Sand maker can also be called artificial sand maker, and at present it has replaced traditional sand making machines such as hammer crusher, roll crusher and rod mill and become the main equipment of the artificial sand making industry. The artificial sand maker produced by our company is widely used for the fine crushing of such materials as all kinds of ores, cement, refractory, bauxite, and emery and glass raw materials.

In the construction industry, sand making machinery has been widely used for making artificial sand, small-sized stone materials and metallurgical slag, and it has also been used in construction projects and road construction field for producing cushion ply material, pitch concrete and cement concrete aggregate.

In the mining industry, energy-saving sand maker is mainly used in the procedure before ball mill for the fine crushing of the ores before they are sent into ball mill, which reduces the grinding time and greatly reduces the grinding cost.

In the ore dry type separation field, the sand particles finely crushed by energy-saving sand maker can be directly sent into dry type strong magnetic separator for separation after classified by vibrating screen.

1. The matched power is low, thus saving electricity. The crushing ratio of the sand maker can reach as high as 36%, and can save 20% of electricity compared with other similar machine types and the running cost is relatively low.

2. After changing the screen board, the machine can be used for both fine crushing and coarse crushing, which is convenient for satisfy the customers’ needs.

3. The quick-wear hammers are made of high chromium alloy material, so that in the material crushing process, the self abrasion is low and the hammers can be reused after reversing the head, for this reason, the service life is extended for over 6 times than that of made of manganese steel.

4. This sand making machinery has high stability and the changing of the spare parts is convenient.

5. The sand making machinery is designed with high reliability and big safety factor, so that it can guarantee the safety of the workers and the equipment in the production process.

When sand maker is working, the materials vertically fall from the upper part of the machine into the impeller rotating with high speed. Under the high-speed eccentric force, some parts of the materials will have high-speed impact and crush with the part of the materials that are distributed around the impeller in the form of umbrella. After the materials hit with each other, they will also have mutual impact and friction in the space between the impeller and the machine shell, and then they will be crushed and discharged from the bottom, thus forming a multiple closed-circuit cycle, and screening machine will be used to control the required granularity of the final products.
