The sand-making machine is a new type of sand-making and crushing equipment that absorbs many years of research and development experience and technical concepts, adopts a new four-port impeller design structure and a special sealing structure to prevent oil leakage from the bearing cylinder, and has a number of national patent technologies.
VSI sand-making machine has the advantages of high processing capacity, excellent finished sand shape, high wear resistance, easy maintenance, safety and reliability, and wide application fields. It is ideal sand-making equipment in construction, sand and gravel, cement, metallurgy, and other industries.
VSI sand-making machines can produce 1-2 times more sand than traditional sand-making machines under the same power, and the output is stable, which greatly improves production efficiency.
The sand and gravel processed by the VSI sand-making machine are mostly cubic, with good particle shape, reasonable gradation, and adjustable fineness modulus, which can fully meet the current production needs of construction sand.
The design of the VSI sand-making machine pays more attention to the wear resistance and pressure resistance of the equipment. All important parts are made of good castings and profiles, making the equipment more durable.
The equipment adopts thin oil lubrication, automatic maintenance, and a hydraulic cover opening device design, which facilitates later maintenance and observation of the operation of the equipment and reduces maintenance costs.
VSI sand-making machine plays a core role in the sand and gravel production line. It can process and shape various materials to produce sand and gravel aggregates that meet specifications. In the stone production line, the VSI sand-making machine also plays an important role. It can crush and shape stones of various hardness to produce stone products that meet the requirements.
With its efficient, stable, and reliable performance, VSI sand-making machines are widely used in many fields such as construction, sand and gravel, cement, ore, and road construction.
The sand-making machine is composed of seven parts: a feeding hopper, a distributor, a vortex crushing chamber, an impeller body, a main shaft assembly, a base, a transmission device, and a motor.
The material falls vertically into the high-speed rotating impeller from the upper part of the machine. Under the action of high-speed centrifugal force, it will collide with another part of the material shunted around the impeller in the form of an umbrella. The material forms a vortex between the casings, collides and rubs each other many times, is crushed, and is directly discharged from the lower part to form a closed circuit for multiple cycles. After being controlled by the screening equipment, the finished product reaches the required particle size.
