hardness of the material, that is, according to the material provided by the user, the pressure of the material is measured first, and then the parameters of the roller crusher are designed.
New design to avoid belt slippage
The movable roller and the fixed roller are connected to the power by a hard connection, that is, a coupling. The movable roller adopts universal joint technology, which avoids the defect of belt slippage of the old belt model (large material block).
Intelligent powder selection, increase rate
The feeder adopts a non-powered powder selection structure, that is, before the material enters the roller press, it passes through the non-powered powder selection device, and selects the material below 3-8mm without entering the roller press, only the coarse material is fed through the vibration feed The machine enters the roller press evenly and horizontally, which can improve the crushing efficiency.
Protection mechanism to avoid damage to the machine
In case of over-hard or unbreakable objects, the rollers can automatically retreat by the action of the spring, which increases the gap between the rollers and prevents over-hard or unbreakable objects from falling, thereby protecting the machine from damage.
Adjustable discharge and output
The double-roll crusher can control the discharging particle size by adjusting the gap between the rollers, thereby changing the output per hour.
Working principle of roller crusher
Roller crusher is a machine that uses the friction force of the roller surface to bite the material into the crushing area, so that it can be crushed by crushing or splitting. When it is used for coarse crushing or when the crushing ratio needs to be increased, teeth or grooves are often made on the roller surface to increase the splitting effect.
