High pressure roller crusher

Abstract

The invention relates to a high pressure double-roller crusher, which comprises a feeding device, a discharge device, a rack, a motor, and a regulation device. The motor is connected to one end of a first roller shaft through a power transmission device, the other end of the first roller shaft is connected to one end of a second roller shaft through a transmission device, so that the first roller shaft, the second roller shaft and compression rollers connected to them rotate in opposite directions synchronously. The regulation device is fixed on the rack, and consists of a hydraulic cylinder. The cylinder body of the hydraulic cylinder is fixed on the rack, the piston of the hydraulic cylinder is fixedly connected to a connecting piece, the connecting piece is in bearing connection with the second roller shaft, the oil cylinder on one hydraulic cylinder side far from the second roller shaft is internally provided with a pressure sensor, the oil inlet pipe of the oil cylinder is provided with an oil pump, the oil outlet pipe of the oil cylinder is provided with a valve, and the pressure sensor is in electric connection with the oil pump and the valve. One motor is used, a unilateral torque support arm is employed to bear torsion, and the fixed roller transmits the torque to the movable roller through a group of floating gears. The transmission way can save 25% of power consumption in cost, and reduces 40% of the floor space.

Description

technical field [0001] The invention relates to crushing equipment, in particular to a high-pressure double-roll crusher. Background technique [0002] In 1977, Germany developed the world's first high-pressure roller, and in 1985, it was developed in China. Nowadays, roller presses have been widely used and extended from the cement industry to coal, metallurgy, chemical industry, and mining. Using the roller press as the previous process of the ball mill or directly as the grinding process of brittle materials has achieved a significant increase in the market effect. It can be foreseen that the era of the roller press replacing the ball mill that has been in use for 150 years is not far away. The pulverization by the ball mill is single-particle pulverization, and the powder has the following disadvantages in the process of changing from large to small: 1. The hit rate of the impact is extremely low, and its probability is only 1 / 1000; 2. The impacted particles move random...

Problems solved by technology

The pulverization by the ball mill is single-particle pulverization, and the powder has the following disadvantages in the process of changing from large to small: 1. The hit rate of the impact is extremely low, and its probability is only 1 / 1000; 2. The impacted particles move randomly around , there is no constraint, and the impact force cannot be fully absorbed; 3. There is a stagnation zone in the movement track of the material rotating with the cylinder, in which the grinding body only does useless work on the material and consumes a lot of energy; 4. The noise is large at 100- 130db; 5. The mill is seriously worn out and the loss is large; 6. A layer of fine powder will be adsorbed on the surface of the liner to act as a cushion, absorbing energy consumption and causing over-grinding

However, the current high-pressure crushers all have dual motors, and each motor drives a roller end shaft, which consumes a lot of power
