Introduction
Quartz sand making machine is widely used in many departments such as mining, metallurgy, building materials, highway, railway, water conservancy and chemical industry. It crushes various materials with compressive strength not exceeding 320 MPa. The crushing method of this series of jaw crusher is driven by extrusion. The motor drives the belt and the belt pulley. The eccentric shaft makes the moving jaw move up and down. When the moving jaw rises, the angle between the toggle plate and the moving jaw becomes larger, thereby pushing the moving jaw plate. The Ding'e board is approaching, and at the same time, the material is crushed, rubbed, and crushed multiple times: when the eaves are moved down, the angle between the elbow and the jaw becomes smaller, and the moving eaves plate leaves the Ding'e under the action of the pull rod and spring At this time, the crushed material is discharged from the lower mouth of the crushing chamber. With continuous rotation of the motor, the crushing motor is periodically crushed and discharged to achieve mass production.
The working method of this series of crusher is curved extrusion type. Its working principle is: the motor drives the belt and the pulley, and moves the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes large, so that Push the movable jaw plate towards the fixed jaw plate, at the same time the material is crushed or split to achieve the purpose of crushing; when the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate acts on the tie rod and the spring After leaving the fixed jaw, the crushed material is discharged from the lower opening of the crushing chamber. With the continuous rotation of the motor, the motorized jaw is crushed for periodic movement to crush and discharge materials, achieving mass production.
working principle
The material enters the sand making machine from the feeding hopper, and is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller. Its acceleration can reach hundreds of times the acceleration of gravity. Then, it is ejected from the three uniformly distributed runners of the impeller at a speed of 60-70 meters per second. It is first crushed and crushed with a part of the material collected from the periphery of the distributor, and then impacts the material lining in the vortex branch cavity together. The material bounces back and strikes the top of the vortex cavity obliquely upward, changes its direction of movement, deflects downward, and the material emitted from the impeller flow channel forms a continuous material curtain. Such a piece of material is subject to two to more than one chance of impact, friction and grinding in the vortex crushing cavity. The crushed material is discharged from the lower discharge port. During the whole crushing process, the materials are impacted and crushed by themselves, without direct contact with the metal components, but crushed and impacted with the material lining, which reduces angular pollution and prolongs the mechanical wear time. The ingenious airflow inside the vortex cavity self-circulates, eliminating dust pollution.
