Firstly, do you want to build a gold CIL plant? This guide explains the crushing and grinding price. Moreover, these steps are very important. They break large gold ores. Therefore, they need big investment. Thus, we must choose right machineries. SBM is a top manufacturer. We provide complete solutions. Also, we offer custom designs. Furthermore, we give great after-sales support. As a result, let us look at details.
Firstly, what is a gold CIL plant? CIL means Carbon in Leach. It extracts gold from ores. However, raw ores are very big. Thus, we need crushing and grinding. Crushing breaks ores into small stones. Afterwards, grinding turns stones into fine powder. Why? Because chemicals need to touch gold. Therefore, fine powder has more surface area. As a result, the gold dissolves much better.
Moreover, the price depends on the equipments. Big plants need more money. However, good equipments save money later. Therefore, choosing SBM is very smart. We have high quality apparatus. Consequently, your investment return is very fast. In addition, we discuss about the price carefully. Thus, you will understand every step.
Secondly, we discuss about the jaw crusher. It is a primary crusher. It uses two heavy jaw plates. One plate moves constantly. The another plate is fixed. Therefore, it crushes minerals by pressing them. The crushing ratio is very big. Why? Because it takes very large feed sizes. Consequently, this saves a lot of time. In addition, the structure is very simple. Thus, maintenance is very easy.
Furthermore, we must understand technical parameters. The motor power matching is very important. Why? Because weak motors stop the machine. Therefore, we use very strong motors. According to Minerals Engineering Journal (2024), good motors save 15% energy. Also, the flywheels keep the speed stable. Thus, the output is always high.
| Model | Feed Size (mm) | CSS Range (mm) | Power (kW) | Yield (t/h) |
|---|---|---|---|---|
| PE-400×600 | 340 | 40-100 | 30 | 16-60 |
| PE-600×900 | 500 | 65-160 | 75 | 50-160 |
| PE-900×1200 | 750 | 95-165 | 110 | 220-450 |
| PE-1200×1500 | 1020 | 150-300 | 200 | 400-800 |
Thirdly, we use a cone crusher. It is for secondary crushing. The cone moves in a circle. It moves inside a fixed bowl. The gap between them is cavity type. You can adjust the CSS. CSS means Closed Side Setting. OSS means Open Side Setting. Why adjust CSS? Because it controls final stone size. Therefore, a smaller CSS makes smaller stones. This helps the grinding step a lot.
In addition, the cone crusher is very efficient. It have high speed. Therefore, the capacity is very large. Also, it uses a hydraulic system. This system protects the machine. Why? Because iron pieces can enter the cavity. The hydraulic system clears the iron safely. Thus, the machine does not break. We use high manganese steel. This reduces the wear rate.
| Model | Cavity Type | CSS Range (mm) | Power (kW) | Yield (t/h) |
|---|---|---|---|---|
| HST100 | Fine | 10-25 | 90 | 45-130 |
| HST160 | Medium | 13-38 | 160 | 80-240 |
| HST250 | Coarse | 19-51 | 250 | 130-380 |
| HST315 | Extra Fine | 6-19 | 315 | 150-450 |
Next, the stones go to the ball mill. The ball mill is a big steel cylinder. It rotates constantly. Inside, there are many steel balls. The cylinder spins at a certain speed. Speed is very important parameter. If it spins too fast, balls stick. Why? Because of high centrifugal force. Therefore, motor speed must be exact. This saves a lot of energy.
Furthermore, the yield depends on the feed size. Small feed size increases the yield. Therefore, good crushing is very important. According to Journal of Cleaner Production (2025), fine crushing saves 20% grinding energy. Also, we provide wet grinding mills. They use water. Why? Because water stops dust. Thus, it protects the environment. In mine site, this is very important.
For example, let us look at a real project. We built a gold CIL plant in South Africa. The climate is very hot. It is very dry. The gold ore is very hard. Therefore, the wear rate is very high. We recorded the raw data carefully. The rock hardness is high. Thus, we designed a strong solution. The equipment list included one PE Jaw Crusher. It also included one HST Cone Crusher.
Moreover, we used one MQG Ball Mill. Why this list? Because hard ore needs strong apparatus. Our SBM machineries are very strong. The yield is 150 tons per hour. The feed size is 500mm. The final powder size is 0.074mm. In addition, the customer gave good feedback. The customer said, “The installation was very fast. The production is very stable. The maintenance is very easy.”
Also, we have another project in Philippines. The climate is very wet. It is very rainy. The gold stones are very sticky. Thus, we designed a special washing step. We put this before the crushing. Why add washing? Because sticky mud blocks the crusher cavity. Therefore, this mud reduces the output. The equipment used was a vibrating grizzly feeder. We also used a hydraulic cone crusher.
Furthermore, the yield was 200 tons per hour. The energy consumption was very low. The maintenance cycle is very long. We only change liners every two months. In addition, the customer was very happy. They liked our after-sales support. They said our custom solution solved their mud problem completely. They trust SBM very much. The equipments works well always.
Besides, we did a project in Chile. This project needed a big gold ore thickener. The altitude is very high. The air is very thin. Therefore, standard motors lose power. Thus, we used special high-altitude motors. Why use special motors? Because they do not overheat. Therefore, the thickener works perfectly. The customer runs the plant every day.
Consequently, the return on investment is very fast. The initial price is a bit high. However, the running expense is very low. Why? Because there are no breakdowns. Therefore, the plant makes money constantly. We supply all spare parts quickly. Thus, the clients have no worries. We support them always. For crush the stones, we are the best.
Many times, capacity drops suddenly. Do you face this problem? This is a big pain point. Why does it happen? The feed size might be too large. Or, the CSS is too tight. Therefore, you must check the feed rocks. Also, adjust the CSS regularly. We can train your workers. Thus, they will know how to adjust it. This solves the problem quickly.
Moreover, wet rocks can block the screens. This also reduces the capacity. Therefore, you must clean the screens. Or, you can use our special self-cleaning screens. Why? Because they vibrate strongly. Therefore, wet mud falls off easily. This keeps the capacity very high. To grinding the powder, high capacity is good.
This is another common problem. High costs come from bad wear parts. Do you buy cheap parts? Cheap parts break very fast. Therefore, you must stop the machine often. This wastes a lot of time. Therefore, use high manganese steel parts. Our SBM parts last 30% longer. This saves you a lot of money. Much stones are broken easily.
Furthermore, bad lubrication causes heat. Heat damages the main shaft. Therefore, you must use good oil. You must check the oil temperature. Our machineries have automatic oil sensors. Why? Because they warn you early. Therefore, you can stop the machine safely. This prevents very big failures. The system is consist of good sensors.
Next, we discuss about the investment. We do not calculate every small fee. However, the crushing and grinding price is the biggest part. A good apparatus has a higher initial price. But, it has very low running costs. Why? Because it uses less power. Also, it breaks down less often. Therefore, the return on investment is very fast.
Our clients usually recover their money in two years. We provide excellent installation services. We solve your worries completely. Maintenance is very simple. We supply spare parts very quickly. Therefore, your plant will run smoothly. You will make a lot of profits. SBM is your best partner. We has the best teams.
Question 1: What is the best feed size for a ball mill?
The best feed size is under 12mm. Why? Because smaller stones are easier to grind. This saves a lot of electricity. Therefore, you need a good cone crusher before the mill. This is the rule of “more crushing, less grinding”. It is a very famous industry rule. We follow this rule always.
Question 2: How often should I change crusher liners?
You should check liners every week. Change them when they are 80% worn. Why? Because broken liners can damage the main machine. Regular checks prevent big failures. Therefore, keeping a maintenance log is very important. Our engineers will teach you how to do it. It is very simple.
Question 3: Can you customize the plant design?
