Supply Yan'an stone sand making machine, stone sand making machine manufacturer wholesale price

Yan'an, a prefecture-level city in Shaanxi Province. According to historical records, in Xia, present-day Yan'an City belonged to Yongzhou. Shang belongs to the ghost side. In the Western Zhou Dynasty, it was the territory of Quanrong and Xingxu. During the Spring and Autumn Period, this area was inhabited by the Bai Zhai tribe. In the early Warring States period, the central and northern parts belonged to Wei, the southern part belonged to Qin, and then all the countries belonged to Qin. With the approval of the State Council, the Yan'an area was abolished and the prefecture-level Yan'an City was established.
Yan'an City is located in the northern part of Shaanxi Province, in the middle reaches of the Yellow River. It has districts and counties under its jurisdiction, with a total land area of 10,000 square kilometers and a total population of 10,000. It is one of the first batch of historical and cultural cities announced by the State Council, a national outstanding tourist city and three major educational bases for patriotism, revolutionary tradition and Yan'an spirit.
Introduction to Stone Sand Making Machine
Stone Sand Making Machine, also known as impact sand making machine, is a high-efficiency gravel with domestic, international and leading levels developed based on the actual situation of domestic sand making production. Equipment. This series of sand making machines is widely used in the fine crushing and coarse grinding of metal and non-metallic ores, cement, refractory materials, abrasives, glass raw materials, construction aggregates, artificial sand making and various metallurgical slags, especially for medium-hard, Especially hard and abrasive materials such as silicon carbide, emery, sintered bauxite, magnesia, etc. have advantages over other types of crushers. Used in conjunction with hydraulic protective jaw crusher, it can handle various metallurgical slags. It is suitable for construction sand and road construction sand and gravel.
The working principle of the stone sand making machine
To put it simply, the stone sand making machine uses the stone-on-stone principle, which means that the stones collide with the stones accelerated and thrown out by the impeller during the natural falling process, so as to achieve Broken purpose! When the accelerated stones collide with the naturally falling stones, they form a vortex, and are broken again during the return process, so the wear on the counterattack plate of the machine is very little during operation
Stone Sand Making Machine Equipment Advantages
Simple structure, low cost, smooth operation, high efficiency and energy saving. The material in the impeller and whirlpool crushing chamber is self-lining, which greatly reduces the cost of wear parts and maintenance workload, and effectively solves the crushing process of glass and other raw materials. The iron contamination problem in the machine and the steel jamming problem during the steel slag crushing process are eliminated. The clever internal air flow self-circulation eliminates dust dispersion.
The structure is novel, unique, simple and reasonable, the operation is balanced, and the operating cost is low
Stone hits stone and stone hits iron. The device state can be freely switched to make sand and gravel. One machine has multiple uses. Stone-on-stone technology reduces component wear and reduces production costs.
Low energy consumption, high output, large crushing ratio, energy saving and environmental protection.
It has shaping function, the product is cube-shaped and has high packing density.
During the production process, the stone can form a protective bottom layer, making the machine body wear-free and durable.
A small number of easy-to-wear parts are made of extra-hard wear-resistant materials, which are small in size, light in weight, and easy to replace parts.
Self-circulating air system reduces dust.
It is less affected by the moisture content of the material, and the moisture content can reach about %.
The main shaft bearing is circulated and lubricated by a thin oil station, and there is a spare pound to ensure continuous oil supply to the main engine. Automatic control and accident alarm can be realized.
() The top cover is lifted through the hydraulic system, which is easy to operate.
Technical characteristics of stone sand making machine
High crushing efficiency, fine crushing and coarse grinding functions
Simple structure, convenient installation and maintenance, low operating cost
, Non-crushing It has strong material capacity and is little affected by the moisture content of the material. The moisture content can reach %
. The product has excellent particle shape, in the shape of a cube, with very low needle-flake content. It is suitable for aggregate shaping, artificial sand making and high-grade highways. Aggregate production
The products have high packing density and minimal iron pollution.

Stone Sand Making Machine Maintenance
Routine maintenance of the sand making machine is essential. The sand making machine must be given sufficient downtime regularly and the sand making machine must be observed regularly. Check the internal wear of the machine. If there is any wear, it should be replaced or repaired in time. Also note that the sand making machine must not be opened for observation during normal operation to avoid dangerous accidents.
When the sand making machine is working for hours, an appropriate amount of grease should be added. When the working hours are reached, the main shaft assembly should be opened to clean the bearing. If the sand making machine is working for hours, it must be replaced with a new one. of bearings.
The tensioning force of the transmission triangular tape should be adjusted appropriately to ensure that the triangular tapes should be grouped and matched so that the length of each group is as consistent as possible. It should be adjusted so that the current difference between the two motors does not exceed.
During the work process, because the sand making machine is a high-speed running equipment, special attention should be paid to safety. Workers should stay away from the equipment. If they need to go on the machine for repairs, they must cut off the power before proceeding.
