Superior quality and easy and simple to handle BH stone sand crusher​

Description:

In response to the increasing demand for large-scale, intensive, energy-saving, environmentally-friendly and high-quality mechanical sands in the sand and gravel market, the “BH” brand has further optimized the structure and function of impact crushing on the basis of thousands of impact crushing and sand-forming application technologies. A new generation of impact crusher vertical shaft impact crusher (also known as sand making machine) has been formed.
This high-efficiency and low-cost new sand making machine is generally used as a three-stage crushing in the stone production line. It mainly produces mechanical sand, which can crush any stone of not more than 20mm to less than 5mm. The grading effect is good and can be widely used in large The smelting, building materials, roads, railways, water conservancy and chemical industries and many other departments, the finished product is a cubic polyhedron, the particles are full, is the core equipment of the mechanical sand professional.

Working principle:

The material falls into the feed port and enters the high-speed rotating rotor through the feed hole. After the launch port is fully accelerated and thrown out, it first collides with a part of the material that rebounds freely, and then strikes the vortex material lining (or counter-block) in the surrounding vortex chamber. ). Then, it is bounced to the top of the crushing chamber, then turned to the downward movement, and impacted with the material coming out of the impeller runner to form a continuous material curtain, and finally discharged through the lower discharge port.

Operating procedures:

1. Check whether the vortex chamber is closed before driving to prevent the material from rushing out of the vortex chamber and causing danger.
2. Check the direction of rotation of the impeller, as seen from the direction of the inlet. The impeller should be turned counterclockwise, otherwise the motor wiring should be adjusted.
3. The starting sequence of the crusher and conveying equipment is: discharging→crushing machine→feeding
4. The crusher must be started at no load, and the material should be fed after the crusher is running normally. The order of shutdown is the reverse of the boot sequence.
5. When the discharge device is stopped, the feeding should be stopped in time. Otherwise, the impeller will be crushed and the motor will be burnt.
6. The feeding force is continuous and uniform.
7. During the operation of the crusher, there must be no severe vibration or abnormal noise. Otherwise, it should be stopped for inspection.
8. Lubrication of the machine, lubrication is dry oil lubrication method, using Mobil vehicle grease special grade, the amount of addition is 1/2-2/3 of the bearing cavity, when the crusher works, add appropriate amount of grease, work After several shifts, open the main bearing to clean the main bearing and replace the bearing if necessary.

Application:

1. Artificial sand making of river pebble, rock (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, and stone chips.
2. Production of building aggregates, highway road fabrics, cushion materials, asphalt concrete and cement concrete aggregates.
3. Mechanism sand production and stone shaping for water conservancy and hydropower, high-grade highways, highways, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal works, high-rise buildings in the engineering field.
