Bluestone crusher

Double machinery design and manufacture complete plants for the bluestone crushing. We offer the entire range of services starting from raw material selection right upto manufacture of the finished product.
This bluestone is literally peeled off of the huge slab that was unearthed at a quarry. The sides of the stone are cut using saws in order to produce pieces that will create a pattern, but the top stays natural.

Sand Crushing Plant for Sale

In sand crushing plant The raw materials are first placed into elementary-crushing machine (jaw crusher) via vibrating feeder for crush, and so the elementary products are transferred through belt conveyor for your secondary-crushing machine (cone crusher) for secondary crushing. The vibrating screen separates the secondary products into two kinds. Usually the one satisfying the traditional with the Vertical Shaft Impact crusher (sand-making crusher) is going to be conveyed for the sand-making machine and be finished products after being washed through the sand washer. Another kind will be restored for the secondary-crushing machine being crushed again.image

Once the input size your materials includes a smaller footprint than 40mm, we recommend you the sand making flow designed with VSI5x series sand making machine, vibrating screen, sand washing machine, etc; otherwise, there may be another solution created for you, equipped with vibrating feeder, jaw crusher, impact crusher (optional), cone crusher, VSI5x series sand making machine, vibrating screen and sand washer.

The flow chart of silica sand processing is:

The quartzite (quartz sand) is mined from deposit quarry then your recycleables is going to be transferred to a stockpile for Primary crushing. Inside the Primary jaw crusher, the raw quartz sand is fed via a vibrating feeder from hopper. After primary crushing, the crushed quartz is going to be fed into cone crusher for further crushing,it will probably be sent to VSI crusher (sand making machine) for final fineness crushing.

After crushing, the quartz sand will probably be sieved into different grades by vibrating screen. The grain size fulfill the demands is going to be collected, as the others is going to be utilized in sand making machine for further crushing.

For river sand, our screening mining machine may also sieve the river sand into diffferent grades based on the clients’ demands. The common grain sizes of silica sand are: 0-0.5mm, 0.5-1mm,1-1.5mm, 1.5-2mm,2-4mm. These sand is popular in building, construction and foundry industries.

Sand Screening, Flotation and Drying

The sand flotation process is primarily accustomed to remove the iron bearing heavy minerals in glass sand crusher . The minerals are usually just like the iron bearing minerals described within the gravity section. Occasionally, flotation can also be used to remove mica.

In The united states, all glass sand is dried at the silica processing plant just before shipping towards the glass manufacturing plant. The advantage of dried sand towards the glass producer is the better ability to accurately appraise the batch ingredients, better material flow characteristics, and mixing of batch ingredients. The fee to dry the sand, however, is borne by the producers with the silica sand. Glass Sand Drying may be the single most expensive unit operation in the silica plant. As the cost of fuel continuously increases, it becomes much more of a cost burden.

Jaw Crusher for Sale

Jaw Crusher Overview

jaw crusherJaw Crusher is one of the main types of primary crushers in a mine or ore processing crusher plant and also is one of the most widely used crushing equipment in mining industry. This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. Because it is primary crusher, Jaw crusher is designed for long life service with minimum maintenance for hard, tough, abrasive material and overload high capacity.

Jaw Crusher Parts

Jaw crusher mainly consists of two jaw plates, one is fixed jaw plate, the other is movable jaw plate. In addition, there are flywheel, toggle plate whose application is to protect jaw plate, and tension rod used to adjust the size of discharging open to meet different jaw crusher need.

Jaw Crusher Application

Jaw Crusher can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc. In these industryes Jaw crusher is widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc.,whose pressure resistance strength is under 200Mpa.

Jaw Crusher Main Features and Benefits

  1. Flexible capacity and high reliability
  2. Simple structure and easy maintenance, jaw crusher mainly consists of two jaws
  3. Over-loading protection, jaw crusher has toggle plate to protect it.
  4. Stable performance, low operating cost
  5. High crushing ratio which can reach 4-6, also high resistance to friction, abrasion and compression with longer operating life span.

Jaw Crusher Working Principle

Primary jaw crushers are typically of the square opening design, and secondary jaw crusher is of the rectangular opening design. Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw board, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates decide the crusher product size gap, or the size of the crushed product from the jaw crusher. The rock remains in the jaw until it is small enough to pass through the gap at the bottom of the jaws.

Jaw Crusher Installation Instructions

  1. jaw crusher is installed by the factory, the user should be checked after the receipt of the jaw crusher machine and eliminate the various problems arising from transport, and then install it.
  2. rack installation, the vertical plane at the end of the level of tolerance of 0.5mm / m, the horizontal level degrees (measured on the spindle) Tolerance of 0.15 mm / m.
  3. comprehensive inspection before starting the jaw crusher machine. The fastening of the fixed parts, each part of the ubrication as well as V-belt tension level is to check the suitability of the like should be the focus.
  4. Check the overall circuit after cuting off jaw crusher switch, and a clear sign hanging switch.
