Types and characteristics of sand making machines produced by 【Yajin Machinery】:

The purpose of the sand making machine is to crush the material to a particle size of -5mm. From the structural classification, it can basically be divided into: horizontal hammer sand making machine, vertical shaft impact sand making machine, roller sand making machine, vertical shaft hammer sand making machine.

In practical application, horizontal hammer sand making machine and vertical shaft impact sand making machine are the most extensive.

Horizontal hammer sand making machine.

The horizontal hammer sand making machine is mainly PX high-efficiency fine crusher (split hammer structure) and sand blasting machine (integral hammer structure). The hammer head and hammer handle of the high-efficiency fine crusher are split structure, and the hammer head is made of high-strength wear-resistant material, and the life of the hammer head is long. The hammer head can be easily replaced.

The bottom has a sieve plate structure, which can achieve effective abrasion and improve the efficiency of sand making.

The hammer head of the sand blaster is a monolithic structure, and the hammer head is directly connected to the rotor through the rod. Due to this structure, the hammer will produce a large force after the crushing process, so the hardness of the material of the hammer is low, so the wear resistance of the hammer is weak. The Courage Sanding Machine has a simple structure, is cheap, and is an option for small job sites.

Vertical shaft impact sand making machine.

According to the structure of the rotor, the vertical shaft impact sand making machine is divided into: open rotor structure and closed rotor structure.

The closed rotor structure is a cage layout of the rotor, and the material falls into the closed rotor from the top and is thrown out at high speed.

The open rotor structure is that the rotor is formed into an open structure, and after the material falls into the rotor, it is beaten out by the throwing hammer.

Roller sand making machine.

In the field of sand making with small production capacity, roller crusher is used as a sand making machine, and there are also some applications. However, the roller sand making machine has poor reliability in the process of long-term use, the failure rate of the equipment is high, and the repair and maintenance are more difficult.

Therefore, for materials with a certain hardness and high abrasiveness, try to avoid the use of roller crushers.

Vertical shaft hammer sand making machine.

The above picture shows the vertical shaft hammer crusher, which can also be used as a sand making machine. This type of equipment does not have a bottom sieve plate, and there is no clogging. The hammer head is a monolithic structure and is connected to the rotor by a threaded rod.

The sand making machine is mainly divided into two types: fixed sand making machine and mobile sand making machine.

Sand making machines have composite sand making machine, (composite crushing), VSI sand making machine (impact crushing), high-efficiency fine crusher, PCL sand making machine and other types.

The sand making machine is commonly known as the stone shaping machine, sand punching machine, stone crusher, etc., the sand making machine has the dual functions of sand making and shaping, which can effectively process river pebbles, pebbles, marble, limestone and other materials into stones and sand with different particle sizes. Sand making machine is a popular production equipment, this article will introduce you to the model of sand making machine.

1. VSI sand making machine

VSI sand making machine has strong comprehensive performance and moderate performance. Compared with the same type of sand making machine, VSI sand making machine products have good particle shape, high output and high efficiency. It is designed to provide high-quality sand and gravel aggregates for concrete batching plants, high-speed railways, highways, high-rise buildings, municipal and other industries, and is the preferred equipment for machine-made sand and stone shaping.

The machine-made sand grade produced has a reasonable complex, excellent particle shape, cubic shape, and adjustable fineness modulus.

2. HVI sand making machine

The shaping effect of the HVI sand making machine is excellent, and the ** is slightly higher. Compared with the traditional sand making machine, it has a deep cavity impeller, which effectively improves the sand and gravel throughput, adopts a combined throwing head, the circumferential guard plate can turn up and down, the crushing chamber adopts a unique material impact angle, and the wearing parts are not easy to wear, which effectively reduces the use cost; It also has the advantages of convenient conversion and flexible adjustment.

3. HX sand making machine

The output of the HX sand making machine is small, and the output is low. HX sand making machine is a sand making equipment developed and manufactured by using the principle and production technology of "stone on-stone" crusher, combined with the actual situation of domestic sand making production. It can be widely used in the crushing of hard and brittle materials such as cement, quartz stone, iron ore, concrete aggregate, refractory materials, etc., especially construction sand and road construction sand.

At present, the types of sand making machines are mainly hammer sand making, impact crushing sand making machines, and box crushing. On the one hand, it uses the impact principle to use materials to collide with each other to crush, which is more durable. On the other hand, the gradation of the processed sand grain type is better.

The sand making machine is a special equipment used for crushing soft or medium-hard and extremely hard ore materials with a hardness of no more than 320 Pa, including pebbles, river pebbles, limestone and other high-hardness ores and other industries, each ore material has different characteristics, so there are different sand making machines.

1. River pebble sand making machine

River pebble sand making machine is suitable for crushing and shaping soft, medium-hard and extremely hard materials. It is widely used in all kinds of river pebbles, pebbles, ores, cement, refractory materials, bauxite clinker, emery, glass raw materials, machine-made construction sand, stone and various metallurgical slags, especially silicon carbide, emery, sintered bauxite, American sand and other hard, super-hard wear-resistant materials, and its efficacy is higher than that of other types of crushers.

2. Basalt sand making machine

Basalt sand making machine is a necessary equipment for making sand from basalt materials. Its appearance is similar to that of the sand making machine, but the sand production rate of basalt is higher than that of the ordinary sand making machine 3 parts. The operation is simple and easy to understand, and it is highly efficient and energy-saving. The basalt material produced is suitable for construction sand and road construction sand.

Vertical sand making machines mainly include impact sand making machines, traditional sand making machines, HVI and VSI sand making machines. According to the working principle of impact sand making, fine grinding of materials is a commonly used production process at present, and the following introduces the rod mill sand making machine and the roller sand making machine.

1. Rod mill type sand making machine

The rod mill sand machine is produced by a motor through a reducer and a peripheral large gear reduction transmission, or a low-speed synchronous motor directly drives the cylinder to rotate through the peripheral large gear reduction transmission. And under the action of centrifugal force and friction, the grinding medium in the barrel crushes the machine-made sand material.

2. Roller sand making machine

The roller sand making machine is mainly composed of rollers, compression, roller support bearings, driving devices and adjusting devices. In the production process of the roller sand making machine, the material is mainly crushed by the adjustment device between the roller and the driving machine.

Sand making machines mainly include: impact crushing, hammer crushing, vertical sand making machines, etc.

Among them, impact breaking is more commonly used, and the effect is also good. Specifically, there are 5X sand making machine, 6X sand making machine and VSI sand making machine.

There are many models of sand making machine, and the sand making machine is mainly divided into vertical shaft sand making machine, hydraulic open-box sand making machine, fine crushing sand making machine, etc.

The model of each sand making machine is different, and you can learn more about which one you need.

The main types are wheel bucket sand making machine, spiral sand making machine, drum sand making machine, vibrating sand making machine, etc., the main models are XL model and XS model, other you can consult the professional manufacturer, call: 67822732, thank you.

What is the model of sand making machine? Or is it a type? You can consult with the technicians of the third brother in Henan.

Construction sand is divided into three categories according to technical requirements:

class, suitable for concrete with strength grade greater than C60;

It is suitable for concrete with strength grade C30-C60 and frost resistance and impermeability or other requirements;

class, suitable for concrete and construction mortar with a strength grade less than C30.

The sand minerals formed under high pressure conditions have tight accumulation of particles, that is, high density and high hardness. Such as diamond (formed at a pressure of 10,000 atmospheres). Since the pressure in the earth's crust increases with depth, the sand minerals formed under high pressure conditions tend to be deep in the earth's crust and in the mantle.

In addition, the directional pressure in regional metamorphism can cause some flake and columnar sand minerals to dissolve in the direction parallel to the pressure and grow in the direction of vertical pressure, resulting in the directional arrangement of these sand minerals in the parent body, such as biotite and quartz in gneiss, and its monomer morphology is different from that in general granite.

1. Sand, also made of sand, is called fine aggregate in construction, which is divided into coarse sand, medium sand and fine sand according to different diameters, and is determined by fineness modulus mf: coarse sand mx=, medium sand mx=, fine sand mx=.

2. Sand is generally divided into two categories: natural sand and artificial sand. Rock particles formed by natural conditions (mainly rock weathering) with a particle size of less than 5mm are called natural sand. Artificial sand is made of crushed rock, which is generally not used due to its high cost and many flakes and powders.

3. The coarseness of sand refers to the average coarseness of sand particles of different particle sizes mixed together. There are usually coarse sand, medium sand, and fine sand. The particle gradation of sand refers to the ratio of sand size particles.

As can be seen in the figure, if it is sand of the same thickness, the void is the largest [Fig. (a)], and the void is reduced when the sand with two particle sizes is matched [Fig. (b)], and the sand with three particle sizes is matched with the void is smaller [Fig. (c)]. It can be seen that the porosity of the sand depends on the degree of collocation of the particle size of the sand at all levels. Graded sand can not only save cement, but also improve the compactness and strength of concrete and mortar.

The thickness of the sand is expressed by the fineness modulus mx. The larger the fineness modulus, the coarser the sand. According to the size range of fineness modulus, the sand is divided into coarse sand, medium sand, fine sand and extra-fine sand.

The sand making machine on the market generally includes: the third generation sand making machine (impact sand making machine) and impact sand making machine, limestone is generally used for sand making with impact sand making machine, the sand making effect is good, the particle size is uniform, and the finished product is 2mm to 50mm, welcome to Hengan Heavy Industry to purchase equipment.
