Detailed explanation of the complete production process of manufactured sand and configuration equip

In order to obtain high-quality machine-made sand aggregates, the sand making equipment can be adjusted and replaced according to the size of the machine-made sand raw materials, the specifications of the finished sand, the investment cost and other factors.

The configuration of machine-made sand production includes vibrating feeder, belt conveyor, jaw crusher, cone crusher, sand making machine, vibrating sand washing machine and other equipment, the configuration of machine-made sand production line depends on the nature of the material, if the material is harder and the cone crusher can be used when the secondary crushing is hard, and the impact crusher can be used if the material is brittle; If the particle size of the material is small and conforms to the feed size of the sand making machine, the jaw crusher can be omitted.

Jaw crusher is one of the main equipment of sand making production line, which is used for coarse crushing process, with high crushing efficiency and large crushing ratio.

The cone crusher is usually used in the secondary crushing process, which is suitable for the crushing of stones with high hardness, and the equipment is wear-resistant and has a long service life.

After the sand making machine is used in the crusher, the crushing principle of stone to stone or stone to iron is adopted, the crushing efficiency is higher, the particle size of the machine-made sand produced is uniform, the crushing cavity is large, and the production capacity is high.

4. a vibrating screen

Responsible for screening machine-made sand of different particle sizes, the vibrating screen has a simple structure, and the vibrating screen can be customized according to the production needs of users, and the vibrating screen has high screening efficiency.

5. Sand washing machine

The sand washing machine is used to clean the machine-made sand processed by the sand making machine, clean the soil and impurities, and the sand washing machine has wheel bucket type, spiral type and three-in-one type, and users can choose according to their actual needs.

6. Belt conveyor

The belt conveyor is made of high-quality materials, which is conducive to the friction between the stone and the belt, and has the advantages of wear-resistant and life-lasting benches, and the length of the conveyor can be customized according to the actual production needs of users.

The machine-made sand production line is a process that makes the high-quality sand and gravel aggregates required in infrastructure construction by processing the mined large stones (pebbles, river pebbles, granite, marble, basalt, etc.) through orderly coarse crushing, medium crushing, screening, sand making, sand washing and other links. According to the nature of the material, the size of the finished product, the hourly output, the operating environment, the investment cost, etc., the configuration equipment of the machine-made sand production process is different.

The sand making machine sand process is as follows:

First of all, the stone is preliminarily crushed by the coarse crusher, and then, the coarse material produced is transported to the fine crusher by the belt conveyor for further crushing, and the finely crushed stone is screened out by the vibrating screen to separate two kinds of stones, and the stones that meet the feed particle size of the sand making machine are fed into the sand making machine, and the other part is returned to the fine slope.

Part of the stones of the sand making machine are made into sand, which is cleaned by the sand washing machine (optional) to make finished sand, and the other part is crushed again by the sand making machine. The machine-made sand production line is composed of a combination of equipment such as vibrating feeder, jaw crusher, sand making machine, vibrating screen and belt conveyor.

A complete sand making production line configuration mainly includes: crusher, sand making machine, sand washing machine, feeder, conveyor, and screening machine. The workflow is:

1. Feeding: The material is evenly fed into the jaw crusher by the vibrating feeder first.

2. Coarse crushing: Coarse crushing is carried out by the jaw crusher.

3. Medium and fine crushing: The materials after coarse crushing are sent to the impact crusher or cone crusher by the belt conveyor for medium and fine crushing processing.

4. Sand making: The materials processed by medium and fine crushing are sent to the sand making machine by the belt conveyor for sand making and shaping.

5. Screening: The materials after sand making are sent to the circular vibrating screen by the belt conveyor for screening, and the unqualified materials are sent to the sand making machine again for sand making processing.

6. Sand washing: In the last process, the qualified materials for sand making are sent to the sand washing machine with a belt conveyor for cleaning.

Such a sand making production line can process raw materials from large stones to machine-made sand specifications below 5mm after multiple crushing and screening. The equipment involved in the whole process from crushing, sand making to screening, conveying and other equipment types is also relatively large, and such a sand making production line is configured to range from hundreds of thousands to millions. Let's take the actual configuration case as an example:

Material: granite.

Output: 500-600t h

Discharge size: 0-5mm, 5-10mm, 10-20mm

Equipment configuration: two FH1560 vibrating feeders, two PE1200 1500 jaw crushers, two HST315 single-cylinder cone crushers, two S5X3075-3T, three HPT500 multi-cylinder cone crushers, two S5X3075-3T vibrating screens, two VSI6X1263 sand making machines, four S5X3075-3T vibrating screens and two XSD3620 sand washing machines.

This is a production of 500-600 tons per hour, if it is other volumes, the equipment model will be different, so that the price point of the entire configuration changes. Although the whole sand making process is simple, the scheme configuration still requires a certain degree of professionalism, so as to ensure the high input-output ratio of GA production capacity and G cost.

Manufactured sand production process.

The stone is evenly sent to the jaw crusher for coarse crushing by the vibrating feeder, the material after coarse crushing is sent to the impact crusher for crushing again, the crushed material is sent to the sand making machine by the belt conveyor for sand making, the sand and gravel material coming out of the sand making machine is screened by the vibrating screen, and the material that meets the requirements is the finished product, which falls into the finished sand pile by spraying dust reduction. If it does not meet the requirements, return to the sand making machine to re-make the sand and then go to the vibrating screen for screening. The dust generated in the vibrating screening process enters the pulse dust collector after passing through the separator.

There are many raw materials that can be used to survive machine-made sand, common river pebbles, pebbles, granite, basalt, quartz stone, sandstone, tailings, construction waste, etc. can be used to produce machine-made sand.

The production process of machine-made sand is more concerned by most users, the following shows you a common process flow chart, under normal circumstances, large pieces of rough stone (such as pebbles, bluestone, quartz stone, granite, dolomite, etc.) after feeding, conveying, crushing, sand making, screening, sand washing and other processes, you can get high-quality sand and gravel aggregates, according to the size of raw materials, finished product specifications, investment costs and other factors, the equipment of the following process can be adjusted and replaced.

The conventional sand production line process mainly includes: feeding, crushing, sand making, screening, sand washing, etc., the equipment includes vibrating feeder, crusher, sand making machine, circular vibrating screen, sand washing machine, the production model of the equipment is different, the specific production line equipment can be combined according to their own production needs, site and other actual conditions, we must choose a reliable manufacturer, by professionals to design environmentally friendly, reasonable and efficient sand production line, reasonable with a full set of equipment.

Various engineering construction has led to a significant increase in the demand for foundation construction materials, but now the state controls natural river sand and sea sand very strictly, and a large number of mining is not allowed for environmental protection. Therefore, machine-made sand has become a good substitute, and the ** of machine-made sand is lower than that of natural sand.

Understand the process of the sand making production line and choose a sand making machine that is more suitable for you.

The machine-made sand production line is mainly composed of a feeder, a crusher, a sand making machine, a belt conveyor, and a center console. For the crusher, choose the right crusher according to the fineness of the finished product you need.

Most of the raw materials used in the sand production line are cheap raw materials and large quantities. For example, river pebbles, perlite, granite, basalt, limestone, quartz and other stones with high hardness. and aggregates with lower hardness, glass, ceramics and other construction waste.

The machine-made sand produced by the sand making production line is widely used in various industries that have a demand for sand and gravel aggregates. For example, it provides good quality sand and gravel aggregates for fireproof materials, road and bridge construction, hydropower dams, and concrete batching plants. In order to cope with different production sites and requirements, the production line can be split and combined, flexible collocation, and ensure efficiency.

Next, we will briefly introduce the basic process flow of sand making and crushing production line.

The machine crushes and makes sand through two methods: "stone to stone" and "stone to iron". The raw materials are continuously sent to the crusher through the feeder, and after many crushing, the stones that meet the specifications are sent to the sand making machine, and after the operation of "stone ontose" or "stone ontose", the final finished product is discharged by the discharge port. After screening, the finished machine-made sand is obtained, and a set of basic sand production line process is basically completed.

The machine-made sand technology has been very mature, which can greatly improve the degree of automatic operation of the production line, and has many advantages: low operating cost, low energy consumption, large output, easy machine maintenance, and the finished sand grain shape produced is good, comparable to natural sand, and meets standards at all levels.

Different customer needs are certainly different, according to the specific requirements of customers, determine the composition of the sand production line. The manufacturer will give the most professional advice and technical support through the needs of customers and the inspection of the production site, and configure it according to many production conditions to ensure high efficiency and economy.

It's good to be together、Hmmm! Why don't you do it at home.
