Welcome: Sandman stone crusher

What is a small hammer mill?

A small hammer mill is a machine that uses high-speed rotating hammers to crush stones. People also call it a hammer sand crusher.

It's a multi-functional crushing device,and has a small size, a simple structure.One person can operate it.

This small hammer mill is suitable for medium-hard materials like limestone, coal gangue, bricks, gypsum, and pebbles. It has high crushing efficiency.

Its output capacity is 8-15 tons per hour, perfectly meeting the needs of small construction sites, and small sand and gravel plants. It's diesel-powered and can operate without an electric grid.

What is the feed size of small hammer mill?

This small hammer mill has a 400×600mm feed opening. The maximum feed size should not exceed 100mm; larger materials can cause jamming and damage to the machine.

You can feed common construction waste, bricks, and coal directly without secondary processing, which saves time and labor. The rationally designed feed opening ensures smooth feeding, prevents clogging, and increases working efficiency.

What is the output capacity of this small hammer mill?

This small hammer mill has a stable output, producing 8-15 tons per hour. It can produce 12-15 tons per hour for ordinary limestone and bricks, and up to 8 tons per hour for slightly harder stones. Compared to similar equipment, this output is very good. It can produce 80-120 tons of material per day in 8 hours, which is more than enough for small construction sites.

What is the Output Particle Size of the small hammer mill?

The output particle size of this crushing machine is adjustable. Our model can produce particles as small as about 5mm. This creates fine material you can use as sand without more processing. You can use it for concrete work, brick making, and road paving.

What is the Application of small hammer mill?

This small hammer crusher has a wide range of applications, covering almost all small material crushing scenarios:

1. Construction sites: Crush construction waste, concrete blocks, and bricks. Turn waste into recycled sand and gravel. This saves money and helps the environment.

2. Small sand and gravel plants: Process limestone and granite into construction sand, with low investment and fast returns.

3. Small mining sites: Crushing ore for slag treatment, without relying on large equipment;

4. Coal industry: Crushing coal blocks and coal gangue for power plant and boiler fuel;

5. Brick and tile factories: Crushing raw materials for brick making sand;

6. Rural infrastructure: Building houses, paving roads, and laying foundations, using locally sourced materials and reducing transportation costs.

What is Advantages of small hammer mill?

1. Diesel powered, works without electricity: No power grid is needed.

You can use it in fields, mountains, and temporary sites. It has long range and low fuel use.

2. Simple structure and easy maintenance: No complex parts.

One person can operate it. You can replace the hammers simple. You don’t need a professional. This saves labor costs.

3. Compact size, easy to move: It uses less than 2 square meters, so it can fit in small spaces.

4. Uniform output, high quality: The output particle size is easy to control. The material is very uniform, about 5 mm. Engineers can use it directly in projects without more screening. The desired particle size can be adjusted according to customer requirements.

5. Wear-resistant and durable, long lifespan: The hammers use high-chromium material. They are wear-resistant and durable. One set can last 1 to 6 months. The maintenance costs will stay low.

6.The hammer crusher's sealed structure eliminates dust pollution and ash leakage in the crushing workshop.

What is Working principle of small hammer mill?

The working principle of this hammer crusher machine is very simple. The diesel small hammer mill mainly relies on impact energy to crush materials. During operation, the motor drives the rotor to rotate at high speed.

1. Feeding: Stones are fed into the feed inlet and fall onto the high-speed rotating rotor.

2. Crushing: The hammers on the rotor rotate at high speed, smashing the stones violently and crushing them instantly. The crushed stones then hit the liners on the machine casing for secondary crushing. The stones also hit each other, making the crushing process even finer.

3. Discharge: Material smaller than the screen mesh size leaks out through the screen, becoming the finished sand. Larger pieces stay inside, and the hammers keep crushing them until the machine can discharge them.

The entire process is fully automatic, with one-button start, requiring no constant monitoring, making it extremely convenient.

What is Main Wear Parts of small hammer mill?

The wear parts of this small hammer crusher are very simple.They include only three categories.This makes replacement cheap and quick:

1. Hammers: The core wear part, directly contacting the stones, and experiencing the fastest wear;

2. Screen Plate: Controls the output particle size, also experiencing relatively rapid wear;

3. Liners: Protect the machine casing and reduce wear.

You can buy these parts at low price. A full set costs only a few hundred US dollars. You can replace them yourself without contacting after-sales service; it only takes a few minutes and won't disrupt your work.

What is Common Problems During Operation of small hammer mill?

New operators may encounter a few minor issues. Knowing these beforehand will help you easily resolve them:

1. Material Jamming: Mostly caused by feeding material that is too large (over 100mm) or too fast.

Solution: Don't feed too much or too large a quantity of material; slow down the feeding speed.

2. Increased Output Particle Size: The screen plate is worn, or the gap between the hammers has widened.

Solution: Replace the screen plate and the hammers.

3. Excessive Machine Vibration: Uneven hammer wear or loose foundation bolts.

Solution: Replace the hammers and tighten the bolts.

4. Insufficient Diesel Engine Power: Insufficient diesel fuel or excessive machine load.

Solution: Fill the fuel tank and reduce the feed rate.

How Often Should You Replace Wear Parts for this small hammer mill?

The replacement cycle for wear parts varies depending on the material’s hardness and how often you use the parts. Here are some reference values:

1. Hammer: For limestone and bricks, one set can last 15 to 30 days (about 500 to 1000 hours). For hard pebbles, replace it every 7 to 15 days.

2. Screen plate: More durable than a hammerhead. It usually lasts 2 to 5 months. Replace it when the output particle size gets much larger.

3. Liner plate: Most wear-resistant, lasts 3-6 months, replace when severely worn.

Wear parts for small equipment cost very little. They are usually only a few tens of USD.

This cost is negligible compared to the equipment’s revenue. Moreover, parts are easy to buy and replace, and downtime stays under one hour. This avoids delays to the construction schedule.

It has seven key advantages.

1.It does not need electricity.

2.It is easy to move.

3.It is easy to maintain.

4.It has a low cost.

5.It crushes efficiently.

6.It produces good-quality output.

7.It has low-cost and easy-to-replace wear parts, and is simple to operate.

This small diesel-powered hammer mill with an hourly output of 8-15 tons is a "money-making tool" for small projects and construction sites.
